Asbestos is not absorbed through the skin.Note: Improper or inadequate maintenance can result in increased opening time of the overcurrent protective device, thus increasing the incident energy.
The closer you approach an exposed, energized conductor or circuit part, the greater the chance of an inadvertent contact and the greater the injury that an arc flash event will cause. Incident Energy Method is used, and every label has a different Arc Flash Boundary.
Use this number as a guide in the future when racking the circuit breaker back in.
