Tip of the Week No. 277 - 03/22/10 - Static Electricity

Static electricity build-up and potential discharge create a spark in mines, refineries and similar sites establishes the need for grounding and minimzing frictional static build-up caused by lines rubbing.

Spark discharge from sudden contact between two metal surfaces is conceivable with fall arrest equipment use.

Plastic, grounded shells for fall arrest equipment and their synthetic lines, such as a retracting lifeline, should provide protection against exterior collisions.
