    Purpose of the Free Safe Operating Procedure (Exhaust Removal) Template

    Effectively managing the risks associated with vehicle and equipment exhaust is a critical WHS responsibility, particularly in enclosed or poorly ventilated areas. This free Safe Operating Procedure (Exhaust Removal) template provides a structured starting point for documenting the process of safely managing exhaust fumes.

    The purpose of this Safe Operating Procedure is to help your business establish and communicate a clear, step-by-step process for controlling hazardous airborne contaminants like carbon monoxide, nitrogen oxides, and diesel particulate matter. Implementing a documented procedure helps fulfil your duty of care as a PCBU and provides a vital training tool for workers. This SOP can be integrated as a key component of your broader WHS management systems.

    How to use the Free Safe Operating Procedure (Exhaust Removal) Template

    This document is a customisable template designed for adaptation to your specific workplace. Upon downloading the DOCX or PDF file, you must review and modify it to align with your site's unique environment, equipment, and processes.

    It is crucial to remember that this is a template, not a finished document. We have provided a structured starting point, but you must customise it to reflect the specific equipment, layout, ventilation, and work practices of your site.

    Consultation with workers and relevant stakeholders is a mandatory step in this process to ensure the procedure is practical and effective. Ensure the final document is approved, communicated to all relevant personnel, and readily accessible at the point of work. This process is similar for other task-specific procedures, like our free Air Compressor SOP template.

    What this Safe Operating Procedure covers

    Our template provides a comprehensive framework based on Australian WHS practice, prompting you to detail key safety information including:

    • Hazard Identification: Outlining specific dangers associated with exhaust fumes from petrol and diesel engines (e.g., asphyxiation, carcinogen exposure, irritation).
    • Risk Assessment: A section to document the outcomes of a risk assessment for tasks involving running engines indoors or in confined spaces.
    • Control Measures: Prompts to detail controls based on the hierarchy of control, such as direct source capture systems (hoses connected to tailpipes), general mechanical ventilation, specifying when doors and windows must be open, and limitations on engine idling times.
    • Personal Protective Equipment (PPE): Specification of any required PPE, noting that PPE is a last resort when higher-level controls are not feasible. This may include respiratory protection in specific, assessed situations.
    • Training and Competency: Requirements for worker training on the hazards of exhaust fumes and the correct use of control measures.
    • Emergency Procedures: Steps to take in case of an incident, such as exposure, system failure, or activation of a carbon monoxide alarm.

    When to use it

    This Safe Operating Procedure is essential for any workplace where internal combustion engines are operated in a way that could expose people to harmful levels of exhaust fumes. This includes, but is not limited to:

    • Vehicle and equipment maintenance workshops.
    • Enclosed car parks and loading bays.
    • Warehouses where forklifts, telehandlers, or other plant operate.
    • Tunnelling and underground work environments.
    • Any indoor or confined area where portable generators, pressure washers, or other engine-driven equipment is used.
    • Facilities where plant such as that detailed in our Grader SOP might be maintained or started in an enclosed workshop.

    Who should use it

    This procedure is designed for use by multiple roles within an organisation. Persons Conducting a Business or Undertaking (PCBUs) and managers should use it to establish and formalise safe work practices.

    Supervisors are responsible for implementing the SOP on the floor, ensuring workers follow the outlined procedures and use controls correctly. WHS officers can use the template to guide risk assessments and develop training materials.

    Finally, workers who operate or work near engine-powered equipment must be trained on and follow the procedure to protect their own health and safety and that of their colleagues. Regular WHS compliance auditing can verify that these procedures are being consistently applied across the business.

    By customising and implementing this procedure, you take a significant step towards managing a serious workplace health risk. For expert assistance in tailoring this or other procedures to your specific operational needs, our WHS consulting team can provide tailored support.

    Common mistakes

    Common mistakes to avoid

    • Relying solely on opening a door or window for ventilation in enclosed spaces.
    • Not maintaining the exhaust extraction system, leading to blocked filters or cracked hoses.
    • Assuming outdoor or semi-enclosed areas are always safe from exhaust fume build-up, especially in calm conditions.
    • Failing to train workers on the specific risks of exhaust fumes and the correct use of controls.

    Did you know

    Invisible Danger

    Carbon monoxide (CO) is a major component of engine exhaust. It is colourless, odourless, and tasteless, and can cause incapacitation or death in minutes at high concentrations, often before the victim is aware of the danger.

    Diesel Fume Classification

    In 2012, the International Agency for Research on Cancer (IARC) classified diesel engine exhaust as a Group 1 carcinogen, placing it in the same category as asbestos and tobacco smoke as being known to cause cancer in humans.

    FAQ

    Frequently asked questions

    01What are the main hazards of engine exhaust fumes in the workplace?
    The primary hazards include toxic gases like carbon monoxide (CO), which can cause chemical asphyxiation, and nitrogen oxides (NOx). Exhaust also contains fine particulate matter and carcinogens (like benzene and those in diesel exhaust) that can lead to serious long-term health effects, including cancer and respiratory disease.
    02Is a specific exhaust removal system required by law in Australia?
    Australian WHS law does not mandate a specific type of system but requires PCBUs to manage risks and ensure worker exposure to airborne contaminants does not exceed the workplace exposure standards. In many indoor settings, a mechanical extraction system is the only reasonably practicable way to achieve this.
    03How often should an exhaust removal SOP be reviewed?
    An SOP should be reviewed regularly, typically every one to two years, or whenever there is a change to equipment, processes, or the work environment. It must also be reviewed after any incident or when monitoring shows that control measures are no longer effective.
    04Can this SOP be used for both diesel and petrol engine exhaust?
    Yes, the template is designed to be adapted for controlling hazards from both diesel and petrol engines. You should customise it to include specific information relevant to the types of engines and fuels used at your workplace, noting that the composition and associated risks of their exhausts differ.
