Product Overview

Summary: This Emission Control Inspection SOP provides a clear, step-by-step framework for inspecting, testing, and maintaining emission control systems in Australian workplaces. It helps organisations reduce harmful air emissions, protect worker health, and demonstrate compliance with WHS and environmental obligations.

This Emission Control Inspection Safe Operating Procedure is designed for Australian businesses that operate plant, equipment, vehicles, or fixed installations where emissions must be controlled and monitored. From workshop extraction systems and spray booths to diesel plant, generators, and industrial process equipment, the SOP sets out a consistent method for planning, conducting, and recording inspections of emission control components. It focuses on protecting workers from harmful airborne contaminants while supporting compliance with both WHS and environmental requirements.

The document translates regulatory expectations into practical on-the-ground actions: what must be checked, how often, by whom, and what to do if equipment fails inspection. It addresses common pain points such as inconsistent inspections, poor recordkeeping, uncertainty around acceptable emission levels, and reactive maintenance that only occurs after a complaint or incident. By implementing this SOP, businesses gain a defensible, auditable process that reduces health risks from fumes, gases and particulates, minimises equipment downtime, and supports cleaner, safer operations across workshops, depots, and industrial sites.

Key Benefits

• Ensure consistent, documented inspection of emission control systems across all sites and assets.
• Reduce worker exposure to harmful fumes, exhaust gases, vapours and airborne particulates.
• Demonstrate compliance with WHS duties and relevant environmental and air quality requirements.
• Identify defects early to prevent costly breakdowns, non-conformances and regulatory enforcement action.
• Standardise training and expectations for technicians, supervisors and contractors involved in inspections.
