Under Cal/OSHA regulations, what is required when a construction site has a trench excavation deeper than 5 feet?
Correct Answer
D) A competent person must inspect the excavation daily
Cal/OSHA requires that excavations 5 feet or deeper be inspected daily by a competent person who can identify hazardous conditions and has authority to take corrective action. This is more stringent than basic safety equipment requirements.
Why This Is the Correct Answer
Cal/OSHA regulations specifically require that excavations 5 feet or deeper must be inspected daily by a competent person. This competent person must be trained to identify existing and predictable hazards and have the authority to take prompt corrective measures to eliminate them. The daily inspection requirement is a critical safety protocol that goes beyond basic PPE or training requirements, ensuring ongoing hazard assessment and worker protection in deep excavations.
Why the Other Options Are Wrong
Option A: Workers must wear hard hats and safety vests
While hard hats and safety vests are important general safety equipment on construction sites, they are not the specific Cal/OSHA requirement for deep trench excavations. The regulation focuses on inspection protocols rather than just personal protective equipment for trenches deeper than 5 feet.
Option B: A safety meeting must be held weekly
Weekly safety meetings are good practice but not the specific Cal/OSHA requirement for deep excavations. The regulation mandates daily inspection by a competent person, which is more frequent and specific than weekly meetings. Daily inspection addresses the immediate and changing hazards in excavation work.
Option C: Only safety training for workers
Safety training alone is insufficient for deep excavation requirements. While worker training is important, Cal/OSHA specifically requires ongoing daily inspection by a competent person who can identify hazards and take corrective action. Training is a one-time or periodic requirement, not the daily safety protocol mandated for deep excavations.
Memory Technique
Remember 'DEEP 5 DAILY': Deep excavations (5+ feet) require Daily inspection by a competent person. The alliteration helps recall that deeper trenches need daily attention.
