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
