1ABSTRACTThis report is prepared for the coursework/assignment on OSH Management System. I choose to discuss the main components of HIRARC, and develop HIRARC on changing a flat tire task. Hazard Identification, Risk Assessment and Risk Control, HIRARC has become extremely important in helping to ensure safety of the workplace or activities in daily life. This assignment illustrates HIRARC implementation for changing a flat tire. There are some activities done in identifying the hazard before analyse the risk using various resource. The impact of this project is to inflict awareness on the danger or hazard exist in the while changing a flat tire and the importance of practising safe work procedure in order to prevent the hazard from being realized. This assessment should be done periodically according to needs and not to be treated as a one-off exercise.The objective of this report is to write up on the methodology for identifying the hazards during changing a flat tire operation, assess and evaluate whether safety and health risks are tolerable or not and to suggest the right practicable control measures that can be applied for everyone when encounter this situation.At the later part of this report, the critical hazard will be discussed in details.

2INTRODUCTIONWith the development of science and technology, the cars have already become the important component in our daily life gradually. Cars make our life convenient and swift. Some people claim that the disadvantages of car are more than the advantages. I doubt whether the argument can bear much analysis. Since one century ago, the auto industry has developed at full speed worldwide, and has brought the enormous progresses to our life. For example the car is the most convenient tool of transportation. We can be on and off duty by car every day, we can go to travel by car on the vacation, we can utilize the cars to deal with some emergency too. The car plays an important role in our daily life. They make our rhythm of life faster and faster, make our business become more and more efficient. Cars basically made of components such as the engine, cooling system, charging system, ignition system, brakes, wheel alignment, dashboard gauges, air conditioner, electrical systems, fuel system, battery, starting system, etc.Tire plays an important role as any other components we can find on cars. Theres a lot tire manufacturers worldwide such as Michelin, Bridgestone, Goodyear, and Dunlop to name a few. Actually, a tire is an advanced engineering product made of a lot more than a rubber. Fibre, textile, and steel cord are just some of the components that go into the tires inner liner, body plies, bead assembly, belts, sidewalls and tread.

Millions of Malaysian hit the roads every day, drive to work or school, travelling to vacation spots and visiting family and friends. Increased traffic on the road, coupled with conditions like construction and excessive heat, leads to higher numbers of vehicle accidents, injuries, and fatalities. One of leading causes of these traffic accidents is tire failure. Following are the main causes of a flat tire or tire blowout: Puncture from sharp objects Failure or damage to the valve system Separation of the tire rubber from the rim due to collision with another object Excessive wear of the tire tread, which can cause tire explosions Improper tire pressure combined with extreme heat Manufacturer defectsA flat tire can cause a driver to lose control of the vehicle, possibly causing a catastrophic accident. Changing a tire on the side of the road can be just as dangerous. This is the topic which I will discuss on the other page.


The main objective for this assignment is to develop a HIRARC based on tasks that were optional. I choose to develop a HIRARC for Changing Flat Tire. I am thankful to this module lecturer, Mr. Ismandi Bin Junaidi for his willingness to help me in understanding the different phases of HIRARC. Not forgetting my classmates, IEDOSH Batch 5 for their cooperation in exchanging valuable information.

4METHODOLOGYHAZARDS IDENTIFICATION For a start, in order to identify hazard, I must have a clear definition of what is hazard. Hazard is a source or situation with a potential harm for human (injury or ill-health), damage to property, damage to environment or any combination of these. Before risk assessment can be made, I need to have a clear understanding or knowledge of the work carried out and also situation. In order to find the nature of hazards, I looked into these 5 contributors which could be the source.Man = Human behaviour, Unsafe acts, e.g. horseplayMachinery = Installation, layout and design of equipmentMaterials = Substances e.g. Cement dust, chemicalsMethods = Ways people carry out their workMedia = Workplace condition e.g. noise

RISK ASSESMENT/ EVALUATIONRisk is the chance of probability of harm actually being done. In the risk assessment and evaluation process, there are two factors that determine the final outcome which are likelihood and severity. The formula of rating the risk as follow:-RISK = SEVERITY x LIKELIHOODLikelihood is the frequency or how likely is the hazardous event/ situation will occur. Whereas, severity is the degree of injury, damage to property or environment. The most common question is what might be the severity of a hazardous event or situation? Numbers are given to show the quantity of each likelihood and severity. Risk index or the level of risk can be obtained through multiplication of the number of likelihood and also the number of severity. (Refer table A, B, C, D)Table A (Severity Rating)Severity RatingConsequences

1First aid / near injuries

2Minor injuries(Less than or 4 days MC)

3Major Injuries(More than 4 days MC)


Table B (Likelihood Rating)Likelihood RatingLikelihood of Occurring

1Once in a year

2Once in 6 months

3Once a month

4Once a week

Table C (Risk Rating) Risk RatingLevel of RiskAction to Control
