To conduct a Job Safety Analysis using the template, You have to first breakup the Job into different tasks. Once Tasks have been fragmented, You could use these tasks to fill in the analysis sheet.
Now you have to pick each individual task and find out as much as possible hazards associated with it. Once uncontrolled hazards identified, next step is to find out Risk Rating associated with a hazard.

When did regulations become more important than safety?


There are a huge regulations and guidelines about Health Safety and Environment (HSE), some of guidelines are international and very helpful, but sometimes, they are not according to country’s regulations, occasionally, the guidelines are better than regulations. So, why we should follow the regulations instead the guidelines?

                In my country, often the regulations are not complete when they are compared to international guideline, but we still need follow them. Thus if your country does not have this problem, this text might not interesting you even though you liked the title.

                When I began study about HSE area, the first thing I had learned was the most important thing is the work force’s health, and to reach that goal, we must use own intelligent, experience and patience but our allies will be the regulation. However, I had begun to work and face that it is not a complete true, our true work, it about helps company produce without injury or kill its work force.

                Additionally I had found out the guidelines and how it can turn my work a little more easy. Consequently, I realized that we who work in HSE area, must need follow the regulations until it became poor or weak (because this is the law) but never limited only this, we must also use the guidelines as a support, to help us to reach the big goal (helps company produce without injury or kill its work force).

                Therefore, I have attached this text one of the guidelines which still helps me in my work, I really hope this helps you as well as helped me.

Identification for mixture chemical ?
albertsu88 wrote: Pure chemical has its MSDS but mixture is not. What kind of guide can be used to identify it? 

It is not so simple, but there is a solution. We can use a device, which able to measure a Lower Explode Limit (LEL), this equipment usually can measure three chemical gas, and they are: CO2, H2S and Oxygen, but it also shows LEL (in percent). As a result, it is mostly used for Confined Space, though, we can use it for other kind of work that there is a possibility to have one type (or more) of gas.

For example, if you are working and suddenly this device begins to alarm, it is means that the atmosphere which you are working, has reached to LEL level. In other words, it is mean that there is a large risk of explosion. Then, you must stop the work and follow the company’s procedure for this situation.


I really hope that it has helped you.

Best regards
