Control of Hazardous Energies Standard / V4 02052025
47) The participants can perform component replacement in pressure systems in a safe and correct manner (Skills, intermediate level)
48) The participants can act independently in connection to component replacement in pressure systems (Ability, intermediate level)
The demonstration and practice in this element should be done using the equipment that remains in a safe condition from the previous element (element 5.5) The key issue for the combined practice is to be able to put the pressure system in a safe condition so a component can be replaced. There could be many options with different complexity (including not only pressure, but electrical and mechanical energy) An example could be a “pressure relief valve” or a “manual directional control valve” that requires isolation of the pressure (motor pump) and dissipation of stored energy on a system accumulator
Note
The instructor shall:
Demonstrate how to perform component replacement safely and correctly in pressure systems:
a.
ensure good housekeeping
b.
ensure cleanliness
c.
torque up
d. even after proving the pressure is zero, extreme caution must be taken when removing any component in case of trapped pressure
Ask the participants key questions about how to perform component replacement safely and correctly in pressure system e.g.:
a. how would the participants restate or summarise how to perform component replacement safely and correctly in pressure systems in their own words?
b. what happened e.g. what actions were performed by the instructor to perform the component replacement safely and correctly?
c.
why were these actions performed?
Facilitate practice for the participants in performing component replacement safely and correctly in pressure systems
Give constructive feedback to the participants’ performance throughout the activities of this element
The participants shall:
