Rotary Rock Tumbler Instructions

Rotational Rock Tumbler Instructions The most widely recognized kind of rock tumbler is a revolving drum tumbler. It shines shakes by mimicking the activity of the sea waves. Rotational tumblers clean shakes significantly more rapidly than the sea, however it despite everything requires some investment to go from unpleasant rocks to cleaned stones! Anticipate that the procedure should take at any rate a month all the way. Utilize these guidelines as a beginning stage for your tumbling. Track the sort and amount of rock and coarseness/clean, and span of each progression. Utilize this data to refine your strategy for the best outcomes. Rock Tumbler Materials List Revolving tumblerRocks (no different estimated hardness in a load)Plastic PelletsSilicon Carbide Grits (You may include a 400 work SiC step, whenever wanted, before polishing)Polishing Compounds (for example alumina, cerium oxide)Lots of Water The most effective method to Use a Rock Tumbler Fill the barrel 2/3 to 3/4 loaded with rocks. In the event that you dont have enough shakes, you can add plastic pellets to compensate for any shortfall. Simply try to utilize those pellets just for coarse cleaning and utilize new pellets for the cleaning stages. Remember that some plastic pellets coast, so ensure you add them to the correct volume beforeâ adding water.Add water so you can see it between the stones however don't totally cover the stones.Add coarseness (see graph below).Make sure your charged barrel falls inside the weight recompense for the rotor to be used.Each step runs for at any rate seven days. For the initial step, expel the barrel following 12-24 hours and open it to discharge any gas development. Resume tumbling. Dont be hesitant to open the barrel occasionally to ensure a slurry is shaping and to check the advancement of the procedure. The tumbler ought to have a uniform tumbling sound, not sound like sneakers in a dryer. On the off chance that the tumbling isn't uniform, check the degree of the heap, arrangement of slurry, or blend of rock sizes, to ensure these things are ideal. Keep notes and have some good times! Allow the unpleasant to granulate (60/90 work for hard stones, start with the 120/220 for delicate stones) run until the entirety of the sharp edges have been knocked off the stones and they are quite smooth. You can hope to lose about 30% of each stone during the tumbling procedure, with practically the entirety of the misfortune during this initial step. On the off chance that the stones are not smoothed following 10 days, you should rehash the progression with new grit.After a stage has been finished, flush the stones and the barrel completely to expel all hints of the coarseness. I utilize an old toothbrush to get into the difficult to-arrive at zones. Put aside any stones that are broken or have pits or splits. You can add them to the initial step of the following cluster of stones, however they will lessen the nature of the entirety of your stones on the off chance that you leave them in for the following step.For the subsequent stage, you again need the stones to fill the barr el 2/3 to 3/4 full. Add plastic pellets to compensate for any shortfall. Include water and coarseness/clean and continue. The keys to progress are making sure there is no sullying of steps with coarseness from the past advance and evading the compulsion to proceed onward to the following stage too soon. Barrel Coarseness Mesh 60/90 120/220 Prepolish Clean 1.5# 4 T 4 T 6 T 6 T 3# 4 T 4 T 6 T 6 T 4.5# 8 T 8 T 10 T 10 T 6# 10 T 12 T 12 T 12 T 12# 20 T 20 T 25 T 25 T Accommodating Tips for Perfectly Polished Rocks Try not to over-burden your tumbler! This is a main source of belt breakage and engine wear out. If all else fails, gauge your barrel. A barrel for a 3-lb engine ought not surpass a load of 3 pounds when accused of rocks, coarseness, and water.Oil the tumbler bushings with a solitary drop of oil, however don't try too hard! You don't need oil on the belt, as this will make it slip and break.Resist the impulse to tumble rocks with splits or pits. Coarseness will get into these pits and pollute ensuing advances, destroying the clean of the whole burden. No measure of scouring with a toothbrush will evacuate the entirety of the coarseness inside a pit!Use a reasonable burden that incorporates both enormous and little shakes. This will improve the tumbling action.Make sure all stones in a heap are of the equivalent inexact hardness. Something else, the milder stones will be eroded during the cleaning procedure. A special case to this is the point at which you are intentionally utilizing milder stones to fill/pad a load.Dont wash coarseness down the channel! It will make a stop up that is impenetrable to deplete more clean. I wash the coarseness ventures outside utilizing a nursery hose. Another alternative is to flush the coarseness into a pail, for later removal some place other than your pipes. Dont reuse coarseness. Silicon carbide loses its sharp edges after about a weeks tumbling time and gets futile for grinding.You can reuse plastic pellets, yet take care to abstain from polluting the cleaning stages with coarseness. Utilize separate plastic pellets for these stages!You can include heating pop, Alka-Seltzer, or a Tums to a heap to forestall gas construct up.For smooth waterway rocks or for any gentler stones (for example sodalite, fluorite, apatite), you may preclude the principal coarse coarseness step.For gentler stones (particularly obsidian or apache tears), you need to slow the tumbling activity and keep the stones from affecting each other during cleaning. A few people have achievement including corn syrup or sugar (twice as much as the measure of prepolish and cleaning operator) to thicken the slurry. Another choice is to clean the stones dry (as in no water) with cerium oxide and cereal. It is safe to say that you are keen on utilizing a vibratory tumbler to clean shakes? At that point attempt these guidelines.

Incompatibilism V. Compatibilism free essay sample

There are two winning incompatibilist sees concerning choice, hard Determinism or Libertarianism. The previous states that in the event that determinism is valid, at that point through and through freedom is nonexistent and people are basically robots following a way decided for us from quite a while ago and characteristic laws. The last denies that determinism is valid and in this manner seems to acquaint irregularity as a clarification with represent through and through freedom. Compatibilists guarantee that through and through freedom and determinism can exist together. For the extent of this paper I will consider the three winning contentions for the presence of through and through freedom or scarcity in that department and contend that a compatibilist see conceivable view for the presence of unrestrained choice. First I will endeavor to show that determinism and through and through freedom can coincide, along these lines dismissing the Hard Determinism contention. Next I will guarantee that Libertarianism doesn't successfully preclude determinism, by concentrating on the Quantum Mechanics reaction. At last I will endeavor to call attention to a connection among obligation and compatibilism. We will compose a custom article test on Incompatibilism V. Compatibilism or on the other hand any comparative subject explicitly for you Don't WasteYour Time Recruit WRITER Just 13.90/page Determinism and Compatibilism The proposal of causal determinism expresses that each occasion has a reason and that human, an occasion, is no special case to the standard. Completely put, on the off chance that we know the entirety of the physical realities and causal laws about a circumstance, we can figure out what will happen straightaway. Implying that convictions and activities cause our activities, and our past causes our convictions and wants (I. e. guardians/grandparents). The Hard Determinist contention, which streams from the theory of causal assurance, expresses the accompanying : 1)Everything we do is brought about by powers over which we have no control. 2)If our activities are causes by powers which we have no control, we don't act openly. )In this way, we never act openly. The Hard Determinist contention seems, by all accounts, to be in struggle with whether we act openly instead of â€Å"free will† or our capacity to settle on decisions. Utilizing a psychological study I will endeavor to cl arify the distinctive between acting openly and unrestrained choice. Late investigations show that liquor addiction is a multifaceted issue brought about by a lot of qualities, which increment one’s inclination to turning into a heavy drinker, and natural variables . James is a College Park understudy that goes to The Thirsty Turtle day by day since he appreciates the flavor of liquor and the impression of being smashed. It unquestionably appears that James is free in deciding to drink each day, yet his choice to drink is caused be past components. James’ guardians were heavy drinkers who drank openly before James when he was more youthful, hence notwithstanding adding to his hereditary inclination; his folks gave a liquor advancing condition. One night while drinking, James and Billy leave the bar amazingly inebriated. Nor is fit to drive, however James takes the haggle inevitably associated with a deadly mishap which executes his companion Billy. James falls into despondency after Billy’s passing, holds a firearm to his head, and pulls the trigger. The significant inquiry is whether James acted openly? One can concur that James ended it all of his own â€Å"free will† or decision at the same time, from determinism one can say that James didn't act openly. In the event that we glance back at Billy’s interminable causal course of events, it becomes obvious that James didn't act uninhibitedly: He was the child of drunkards and brought up in a heavy drinker condition, his granddad was a drunkard, and his predecessor from Columbus’ revelation, a Native American, turned into a heavy drinker after the pioneers acquainted him with liquor. Characterizing â€Å"free will† as one’s capacity to pick isn't in strife with determinism. Determinism despite everything wins in light of the fact that, similarly as with the model with James, one doesn't act unreservedly because of their foreordained reasons for his liquor abuse. Up until now, I have endeavored to show that choice, under the definition expressed above, and determinism can exist together. Compatibilism gives a superior record of through and through freedom contrasted with Hard Determinism since it shows that unrestrained choice can exist and along these lines outlines that Hard Determinism is right now mistaken on the grounds that it doesn't represent choice. Libertarianism †Is Randomness and Answer? While compatibilism dismisses the second reason of the Hard Determinist contention, Libertarianism dismisses the main reason †the possibility that determinism exists to the extent that it applies to people. There are three general libertarian reactions that endeavor to dismiss determinism: experience/contemplation, responsibility, and quantum hypothesis. For this paper, I will cover what has all the earmarks of being the most convincing reaction, quantum hypothesis. â€Å"According to quantum mechanics, a foundation of present-day material science, the principles that administer the conduct of subatomic articles are unchangeably probabilistic. † For instance, if one somehow managed to shoot a photon shaft through a X-beam film as per quantum mechanics, best case scenario, we can just decide the likelihood of a solitary photon’s capacity to infiltrate the film, however not which specific photon endures . Quantum hypothe sis brings haphazardness into the universe, yet does the irregular movement of subatomic particles invalidate determinism and permit us to drop the thought of determinism for each fiber of the universe? I don’t accept so. As Rachels would state, Randomness and opportunity are totally unique. My concern with quantum mechanics is that it doesn't preclude determinism. Take the accompanying model; we dispatch a shot inside a vacuum (no air obstruction). We know, from Newtonian Physics, the way the shot will take, the speed at the highest point of its flight, and the hour of its flight. These factors are continually verified in material science labs, and the occasion is causally decided as in we can follow gravity (the fundamental impact on shot movement) back to the development of the universe and earth. Since we can decide shot movement I don't perceive how from quantum mechanics, it follows that determinism doesn't exist. Obligation under Compatibilism Determining whether we are liable for an activity relies upon whether the activity is merits fault or recognition. Through and through freedom is an important part of obligation, on the off chance that we affirm that unrestrained choice doesn't exists, likewise with the Hard Determinist contention, at that point duty would be futile since one can't pick an activity. James Rachels gives a record of obligation dependent on three conditions : 1. You more likely than not done the demonstration being referred to 2. The demonstration should in some sense have been off-base 3. You should have no reason having done the demonstration. *Viable reasons: botches, mishaps, compulsion, numbness and craziness. The inverse applies for admirableness, yet pardons are replaces with conditions practically equivalent to pardons. So I'm not catching this' meaning for compatibilism? Since we do have through and through freedom agreeing compatibilism, we are answerable for our activities insofar as these activities are excellent or reprehensible under the Rachels record of duty. With this paper, I trust that I have endeavored to clarify that hard determinism’s imperfection is that it doesn't represent through and through freedom. Libertarianism’s well known reaction, quantum mechanics, neglects to expose clearly decided occasions (shot in a vacuum). Hence leaving compatibilism, with the reconsidered meaning of through and through freedom, as the best record with the expectation of complimentary will.

Tips on How to Reduce Your Anxiety

Tips on How to Reduce Your Anxiety GAD Coping Print Strategies to Reduce Your Anxiety By William Meek Updated on February 24, 2020 Generalized Anxiety Disorder Overview Symptoms & Diagnosis Causes Treatment Living With In Children Hero Images / Getty Images Everyone worries about things sometimes. But people with generalized anxiety disorder (GAD) experience an exaggerated amount of worry, which can become debilitating. Why We Worry Worrying is a cognitive symptom of anxiety. ?At a moderate level, anxiety can be helpful. It motivates a person to take something seriously, to solve a problem, to consider the implications of his or her actions, or to search for reassurance. Is Anxiety Ever Helpful? Sometimes, a person can become stuck in a state of worry that isnt helpful. Here are six strategies to reduce worry and ease anxiety. Make a Plan One thing people often worry about is unforeseen circumstances. Sometimes there are things happening in our lives that are out of our control, such as getting hired for a job. One way to cope with situations like these is to make plans for different possible outcomes. Make a plan as detailed as you need to determine your course of action if you do or do not get the job, which hopefully will take away some of the worry. Do You Have Work Anxiety? Rehearse People also often worry about performances and presentations in front of peers. For school, jobs, and our social lives, we frequently have to make presentations, speak publicly, or talk to friends about something difficult. One way to reduce worry in these situations is to rehearse exactly what you are going to say and do as many times as you need to feel comfortable. Attend to Your Physical Health When our bodies are in optimal health, we have more mental resources available to cope with stress, solve problems, and control our worrying. Health Habits That Can Increase Anxiety Achieve optimal physical health by eating a healthier diet, sleeping more, and being more physically active. It can have dramatic effects on your mood and your ability to cope. Discover the Real Source of Anxiety Sometimes a person worries about things that are a distraction from the things that are really bothering him or her. For example, worrying about an outfit to wear the next day, which provides a distraction from worrying about what is really bothering them, such as a quarrel with a loved one. Being able to trace the source of your anxiety and worry can help you regain control of the situation and take steps to address what is really troubling you. Put Anxiety in The Proper Context A hallmark sign of generalized anxiety disorder is magnifying and worrying about small things, making them more important than they really are. Taking a step back to put your worries into their proper context can be a quick way to reduce their intensity. Break Your Worries Down Worrying tends to make us build a giant mountain of fear and anxiety in our minds, and eventually, we lose sight of what is actually part of the mountain. Taking some time to break down and list the things that are troubling you is a great way to get a handle on things and allows you to make several smaller plans of action, rather than being crippled by having to climb a mountain.

B. Write an Essay in Which You Analyze and Interpret Polly...

Not all marriages have happy endings, not all marriages last forever and moving on can be difficult. That is what the short story Reconciliation, written by Polly Clark, is trying to tell us. The story is written in 1st person because we are able to read what she is thinking and feeling – even when she doesn’t know it: â€Å"It’s my first day, I cycled here† etc. It all starts â€Å"in medias res†, where the reader is thrown into the events and quickly forced to understand everything that is happening. The fact that it’s the narrator who tells the story gives a very good insight into her world and what she is thinking and that is very important when you have to characterize her. The story takes place in an office and we follow the narrator and†¦show more content†¦Vernon has moved on and Laura is still stuck. And with Laura being positive that Vernon has a new girl, Janny, the numbers show that perfectly. Laura is the single number with no match and Vernon is the one with the match. That is also a reason she really wants to find the specific numbers match: â€Å"I want its story. When I know its story I can let it go.† That really shows that Laura can’t move on unless she knows the whole story. Her marriage with Vernon is a big part of the story. As said earlier, they’ve been married for a long time and a lot has changed since they first met. When they first met eachother they talked a lot: â€Å"..It was always what was special about me and Vernon, the talks, the chatting.† But now that has changed: â€Å"..We regard eachother over months of frozen silence†. It’s very easy to notice that she is afflicted with the silence between Vernon and her. She mentions it with following sentence: â€Å"We began our relationship in a bar, and those were our best times, telling each other the truth of our lives in the warm light† and â€Å"News and questions bubble up in my throat, but I cannot speak†. This unfortunately is a very common day nowadays. Sometimes people grow apart and it seems to be the case here. Vernon seems to have accepted that while Laura is in a state of sorrow. Vernon seems to be the one who has the most control over himself and his life. He doesn’t seem as affected as her and she notices: â€Å"He looks so

Double Consciousness in Invisible Man by Ralph Ellison

The Theme of Double Consciousness in the Novel Invisible Man By Ralph Ellison 11/15/2011 Ralph Ellison is one of the few figures in American literature that has the ability to properly place the struggles of his characters fluidly on paper. His dedication to properly depict the true plight of African Americans in this exclusionary society gave birth to one of the greatest novels in American history. Invisible Man is a novel which tells the story of an African American man, and his journey through a society which continuously refused to see him for who he truly was. In the novel Ellison gives us a main character without a name, this at first may shock any average reader but once one falls into the enchantments of the novel,†¦show more content†¦In this journey our main character also see’s the many faces of the black man, and how all of these faces where created in response to the actions of the white man never in response to one’s own actions. Towards the end of the novel the main character finds himself in a difficult predicament as he is being hounded by men who want him dead. Despite this, he manages to find a pair of glasses and a huge hat which he believes would disguise him just enough so that he can escape his potential murderers. As he walks around Harlem in his new guise, many begin to confuse him for someone called Rinehart who seems to be bookie, a pimp, and a preacher all at once. The ability to be so many things is at first attractive to the main character as he slowly begins to sink into the role of Rinehart, however he soon realizes that Rinehart’s multiple identities are merely a reflection of his inauthenthicity. Rinehart has no true self-consciousness and has allowed for others to create his image for him; Rinehart is only identified in the novel by others, never by himself. Rinehart’s character is representative of the notion of Double Consciousness as it shows the black men without the ability or better yet the privilege of self identity.

The gaping hole in the ice now looked like a small swimming pool in the middle of the habisphere. The surface of the two-hundred-foot-deep pool of melted water sloshed for a while against the icy walls of the shaft and then finally grew calm. The waterline in the shaft was a good four feet beneath the glacier’s surface, the discrepancy caused by both the removal of the meteorite’s mass and ice’s property of shrinking as it melts. We will write a custom essay sample on Deception Point Page 27 or any similar topic only for you Order Now Norah Mangor immediately set up SHABA pylons all around the hole. Although the hole was clearly visible, any curious soul who ventured too close and accidentally slipped in would be in dire jeopardy. The walls of the shaft were solid ice, with no footholds, and climbing out unassisted would be impossible. Lawrence Ekstrom came padding across the ice toward them. He moved directly to Norah Mangor and shook her hand firmly. â€Å"Well done, Dr. Mangor.† â€Å"I’ll expect lots of praise in print,† Norah replied. â€Å"You’ll get it.† The administrator turned now to Rachel. He looked happier, relieved. â€Å"So, Ms. Sexton, is the professional skeptic convinced?† Rachel couldn’t help but smile. â€Å"Stunned is more like it.† â€Å"Good. Then follow me.† Rachel followed the administrator across the habisphere to a large metal box that resembled an industrial shipping container. The box was painted with military camouflage patterns and stenciled letters: P-S-C. â€Å"You’ll call the President from in here,† Ekstrom said. Portable Secure Comm, Rachel thought. These mobile communications booths were standard battlefield installations, although Rachel had never expected to see one used as part of a peacetime NASA mission. Then again, Administrator Ekstrom’s background was the Pentagon, so he certainly had access to toys like this. From the stern faces on the two armed guards watching over the PSC, Rachel got the distinct impression that contact with the outside world was made only with express consent from Administrator Ekstrom. Looks like I’m not the only one who is off-the-grid. Ekstrom spoke briefly with one of the guards outside the trailer and then returned to Rachel. â€Å"Good luck,† he said. Then he left. A guard rapped on the trailer door, and it opened from within. A technician emerged and motioned for Rachel to enter. She followed him in. The inside of the PSC was dark and stuffy. In the bluish glow of the lone computer monitor, Rachel could make out racks of telephone gear, radios, and satellite telecommunications devices. She already felt claustrophobic. The air inside was bitter, like a basement in winter. â€Å"Sit here, please, Ms. Sexton.† The technician produced a rolling stool and positioned Rachel in front of a flat-screen monitor. He arranged a microphone in front of her and placed a bulky pair of AKG headphones on her head. Checking a logbook of encryption passwords, the technician typed a long series of keys on a nearby device. A timer materialized on the screen in front of Rachel. 00:60 SECONDS The technician gave a satisfied nod as the timer began to count down. â€Å"One minute until connection.† He turned and left, slamming the door behind him. Rachel could hear the bolt lock outside. Great. As she waited in the dark, watching the sixty-second clock slowly count down, she realized that this was the first moment of privacy she’d had since early that morning. She’d woken up today without the slightest inkling of what lay ahead. Extraterrestrial life. As of today, the most popular modern myth of all time was no longer a myth. Rachel was just now starting to sense how truly devastating this meteorite would be to her father’s campaign. Although NASA funding had no business being on a political par with abortion rights, welfare, and health care, her father had made it an issue. Now it was going to blow up in his face. Within hours, Americans would feel the thrill of a NASA triumph all over again. There would be teary-eyed dreamers. Slack-jawed scientists. Children’s imaginations running free. Issues of dollars and cents would fade away as petty, overshadowed by this monumental moment. The President would emerge like a phoenix, transforming himself into a hero, while in the midst of the celebration, the businesslike senator would suddenly appear small-minded, a penny-pinching Scrooge with no American sense of adventure. The computer beeped, and Rachel glanced up. 00:05 SECONDS The screen in front of her flickered suddenly, and a blurry image of the White House seal materialized on-screen. After a moment, the image dissolved into the face of President Herney. â€Å"Hello, Rachel,† he said, a mischievous glint in his eye. â€Å"I trust you’ve had an interesting afternoon?† 29 The office of Senator Sedgewick Sexton was located in the Philip A. Hart Senate Office Building on C Street to the northeast of the Capitol. The building was a neo-modern grid of white rectangles that critics claimed looked more like a prison than an office building. Many who worked there felt the same. On the third floor, Gabrielle Ashe’s long legs paced briskly back and forth in front of her computer terminal. On the screen was a new e-mail message. She was not sure what to make of it. The first two lines read: SEDGEWICK WAS IMPRESSIVE ON CNN. I HAVE MORE INFORMATION FOR YOU. Gabrielle had been receiving messages like this for the last couple of weeks. The return address was bogus, although she’d been able to track it to a â€Å"whitehouse.gov† domain. It seemed her mysterious informant was a White House insider, and whoever it was had become Gabrielle’s source for all kinds of valuable political information recently, including the news of a covert meeting between the NASA administrator and the President. Gabrielle had been leery of the e-mails at first, but when she checked out the tips, she was amazed to find the information consistently accurate and helpful-classified information on NASA overexpenditures, costly upcoming missions, data showing that NASA’s search for extraterrestrial life was grossly overfunded and pathetically unproductive, even internal opinion polls warning that NASA was the issue turning voters away from the President. To enhance her perceived value to the senator, Gabrielle had not informed him she was receiving unsolicited e-mail help from inside the White House. Instead, she simply passed the information to him as coming from â€Å"one of her sources.† Sexton was always appreciative and seemed to know better than to ask who her source was. She could tell he suspected Gabrielle was doing sexual favors. Troublingly, it didn’t seem to bother him in the least. Gabrielle stopped pacing and looked again at the newly arrived message. The connotations of all the e-mails were clear: Someone inside the White House wanted Senator Sexton to win this election and was helping him do it by aiding his attack against NASA. But who? And why? A rat from a sinking ship, Gabrielle decided. In Washington it was not at all uncommon for a White House employee, fearing his President was about to be ousted from office, to offer quiet favors to the apparent successor in hopes of securing power or another position after the changeover. It seemed someone smelled Sexton victory and was buying stock early. The message currently on Gabrielle’s screen made her nervous. It was like none other she had ever received. The first two lines didn’t bother her so much. It was the last two: EAST APPOINTMENT GATE, 4:30 P.M. COME ALONE. Her informant had never before asked to meet in person. Even so, Gabrielle would have expected a more subtle location for a face-to-face meeting. East Appointment Gate? Only one East Appointment Gate existed in Washington, as far as she knew. Outside the White House? Is this some kind of joke? Gabrielle knew she could not respond via e-mail; her messages were always bounced back as undeliverable. Her correspondent’s account was anonymous. Not surprising. How to cite Deception Point Page 27, Essay examples

There are many main causes of accidents; some accidents may be caused by general factors which may include poorly trained employees, inadequate property and equipment maintenance, weak equipment design and many more. Accidents may also be caused by direct causes such as impairment of the chemicals being used. Accidents may as well be caused by Indirect causes which may include conditions such as unsafe working conditions and unsafe acts performed by employees.

Lack of motivation and fatigue on the part of employees may also be considered as indirect causes of accidents. When employees are unmotivated or over fatigued they become careless in work which may lead to accidents/ (Eckhardt, B.) Accidents may be caused by several different factors. Which is why being able to understand what caused these accidents is exceptionally important. This is so that we could be able to prevent them from happening again in the future .There are several techniques in order to determine the main cause of an accident. One such method is the change analysis method. The main idea of change analysis is to study what changes in the work chain have caused the accident. The first step in change analysis is to be able to determine first what the main cause of the accident is. The next step is to find out what happened in the accident and compare it to what should really have happened. After this you should be able to identify the differences between the two and you could now evaluate these changes. After doing this, the last step would then be identifying the things that have been affected and those that have not been affected and identify the features or differences of these changes. After all this, make a list of all the probable causes of the accident and identify the most probable cause. (united states coast guard). Another Technique to determine the cause of an accident is by using the job safety analysis technique. This method is mainly used to study the different processes involved in performing a job. This technique could be used as well as to examine the safety as well as the potential health hazards involved in each job step. This technique is already widely used in many accident investigations worldwide. The process would involve first identifying the hazard that may have occurred in each step of a job. After doing this, the next step would be to try to suggest ways to prevent such hazards from happening again. If job safety analysis has been practiced before then one could try to review it and see if why the accident still happened. If no job safety analysis was made then it would be wise to create a new one for the job. (Maricopa County). One last technique that could be used in accident investigations is by applying the root cause analysis technique. Root cause analysis is a problem solving technique wherein the main goal is in being able to identify the main cause of a problem. When using root cause analysis in accident investigations, the entire chain of events that happened in the accident is studied in order to find the â€Å"root cause† of the accident. Usually the root causes of accidents are inadequacies in the safety system being used. Other usual factors that may be the root cause of accidents may include mental illness of employees, lack of skills and knowledge of the employees, as well as equipment malfunction and hazardous workplace environment. (12manage). As discussed earlier, the process of investigating accidents may involve identifying the cause of the accident as well as determining the damage cost caused by the accident. Several factors need to be considered when conducting accident investigations. First it is important that all accidents must be investigated without exceptions and accidents that may cause death or serious injury should be more thoroughly investigated than ordinary accidents. It is also important that accidents should be investigated immediately. It does not matter whether the accidents may be minor or major, all accidents should be answered with a quick response. Other factors that need to be investigated in accidents include factors like the identities of the injured, the place where the accident occurred, the time when the accident happened, the probable causes of the accident and most importantly ways on how to prevent a similar accident from happening again. The techniques in investigating these things would also differ depending on the nature of the accident as well as the damage the accident may have caused. This is why it is important to first determine the investigation’s scope. It is also important that a team be formed. Each investigator of the team should also be assigned with a task to perform. Some investigators would be assigned to investigate the production procedures, while others would be assigned to investigating the engineering of the equipment which caused the accident, etc. conducting a briefing to your investigative team to explain to them the facts of the accident is also important. Before taking on their assigned tasks, it is first important that they are aware about the accident like the description of the accident and the damage it had caused. (Utah University).   After the briefing, the investigative team should now start gathering facts. This would mean that they should start interviewing witnesses that may be around the accident when it occurred. When interviewing people, it is of utmost important that preliminary statements be gathered quickly. The location of each witness during the accident should also be charted. They should also hastily investigate the site of the accident before any changes to it happen. Pictures of the accident scene should also be taken or sketches of it be drawn, try to gather also all available reports. An example of accident photography is a technique that is often used in aircraft accidents. In aircraft accidents, it is important that all photographs are accurate and not hide any details of the scene of the accident. Photographs should include the accident itself as well as its surroundings and even the underneath of the aircraft. Pictures should also be taken immediately upon the arrival at the scene of the accident. In aircraft accidents details before extensive fire damage may be lost if pictures are not taken immediately. Among the first photos that need to be taken are those of the rescue operations like the rescuing of the occupants from the aircraft, as well as the medical treatment being given to the survivors of the accident. The purpose of this is to check if any human failure has caused the accident. Pictures of casualties should show the position of the body in relation to the wreckage. If faced with reporters be sure to not give out information that is unnecessary. All these techniques are not only applicable to aircraft accidents but also other accidents. (integrated publishing).
