Workers who do servicing and maintenance of machines or equipment can be exposed to hazards during the unexpected startup or release of stored energy from electrical, mechanical, hydraulic, pneumatic, chemical, thermal, or other sources in machines and equipment. Hazards like these can lead to serious injuries such as the following:

  • Electrocution.
  • Burns.
  • Crushing or smashed body parts.
  • Lacerations.
  • Amputations.

Fortunately, there are specific practices and procedures called Lockout/Tagout (LOTO) that address these hazards and protect workers from being seriously injured.

Information provided in this topic page can help employers and employees identify and evaluate existing or unforeseen safety and health hazards and provide resources to help with training, prevention methods, and the development and implementation of a required written safety and health accident prevention program (APP).
