Hazard I dent ificat ion

To prevent incidents, workers m ust recognize and

effect ively ident ify the hazards associated with the

tasks they perform .

By focusing on the principles of hazard recognit ion

we are not asking workers to m em orize a list of

thousands of possible hazards, but rather to

understand broad categories of hazards.

A condit ion or act ion that has the potent ial for an

unplanned release of, or unw anted contact with an

energy source that m ay result in harm or injury to

people, property or the environm ent .

W hat is a Hazard?

Hazard I dent ificat ion Tool

This tool was developed to help us ident ify workplace

hazards.

The tool ut ilizes an energy source m odel to key users

to the potent ial hazards present in the workplace.

Each energy source should be evaluated for its

presence and the potent ial for related hazards.

Once the hazards are ident ified, they should be

m it igated to prevent an incident from occurr ing.

We will now work through each of the energy sources

along with som e exam ples.
