#54. A safety rule states: ‘Use ground-fault protection for receptacles on construction sites.’ What is required?

Use only two-prong receptacles

Disable GFCI devices to prevent nuisance trips

Rely on extension cords for protection

Protect receptacle circuits with GFCI or equivalent devices

#55. A checklist item reads: ‘Verify that all covers and guards are replaced after work is completed.’ What should be confirmed?

All equipment covers and guards are reinstalled before leaving

Covers are removed to allow easier access
