Cryogenics SWMS

Product Overview

This Cryogenics Safe Work Method Statement (SWMS) is developed to identify hazards, assess risks, and implement effective controls when working with cryogenic substances on Australian worksites. It is a comprehensive document that covers multiple aspects of cryogenic safety management to support robust WHS compliance and risk mitigation.

Activities & Specific Tasks Covered

This document includes specific risk controls for:

• Safe handling, transfer, and decanting of cryogenic substances such as liquid nitrogen, liquid oxygen, and liquid argon
• Selection, inspection, and use of suitable personal protective equipment (PPE) for cryogenic work, including face shields, gloves, and aprons
• Storage and segregation of cryogenic liquids in compliant vessels, dewars, and storage areas
• Management of extreme cold hazards, including prevention of cold burns, frostbite, and cold-induced material failure
• Control of asphyxiation risks from oxygen displacement and oxygen-enriched or oxygen-deficient atmospheres
• Safe connection, operation, and disconnection of cryogenic transfer lines, valves, and associated equipment
• Ventilation requirements and monitoring of confined or poorly ventilated spaces where cryogenic gases may accumulate
• Emergency response procedures for cryogenic spills, leaks, and uncontrolled releases
• Safe transport and manual handling of cryogenic cylinders, dewars, and mobile vessels on site
• Inspection, maintenance, and defect reporting for cryogenic storage and delivery systems
• Training, competency, and authorisation requirements for personnel working with cryogenic substances
• Signage, labelling, and communication of cryogenic hazards to all workers and visitors

Who is this for?

This SWMS is designed for laboratories, medical and research facilities, industrial gas suppliers, manufacturing plants, cold storage operations, and site supervisors managing any work involving cryogenic substances.
