That question has an answer that fills books. In a VERY brief answer, to have checked for underground hazards (wires, pipes) BEFORE starting to excavate, check for overhead hazards (powerlines) before starting, check for surface encumbrances (buildings, boulders, trees) that could be affected by the excavation- BEFORE starting. If a worker will enter an excavation more than 3 feet deep, a COMPETENT PERSON must inspect the excavation for hazards. The excavation must be protected from traffic, and from collapse. This is normally done by sloping, shoring or shielding.
The safe way to enter a deep excavation is to follow proper safety protocols, such as using a ladder or properly sloped access ramp, ensuring proper shoring or support systems are in place, and having a spotter or standby person outside the excavation. Workers should be trained on excavation safety and have appropriate personal protective equipment.
Yes. In expert hand it is safe procedure.
It should only be done if your vision is so impaired that there's no other choice. It is a relatively safe procedure, but it's not 100 % safe (no procedure is).
safe isolation 3 phase
it is very safe if you use the correct security procedure!
Echocardiography is an extremely safe procedure and no special precautions are required
manual excavation
The suffix of "excavation" is "-tion".
The abbreviation for "excavation" is "excav."
Excavations should be battened back or stepped when the vertical face of the excavation exceeds a safe slope angle, typically 1:1 (45 degrees). This helps prevent collapses, cave-ins, and injuries. Battering or stepping the excavation face provides better stability, reducing the risk of accidents.
Properly identify and mark underground utilities before excavating. Use safe digging practices, such as hand digging or hydro excavation. Ensure all workers have appropriate training and follow safety protocols. Monitor the excavation site for any signs of potential hazards, such as cave-ins or gas leaks.
