- Hazard
Hazard is a source of potential harm or a situation with a potential to cause loss, Hazards are classified as follows:
(a) Light hazard where the amount and type of combustibles present are such that fire of only small initial size may be expected. Typical light hazards include the following:
(i) Premises such as domestic/residential, offices schoolroom, relocatable buildings, churches and assembly halls which constitute a Class A fire risk.
(ii) Areas where flammable liquids are stored in containers not exceeding 5L capacity, and the total quantity stored in any one of fire compartment does not exceed 25L, which constitute a Class B fire risk.
(b) Ordinary hazard where the amount and type combustibles present are such that fire of only moderate initial size may be expected. Typical ordinary hazard include the following:
(i) Mercantile storage and display areas, showrooms and workshops which constitute a Class A fire risk.
(ii) Areas where flammable liquids are stored in open-top containers in which the exposed surface are of the liquid does not exceed 2m2 , or in container storage, not exceeding a total of 250L in containers each not greater that 20L, which constistute a Class B fire risk.
(c) High hazard where the amount and type of combustibles present are such that fires of large initial size may be expected. Typical high hazard include the following:
(i) Woodworking areas, warehouse with high-piled storage excess of 4.5 m. foam plastics processing and storage which constitute a Class A fire risk.
(ii) Flammable liquids stored in open-top containers where the exposed surface area of the liquid exceeds 2m2 or in container storage exceeding a total of 250L which constitute a Class B fire risk.
NOTES:
1. For further information on the description of hazard classification, the definition used in AS 2118 may be used for guidance.
2. Special consideration should be given to occupancies which, because of their high-fuel load, may more correctly be allocated a high hazard classification.
