HEATH AND GRASS FIRES
There are three types of heath and
grass fire:
•
Heath and Grass fires in

1) HEATH AND GRASS FIRES
IN NON-PEATY SOIL
Characteristics
• The fire only travels through surface
growth
Risks:
• Personnel becoming isolated
• Lack of water supplies
Extinguishing Methods:
• To extinguish use beaters or water
• Consider the ‘Flexible Backpack
Extinguisher’
• Consider use of HVP & Water carrier

2) HEATH AND GRASS FIRES
IN PEATY SOIL
Characteristics
•
Fires travel underground as well as
above ground
• Fire travelling underground is almost
invisible
Risks:
•
•
Injury to personnel due to soft ground
Limited access for vehicles & by foot – fatigue, stress
Extinguishing Methods:
•
•
•
Surface fires are extinguished as per non-peaty soil mentioned
previously
Consider use of HVP & Water carrier
Underground fires can be extinguished either by:
i) Trenching ii) Water Jets

3) GORSE, BRACKEN AND
UNDERGROWTH FIRES
Characteristics
• Generally more dense
and wider covering
Risks:
• Personnel & public near by
• Carrying equipment over rough terrain
Extinguishing Methods:
• Fire Breaks
• High pressure hose reel jets
• Wetting a fire break
• Consider use of HVP & Water carrier
• Beaters – limited use

WOODLAND FIRES
Characteristics:
•
•
•
•
•
Numerous sizes and types of trees
Sparks can travel long distances causing
secondary fires
Change of wind directions
Underground fires
Crown Fires
Extinguish by:
•
•
•
•
Create fire breaks
Beating – limited use
Use of water – jets and hosereels
Consider use of HVP & Water carrier
Crown Fires: This is a term used when the fire spreads from one
tree to the next, high up in the tree canopy. It causes problems with
the fire spreading over the top of firefighters and it’s extremely difficult
to extinguish.

FIRE SPREAD & ACCESS
Speed of fire spread due to:
Environmental conditions –
• Weather, temperature, wind direction (speed
and strength)
• Type (FUEL) & size of vegetation area
Access for appliances & personnel:
• Limited with large open areas of
vegetation
• Terrains vary - steep hillsides to soft
boggy areas
