2.) Possible risks when working with core drilling equipment
2.1 Statics of building construction
Before starting operation let a specialist check whether the borehole(s) intended to be made are a
risk for the statics of the building. Only realise the jobs if they have no influence on the statics of
the construction.
2.2 Fastening
If the drilling stand is fastened insufficiently, the possibility that somebody becomes insured
through the falling down of the drilling stand or rotation around the drilling axle is high.
So it is very important to watch the instructions for installation exactly.
2.3 Electric wires
Ensure yourself that no life wires are around the place where
the borehole shall be made. If you cannot exclude this let an electrician put your equipment to
earth as protection.
Ensure that your equipment is protected by an earth leakage circuit breaker.
Always wear shoes with rubber bottom!
2.4 Power failure
If you use a vacuum pump for the fastening of the core drilling equipment place it where you can
continuously watch the vacuum gauge during operation.
Immediately switch off the drilling drive when the vacuum pressure falls below 0,7 bar because
of a power failure or some other defect and make sure that the core drilling equipment cannot fall
down.
In case of a power failure switch off any electric equipment to prevent accidents in case the
machine starts again suddenly.
2.5 Loose bolted connections
Before starting operation make sure that all bolted connections are tightened. Loose parts can
result in accidents!
