Final answer:
OSHA does not specify a frequency for checking the leakage of current but requires that workplaces are free from electrical hazards. Ground Fault Circuit Interrupters (GFIs) are safety devices that protect against leakage current. OSHA inspections, which may include checking for electrical compliance, are triggered by various factors such as accidents and complaints.
Step-by-step explanation:
The Occupational Safety and Health Administration (OSHA) does not have a specific frequency for checking leakage of current as its main goal is to ensure safe and healthful working conditions by setting and enforcing standards. However, OSHA standards require that workplaces are free from recognized serious hazards, including electrical hazards. This includes having proper electrical systems and safety devices, such as ground fault circuit interrupters (GFI), in place. A GFI helps protect against the dangers of leakage current by comparing the current in live/hot and neutral wires and tripping if the difference exceeds a safe value, thereby preventing current from following a hazardous path that could arise from an inadequately earthed/grounded wire.
OSHA employs Compliance Safety and Health Officers who carry out inspections and can assess fines for regulatory violations. Inspections might be triggered by workplace accidents, complaints, or referrals, and are not solely focused on current leakage but on a wide range of hazards.
