Excavation

Safety Talks for EXCAVATION

출처:nipgroup.com

Before Excavation Review

• Underground utilities located? (Checked with Owning area representative)
• Any overhead hazards? (i.e., falling rock, soil, or other materials or equipment)
• Wiil there be any heavy equipment operating in the near proximity of the excavation?
• Estimated depth required for the excavation?
• How many people will work inside the excavation?
• Is there an escape plan for those inside the excavation to cover a possible cave in or slide?
• Has there been a soil analysis? This will help determine the type of shoring to provide or the angle or repose needed.

Steps to Take to Provide a Safe Excavation

• Any excavation with a depth of four feet or more required adequate shoring or sloping
• Never store excavated or other materials closer than two feet from the edge of the excavation
• Inspect the excavation daily. This must be done by a competent peron
• Access ladders must be provided every twenty-five foot in excavations of four (4) foot or more in depth
• Review escape procedures with all personnel who may have cause to be in the excavation

 

Additional Discussion Notes

• Possible gas accumulation in the excavation?
• Barriers, guardrails or other safety warnings in excavation area?

Remember:  Unlike most accidents, the cave-in of an excavation usually can be predicted if closely watched. It is, therefore, critical that a competent person keeps a close eye on any excavation. Everyone should be removed from the excavation area should it appear to be unstable.
