This week’s Absolute Shocker - trenching! The trench shield should extend above ground level so it will:
provide engulfment protection (note the trench wall above the shield)
allow back filling to the side of the shield (safe access to the shield and if a ladder is secured to it, safe access to the trench)
work as fall protection (if the shield is 900mm out of the ground, otherwise edge protection will need to be fitted to the shield).
Some other issues include:
the pump being too close to the unprotected trench edge with the;
risk of a worker falling into the trench while accessing the pump
risk of the pump falling into and onto someone in the trench
the fence ground anchor suspended above the shield edge
lack of traffic management on the road.
Never take shortcuts with trench safety.
