    Purpose of the Free Verification of Competency (Trailer-Mounted Generator) Template

    A Verification of Competency (VOC) is a crucial process for any person conducting a business or undertaking (PCBU) to confirm that their workers have the current skills and knowledge to operate equipment safely. This Free Verification of Competency (Trailer-Mounted Generator) Template provides a structured framework for assessing an individual’s ability to safely use, move, and maintain a trailer-mounted generator.

    Using such a template helps demonstrate due diligence and ensures that operators understand the specific risks associated with this type of mobile plant, including electrical hazards, towing and manual handling, noise, and exhaust fumes.

    Implementing a robust VOC process is a fundamental part of an organisation's safety obligations. It fits within the broader framework of your site's safety procedures, which should be managed systematically.

    A well-documented safety program ensures that training, assessment, and operational processes are consistent and effective, with services for WHS management systems able to provide structure and support for these activities.

    How to Use the Free Verification of Competency (Trailer-Mounted Generator) Template

    This template is designed to be a practical tool for supervisors and safety officers. The process is straightforward:

    • Download the resource in your preferred format (DOCX for easy editing or PDF).
    • Customise the checklist to reflect the specific make and model of the generator used at your workplace, along with your site's unique environmental conditions and safe work procedures.
    • Have a competent assessor (a person with the requisite knowledge and experience) observe the worker performing the tasks listed.
    • The assessor uses the template to record their observations and make a final determination of competence.
    • Sign and file the completed document as a formal record.

    Important: Our templates provide a solid foundation aligned with Australian WHS practice. However, we have designed them to be customised.

    You must adapt this document to the specific equipment, environment, and risks present in your workplace to ensure it is fit for purpose. Relying on a generic template without customisation may not adequately address your specific safety duties.

    This is a key consideration in any formal compliance review, where a WHS compliance auditing process will examine the suitability of your safety documentation.

    When to Use It

    A VOC for a trailer-mounted generator should be conducted at several key points to ensure ongoing safety and competence. Triggers for conducting a VOC include:

    • Pre-employment: To verify the skills and experience claimed by a new hire.
    • New Equipment: When a new type or model of trailer-mounted generator is introduced to the site.
    • Post-incident: Following an incident or near-miss involving the equipment to identify any competency gaps.
    • Identified Performance Issues: If a supervisor observes unsafe or inefficient operation.
    • Periodic Re-verification: As part of a regular schedule (e.g., every 2-3 years) to ensure skills have not diminished over time.

    This process is distinct from assessing competence on a stationary unit, which is addressed by our Verification of Competency (Diesel Generator) Template.

    Who Should Use It

    This template is intended for use by individuals responsible for workplace safety and operational supervision. This typically includes:

    • Site Supervisors and Foremen
    • Work Health and Safety (WHS) Officers or Advisors
    • Project Managers
    • Training and Assessment Coordinators

    Crucially, the person conducting the assessment must be deemed competent themselves. This means they must possess deep technical knowledge of trailer-mounted generators, understand the relevant hazards and control measures, and have experience in conducting assessments.

    If your organisation lacks this internal expertise, engaging external specialists through WHS consulting services can provide the necessary third-party assurance.

    Key Assessment Criteria

    A thorough VOC should cover all phases of operation. Key areas to assess include:

    Pre-start Checks

    The operator should demonstrate the ability to conduct a comprehensive pre-start inspection, including checking fuel and oil levels, inspecting for leaks, ensuring guards are in place, checking battery condition, and verifying the trailer's roadworthiness (tyres, coupling, lights).

    Safe Operation and Positioning

    This involves observing the operator's ability to safely tow and position the generator on site, considering ground stability, ventilation, and proximity to combustibles. The assessment should also cover correct start-up and shutdown procedures, load management, electrical connection safety (cable management, RCDs), and proper earthing techniques.

    Emergency Procedures

    The operator must be able to articulate and, if simulated, demonstrate the correct response to emergencies. This includes emergency shutdown, procedures for fuel spills, response to fire, and understanding the first aid requirements for electric shock.

    Mobile Plant Competency

    As trailer-mounted generators are mobile, their use often intersects with the operation of other machinery. Ensuring operators are aware of site traffic rules and interaction protocols is vital.

    The assessment can be complemented by checks for other mobile equipment, such as our Verification of Competency (Water Cart) template, to build a holistic view of operator skill.

    You can find this and many other helpful tools in our free WHS resources library, designed to support Australian businesses in managing their safety obligations.

    Common mistakes

    Common mistakes to avoid

    • Using a generic checklist without customising it for the specific generator model and worksite risks.
    • Assigning an assessor who lacks sufficient technical expertise or assessment experience.
    • Treating the VOC as a 'tick-and-flick' exercise rather than a genuine observation of practical skill.
    • Failing to document and file the completed VOC, leaving no record of due diligence.

    Did you know

    Noise Hazard

    Many portable generators operate at levels above 85 decibels (dB(A)), the Australian exposure standard for noise. Prolonged exposure without appropriate hearing protection can lead to permanent hearing loss.

    Carbon Monoxide Risk

    A generator's exhaust contains toxic carbon monoxide (CO), which is colourless and odourless. They must never be used indoors or in poorly ventilated spaces, as CO buildup can be fatal.

    FAQ

    Frequently asked questions

    01What is the difference between a VOC and a license?
    A license confirms an individual has completed the required formal training to a national standard. A VOC verifies that the individual has the current competence to operate a specific piece of equipment safely in a particular workplace environment.
    02How often should a VOC for a trailer-mounted generator be conducted?
    There is no mandated frequency, as it depends on your risk assessment. Common practice is for pre-employment, post-incident, when new equipment is introduced, or as a periodic check every 2-3 years to ensure skills remain current.
    03Can anyone in my company conduct a Verification of Competency?
    No, the assessor must be a competent person. This means they must have the skills, knowledge, and experience with both the specific equipment (trailer-mounted generators) and the process of conducting fair and thorough assessments.
    04Is using this VOC template enough for WHS compliance?
    This template is a tool to help you meet your obligations, not a guarantee of compliance. True compliance is achieved by properly customising the template for your site, implementing it correctly, and integrating it into your overall WHS management system.
