Knowledge of Health, Safety and Good Housekeeping in the Automotive Environment
This subtopic establishes the critical health, safety, and housekeeping protocols essential for vehicle accident repair environments. Learners must demonstrate understanding of selecting and using personal protective equipment tailored to body repair tasks, such as respiratory protection against isocyanate paints and eye protection during welding. Effective housekeeping practices are emphasised to prevent slips, trips, and fire hazards from accumulated body filler dust and waste materials, ensuring a safe and compliant workshop.

Quick Revision Summary (Key Takeaway)
The IMI Level 2 Diploma in Vehicle Accident Repair Mechanical, Electrical and Trim (MET) Principles covers the safe and systematic removal, repair, and replacement of mechanical, electrical, and trim components on accident-damaged vehicles. It includes health and safety, tools and equipment, vehicle systems, and the importance of following manufacturer specifications and industry standards.
Topic Overview
The MET principles module is a core part of the IMI Level 2 Diploma, focusing on the mechanical, electrical, and trim aspects of vehicle accident repair. It equips students with the knowledge and skills to safely remove, repair, and replace components that are not part of the body shell but are essential for the vehicle's operation. This includes engines, gearboxes, cooling systems, airbags, wiring looms, and interior trim.
This module is crucial because modern vehicles are highly complex, with integrated safety systems and advanced materials. A MET technician must understand how these systems interact and how to work on them without causing further damage or compromising safety. The principles learned here are applied in real-world repair shops, where precision and adherence to manufacturer specifications are paramount.
The module also emphasizes health and safety, environmental regulations, and the use of specialist tools and equipment. By mastering these principles, students build a foundation for further qualifications and a career in the vehicle repair industry, where MET skills are in high demand.

Learning Objectives
What you need to know and understand
- understand the correct personal and vehicle protective equipment to be used within the automotive environment, understand effective housekeeping practices in the automotive environment, understand key health and safety requirements relevant to the automotive environment, understand about hazards and potential risks relevant to the automotive environment, understand personal responsibilities
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating correct selection and use of personal protective equipment (PPE) specific to tasks, e.g., air-fed respirators for spraying 2K paints and welding gauntlets for MIG welding.
- Credit given for explaining effective housekeeping routines, including immediate clean-up of body filler dust, disposal of contaminated wipes in fire-resistant bins, and safe storage of flammable solvents.
- Expect evidence of understanding vehicle protective equipment (VPE) usage, such as seat covers, wing protectors, and masking materials to prevent damage during repairs.
- Assess ability to identify key health and safety regulations (e.g., COSHH, PUWER) and apply them through control measures like local exhaust ventilation for dust and fume extraction.
Assessment Guidance
Guidance for achieving higher grades
- 💡In written assessments, explicitly link control measures to the hierarchy of control (elimination, substitution, engineering controls, administrative controls, PPE) to demonstrate deeper understanding.
- 💡During practical observations, verbally state your intention to check and don the correct PPE before starting any task, and explain why each item is selected based on the task risk assessment.
- 💡For housekeeping questions, mention the ‘clean as you go’ principle and give examples of good practice such as using dust extraction on power tools and wet wiping surfaces to suppress dust.
- 💡Always refer to manufacturer data and quote specific values (e.g., torque settings, fluid capacities) in your answers to show depth of knowledge.
- 💡Use correct technical terminology, such as 'isolate', 'depressurise', 'calibrated', and 'specification', to demonstrate professionalism.
- 💡In practical assessments, always demonstrate safe working practices, including the use of PPE and correct tool selection, as these are heavily weighted in marking.
Common Mistakes
Common errors to avoid in your coursework
- Learners often confuse the level of respiratory protection needed: using a simple dust mask instead of a fitted FFP3 or air-fed respirator when sanding fillers or spraying paints containing hazardous substances.
- Failing to appreciate that even minor dust from sanding body filler can be combustible, leading to neglect of regular housekeeping and dangerous accumulation in corners and on equipment.
- Underestimating the importance of VPE, resulting in damage to customer vehicles from sparks, overspray, or accidental contact with tools, which constitutes poor workmanship and customer dissatisfaction.
- Believing that generic workshop safety is sufficient, without recognising specific risks unique to body repair, such as welding fume carcinogens and the need for dedicated extraction.
- Misconception: You can use any oil or fluid as long as it's the same type. Correction: Always use the exact grade and specification recommended by the manufacturer, as using the wrong one can cause damage.
- Misconception: Airbags are safe to handle once the battery is disconnected. Correction: Airbags have a backup power supply and can deploy even after battery disconnection; you must wait for the capacitor to discharge and follow specific procedures.
- Misconception: Torque settings are not critical for all bolts. Correction: Many bolts, especially those on safety-critical components like brakes and suspension, require precise torque to ensure proper clamping force and prevent failure.
