Control of Hazardous Energies Standard / V4 02052025

Engage in discussions and share their understandings or experiences about the importance of always testing for the absence of pressure before working on a pressure system

Engage in the exercises and practise using a pressure manometer to check for the absence of pressure in a correct and safe manner

ELEMENT 5.5 - SAFE ISOLATION AND SAFE DISSIPATION OF PRESSURE IN A PRESSURE SYSTEM

Learning objectives:

45) The participants can perform safe isolation and safe dissipation of pressure in a pressure system (Skills, intermediate level)

46) 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
