Lockout Tagout Training
Lockout Tagout Training enables electrical engineers to implement OSHA-compliant energy isolation, NFPA 70E practices, arc flash hazard controls, de-energization procedures, and verified zero energy state before maintenance, troubleshooting, or commissioning tasks.
Understanding Lockout Tagout Training for Compliance with NFPA 70E
Effective lockout tagout training is more than just a regulatory requirement—it's a critical component of a robust safety culture. Under OSHA 1910.147(c)(7), employers are responsible for ensuring that employees are trained to understand and safely apply energy control procedures. For safety managers and EHS professionals, this means developing a structured, role-specific educational program that evolves with your equipment, processes, and workforce.…

What is Electrical Arcing?
Electrical arcing is not merely a visible discharge. It is a structural failure of electrical integrity that signals insulation breakdown, connection instability, or contamination severe enough to let current abandon its intended path. When it occurs, equipment damage is already underway, and the probability of escalation into arc flash conditions increases rapidly.
Electrical arcing occurs when electrical current jumps through air between conductors or to ground, releasing extreme heat, intense light, and localized mechanical force. Unlike a brief spark, an arc sustains itself once air becomes ionized, allowing continuous current flow that erodes metal, carbonizes insulation, and destabilizes protective coordination.…

Arc Flash Blast Explosion – NFPA 70E Pressure and Overpressure
An arc flash blast explosion releases intense heat and pressure within milliseconds, hurling molten metal and gas with deadly force. NFPA 70E safety training and proper PPE are essential to prevent severe burns, equipment damage, and hearing injuries.
Understanding Arc Flash, Blast, and Explosion in Electrical Safety
Unlike a simple short circuit, an arc blast releases both thermal and mechanical energy. The rapid rise in pressure—sometimes hundreds of pounds per square inch—can rupture switchgear doors and ignite fires in surrounding equipment. For a broader discussion of electrical explosion hazards, see our Electrical Explosion page.

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.…
