    Purpose of the Free Safe Operating Procedure (Coolant Change) Template

    Effectively managing routine vehicle and machinery maintenance is fundamental to workplace safety. Our Free Safe Operating Procedure (Coolant Change) Template offers a comprehensive, structured starting point for organisations to formalise their process for this common but hazardous task.

    This document helps standardise procedures to minimise risks such as chemical exposure, thermal burns, and environmental contamination. By outlining the required steps, safety controls, and personal protective equipment (PPE), this SOP helps you establish a safe system of work aligned with Australian WHS principles and practices.

    How to use the Free Safe Operating Procedure (Coolant Change) Template

    This Safe Operating Procedure template is available for download as a DOCX file for easy editing or as a PDF for straightforward printing and distribution. To use it effectively, download the document and integrate the specific details of your workplace.

    This includes identifying the exact types of machinery, coolants used, local environmental regulations, and emergency procedures. It is crucial to understand that this template is a starting point.

    We have designed it to be adapted; you must customise it to reflect the specific equipment, chemicals, and environmental conditions at your worksite before implementation.

    Key Hazards in Coolant Change Procedures

    Changing engine coolant involves several significant hazards that must be controlled. The primary risks include thermal hazards from hot engine components and pressurised coolant, which can cause severe burns.

    There are also chemical hazards associated with coolant ingredients like ethylene glycol, which is toxic if ingested and can cause skin or eye irritation upon contact. Manual handling risks exist when lifting heavy containers of new or waste coolant, and there is a significant environmental risk from spills if not contained properly. Many workshop tasks share similar risks that require formalised procedures, as seen in our Air Compressor SOP template.

    When to Use This Safe Operating Procedure

    This SOP should be used every time a coolant change is performed, whether as part of a scheduled maintenance program or as a one-off repair. It serves as a practical guide for workers executing the task and as a training document for new or inexperienced employees.

    It should also be readily available for reference during toolbox talks on vehicle maintenance safety. Integrating such procedures consistently ensures that safety is not left to chance and becomes an embedded part of your operational culture. This process-driven approach is a cornerstone of effective WHS management systems.

    Who Should Use It

    This Safe Operating Procedure is intended for all personnel involved in vehicle and equipment maintenance, including qualified mechanics, trade assistants, apprentices, and mobile plant operators who perform their own basic servicing. Supervisors and safety managers should also use the document to ensure they are providing a safe system of work and to verify that correct procedures are being followed.

    The principles are scalable from light vehicle workshops to heavy industrial settings, where maintaining equipment like that covered in our Dozer SOP template is a daily activity.

    Personal Protective Equipment (PPE) Requirements

    The correct selection and use of PPE is a critical control measure for this task. The SOP specifies the minimum required PPE, which typically includes safety glasses or a face shield to protect against splashes, chemical-resistant gloves (e.g., nitrile) to prevent skin contact, and enclosed safety footwear.

    Depending on the specific circumstances, additional PPE like aprons or coveralls may be necessary. Ensuring workers understand and use the correct PPE for each task is a universal safety requirement, whether they are changing coolant or operating equipment detailed in our FREE Telehandler SOP Template.

    Integrating the SOP into Your Safety Framework

    A Safe Operating Procedure is most effective when it is part of a living safety system, not just a document filed away. This coolant change SOP should be included in worker inductions and job-specific training.

    It should be reviewed regularly and updated whenever a process, chemical, or piece of equipment changes. Regular reviews of your procedures are a key part of maintaining safety standards, often verified through professional WHS compliance auditing.

    Common mistakes

    Common mistakes to avoid

    • Opening a radiator cap while the system is hot, leading to severe burns from pressurised steam and coolant.
    • Mixing different types of coolant, which can cause chemical reactions, gelling, and blockages in the cooling system.
    • Disposing of old coolant improperly, such as pouring it down a stormwater drain, which causes environmental pollution.
    • Failing to wear appropriate PPE, particularly safety glasses and chemical-resistant gloves, leading to eye injuries or skin irritation.

    • Work Health and Safety Act (Harmonised) — Provides the primary duties for protecting workers and other people from work health and safety risks.
    • Work Health and Safety Regulations (Harmonised) — Sets out requirements supporting the management of workplace hazards and risks.

    The following codes may be relevant to this type of work.

    • Managing WHS Risks Code of Practice — Provides practical guidance on identifying hazards, assessing risks and applying effective controls.

    Did you know

    The Colour Myth

    Coolant colour does not reliably indicate its type or specification. Always refer to the manufacturer's specifications or the product data sheet, as mixing incompatible coolants can cause gelling and serious engine damage.

    Sweet but Deadly

    The sweet smell of ethylene glycol, the primary component in most coolants, can attract pets and children. However, it is highly toxic and can be fatal if ingested, making secure storage and spill cleanup critical.

    FAQ

    Frequently asked questions

    01What should be included in a coolant change SOP?
    A comprehensive coolant change SOP should detail the task's hazards, required PPE, a step-by-step procedure for draining, flushing, and refilling, and emergency response actions for spills or exposure.
    02Is ethylene glycol coolant dangerous?
    Yes, ethylene glycol, a common ingredient in coolant, is toxic if ingested and can cause significant skin and eye irritation. Proper handling using correct PPE is essential to prevent exposure and ensure worker safety.
    03How do you dispose of used engine coolant in Australia?
    Used coolant is classified as a controlled or prescribed waste. It must be collected in a dedicated, sealed, and clearly labelled container and disposed of through a licensed waste management facility, never down a drain or onto the ground.
    04Why can't I just top up coolant with water?
    Coolant is a carefully balanced mixture of water, anti-freeze, and anti-corrosion inhibitors. Adding only water dilutes these agents, reducing the coolant's boiling point and freezing point and diminishing its ability to protect the engine from corrosion.
