long term health problems such as brain damage.
The symptoms of carbon monoxide poisoning can
include but are not limited to the following;
Headaches, dizziness, nausea, breathlessness,
collapsing or loss of consciousness.
Carbon monoxide poisoning symptoms are similar to
flu, food poisoning, viral infections and simply
tiredness. It is quite common for people to mistake this very dangerous poisoning for something else.

has been repaired by an electrically competent person.
All trailing cables should be routed so as not to cause any kind of trip hazard.
NEVER work on or near electricity with wet hands, wet clothing, and wet gloves.
Batteries (where present).
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 liquid or gel form.
Should you come into contact with electrolyte you should;
Remove all clothing contaminated with electrolyte. If you cannot remove then saturate in water.
Get medical assistance as soon as possible. You must advise the medical staff of the type acid.
Lead/acid battery = dilute sulphuric acid
Nickel/cadmium = potassium hydroxide alkali electrolyte.
Use fresh running water to wash off excess electrolyte, continue this until medical assistance arrives.
Make sure that you do not wash the electrolyte to another part of the face or body.
If electrolyte comes into contact with Eyes the electrolyte needs to be immediately washed away with
large amounts of water. Make sure that you do not wash the electrolyte to another part of the face or
body.
Gasses from charging batteries are highly flammable and great care should be taken to charge in well
ventilated areas.
There is an explosion risk if the battery terminals are short circuited, when connecting/dis-connecting
ALWAYS exercise great care so that the terminals or battery leads are NOT allowed to touch and cause
a spark. ALWAYS use suitable insulated tools.

Vibrations (where applicable).
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 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 nerve damage and circulatory tissue death.
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
the white finger and carpal tunnel syndrome:
Wear gloves and keep your hands warm
Take regular breaks
All of the above precautions may help reduce the risk of white finger disease but not rule out 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.
Noise (where applicable).
The operating noise of the machine can damage your hearing. Wear hearing protection such as
earplugs or ear defenders to protect your hearing. Long- term and regular users are advised to have
hearing checked regularly. Be especially vigilant and cautious when wearing hearing protection
because your ability to hear alarm warnings will be reduced.
Noise emissions for this equipment is unavoidable. Carry out noisy work at approved times and for
certain periods. Limit the working time to a minimum. For your personal protection and protection of
people working nearby it is also advisable for them to wear hearing protection.
See CERTIFICATE of CONFORMITY section for outdoor noise declaration of conformity.
