Identifying safety procedures should include explaining

all safety precautions, procedures, guidelines, and manufacturer specifications for working on hydraulic systems
all required PPE for the selected task
the safe use of appropriate tools and equipment
procedures in a systematic plan using the repair or manufacturer manual
the importance of relieving hydraulic pressure in an operating system
the importance of locking cylinder stops, locks, or blocks for raised equipment or components when servicing or performing maintenance on hydraulic systems
hazards related to hydraulic systems, such as
- burns from the hot, high-pressure spray of fluid when changing lines, connections, fittings, or filters
- bruises, cuts, or abrasions from flailing hydraulic lines
- hydraulic injection of fluid into the skin (e.g., pinhole leak injuries, improper coupling)
the importance of inspecting for leaks, given hydraulic systems store fluid under high pressure
why safe and efficient hydraulic system performance requires general maintenance
how proper coupling of high- and low-pressure hydraulic components and pressure relief valves is related to safety
the importance of using a chain hoist, floor jack, or other type of assistive device when the removal of heavy hydraulic pumps or control valves is required.
