Which of the following is a common safety practice when working with hydraulic systems?

Depressurizing the system is a crucial safety practice when working with hydraulic systems. Hydraulic systems operate under high pressure, and any failure to properly depressurize can result in serious injuries, equipment damage, or unintended discharge of hydraulic fluid. By depressurizing, technicians ensure that the system is safe to work on, significantly reducing the risk of accidents caused by the release of pressurized fluid.

This procedure typically involves following specific protocols to release pressure from the system safely before performing any maintenance or repairs, making it an essential step in ensuring worker safety.

The other practices listed hinder safety. For instance, using gloves may be advised in certain conditions to protect skin from hazardous substances, and tackling hydraulic work while alone could lead to dangerous situations without backup. Similarly, introducing excess fluid can lead to over-pressurization, creating additional safety risks. Therefore, depressurizing the system stands out as an essential practice in ensuring the safety and integrity of hydraulic work.
