Safety Procedures & PPE Flashcards

Before charging an Audi e-tron's high-voltage battery in the shop, why must the charging area be well-ventilated?

Answer: To dissipate hydrogen gas that can be released during charging and prevent explosive accumulation

Lithium-ion batteries can release hydrogen and other flammable gases during charging, making ventilation critical to prevent explosive concentration.

A technician must weld near Audi fuel lines. What preliminary step is MANDATORY?

Answer: Drain and purge the fuel system, then shield lines with a non-flammable barrier

Fuel vapors are highly flammable; the system must be drained, purged, and protected with non-flammable shielding before any welding or grinding near fuel components.

What does a green-tagged tool in a properly maintained Audi workshop inspection program typically indicate?

Answer: The tool has passed its most recent safety inspection and is approved for use

Color-coded tagging systems (green = safe) communicate at a glance whether a tool has cleared its last safety and calibration inspection.

Which chemical commonly found in Audi brake cleaner products is classified as a potential carcinogen and requires ventilation or respiratory protection?

Answer: Tetrachloroethylene (PERC) or similar chlorinated solvents

Tetrachloroethylene and other chlorinated solvents in brake cleaners are classified as probable or possible carcinogens and require ventilation or vapor-rated respirators.

When an Audi airbag module is removed and stored, what is the correct positioning to minimize deployment injury risk?

Answer: Cushion face up in a designated container away from heat sources

Airbag modules must be stored cushion-side up in a designated container away from heat to prevent accidental deployment that could cause serious injury.

What is the required action if an Audi technician sustains a cut from a sharp sheet metal edge and the bleeding does not stop within a few minutes?

Answer: Seek immediate first aid or medical attention and report the injury per shop protocol

Persistent bleeding requires proper first aid or medical evaluation, and all workplace injuries must be reported per OSHA recording requirements and shop safety protocol.

Which PPE combination is required when using a high-pressure washer to clean an Audi engine bay?

Answer: Safety glasses or face shield, waterproof gloves, and waterproof apron/boots

High-pressure water can inject grease and fluid into skin and eyes; a face shield, waterproof gloves, and protective footwear are essential to prevent injuries.
