1 Introduction
This is a technique report that outlines the findings and recommendations of a safety inspection within the School of AMME. All of potential hazards and other issues performing on a variety of areas in AMME, R.F HALLIDAY LABORATORY and MECHAINICAL TESTING LABORATORY, which may not satisfy the University’s WHS Policy or the NSW WHS legislation, have been listed in the following parts.
The recommended solutions and methods that will address these issues to reduce risk as well as decrease the potential hazards based on University’s WHS Policy and NSW WHS Legislation are also included in this technique report.
The safety management for school of AMME especially for the R.F HALLIDAY LABORATORY and MECHAINICAL TESTING LABORATORY must obey University’s WHS Policy and NSW WHS Legislation on safe manufacturing and construction. Students’ and all the other operators’ safety and healthy shall be protected during building up the lab. The principle “safety and prevention first” are insisted during inspection. Some of the safety responsible system and equipment safety shall be improved.
It is necessary to talk about the potential hazards in mechanical laboratory rooms to protect health and prevent possible incidents.

2 Hazard Identification and Explanation
In this chapter, it will introduce the potential hazards that have been inspected in mechanical lab rooms. It firstly starts with the hazards identification as well as explanation in R.F HALLIDAY LABORATORY room, and then it comes to the second room of MECHAINICAL TESTING LABORATORY. Actually, the hazards involved are all based on WHS policy pictures inspected in the lab room.
2.1 R.F HALLIDAY LABORATORY
In this laboratory room, there are some mechanical machines and operating elements lying on almost everywhere. Furthermore, there are several computers with measurement machines in the middle of the room. In this part, it will introduce some potential hazards in this lab room.
2.1.1 Stumble

The large machine lying on the passageway may lead staff stumble and falling down. Even worse, they may strike the machine arm and get hurt.
2.1.2 Objects falling down

As the picture above shows, it is extremely possible that the elements could fall down from the table when staffs pass by and are hurt by falling components unconsciously, which may even lead to physical injured.
2.1.3 Potential fire hazard

Fire safety refers to precautions that are taken to prevent or reduce the likelihood of a fire that may result in death, injury or property damage.
From the figure above we can find that the petrol drum located at the corner without any warning or attention signal. When walking around it, the smell of petrol can be smelt obviously, which means the concentration of gas petrol is at high level. When doing the mechanical testing experiment, the spark of fire is unavoidable. Then when the concentration reaches explosion level and meet fire, there will exist fire and explosion incident.
2.1.4 Uncontrolled escape

From the figure above we can find this is a wheel of an operation desk. The wheels of this operation desk are not attached with breaking desk. Most of the mechanical experiment will make the operation desk vibrate, some cutting machine will produce a huge force, which means when operating the machines, uncontrolled escape is easy to occur.
2.1.5 Falling down from high place

From the figure above we can find this is a ladder with gradient about 90 degrees connecting the ground floor and second floor. Around the ladder, there is no warning or attention signal to make people notice the potential falling incident. What’s even worse, there is no any kind of protecting devices that will make the risk of falling increase.
2.1.6 Unfixed things releasing

From the figure above we can find that there are several huge boxes on top of cabinet. All of these boxes are unfixed, some of which are even out of the cover range of cabinet. Similar with uncontrolled escape, when doing some testing, there usually have vibrate. Some of strong vibrate will even cause shake of floor and may cause the unfixed things releasing from height.
2.1.7 Electric Shock

Electric shock is the physiological reaction or injury caused by electric current passing through the body of human.
From the figure above we can find that the power sockets located just near the sink and water taps. When operators try to use the water taps, the water splashed will easily get in touch with the power socket. Then the electric current will pass through the human’s body and cause the electrical shock.
2.1.8 Easily access to machine

As shown above, keeping the key always inserted will bring a hazard that easily touch can start the machine, even unconsciously. This frequently activation may break the machine and cause worse effect such as fire and injury if without notice.
2.1.9 Physical injury

Physical injuries include those caused by mechanical trauma, heat and cold, electrical discharges, changes in pressure, and radiation.
From this picture above, it is fairly possible that the staff would be injured by this large-scale mechanical arm when operating it with fatigued. Also, there is no warning or attention signal around this machine to notice people with this hazard.
2.2 MECHAINICAL TESTING LABORATORY
In this laboratory room, there are some mechanical testing pods containing some operating machines in it. Furthermore, the testing pods are individual from each other that are separated by some boards. In this part, it will introduce some potential hazards in this lab room.

2.2.1 Inrush of water

From the figure above we can find that there is a water tap hidden behind large-scale equipment. There is no signal telling people about the location of this water tap. When moving or operating the equipment, it is easy to destroy this water tap and cause inrush of water. From another aspect, this water tap located at coveter leading to unpractical to maintain and check periodic, which also increases the risk of inrush water incident.
2.2.2 Physical injury

Physical injuries include those caused by mechanical trauma, heat and cold, electrical discharges, changes in pressure, and radiation.
From this picture above we can observe that people are easily injured by this machine with incorrectly operating, for example if staff put fingers under the blades of the machine the fingers would be cut as a result.

2.2.3 Uncontrolled escape

From the figure above we can find this is a wheel of an operation desk. The wheels of this operation desk are not attached with breaking desk. Most of the mechanical experiment will make the operation desk vibrate, some cutting machine will produce a huge force, which means when operating the machines, uncontrolled escape is easy to occur.

2.2.4 Potential fire hazard

Fire safety refers to precautions that are taken to prevent or reduce the likelihood of a fire that may result in death, injury or property damage.
From the figure above we can find that the petrol drum located at the corner without any warning or attention signal. When walking around it, the smell of petrol can be smelt obviously, which means the concentration of gas petrol is at high level. When doing the mechanical testing experiment, the spark of fire is unavoidable. Then when the concentration reaches explosion level and meet fire, there will exist fire and explosion incident.

2.2.5 Unfixed things releasing

From this picture above we can see that the lager-scale machine with no protection measures will easily fall down from the shelf in height. Since with no warning or attention signal nearby, staffs may be physically hurt by this unfixed machine or even to death.
2.2.6 Electrocution

Electrocution is death caused by electric shock, either accidental or deliberate. Electric shock is the physiological reaction or injury caused by electric current passing through the body of human.
From the picture above, the electric switch box has not been locked, which means someone come to touch it leading to an easy access to high voltage electricity with the terrible result of electrocution. On the other hand, although there is a warning signal on it, it is too small to recognize and not marked.

2.2.7 Metal beams falling down

From this picture we can see that there is a large number of metal beams filled in this lab room on the roof side. It is obviously that the metal beams are in a simple construction, which means it is quite probably that the construction of metal beams would be broken, and as a result leading to physical injured or even death.
2.2.8 Objectives falling down

From this picture above, we can see that a great deal of elements have been placed on the desk including some metal components, a huge box of material, a large amount of paper material with high weight and so on. What is worse, most of them are just at the edge side of the desk, which means it increased the probability of these elements to fall down from desk. And since there is no warning signal nearby, as a result people pass by with no attention may be physically injured.
2.2.9 Machines unstable

In the picture above, this machine is too high and center of gravity is a little bit high for the whole machine, which means it is not stable when being used. In this condition, when people operate with it, it is possible that staff would be injured by falling down of this machine due to instability.
2.2.10 Break machine

The photo above shows the incomplete electrical machine lying near the laboratory door. Tools, instruments and even water can easily drop into the inner machine from the black hole, which may further cause machine broken due to difficult clear.

Assignment of Income Doctrine

...ACC 616 Prof. Robert Simpson Student name: On the back Assignment 1: Explain Assignment of Income Doctrine The "assignment of income" doctrine states that income is taxed to the one who actually earns it. That means a taxpayer cannot avoid tax liability by assigning his income to another party or entity. Therefore, to be able to shift income to someone else, that one must actually earn the income. This doctrine aims to against the tax evasion when the taxpayer tries to deflect income to another party. First, starting from the term “earning”, earnings can occur either through the direct efforts of the taxpayer or the taxpayer’s ownership of an asset that generates income. Based on that understanding about earning, there are 2 ways to shifting income from one to another: the transferee must really work to earn that income or share the ownership of an asset that creates income. For example, if you are an owner of a business and you want to shift one part of your income to your family member such as your son, you need to hire your son to work for your company and give him the pay rate that is appropriate with his job. And the other way is to share your investment income with him, same meaning with sharing your ownership with him. The assignment of income applies the “tree and fruit” metaphor, in which the fruits cannot be attributed to a different tree from that on which they grew. If you want to avoid the tax liability on the fruit from the tree, you must prove that the...

...Janell Taylor 10/23/12 Implicit Test I found the test to be very interesting and I don’t like timed tests because I need time to think about my answer to be sure and confident about my choice. I don’t agree with the results because they said I made too many errors and I don’t understand that because that was just one part where I was making too many errors. It has helped me out in those areas of different topics, but I just wish I had more time. I guess I would say that the answers wasn’t valid enough for me because it didn’t really give me a score because I made too many errors, so I don’t agree with that too much. I believe prejudice is difficult to measure because I don’t agree with it and don’t like the fact that it’s very big and can get worse if we don’t come together to get in one accord to help each other and make the world better to live in dealing with different people and feelings. I think measuring prejudice can be a tough thing to deal with and handle because of the many people that are prejudice, which are hurting and harming many situations and people that’s trying to make it while being equal to everyone regardless of what.

Mat222 Week 1 Assignment.

...Solving Proportions MAT222 Week 1 Assignment September 22, 2014 Solving Proportions Solving for a proportion can be used within numerous real-world problems, such as finding the population of an area. Conservationists are able to predict the population of bear’s in their area by comparing information collected from two experiments. In this problem, 50 bears in Keweenaw Peninsula were tagged and released so conservationists could estimate the bear population. One year later, the conservationist took random samples of 100 bears from the same area, proportions are able to be used in order to determine Keweenaw Peninsula’s bear population. “To estimate the size of the bear population on the Keweenaw Peninsula, conservationists captured, tagged, and released 50 bears. One year later, a random sample of 100 bears included only 2 tagged bears. What is the conservationist’s estimate of the size of the bear population (Dugolpolski, 2012)?” In order to figure the estimated population, some variables need to first be defined and explain the rules for solving proportions. The ratio of originally tagged bears to the entire population is (50/x). The ratio of recaptured tagged bears to the sample size is (2/100). 50x=2100 is how the proportion is set up and is now ready to be solved. Cross multiplication is necessary for this problem. The extremes are (100) and (50). The means are (x) and (2). 100(50)=2x New equation, and now solve for (x). 50002=2x2 Divide both...

...conservationist’s estimate of the size of the bear population? You will notice while reading question #56 on page 437, we are to assume that the ratio of originally tagged bears to the whole population is equal to the ratio of recaptured tagged bears to the size of the sample. The ratio of originally tagged bears to the whole population is 50X The ration of recaptured tagged bears to the sample size is 2100 50X=2100 This is the proportion set up and ready to solve. I will cross multiply setting the extremes equal to the means. 10050=2x 100and 50 are the extremes, while X and 2 are the means. 50002=2x2 Divide both sides by 2 X = 2500 The bear population on the Keweenaw Peninsula is around 2500 bears. The second problem for assignment one week one I am asked to solve the below equation for y. The first thing I notice is that a single fraction (ratio) on both sides of the equal sign so basically it is a proportion which can be solved by cross multiplying the extremes and the means. y-1x+3=-34 Is the equation I am asked to solve. 3y-1=-3x-4 The result of the cross multiplying. 3y-3=-3x+12 Distribute 3 on the left side and -3 on the right. 3y-3+3=-3x+12+3 Subtract 3 from both sides. 3y=-3x+15 3y3=-3x3+153 Divide both sides by 3 y=-x+5 This is a linear equation in the form of y=mx+b. This equation is in its simplest form. I like how we can take just a couple of numbers from a word equation and put it in an order that will help us solve many estimates...

Pt1420 Unit 3 Assignment

...6.1) Comparison of three numbers Problem is of comparison of values among three values , a very simple problem. Here, the decision making process is done based on the value of the parameters a,b and c. The data types of all these variables are interger. 6.2) Binary search A binary search locates the position of an item in a sorted array. Binary search works by comparing an input value to the middle element of the array. The comparison determines whether the element equals the input, less than the input or greater. When the element being compared to equals the input the search stops and typically returns the position of the element. If the element is not equal to the input then a comparison is made to determine whether the input is less than or greater than the element. Depending on which it is the algorithm then starts over but only searching the top or bottom subset of the array's elements. If the input is not located within the array the algorithm will usually output a unique value indicating this. Binary search algorithms typically halve the number of items to check with each successive iteration, thus locating the given item (or determining its absence) in logarithmic time. A binary search is a dichotomic divide and conquer search algorithm. 6.3) Quadratic problem In Quadratic equation solver problem(called the procedure under test) is chosen. This procedure has three predicates involving both linear and non-linear functions of the input variables. In this there are three...

...11108944 Name: ASHWINI KUMAR Roll No. : RE3R02B32 PART- A 1. Ans :- (a) unary and ternary operator Unary operator:- It pecedes an operand . The operand (the value on which the operator operates ) of the unary operator must have arithmetic or pointer type and the result is the value of the argument.

Prg/211 Calorie Count Tool

...Team B Calorie Count Tool PRG/211 May 5, 2014 Team B Calorie Count Tool PROBLEM STATEMENT Team B was asked to develop a program which would calculate the user’s daily intake of calories and measure those calories against the overall calories expended. The core purpose of this program will do two primary functions. First, it will record the user intake of calories as acquired through meals throughout the day. Second, the user will record caloric output associated with physical activity. This information will be calculated together to determine the caloric surplus or deficit for the user. In order for the program to execute accurately, and provide customized results, the user will be required to input personal data to include gender, age, weight, and height. This additional information is essential to determine the user’s default caloric burn rate, otherwise known as the basal metabolic rate (BMR). The BMR and the calories burned as a result of physical activity will be calculated against the intake of calories to determine the overall success for the user. As the program is executed it must: * Record user name, age, height, weight to enable more accurate calculations * Record the users specific caloric values entered for each meal * Record the user activity and caloric burn values for that activity * Calculate the basal metabolic rate (BMR) for the individual * Subtotal the total caloric values for the day * Combine the physical activity and...

Andy Owes Bill a Debt.

...Law Written Assignment 3 Case Study 1 Parks, a 7-foot, 265-pound center for the San Diego Slick, objected when his contract was assigned from the ABC Corporation to the XYZ Corporation, the team’s new owner. The change of owners did not cause a change in the composition of the team although a new coach was hired. Parks’s compensation and his responsibilities remained the same. Was this contract assignable? Facts of the Case: 1) Parks contract was assigned from the ABC Corporation to XYZ Corporation. 2) Parks compensation and his responsibilities remained the same. Issues: 1) The reason why we are in court today is to identify if Park’s contract was assignable. Rules of the Law: 1) Personal Service Contract – The parties agree that a personal service contract may be assigned. This allows the trade of an athlete from one team to another team. 2) Notice of Assignment – Assignee is under a duty to notify the obligor that the assignment has been made and performance must be rendered to the assignee. 3) Anti-Assignment Clause – Prohibits the assignment of rights under the contract. 4) Approval Clause – requires that the obligor approves any assignment of contract. Analysis & Conclusion: Since we do not have all the facts we can assume the following: 1) Parks contract did include the Personal service contract. 2) Notice of assignment was made by XYZ Corporation. 3) Parks contract did NOT include Anti-Assignment Clause. ...

To do this I will first, briefly describe the event, supporting my outline with relevant information. I will then explore the event, and discuss why it is important and how it relates to the learning outcome. I will also be discussing why materials such as law and guidelines say this is important. I will then proceed to analyse the incident by breaking it down and picking out the main features of the experience, discussing why they are important, whilst linking the main points together. I will attempt to think about opposing arguments to what I have explored, and discuss the advantages and disadvantages of the arguments. Finally I will be using SMART goals, to create an action plan for future development. Explain incident with evidence Whilst on a shift, we had an elderly patient arrive on the ward.

Misconceptions of Algebra

...Diagnostic Algebra Assessment Definitions Categories Equality Symbol Misconception Graphing Misconception Definition Concept of a Variable Misconception Equality Symbol Misconception As algebra teachers, we all know how frustrating it can be to teach a particular concept and to have a percentage of our students not get it. We try different approaches and activities but to no avail. These students just do not seem to grasp the concept. Often, we blame the students for not trying hard enough. Worse yet, others blame us for not teaching students well enough. Students often learn the equality symbol misconception when they begin learning mathematics. Rather than understanding that the equal sign indicates equivalence between the expressions on the left side and the right side of an equation, students interpret the equal sign as meaning “do something” or the sign before the answer. This problem is exacerbated by many adults solving problems in the following way: 5 × 4 + 3 = ? 5 × 4 = 20 + 3 = 23 Students may also have difficulty understanding statements like 7 = 3 + 4 or 5 = 5, since these do not involve a problem on the left and an answer on the right. Falkner presented the following problem to 6th grade classes: 8 + 4 = [] + 5 All 145 students gave the answer of 12 or 17. It can be assumed that students got 12 since 8 + 4 = 12. The 17 may be from those who continued the problem: 12 + 5 = 17. Students with this misconception may also have difficulty with the idea that adding...

Book Report

...Selection statements Selection is used to select which statements are to be performed next based on a condition being true or false. Relational expressions In the solution of many problems, different actions must be taken depending on the value of the data. The if statement in C I used to implement such s decision structure in its simplest form – that of selecting a statement to be executed only if a condition is satisfied. Syntax: if(condtion) statement executed if condition is true When an executing program encounters the if statement, the condition is evaluated to determine its numerical value, which is then interpreted as either true or false. If the condition evaluates to any non-0 value (positive or negative), the condition is considered as a “true” condition and the statement following the if is executed; otherwise this statement is not executed. Relational Operators In C Relational operator | Meaning | Example | < | Less than | age < 30 | > | Greater than | height > 6.2 | <= | Less than or equal to | taxable <= 200000 | >= | Greater than or equal to | temp >= 98.6 | == | Equal to | grade == 100 | != | Not equal to | number !=250 | In creating relational expressions, the relational operators must be typed exactly as given in the above table. Thus, although the following relational expressions are all valid: age > 40 length <= 50 temp >= 98.6 3 < 4 flag == done day != 5 The following are invalid: length =< 50 ...
