1.2 Carbon Monoxide Warning
Operation of the CAF furnace involves the use of carbon monoxide.
Carbon monoxide is a product of reaction of H
2
and CO
2
.
Carbon monoxide (CO) is a colourless, odourless, tasteless and inflammable gas which
is acutely toxic. CO is introduced into the blood stream through the lungs and binds with
the haemoglobin preventing it from carrying oxygen around the body. This can result in
rapid damage to body tissues due to oxygen starvation. Since CO is an accumulating
toxin it can be dangerous even when present in quite low concentrations over long
periods of time. Individuals vary considerably in their reactions to concentrations of
toxic gases; table 1 shows the typical effects of cumulative CO exposure.
Information extracted from Guidance Note EH43 (1996) from the Health and
Safety Executive.
To minimise the risks associated with CO it is most important that the furnace is
installed and operated in accordance with this instruction manual. If the furnace
operator experiences any of the effects listed above, the furnace must be isolated from
the gas and electricity supplies immediately and expert advice sought. For safety
guidelines seek the gas manufacturers advice.
