Pressure Fluid Safety module
The instructor shall:
Give constructive feedback to the participants´ above group discussions.
ELEMENT 3.6 - HAZARDS RELATED TO PRE-CHARGING AN ACCUMULATOR
Learning objective:
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:
Environment aspect (asphyxiation).
Freeze burns from use of gasses
Unexpected movement
Note: 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. Facilitate practice for the participants in identifying the hazards related to applying pre-charge to an accumulator in the situations or scenarios. Ask the participants to provide answers to key questions about how to mitigate the hazards of related to applying pre-charge to an accumulator in the situations or scenarios.
The participants shall:
Engage in the practice of identifying the hazards related to applying pre-charge to an accumulator in the situations or scenarios. Engage in answering questions about how to mitigate the hazards related to applying pre-charge to an accumulator in the situations or scenarios.
The instructor shall:
Give constructive feedback to the participants´ identification (previous points) of the hazards related to applying pre-charge to an accumulator and answers to safety measures for the hazards related to applying pre-charge to an accumulator in the situations or scenarios.
