Safety and OSHA Regulations Flashcards

What is the OSHA requirement for a 'competent person' on a construction excavation?

Answer: A person capable of identifying hazards and authorized to take corrective measures must be present at all excavations

OSHA 29 CFR 1926.650 requires a competent person to classify soil, inspect excavations daily, and address hazards before workers enter.

What is a 'confined space' and when does OSHA require a permit to enter one?

Answer: A space large enough for a worker but not designed for continuous occupancy — a permit is required when it has serious hazards

A permit-required confined space has actual or potential hazards (atmospheric, engulfment, or entrapment) requiring permits, atmospheric testing, and rescue plans.

Under OSHA 10/30-hour training, what does the '10' and '30' refer to?

Answer: The number of training hours required — 10-hour for workers and 30-hour for supervisors

OSHA 10-hour training is designed for entry-level workers, while the 30-hour course is intended for supervisors and safety managers who need broader hazard knowledge.

What is 'lockout/tagout' (LOTO) as required by OSHA?

Answer: A procedure to de-energize and lock equipment before maintenance to prevent accidental startup

LOTO procedures prevent workers from being injured by the unexpected energization or startup of equipment during servicing.

What does OSHA require regarding electrical safety for construction workers under 29 CFR 1926 Subpart K?

Answer: Proper grounding, GFCIs on temporary power, and safe clearance distances from live lines

OSHA requires ground fault circuit interrupter (GFCI) protection on temporary power, proper grounding, and maintaining safe approach distances to overhead power lines.

What is the OSHA-required minimum width for scaffolding platforms used by construction workers?

Answer: 18 inches minimum

OSHA's 29 CFR 1926.452 requires scaffold platforms to be at least 18 inches wide to provide sufficient working space and reduce fall risk.
