Control of Hazardous Energies Standard / V5 DRAFT REVIEW - Oct 2025
31) The participants can select the correct test or measurement points in accordance with a hydraulic diagram (Skills, advanced level)
The instructor shall:
Explain and demonstrate how to perform safe isolation and safe dissipation of pressure in a pressure system and selecting the correct test or measurement points in accordance with a hydraulic diagram:
a.
identify the isolation
b.
perform the isolation
c.
dissipate any pressure
d.
secure the isolation against re-energisation
e.
prove absence of pressure
Lead discussions with the participants about the steps performed in the safe isolation and pressure system and the selection of the correct test or measurement points in accordance with a hydraulic diagram:
a.
which steps were performed?
b.
how was each step performed?
c.
why was each step performed?
Lead discussion about the differences in the safe dissipation of pressure in a compressible pressure fluid (e.g. nitrogen) system versus a non-compressible pressure fluid (e.g. hydraulic) system
Facilitate practice for the participants in performing safe isolation and safe dissipation of pressure in a pressure system and selecting the correct test or measurement points in accordance with a hydraulic diagram and give constructive feedback to the participants´ practice throughout:
a. identify the isolation (normally the CB that supplies the electrical motor that moves the pressure pump)
b. perform the isolation (needs to be a Authorised Person)
c.
dissipate any pressure
d.
secure the isolation against re-energisation
e.
prove absence of pressure
