🔍 Key Concepts

• Hydraulic pressure hazards in starting systems • Safe isolation procedures before servicing pressurized systems • How stored energy (pressure, springs, accumulators) is removed before working on machinery

💭 Think About

• Which action directly removes stored energy that could cause sudden movement or fluid release while you are working? • Which options are about making the system ready to run versus making the system safe to open? • If you disconnect a hose or open a fitting, what condition must the internal pressure be in to avoid injury or damage?

✅ Before You Answer

• Identify which choice actually eliminates pressure rather than just controlling it • Ask: If I did this step and then loosened a fitting, could fluid still be under dangerous pressure? • Think about standard lock-out/tag-out ideas: you must remove or discharge stored energy before opening the system
