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?

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.

Energy Sources

Gravity

Motion

Mechanical

Electrical

Pressure

Temperature

Chemical

Biological

Radiation

Sound

© Chevron 2005 6

The force caused by the attraction of all other masses to the mass of the earth.

Examples: a falling object, a collapsing roof, a body tripping or falling

Gravity

© Chevron 2005 7

The change in position of objects or substances.

Examples: vehicle, vessel or equipment movement, flowing water, wind, body positioning: lifting, straining, or bending

Motion

© Chevron 2005 8

Mechanical Energy

The energy of the components of a mechanical system, i.e. rotation, vibration, motion, etc. within otherwise stationary piece of equipment/machinery.

Examples: rotating equipment, compressed springs, drive belts, conveyors, motors

© Chevron 2005 9

The presence and flow of an electric charge.

Examples: power line, transformers, static charge, lightning, energized equipment, wiring, batteries

Electrical

© Chevron 2005 10

Pressure

Energy applied by a liquid or gas which has been compressed or is under a vacuum.

Examples: pressure piping, compressed gas cylinders, control lines, vessels, tanks, hoses, pneumatic and hydraulic equipment

© Chevron 2005 12

Temperature

The measurement of differences in the thermal energy of objects or the environment, which the human body senses as either heat or cold.

Examples: open flame and ignition sources, hot or cold surface, liquids or gases, hot work, friction, general environmental conditions, steam, extreme and changing weather conditions

© Chevron 2005 13

Chemical Energy

The energy present in chemicals that inherently, or through reaction, has the potential to create a physical or health hazards to people, equipment, or the environment.

Examples: flammable vapors, reactive hazards, carcinogens or other toxic compounds, corrosives, pyrophorics, combustibles, inert gas, welding fumes, dusts

© Chevron 2005 14

Living organisms that can present a hazard.

Examples: animals, bacteria, viruses, insects, blood-borne pathogens, improperly handled food, contaminated water

Biological Energy

© Chevron 2005 15

Radiation

The energy emitted from radioactive elements, or sources, and naturally occurring radioactive materials.

Examples: lighting issues, welding arc, X-rays, solar rays, microwaves, naturally occurring radioactive material (NORM) scale, or other non-ionizing sources

© Chevron 2005 16

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
