o. When loading or un-loading on a public highway, assistants should be used
to hold back traffic. These men should be responsible to the vehicle driver
only.
p. Where the access to and from the site does not have good visibility in all
directions, traffic leaving the site should be controlled by a person nominated
for that purpose.
q. Vehicles should not reverse out of the drilling site onto a public highway.
1.5.3. DRILLING SITE PREPARATORY AND RESTORATION WORKS
a. It is of greatest importance that a proper site appraisal should be made
before any work is commenced. The results, together with any records of
any underground installations, services, workings, etc., should have been
made available to the drilling contractor who in any event should take all
reasonable steps to obtain them.
b. A plan of the site showing the location of hazards to site preparatory work
and to drilling operations should be prepared before any equipment is taken
on site.
c. The drilling contractor should always act with competent engineering advice
and assess the general hazards which may arise during construction and
drilling due to the nature of the ground, the existence of high water, gas or oil
pressures in the strata, surface and underground installations and services.
d. The site should be inspected before rig entry to find a safe approach route to
the proposed drilling position. Some guidance may be required for winching
or lowering rigs on steep slopes and in setting up in marshy or other soft
areas.
e. It should be ascertained that the load bearing quality of the proposed site is
adequate for safe working conditions. Hazardous situations such as old rock
fill, unstable material, surface soils on sloping rock surfaces, under
dangerous banks or quarry sides and on quarry edges should be avoided.
f. A clear access to and from the site should be provided with good visibility in
all directions. If this is not possible, traffic leaving the site should be
controlled by a person nominated for that purpose.
g. The working area should be suitably prepared and where necessary levelled,
surfaced and drained. Means should be provided to trap any escape of
petrol, diesel fuel or oil which might leak into the water courses, fields or
public drains, before it leaves the site.
h. The site should be adequately fenced and warning notices posted, with
separate fencing and warning notices being provided for any mud or slurry
pits.
