Fire Risk Warning 

In the very rare event that a burning ember or spark is drawn 
into the fume extraction unit, it may be possible that the 
filters will ignite. 
Whilst any resultant fire would typically be retained within 
the fume extraction unit, the damage to the extractor would 
be significant. 
It is therefore essential to minimise this risk by undertaking 
an appropriate assessment to determine:- 
 
a). Whether additional fire protection equipment should be 
installed.  
 
b). Appropriate maintenance procedures to prevent the risk 
of build-up of debris which could potentially combust. 

 

This unit should not be used on processes with sparks of 
flammable materials or with explosive dusts and gases, 
without implementation of additional precautions. 
 
It is essential that nozzles or other extraction/fume 
capture devices and hoses/pipework are cleaned regularly 
to prevent the build-up of potentially ignitable debris.
