Subpart P Excavations/General Requirements/Protection of Employees from Loose Rock or Soil 1926.651(j)
Pic: East Coast Contractor/City Work---is shoring mandatory? Why? While CP is on point, and other issues are subject to discussion, most compliance officers will only cite for sure the material within 2' feet of the edge. Please analyze or provide comment. Actual depth not verified. Believed 4'10".
As noted, the issue broadly is the hazardous movement of soil.
Soil from the face or sides, or out from under the protective system (there is no 2' rule in the 1972 Subpart P: Excavations and Trenching), sufficient to entrap, immobilize. This is addressed in the definition for cave-in. 1926.650(b)
Then the standard addresses in two paragraphs under the heading as noted earlier, what the prior standard addressed as two separate hazards.
Dangers associated with movement of loose rock or soil from slopes and benches, spillage from swinging buckets and the backfilling of soil or select fill. Abatement is PPE, such as hardhats, scaling of material or barricades or a combination of both as necessary.
Other general requirements also address these hazards, such as the need for a hard hat for the truck, otherwise known as overhead cab protection.
Another would be the issue of undermining as it might occur with sidewalks, pavements, and appurtenance structures.
Then, there remains the prohibition of spoil, materials, or equipment within 2' of the edge. Abatement is relatively simple---remove it!
Why let convenience, laziness, or willful disregard for possible injury play havoc on your jobsite?
As instructors---let's not shortchange this hazard. It is real.
My opinion, and most disagree with me, Competent Person Training for Excavations, cannot be accomplished in a four-hour presentation, which has become the standard to accommodate the contractor.
I know the contractor is a customer, but the training process requires some integrity on the part of the contractor, shoring vendor, and instructor.
In this, most instructors, do not have a choice and that this decision has been taken out of your hands. I wish you well in your efforts to provide effective and comprehensive training in the time you have.
And, if possible, tell them about TEST (Trench Excavation Safety Taskforce). TEST is a grass roots effort to spread the gospel on excavation safety.
Zero fatalities are a worthy goal. Let's not be weary in well-doing.
