Control of Hazardous Energies Standard / V4 02052025

26) The participants can explain the hazards related to, and safety measures needed, when taking an oil sample from a hydraulic system (Knowledge, intermediate level)

The instructor shall:

Facilitate a learning activity with the participants about the hazards related to, and safety measures needed when, taking an oil sample from a hydraulic system. Examples of safety measures could be:

a. follow a manufacturers guideline e.g. an approved work instruction

b.

reducing the system pressure

The participants shall:

Engage in the learning activity and share understandings about the hazards related to, and safety measures needed when, taking an oil sample from a hydraulic system

ELEMENT 3.6 - HAZARDS RELATED TO PRE-CHARGING AN ACCUMULATOR

Learning objective:

27) The participants can explain the hazards related to, and safety measures for, applying pre-charge to an accumulator in a WTG environment (Knowledge, intermediate level)

The instructor shall:

Present examples of situations, or scenarios, in a WTG environment with hazards related to applying pre-charge to an accumulator:

a.

environment aspect (asphyxiation)

b.

freeze burns from use of gases

c.

unexpected movement

Accumulators are part of a system that is used to move an actuator (normally a piston/cylinder like in the blades or a brake calliper) The unexpected movement refers to these actuators moving due to other external forces, like for instance with a blade, if the pressure is released from the accumulator, but the blade is not locked in place
