Batteries (where present).

1.51

Batteries present a risk if they become damaged by the possible leaking of
electrolyte. This electrolyte is an acid and can cause serious burn injuries. Care
should be taken when working on or near them. NOTE the electrolyte may be in
a liquid or gel form.

1.52

Should you come in to contact with electrolyte you should;

1.53

Remove all clothing contaminated with electrolyte. If you cannot remove then

battery leads are NOT allowed to touch and cause a spark. ALWAYS use suitable
insulated tools.

1.60

Vibrations (where applicable).

1.61

Prolonged use of hand held (operated) machines will cause the user to feel the
effects of/from vibrations. These vibrations can lead to white finger (Raynaud’s

7

MACHINE SPECIFIC SAFETY

phenomenon) or carpal tunnel syndrome. This condition reduces the ability of the
hand to feel and regulate temperature, causing numbness and heat sensations and
may cause never damage and circulatory tissue death.

1.62

Not all factors that lead to white finger disease are known, but cold weather, smoking
and other diseases that affect blood vessels and blood circulation as well as large
and long-lasting impact of shocks are considered factors in the formation of white
finger. Note the following to reduce the risk of white finger and carpal tunnel
syndrome;

1.63

Wear gloves and keep your hands warm.

1.64

Take regular breaks.

1.65

All of the above precautions may help reduce the risk of white finger disease but not
rule out the carpal tunnel syndrome. Long-term and regular users are therefore
recommended to observe the condition of your hands and fingers. Seek medical
attention immediately if any of the above symptoms should occur.

1.70

Noise (where applicable).

hull and create a high risk of explosion.

1.99.1

Carbon monoxide poisoning risk- Never run an engine in a confined space or poorly
ventilated area. Keep the machine away from windows to prevent fumes entering the
internal space. Carbon monoxide is produced by the engine and contained in the
exhaust fumes. You cannot see it or smell it and it can kill you in minutes.

1.99.2

Never use inside a confined space with an exhaust extension. If the exhaust
extension fails the escaping exhaust gases could kill you.
