What safety procedures must be observed before performing maintenance on ALRE equipment?

• A. Lockout/tagout, release stored energy, verify depressurization, and follow applicable safety procedures
• B. Regularly inspect only the exterior components
• C. Notify the chain of command that maintenance is happening
• D. Track maintenance in the logbook after completion

Answer: (A)

Before doing any maintenance on ALRE equipment, you must control all energy sources and make sure the system cannot move or release energy while you work. This is why lockout/tagout is essential: you isolate electrical, hydraulic, pneumatic, and any other power sources and apply a lock and a tag to prevent re-energizing the equipment. This step protects you from unexpected startup or release of energy that could injure you or others.

Releasing stored energy and depressurizing the system are the next critical actions. Systems in ALRE gear often contain hydraulic or pneumatic lines, charged accumulators, springs, or other stored energy that can lash out when work begins. Safely releasing and dissipating that energy, draining fluids if required, and bringing pressures to zero eliminates the risk of sudden movement or pressure bursts during maintenance. Verifying depressurization means double-checking with appropriate gauges or test instruments to be certain there is no residual energy before you proceed.

Following all applicable safety procedures ties the work to established standards and site-specific rules. This includes using permits as required, donning the proper PPE, and adhering to the facility’s safe-work practices and ALRE maintenance instructions. Together, these steps create a safer environment for maintenance and help prevent injuries from unexpected energy release, movement, or exposure to hazardous conditions.

Resting on these steps, rather than just inspecting exterior components, ensures you address the real hazards you’ll encounter during maintenance. Notifying your chain of command or logging after the work are important administrative tasks, but they do not replace isolating energy sources, releasing stored energy, or confirming the system is depressurized before you begin work.
