o. Rig personnel should wear only close-fitting clothing, preferably distinctly
coloured overalls. Clothing should be kept clean by frequent washing, and
each crew member should have a clean change of work clothes on location
at all times. Particular care should be taken to ensure that drawstrings to
hoods or other items of clothing are not left dangling so as to become
entangled in any moving parts.
p. If overalls are not worn, long-sleeved shirts with tails tucked in will provide
protection against sunburn, insect bites, scratches, hazardous chemicals and
flash burns.
q. Safety helmets must be worn by members of the drilling crew and visitors to
the site. Safety boots or safety wellingtons should also be worn.
r. When working on or adjacent to the public highway, a top coat, jerkin or
waistcoat, with fluorescent markings must be worn at all times.
s. The use of gloves whenever practicable is recommended. Gloves prevent
minor injuries when employees are handling rough materials or skin irritants.
Only short, tight fitting gloves should be worn. Gauntlets may become caught
in the machinery and workers may be pulled into moving machinery if they
wear them.
t. Hairnets should be worn by persons with dangerously long hair. Loose
clothing, i.e. trailing scarves, ties etc. should be avoided, especially when
working near rotating machinery.
u. Rig personnel should never wear finger rings or bracelets while working.
v. Eye protection is of the utmost importance. An eye injury, no matter how
slight, should receive prompt medical attention. Even a slight eye injury may
lead to serious complications.
w. The correct eye protection should be provided and should be maintained in
good condition on each drilling site. Employees should wear approved safety
glasses or goggles when chipping, grinding, scraping, buffing, breaking or
cutting any metal or material that involves a flying chip hazard.
x. Operators who wear contact lenses should wear eye protection and should
always be aware of the problems posed by contact lenses when attempting
prompt emergency treatment following the introduction of foreign material
into the eye.
y. Splash proof chemical goggles or face-shields should be used when handling
potentially hazardous or injurious chemical liquids, powders or vapours such
as cement, chemicals, chemical cleaning solutions, creosoted material,
molten metal, asphalt or bitumastic compounds. Goggles also should be
worn by persons near operations which require the use of safety goggles by
the operator.
