Difficulty: MediumPower Tool Safety and Power Sources

In automotive and vocational shop operations, different power tool energy sources present unique hazards. Match each tool power source type with its corresponding critical safety device or prevention protocol.

  • Corded AC electric power toolGround-Fault Circuit Interrupter (GFCI) to rapidly cut current during line-to-ground leakage
  • Pneumatic (compressed air) toolWhip check safety cable installed across hose couplings to restrain violent line movement
  • Hydraulic shop equipmentCardboard shield used during leak checks to prevent high-pressure fluid injection into tissue
  • Cordless lithium-ion battery toolInspection for casing swelling and cell overheating to prevent hazardous thermal runaway

Answer

Corded AC electric power tool pairs with Ground-Fault Circuit Interrupter (GFCI) protection; Pneumatic tool pairs with Whip check safety cable across couplings; Hydraulic shop equipment pairs with Cardboard shield inspection against fluid injection; Cordless lithium-ion battery tool pairs with Inspection for casing swelling and thermal runaway prevention.
Each shop power source possesses a distinct hazard profile requiring specialized mitigation: corded AC tools require GFCI protection to avert shock from ground faults; pneumatic systems require whip check cables to restrain flailing hoses upon coupling failure; hydraulic machinery demands cardboard shield inspection to prevent severe high-pressure fluid injection; and lithium-ion battery tools require monitoring for swelling and heat to avoid hazardous thermal runaway.

Step-by-Step Solution

1
Analyze the primary hazard and required safety control for corded AC electrical tools.
Electric tools carry the danger of line shock and ground faults, which require fast-acting GFCI interruption and grounding pathways.
Standard utility line voltage poses serious shock hazards if insulation fails or damp conditions are present.
2
Analyze the mechanical energy hazard associated with compressed air hoses and pneumatic tools.
Pneumatic lines under pressure can violently whip if a coupler disconnects, necessitating mechanical whip check safety cables.
Stored compressible gas expands rapidly upon coupling failure, creating dangerous projectile and impact hazards.
3
Analyze the pressure hazard specific to hydraulic fluid lines and rams.
High-pressure hydraulic leaks can pierce skin and inject toxic fluid, requiring non-contact leak detection using cardboard or wood shields.
Hydraulic fluid under thousands of pounds per square inch causes severe subcutaneous tissue trauma if touched directly.
4
Analyze the chemical and thermal hazards of rechargeable cordless battery systems.
Lithium-ion cells that suffer physical or thermal damage can undergo self-sustaining thermal runaway, requiring monitoring for swelling and heat.
Internal cell short circuits can ignite electrolyte material and create intense chemical fires.
