1.5.7 DRILLING AND THE USE OF COMPRESSED AIR
a. Compressors should be set up on level ground so that internal lubrication is
not adversely affected and proper loading is put on bearings.
b. Compressors should preferably be sited up-wind from the rig in order to
prevent dust contamination. However, when associated with the drilling of
large diameter holes siting should be such as to also avoid exhaust fumes
entering the borehole.
c. The parking brake should be applied or the wheels chocked in order to
prevent vibration moving the vehicle.
d. Internal combustion engines should be fitted with spark arrestors.
e. A daily check should be made on oil, fuel and water levels and on engine and
compressor air cleaner oil levels.
f. A daily check should be made of all compressed air hoses, clips and
couplings.
g. Compressors should not be operated with the engine covers open or with the
fuel caps removed.
h. Condensate should be drained from the compressor, oil cooler and control
filter, a check made that all controls are in neutral gear, and that all
connected equipment is turned off before starting up.
