City Guilds Model Questions Vol1 2017 Engineering Question 26

A workshop performs three tasks: welding, grinding, and chemical cleaning. The hazards are: welding - heat, UV radiation, sparks; grinding - noise, flying particles; chemical cleaning - corrosive fumes and splashes. The safety policy requires that each worker performing all three tasks wear personal protective equipment (PPE) that covers every hazard. The available PPE and their costs are: safety goggles (protects UV and particles) - ₦1500; face shield (protects heat and splashes) - ₦2500; ear plugs (protects noise) - ₦500; respirator (protects fumes) - ₦3000; fire‑resistant gloves (protects heat). Determine the minimum total cost of PPE that a worker must be provided with, expressed as the sum (1500+2500+500+3000+2000).
