In an automotive repair facility, technicians encounter distinct mechanical, chemical, and environmental hazards that require specific protective gear. Match each automotive shop task with the most appropriate primary personal protective equipment (PPE).
- Shielded metal arc welding (SMAW) on a steel exhaust assemblyWelding helmet with a shade 10–12 filter lens and heavy split-cowhide gauntlets
- Cleaning and replacing worn friction linings on drum brake assembliesNIOSH-approved particulate respirator (N95 or HEPA-rated)
- Operating pneumatic impact tools and air chisels continuously in an enclosed bayHearing protection (earmuffs or earplugs) with a high Noise Reduction Rating (NRR)
- Flushing a pressurized, hot engine cooling system containing chemical additivesIndirect-vent chemical splash goggles and heat-resistant impermeable rubber gloves
Cevap
Welding exhaust steel requires a shade 10–12 helmet with leather gauntlets; servicing brake friction linings requires a particulate respirator; operating pneumatic impact tools requires hearing protection; flushing hot cooling systems requires chemical splash goggles and impermeable gloves.
Each task is paired with PPE that addresses its distinct hazard: arc welding requires high-shade radiation and burn protection (shade 10–12 helmet and heavy leather gauntlets); brake maintenance requires respiratory filtration against fine dust (NIOSH-approved respirator); pneumatic tool operation requires acoustic attenuation (earmuffs/earplugs with high NRR); and hot coolant maintenance requires protection from pressurized hot fluid splash (indirect-vent goggles and impermeable chemical gloves).
