Hierarchy of controls
Occupational Health and Safety Organization (OSHA) and the National Fire Protection
Association (NFPA) recommend the system of Hierarchy of Controls to minimize
or eliminate exposure to occupational hazards. OSHA and NFPA are United States
organizations but the Hierarchy of Controls concept is relevant worldwide.
Elimination/substitution—removes a hazard all together or controls a hazard
by substituting something in its place that would be non-hazardous or less
hazardous.
Engineering controls—physical changes or modications designed
to eliminate or reduce hazardous exposure to equipment or a work
environment. This is the preferred method for eliminating and reducing
workplace hazards.
Safe work practice controls—safe work practices are designed
to change the way a job is performed to remove the employee
from exposure to the workplace hazard.
Administrative Controls—changes to include additional
backup workers, breaks and the rotation of workers to
reduce exposure to work hazards.
Personal Protective Equipment—protective
equipment or clothing worn by employees to reduce
injuries or exposure to hazardous or toxic substances.
The arc flash itself can achieve
temperatures in excess of 35,000 °F.

5 to 10 arc flash explosions occur
every day in the US.

Approximately 2,000 workers will
be admitted to hospital burn units this
year due to thermal burns from arc
flash or arc blast accidents.
