Firefighters rescue man trapped in trench

Original post made on Oct 18, 2013

A worker is safe after being trapped when a trench collapsed on him Thursday afternoon. The Livermore Pleasanton Fire Department was called to Blakemore Court at about 3:40 p.m. The worker was up to his chest when the trench walls caved in on him.

Sounds like proper shoring was not in place when the trench collapsed. From what it sounds like, the worker was up to his chest when it collapsed which means that shoring was probably required, but missing. The Fire Dept most likely will call Cal/OSHA to investigate.

Does anyone know what they were doing to be in a hole so deep?

"three engines, one truck, two Rescue units, one ambulance, one battalion chief, two deputy fire chiefs and a utility unit responded to the scene."

I would suspect a trench that deep was for a sewer lateral running from the house to the main.

If a ditch is deeper than 5'-0", shoring is required. From the article, you cannot determine how deep the trench was or if shoring was required, since the man could have been on his knees in a 3' deep trench when it caved in. The man was lucky that his chest was not covered, since that is what generally kills, once you exhale, the dirt squeezes your body then you are not allowed to expand your chest to breathe in.
Holes of 5' and deeper are not uncommon, it could have been sewer or water or a foundation, the article is vague. In parts of Livermore, the soil is extremely unstable or "C-60" and the shoring used is different than for soil types A and B, the shoring is required to have sheets of plywood on it to hold up the unstable soil.
It is not uncommon for my company to have ditches or holes open in Livermore in excess of 5'0", we have been as deep as 12-15' on occasion.
We are very glad the worker was not killed and only sustained minor injuries!

In my days in the trenches anything over 3 feet deep had to have shoring on both sides of the trench before anybody climbed down there, hopefully they fine the contractor on this job and make him pay for that large response of manpower that showed up for the rescue, I'm tired of my tax dollars paying for other peoples stupid mistakes. Hello OSHA anybody there ??
