Re: excavation

[Subject Prev][Subject Next][Thread Prev][Thread Next]
There is no "OSHA permit" in California. The Contractor self certifies and must have a "responsible person" (usually the foreman or superintendent) continuously on site to monitor the excavation. CalOSHA does random inspections to see if their rules are being followed. If you have questions, they also have pretty good tech support staff to answer your questions about how to comply with their regs. You can have a geotech provide recommendations, but make sure their E&O insurance will cover any losses like dead workers from trench collapses. Less liability will probably result if you simply follow the CalOSHA rules.

I wonder what the procedure is for getting an OSHA permit and how long it
takes.
