What is the purpose of a hazardous energy control program in a maintenance facility?

• A. To protect workers from unexpected energization by standardizing procedures, training, and compliance for energy isolation and de-energization.
• B. To maximize production speed.
• C. To reduce noise.
• D. To track inventory.

Answer: (A)

Controlling hazardous energy prevents injuries from unexpected machine energization or release of stored energy during maintenance. The program standardizes how energy sources are isolated and de-energized and requires training and ongoing compliance so workers are protected. It uses written procedures for each piece of equipment, applies lockout or tagout devices to physically prevent re-energizing, and requires verification that energy is truly off before work begins, with periodic inspections to keep the controls effective. It covers electrical, hydraulic, pneumatic, mechanical, thermal, and stored energy (like springs or compressed air) that could cause harm if released. For example, before servicing a machine, you shut off power, apply a lock and/or tag, verify there is no energy, and only then perform maintenance; energy is restored only after all work is done and devices are removed. The other options don’t address worker safety from unexpected energization or stored energy.
