Arc Flash
Is arc flash analysis required by OSHA?
OSHA does not explicitly require arc flash analysis, but mandates hazard assessments under the General Duty Clause. NFPA 70E provides the standard method for hazard evaluation, PPE selection, and compliance with electrical safety rules.
Is Arc Flash Analysis Required by OSHA?
Employers must assess electrical hazards and provide appropriate personal protective equipment (PPE), making arc flash analysis a critical component of OSHA compliance. Our Arc Flash Hazard Analysis article explains how arc flash hazard analyses are utilized to establish safety boundaries, ensuring that workers maintain a safe distance from energized equipment to prevent injuries.

How Often Should You Inspect an Extension Cord?
Inspect extension cords before each use and after any event that could cause damage, such as rough handling, moisture exposure, or heavy electrical loads.
In practice, this means inspecting the cord each time it is picked up to ensure insulation is intact, plugs are secure, and there are no signs of overheating that could lead to shock or fire.
In most workplaces, extension cords are treated as minor accessories, pulled from a bin when power is needed and returned when the task is finished. That familiarity works against them. Cords are stepped on, pinched under doors, rolled over by carts,…

Understanding Electrical Safety Precautions for Compliance with NFPA 70E
One day, you might find yourself face-to-face with an electrical hazard. When and if that day comes, you want to be fully prepared. Now, you can say to yourself, "Electrical hazards can never happen to me," but just remember, those who have experienced an electrical hazard had doubts, too. Ask them now what they think—if they're still alive.…

ATPV - Arc Thermal Performance Value
ATPV defines how much arc flash incident energy arc-rated clothing can withstand before burn injury is likely. Measured in cal/cm², it guides PPE selection, arc flash risk assessment, and compliance with NFPA 70E and CSA Z462 standards.
ATPV, or Arc Thermal Performance Value, is a practical safety rating used to describe how well arc-rated clothing protects workers during an arc flash event. Rather than being an abstract laboratory number, it represents a real-world threshold where heat exposure becomes likely to cause injury. Understanding ATPV helps electricians, engineers, and safety managers make informed decisions about personal protective equipment and energized work.…
