122 Introduction to Hazard Controls
Skip to main content

Environment

Are there areas in your workplace that are too bright, dark, hot, cold, dusty, dirty, messy, wet, etc.? Is it too noisy, or are dangerous gases, vapors, liquids, fumes, etc., present? Do you see short people working at workstations designed for tall people? Such factors all contribute to an unsafe environment. You can bet a messy workplace is NOT a safe workplace!

An noisy work environment can cause hearing damage.

Equipment

Hazardous equipment includes machinery and tools.

  • Hazardous equipment should be properly guarded so that it's virtually impossible for a worker to be placed in a danger zone around moving parts that could cause injury or death. A preventive maintenance program should be in place to make sure equipment operates properly. A corrective maintenance program is needed to make sure equipment that is broken, causing a safety hazard, is fixed immediately.
  • Tools need to be in good working order, properly repaired, and used for their intended purpose only. Any maintenance person will tell you that an accident can easily occur if tools are not used correctly. Tools that are used while broken are also very dangerous.
Heavy equipment is always dangerous.

Noise Exposure

Many work places are inherently noisy and potentially hazardous to employees. Continuous noise and instantaneous noise bursts can damage the hearing of employees. A hearing conservation program should be established if you think noise levels are a potential threat to the health of your employees. OSHA consultants, your insurer, or a private consultant are all available to help you determine noise levels in the workplace.

Electric Shock

Electricity travels in closed circuits, normally through a conductor. Shock occurs when the body becomes part of the electric circuit. The current must enter the body at one point and leave at another. Shock normally occurs in one of three ways. The person must come in contact with:

  • both wires of an electric circuit,
  • one wire of an energized circuit and the ground, or
  • a metallic part that has become "hot" by being in contact with an energized wire or conductor, while the person is also in contact with the ground.

Illumination

It's important to make sure illumination is adequate for the job being performed. Too much direct or indirect glare can, over time, cause eye strain. Too little light can result in an injury.
