HAZWOPER Safety and Health Program

Standard Operating Procedures and Practices

Standard Operating Procedures (SOPs) are important to make sure everyone knows how to perform the correct procedures. The SOPs below should be included in all safety and health plans.

Hazard Control Strategies

How will employers control hazards and employee exposure at the site? Employers can control hazards using the hierarchy of controls approach, with the most effective control used to reduce or eliminate the hazard.

The order of hierarchy of controls, from most to least effective is: elimination, substitution, engineering controls, barriers, enclosures, administrative controls, safe-work practices, and personal protective equipment.

If feasible, the employer must institute engineering controls and work practices to help reduce and maintain employee exposure to or below permissible exposure limits.

  • Examples of suitable and feasible engineering controls include the use of pressurized cabs or control booths on equipment and/or remotely operated material handling equipment.
  • Examples of safe work practices include removing all non-essential employees from potential exposure while opening drums, wetting down dusty operations, and placing employees upwind of potential hazards.
