Accepted Answer

Question 5

OSHA's electrical safety standard requires that Ground Fault Circuit Interrupters (GFCIs) be used:

Accepted Answer

OSHA 29 CFR 1926.404 requires GFCI protection for all 120-volt, single-phase, 15- and 20-amp receptacles used in construction. Contractors may use an Assured Equipment Grounding Conductor Program (AEGCP) as an alternative.

Question 6

A 'competent person' in OSHA construction standards is someone who:

Accepted Answer

OSHA defines a 'competent person' as one who is capable of identifying hazardous or dangerous conditions in a specific area AND has the authority to take prompt corrective measures. OSHA 30 training alone does not make someone a competent person.

Question 7

Accepted Answer

OSHA's LOTO standard (29 CFR 1910.147) applies to servicing and maintenance activities where unexpected energization (electrical, hydraulic, pneumatic, thermal, gravitational) could cause injury. It does not cover normal construction operations.

Question 9

An OSHA recordable injury or illness must be recorded on the OSHA 300 log if it results in:

Accepted Answer

An injury or illness is OSHA recordable if it results in death, days away from work, restricted work or job transfer, medical treatment beyond first aid, loss of consciousness, or a significant injury diagnosed by a healthcare professional.

Question 10

The OSHA 'Fatal Four' in construction — the four hazards responsible for the most worker deaths — are:

Accepted Answer

OSHA's 'Fatal Four' are the leading causes of construction worker deaths: Falls (~38%), Struck-by (~10%), Caught-in/between (~2%), and Electrocution (~9%). Eliminating these hazards would save over 600 lives per year.
