Hazard Identification
To prevent incidents, workers must recognize and effectively identify the hazards associated with the tasks they perform.
By focusing on the principles of hazard recognition we are not asking workers to memorize a list of thousands of possible hazards, but rather to understand broad categories of hazards.

A condition or action that has the potential for an unplanned release of, or unwanted contact with an energy source that may result in harm or injury to people, property or the environment.
What is a Hazard?
![Page 4: HazId CBT 2009](https://reader035.vdocuments.us/reader035/viewer/2022081717/542e4f8e219acdf5478b480e/html5/thumbnails/4.jpg)

Hazard Identification Tool
This tool was developed to help us identify workplace hazards.
The tool utilizes an energy source model to key users to the potential hazards present in the workplace.
Each energy source should be evaluated for its presence and the potential for related hazards.
Once the hazards are identified, they should be mitigated to prevent an incident from occurring.
We will now work through each of the energy sources along with some examples.

Sound Energy
Sound is produced when a force causes an object or substance to vibrate––the energy is transferred through the substance in waves.
Examples: impact noise, vibration, high-pressure relief, equipment noise
