1.3 Hydrogen and Carbon Dioxide Warning
Applicable for furnaces constructed to use H2and CO2test gases with CO2'Purge' gas.
H2can form explosive gas mixtures, take precautions to avoid leakage
of H2.
H2and CO2can react to form CO.
see section 1.2.
Carbon dioxide (CO2) is a colourless, odourless and tasteless gas that is an asphyxiant.
Rapid unconsciousness occurs at levels above 11%, levels of 20 - 30% are immediately
hazardous to life.
Information extracted from Croner Publications Ltd. Substances Hazardous To
Health.
To minimise the risks associated with CO2it is most important that the product is
installed and operated in accordance with this instruction manual. If the product
operator experiences any of the effects listed above, the product must be isolated from
the gas and electricity supplies immediately and expert advice sought. For safety
guidelines seek the gas manufacturers advice.
1.4 Safety Warning - Refractory Fibre Insulation
Insulation made from High Temperature Insulation Wool
Refractory Ceramic Fibre, better known as (Alumina silicate
wool - ASW).
This product contains alumino silicate wool products in its thermal insulation. These
materials may be in the form of blanket or felt, formed board or shapes, slab or loose
fill wool.
Typical use does not result in any significant level of airborne dust from these materials,
but much higher levels may be encountered during maintenance or repair.
Whilst there is no evidence of any long term health hazards, it is strongly recommended
that safety precautions are taken whenever the materials are handled.
Exposure to fibre dust may cause respiratory disease.
When handling the material, always use approved respiratory protection
equipment (RPE-eg. FFP3), eye protection, gloves and long sleeved clothing.
Avoid breaking up waste material. Dispose of waste in sealed containers.
After handling, rinse exposed skin with water before washing gently with soap
(not detergent). Wash work clothing separately.
Before commencing any major repairs it is recommended to make reference to the
European Association representing the High Temperature Insulation Wool industry
(www.ecfia.eu).
