Safety training
Control of Hazardous Energies Standard / V3 2023-12-04
Present examples to the participants of relevant situations or scenarios from a WTG environment with hazards of fluids under pressure
Facilitate practice for the participants in identifying these hazards and deciding on relevant actions and/or mitigation measures to avoid these hazards of fluids under pressure
Give constructive feedback to the participants´ performance throughout the activities in this element
The participants shall:
Engage in the learning activities and share understandings about the hazards of fluids under pressure
Engage in identifying the hazards of fluids under pressure in the examples and share understandings about mitigation measures to avoid the hazards of fluids under pressure
ELEMENT 3.2 - TRAPPED PRESSURE AND STORED ENERGY IN A PRESSURE SYSTEM
Learning objectives:
20) The participants can explain the hazards of trapped pressure and stored energy in a pressure system in a WTG environment (Knowledge, intermediate level)
21) The participants can explain how to handle the hazards of, and mitigation measures, for trapped pressure and stored energy in a pressure system in a WTG environment (Knowledge, intermediate level)
The instructor shall:
Present examples to the participants of situations or scenarios in a WTG environment with hazards of trapped pressure and stored energy in a pressure system (e.g. pressured trapped behind valves or created by temperature changes)
Facilitate practice for the participants to identifying the hazards of trapped pressure and stored energy in a pressure system in the situations or scenarios from a WTG environment
Ask the participants key questions about how to handle the hazards of, and mitigation measures for, trapped pressure and stored energy in a pressure system. Examples of mitigation measures:
a. controlled release of pressure (venting a pressure fluid system e.g. an accumulator)
b. removing load from the system (removing the force acting on a cylinder e.g. locking a blade)
Give constructive feedback to the participants´ identifications of and answers about the mitigation measures for the risks related to trapped pressure and stored energy in a pressure system
