exposed hands
are susceptible to physical, chemical and other hazards. According to
the Construction Safety Association of Ontario, hand protection is often
the only practical means of preventing injury from the following:
• Physical hazards, sharp or jagged edges on materials
and tools, heat, vibration;
• Corrosive or toxic chemicals;
• Ultraviolet radiation.
For physical hazards such as sharp edges, splinters, and
heat, leather gloves are preferred. Cotton or other materials do not
stand up well and are recommended only for light-duty jobs.
Vibration transferred from tools and equipment can
affect hands and arms. One result may be hand/arm vibration syndrome
(HAVS). This disease causes the following changes in fingers and
hands:
• Circulation problems such as whitening or bluish
discoloration, especially after exposure to cold;
• Sensory problems such as numbness and tingling;
• Musculoskeletal problems such as difficulty with fine
motor movements.
Workers who use vibrating tools such as jackhammers,
grinders, riveters, and compactors on a daily basis may develop HAVS.
Preventing this disease requires cooperation between employers and
workers.
Employers can do the following to prevent injury:
• Provide power tools with built-in vibration-reducing
components;
• Review exposure
times and
allow rest breaks away from vibrating tools;
• Ensure proper tool maintenance (worn grinding wheels
or tool bearings can lead to higher vibration levels);
• Train exposed workers in prevention techniques;
• Provide anti-vibration gloves.
Workers should consider the following:
• Wear appropriate clothing in cooler
weather to
maintain core body temperature;
• Wear gloves whenever possible;
• Wear anti-vibration gloves when using power tools and
equipment;
• Avoid smoking (smoking contributes to circulatory
problems);
• Report any poorly functioning tools immediately.
For protection against chemical hazards, the material
safety data sheet
(MSDS) for the
product being used should identify whether gloves are needed and what
they should be made of; MSDSs must be available on site for all
controlled products being used.
Construction workers may find themselves exposed to
pinch point hazards via the equipment they use and may have to maintain.
The Ohio State University Extension offers the following information on
what types of gloves to wear, and how to protect fingers and hands from
pinch points:
• Identify the pinch points on mechanically moved loads,
lowered loads and metal drums. Pinch points are created when two objects
move together, with at least one of them moving in a circle.
• Know when to wear gloves. Gloves should be worn when
exposed to hazards that cause cuts, scrapes and chemical burns or
injuries. Do not wear gloves around reciprocating or rotating machine
parts.
• Allow rotating parts to come to a stop before working
on them.
• Use a tapered punch or other appropriate tool to align
the holes in parts.
• Rings should not be worn when operating or repairing
machinery.
• Remove fuses with fuse removers, not fingers.
• Do not test the temperatures of gases, liquids, or
solids with hands. Reflex damage can occur immediately.
• Keep grinder tool rests adjusted to 1/8 inch gap or
less.
• Handle sharp or pointed tools (hatchets, chisels,
punches, awls, knives, pitch forks and machine blades) carefully.
• Perform maintenance only when tools or machinery are
not in operation.
• If guards are removed to perform maintenance, replace
them immediately after servicing.
