AUDI Safety Procedures & PPE 3 — Questions and Answers
Question 1: Which OSHA regulation governs Lockout/Tagout (LOTO) procedures in an automotive service facility?
- 29 CFR 1910.147 (Correct answer)
- 29 CFR 1910.132
- 49 CFR 571.108
- NFPA 70E Article 120
Correct answer: 29 CFR 1910.147
OSHA 29 CFR 1910.147 (Control of Hazardous Energy) establishes LOTO requirements to prevent unexpected energization of machinery during service.
Question 2: What is the minimum recommended eye protection rating (ANSI standard) for safety glasses used in an Audi shop?
- ANSI Z41
- ANSI Z87.1 (Correct answer)
- ANSI Z89.1
- ANSI Z49.1
Correct answer: ANSI Z87.1
ANSI Z87.1 is the American National Standard for occupational and educational eye and face protection devices used in automotive workshops.
Question 3: A technician is draining engine oil from an Audi. Which PPE is MOST important to prevent chemical burns from hot oil?
- Steel-toed boots only
- Nitrile gloves and safety glasses (Correct answer)
- A hard hat and hearing protection
- A dust mask and cotton gloves
Correct answer: Nitrile gloves and safety glasses
Hot engine oil can cause thermal and chemical burns, making nitrile gloves and safety glasses the essential PPE to protect hands and eyes during drainage.
Question 4: What hazard does an Audi hybrid or EV orange high-voltage cable specifically indicate?
- Coolant lines under pressure
- High-voltage DC or AC electrical conductors (Correct answer)
- Fuel vapor lines
- CAN bus communication wiring
Correct answer: High-voltage DC or AC electrical conductors
Orange high-voltage cables in Audi hybrids and EVs mark conductors carrying dangerous high-voltage electricity (typically 400V DC or higher).
Question 5: When lifting an Audi A4 (B9) on a two-post lift, where should the lift arms contact the vehicle?
- Anywhere along the rocker panel
- At the reinforced pinch-weld lift points specified in the owner's manual (Correct answer)
- Under the floor pan center tunnel
- On the lower control arms
Correct answer: At the reinforced pinch-weld lift points specified in the owner's manual
Audi specifies reinforced pinch-weld lift points to distribute the vehicle's weight safely without damaging body panels or underbody components.
Question 6: Which fire class applies to a flammable solvent fire in an Audi workshop, and which extinguisher type should be used?
- Class A – water extinguisher
- Class B – CO2 or dry chemical extinguisher (Correct answer)
- Class C – halon extinguisher
- Class D – dry powder extinguisher
Correct answer: Class B – CO2 or dry chemical extinguisher
Flammable solvents are Class B fires; CO2 or ABC dry chemical extinguishers smother the fire without spreading the burning liquid.
Question 7: What is the purpose of wearing hearing protection rated at NRR 25 or higher when using an Audi shop's pneumatic impact wrench?
- To reduce communication distractions
- To prevent noise-induced hearing loss from sustained high-decibel tool operation (Correct answer)
- Impact wrenches are below OSHA noise thresholds
- To meet aesthetic dress-code requirements
Correct answer: To prevent noise-induced hearing loss from sustained high-decibel tool operation
Pneumatic impact wrenches often exceed 100 dB; sustained exposure above 85 dB (OSHA action level) causes irreversible noise-induced hearing loss without adequate protection.
