Occupational safety and health regulations for construction (OSHA 29 CFR 1926)

What the exam tests

OSHA 29 CFR 1926 Subpart K (electrical) and Subpart E (fall protection), plus ladders, scaffolding, PPE, and hazard communication, set the construction safety rules for PV crews. The exam tests thresholds, training, and employer duties.

Core rules

  • Fall protection is required when employees are exposed to falls of 6 ft or more to a lower level, or when working near certain dangerous equipment. Acceptable systems include guardrails, safety nets, and personal fall arrest systems; anchors must support 5,000 lb per worker or be designed by a qualified person.
  • Ladders: maintain a 4:1 angle, extend 3 ft above the landing, secure them, and maintain three points of contact. Do not use the top step.
  • Subpart K requires GFCI protection for temporary receptacles, assured equipment grounding conductor programs where GFCI is not used, lockout/tagout, and proper wiring methods. Only qualified persons may work on electrical circuits.
  • PPE must be provided at no cost to employees, and hazard communication training must cover chemicals such as battery electrolytes and cleaning agents.
  • A competent person must inspect scaffolding, excavations, and fall protection systems; employees must be trained on hazards and controls.

Worked example

A crew installs racking on a 6:12 pitch roof with an eave 8 ft above grade. Because the fall distance exceeds 6 ft, fall protection is required. A guardrail at the eave or a personal fall arrest system with an anchor rated at 5,000 lb per worker would satisfy the requirement; simply telling workers to be careful does not. The employer must also provide training and inspect the system before use.

Traps

  • Using the 4 ft general-industry trigger instead of 6 ft for construction.
  • Treating ladders as exempt from fall protection or setup rules.
  • Assuming PPE is the employee's responsibility to pay for.
  • Forgetting that temporary electrical circuits on construction sites need GFCI or an assured grounding program.
