i. Where working platforms are required to support men, equipment and/or
materials, the platform should be properly constructed. It should be of
adequate dimensions, and if over 2 metres above ground, should have guard
rails and tow boards so placed as to prevent falls of persons or articles from
the platform. Similar guard rails and tow boards may be considered
desirable on platforms constructed at lesser heights in some circumstances.
The platform construction and stability should be checked weekly for defects.
1.5.4 SETTING UP
a. The site must be kept in a well organised tidy state and clear of all debris and
extraneous material.
b. It is preferable for acoustic barriers to be constructed of non-flammable
material.
c. It should be ensured that all relevant machine guards have been installed
before starting up any machine.
d. Bulk stocks of fuel, oil and gas cylinders should be stored in a designated
compound remote from the immediate working area.
e. Rods, Casings etc. should be neatly stacked, preferably on appropriate racks
and maintained in a clean condition.
f. Threads and connectors should be regularly cleaned and greased, and
preferably protected with thread protectors.
g. Tools and materials should be laid out according to requirements and in
order of use.
1.5.5 DRILLING OPERATIONS - GENERAL
a. Drilling may entail the employment of some personnel inexperienced in this
class of work. In such circumstances, particular care should be taken to
explain and enforce safety precautions, and teach practice in the handling
and use of equipment. It is important that safe working systems of work are
adhered to by all personnel.
b. Inexperienced men should always remain under expert supervision.
c. At the commencement of each shift the incoming crew should make certain
that the equipment is in a useable and safe condition. Unsafe conditions and
any significant change in operating conditions should be reported in the
driller’s log book and any action taken thereon should also be logged.
d. Each operation must have its set routine, each team member knowing
exactly what part he is to play.
e. Under no circumstances must a rig be operated by one man.
