Control of Hazardous Energies Standard / V3 2023-12-04

The participants shall:

Engage in the discussions and share understandings about:

a. 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

b. 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

Practise performing safe isolation and safe dissipation of pressure in a pressure system and select the correct test or measurement points in accordance with a hydraulic diagram:

a. identify the isolation and ensure the isolation is carried (*If an electrical isolation is required, it must be performed by the instructor as an Electrical Qualified Person)

b.

perform the hydraulic isolation

c.

dissipate any pressure

d.

secure the isolation against re-energisation

e.

prove absence of pressure

ELEMENT 5.6 - COMPONENT REPLACEMENT IN PRESSURE SYSTEMS

Learning objectives:

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 practise 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
