663 HAZWOPER for General Site Workers IV
Skip to main content

Controlled and Uncontrolled Releases

Controlled Releases

It's important to remember that the Hazard Communication Standard (HCS) only covers response to incidental hazardous substance spills that:

  • are controllable,
  • are limited in quantity, exposure potential and toxicity
  • present only minor safety and health hazards to the immediate work area,
  • can be easily cleaned up by employees, and
  • do not have the potential for becoming an emergency.

Training for responding to incidental spills is covered under the Hazard Communication Standard (HCS) and includes spill cleanup procedures and the use of appropriate PPE.

Uncontrolled Releases

OSHA's HAZWOPER standard and its training requirements apply to efforts that are "HAZWOPER emergency responses" and hazardous waste site cleanups. Remember, training required for emergency response workers is quite different than that required for hazardous waste site workers. See OSHA's Emergency Preparedness and Response page.
