Product Overview

Summary: This SOP sets out clear, practical fire and safety procedures specifically for HVAC worksites, where hot works, electrical systems and confined spaces significantly increase fire risk. It helps Australian businesses control ignition sources, manage flammable materials and respond effectively to emergencies, protecting workers, property and compliance obligations.

HVAC installation, maintenance and commissioning often involve hot works, live electrical components, combustible dusts and work in ceiling spaces and plant rooms – all of which significantly elevate the risk of fire and smoke incidents. This Fire and Safety Procedures in HVAC Worksites SOP provides a structured, step-by-step framework for preventing fires, managing ignition sources and responding rapidly and safely when something goes wrong. It is tailored to the realities of Australian HVAC work, including work in existing occupied buildings, construction sites, and remote plant areas such as rooftops and basements.

By implementing this SOP, businesses create a consistent, defensible approach to fire safety that aligns with WHS legislation, building fire safety requirements and client expectations. The document covers pre-start fire risk assessments, permit-to-work requirements for hot works, safe handling of flammable gases and materials, isolation of electrical and HVAC systems, housekeeping standards, and clear emergency response actions for workers and supervisors. It helps reduce the likelihood of fires caused by brazing or welding, electrical faults, blocked airflow, dust build-up and improper use of temporary heaters or power tools. This SOP also supports training, contractor management and incident reporting, giving organisations a practical tool to demonstrate due diligence and protect both workers and assets.
