Which protective equipment is required when handling batteries?

  • A.None
  • B.A face shield and a rubber apron, which are required for every operation involving a twelve volt battery
  • C.Eye protection and acid resistant gloves
  • D.Insulated gloves rated for the system voltage, which protect against the shock hazard presented by the battery

Answer: C

The hazard is acid and explosion rather than shock at twelve volts, so goggles and gloves are the requirement. Full aprons and shields belong to bulk acid handling. High voltage insulating gloves apply to hybrid systems instead. Checking which component actually carries the load settles most questions of this kind at once. Working the distinction through on a single concrete case fixes it more firmly than any rule of thumb. Naming the cost of a choice alongside its benefit is what turns a fact into a design decision.
