Question 1 of 27070

Before doing any work on a hydraulic system equipped with accumulators, you should __________.

🔍 Key Concepts

• Hydraulic accumulators store energy, even when pumps and valves are secured • Safe maintenance practice on pressurized systems (hydraulic, pneumatic, steam, etc.) • Why releasing pressure/energy is critical before opening any part of the system

💭 Think About

• Think about what an accumulator actually does in a hydraulic system—does it add or remove stored energy? • Which choice would reduce the danger of sudden movement or fluid spray when you disconnect or open the system? • Look for the option that matches standard lock-out/tag-out style procedures for pressurized systems.

✅ Before You Answer

• Which option ensures no stored pressure or energy remains in the accumulator? • Is any option suggesting the use of oxygen in contact with oil or hydraulic fluid? Consider fire/explosion risk. • Which choice is consistent with general de-energizing and depressurizing rules before maintenance?
