Answer to Question 2:

Hi Marcus,

There are 4 main types of general fire extinguishers used in workplaces : water, dry powder, CO2 and foam. I have outlined their uses below. It is of absolute importance that all employees are trained in the use of extinguishers and only use them on small fires so they do not put themselves at risk.


Water
 

Water fire extinguishers are used for cloth, paper and wood fires only.
 

Dry Powder
Dry powder fire extinguishers can be used on most fires including electrical fires.  However, in areas where there might be a wind or draught, the powder fire extinguisher will probably not extinguish a cloth, paper or wood fire.

Furthermore, a risk assessment must be carried out to see if the discharge of a powder extinguisher will impact on the visibility of emergency egress routes.

Also if members of the staff suffer from asthmatic conditions, this would exacerbate this and result in having to deal with a possible medical emergency.
 

Carbon Dioxide
Carbon dioxide fire extinguishers can be used on electrical fires.  It will assist in the extinguishing of flammable liquids.
 
Foam
Foam can be used on Class A fire risks such as paper, wood and cloth, as well as all other types.
