Product Overview

Identify and control organisational risks associated with Gas Welding and Cutting at a management and systems level, covering governance, planning, procurement, facilities, and workforce controls. This Risk Assessment supports executive Due Diligence, aligns with WHS legislation, and helps protect your business from compliance breaches and operational liability.

Risk Categories & Hazards Covered

This document assesses risks and outlines management controls for:

  • Governance, Legal Compliance and WHS Duties: Assessment of PCBU obligations, officer due diligence, consultation arrangements, and alignment of gas welding and cutting activities with the WHS Act, Regulations and internal policies.
  • Hazard and Risk Management System: Management of hazard identification, formal risk assessment, risk registers, and review processes specific to gas welding, cutting and allied processes.
  • Plant, Equipment and Gas Procurement: Evaluation of selection, specification and procurement controls for welding plants, regulators, hoses, flashback arrestors, cylinders and associated equipment to ensure compliance and fitness for purpose.
  • Storage, Handling and Facility Design: Assessment of gas cylinder storage areas, segregation of incompatible gases, fire separation, signage, traffic flow, and workshop layout to minimise ignition and explosion risks.
  • Maintenance, Inspection and Asset Management: Management of inspection schedules, tagging, defect reporting, repair protocols and lifecycle control for welding equipment, cylinders, valves and accessories.
  • Competency, Training and Supervision: Evaluation of competency requirements, high-risk skills training, refresher training, supervision levels and verification of competency for operators, supervisors and contractors.
  • Procedures, Work Authorisation and Hot Work Permits: Development and control of documented procedures, job planning, isolation requirements, hot work permit systems and authorisation processes for welding and cutting tasks.
  • Ventilation, Fume and Exposure Control Systems: Assessment of local exhaust ventilation, general ventilation, fume extraction, monitoring, and controls for hazardous fumes, gases and heat exposure.
  • Emergency Preparedness and Response: Planning for gas leaks, fires, flashbacks, explosions and medical emergencies, including emergency equipment, spill kits, alarm systems, and evacuation procedures.
  • Incident Reporting, Investigation and Continuous Improvement: Protocols for reporting near misses and incidents, root cause analysis, corrective actions, and monitoring of performance indicators related to gas welding and cutting operations.

Who is this for?

This Risk Assessment is designed for Business Owners, Operations Managers, Safety Managers and WHS Advisors responsible for planning, approving and overseeing gas welding and cutting activities within their organisation or projects.

Hazards & Risks Covered

Hazard Risk Description
1. Governance, Legal Compliance and WHS Duties
  • • Failure to identify and comply with WHS Act 2011 and WHS Regulation requirements relating to welding, hazardous chemicals, hazardous atmospheres and plant
  • • Absence of documented WHS management system covering gas welding and cutting activities across all sites
  • • Unclear allocation of WHS duties and due diligence obligations for Officers, PCBUs and workers involved in welding and cutting work
  • • Inadequate consultation arrangements with workers and Health and Safety Representatives (HSRs) regarding changes to welding and cutting processes or equipment
  • • Lack of documented approval process for introducing new gases, regulators, torches or cutting systems
  • • No process to ensure that contractors and labour hire workers conducting gas welding and cutting comply with organisational WHS requirements
2. Hazard and Risk Management System
  • • Lack of formal, documented risk assessments for gas welding and cutting across different work environments (workshop, field, confined spaces, elevated work platforms)
  • • Risk assessments focusing only on task steps and not on systemic issues such as supervision, design, maintenance and emergency management
  • • Inconsistent application of the hierarchy of control leading to over‑reliance on administrative controls and PPE
  • • Failure to review risk assessments following incidents, near misses, equipment changes or changes to materials and work environments
  • • No structured process for identifying interaction risks with other activities (e.g. hot work near flammable storage, traffic routes, or public access)
3. Plant, Equipment and Gas Procurement
  • • Procurement of incompatible or sub‑standard cylinders, regulators, hoses, torches or flashback arrestors that do not comply with relevant Australian Standards
  • • Purchase of equipment without considering pressure ratings, duty cycles, environmental conditions and compatibility with existing systems
  • • Lack of lifecycle planning for gas welding and cutting plant, including inspection, testing, replacement intervals and end‑of‑life disposal
  • • Acquisition of non‑standard components or modified equipment from multiple suppliers leading to complexity and incorrect set‑up
  • • Procurement processes driven solely by cost, with no structured WHS evaluation of suppliers or equipment
4. Storage, Handling and Facility Design
  • • Inadequate design of gas cylinder storage areas leading to exposure to heat sources, vehicle impact, poor ventilation or unauthorised access
  • • Improper segregation of flammable and oxidising gas cylinders and storage with incompatible materials such as combustible goods or corrosive chemicals
  • • Poorly designed workstations with limited space, cluttered layouts, or trip hazards affecting safe movement with hoses and trolleys
  • • Insufficient fixed fire protection systems, fire extinguishers, or emergency isolation valves in welding and cutting areas
  • • Lack of systems controlling cylinder transport, securing and upright storage, and movement between storage and work areas
5. Maintenance, Inspection and Asset Management
  • • Lack of systematic inspection and maintenance of regulators, hoses, flashback arrestors, torches and trolleys leading to gas leaks, flashbacks and equipment failure
  • • Use of damaged or out‑of‑test cylinders, or equipment used beyond manufacturer’s recommended service life
  • • Informal repairs or modifications conducted by unqualified personnel using non‑approved parts or methods
  • • No documented schedule for testing flashback arrestors, leak testing and replacement of hoses and O‑rings
  • • Failure to remove defective equipment from service and clearly tag or quarantine it to prevent re‑use
6. Competency, Training and Supervision
  • • Workers performing gas welding and cutting without adequate theoretical and practical training in the hazards and controls
  • • Supervisors lacking specific knowledge of gas welding and cutting risks and therefore unable to verify safe systems of work
  • • No formal competency assessment or refresher training, leading to skill fade and unsafe practices becoming normalised
  • • Contractors and labour hire workers not receiving site‑specific induction or verification of their welding qualifications and experience
  • • Limited training in emergency response to gas leaks, flashbacks, fires or injuries related to welding and cutting
7. Procedures, Work Authorisation and Hot Work Permits
  • • Absence of standardised procedures governing how gas welding and cutting work is planned, authorised and monitored
  • • Inconsistent use of hot work permits, especially in non‑routine locations or during after‑hours work
  • • Permits and procedures focusing on paperwork rather than effective risk control and verification in the field
  • • Lack of coordination of gas welding and cutting activities with other high‑risk work such as confined space entry, working at height or operations involving flammable liquids
  • • Failure to define clear criteria for when welding and cutting work must cease due to environmental conditions or conflicting tasks
8. Ventilation, Fume and Exposure Control Systems
  • • Systemic failure to control exposure to welding fumes, gases and combustion products where gas welding and cutting is carried out in enclosed or poorly ventilated spaces
  • • Reliance on respiratory protective equipment as the primary control instead of engineering solutions such as local exhaust ventilation
  • • No monitoring or assessment of atmospheric contaminants or oxygen levels in areas where welding and cutting is conducted
  • • Inadequate integration of welding and cutting controls with confined space entry procedures and atmospheric testing regimes
  • • Lack of maintenance and effectiveness checks for installed fume extraction and general ventilation systems
9. Emergency Preparedness and Response
  • • Lack of coordinated emergency response plans for gas leaks, cylinder fires, flashbacks, explosions and welding‑related injuries
  • • Workers and supervisors not trained or drilled in emergency shutdown procedures for gas supplies and equipment
  • • Inadequate communication systems to raise the alarm and coordinate evacuation if a gas‑related incident occurs
  • • Emergency equipment (e.g. gas isolation valves, fire extinguishers, first aid equipment) not readily accessible or clearly identified in welding and cutting areas
  • • No liaison with emergency services regarding storage of gas cylinders and potential worst‑case scenarios
10. Incident Reporting, Investigation and Continuous Improvement
  • • Under‑reporting of gas welding and cutting near misses, including minor leaks, small fires or equipment malfunctions
  • • Superficial incident investigations that focus on operator error rather than systemic issues such as design, maintenance, supervision or training gaps
  • • Lack of trend analysis to identify recurring issues related to gas welding and cutting across sites or departments
  • • Failure to implement, track and review corrective and preventive actions arising from incidents and audits
  • • Limited mechanisms for sharing lessons learned and best practice improvements with all workers involved in welding and cutting
