Workplace Safety & Personal Protective Equipment
Why Shop Safety Matters
An automotive service shop contains dozens of hazards every day - moving vehicles, high-voltage systems, hot exhaust components, pressurized fluids, and hazardous chemicals. The Red Seal exam tests your understanding of how to work safely and protect yourself, your coworkers, and your customers.
The most important safety principle in the shop is prevention. Wearing the correct personal protective equipment (PPE) and following established procedures prevents the vast majority of injuries.
Exam Fact
Safety glasses must be worn at all times when in the work area - not just during grinding or welding. This is a common exam question.
Personal Protective Equipment Requirements
Every technician needs the right PPE for the task at hand. The basics include:
- Safety glasses - worn at all times in the shop work area
- Hearing protection - required when using air tools, grinders, or working near running engines for extended periods
- Steel-toed boots - protect feet from dropped parts and tools
- Nitrile or chemical-resistant gloves - protect skin from solvents, oils, and brake dust
- Insulated gloves rated for high voltage - required when working on hybrid vehicles or any system carrying more than 50 volts
Always Required
Safety glasses - in the work area at all times
Steel-toed boots - standard shop footwear
Close-fitting clothing - no loose sleeves or jewelry
Task-Specific PPE
Insulated gloves - hybrid/EV high-voltage work
Welding helmet - any welding operation
Respirator - brake dust, paint, chemical exposure
Working on Hybrid Vehicles
When working with hybrid vehicles, the single most critical safety precaution is to disable the high-voltage system and wear insulated gloves. Hybrid and EV batteries operate at 200-400+ volts DC, which is lethal. You must follow the manufacturer's service disconnect procedure before touching any orange-colored high-voltage cable.
Vehicle Lifting Safety
The purpose of jack stands is to safely support the vehicle and prevent it from falling. Never work under a vehicle supported only by a hydraulic jack - jacks can fail. Always place jack stands on the manufacturer-specified lift points before going under the vehicle.
Safety glasses are required at all times in the work area. When working on hybrid vehicles, always disable the high-voltage system and wear insulated gloves rated for the voltage present.
