A personal fall protection arrest system (PFAS) is comprised of three vital components: an anchorage, body wear (full-body harnesses), and a connecting device (a shock-absorbing lanyard or self-retracting lifeline). The safety of at-height workers depends on these three components, and each one must be in place and used properly to provide maximum worker protection.
When discussing fall protection, anchorage connectors and full body harnesses receive a lot of attention. We don’t always stop to think about connecting devices like self-retracting lifelines or shock-absorbing lanyards, and yet these are the two components that bear the greatest forces during a fall.

Infrared safety: using thermal technologies to protect workers

BY DOUG BARRY, FLIR Systems

Disconnect switches, elbow connectors, cutouts, lightning arrestors, oil-filled circuit breakers, and other electrical components tend to heat up before they fail. The ability to detect overheating on such equipment long before it becomes critical is essential for preventing costly unplanned outages and for protecting workers from exposure to potential arc flashes and faults. The experienced and well-trained know it’s crucial to heed industry standards about maintaining a safe working distance. That’s why more electricians and utility companies are turning to thermal imaging as a practical and more...
