Construction Safety and Risk Management: Controls, Triggers, and Response

Construction Safety and Risk Management tests OSHA-based field safety and the formal treatment of project risk. Questions often ask for the first control, the competent-person duty, the trigger threshold, or the best risk response.

Safety program

  • Use the hierarchy of controls: elimination, substitution, engineering controls, administrative controls, then PPE. PPE is the last line, not the first.
  • A job hazard analysis breaks work into steps, identifies hazards, and defines controls before work starts.
  • A competent person is designated by the employer and can identify hazards and take prompt corrective action.
  • Key construction triggers: fall protection at 6 feet for general construction; scaffolding fall protection at 10 feet; excavation protective systems at 5 feet or deeper unless the competent person determines stable rock; spoil and equipment at least 2 feet from the excavation edge; a ladder or ramp for trench access within 25 feet of lateral travel.
  • OSHA recordkeeping: report a fatality within 8 hours and an in-patient hospitalization, amputation, or loss of an eye within 24 hours.

Risk management

  • Build a risk register with probability, impact, owner, and response.
  • Responses: avoid, reduce, transfer, accept. Insurance and bonds transfer financial consequences, not physical control.
  • Monitor triggers and update the register as work changes.

Worked example

A 6-foot-deep trench has no protective system, spoil piled 3 feet from the edge, and the nearest ladder 40 feet away. The protective-system trigger is 5 feet, so a trench box, shielding, sloping, or benching is required. The spoil violates the 2-foot minimum. Access violates the 25-foot rule. Correct response: stop work, keep workers out, have the competent person inspect, install the protective system, relocate spoil, and provide access before re-entry.

Traps

Choosing PPE first; treating competent person as a job title rather than a designation; confusing the 4-foot, 5-foot, 6-foot, and 10-foot triggers; assuming a trench box eliminates the need for inspection; and treating insurance as a safety control.
