What is the fire danger rating scale?
The Fire Danger Rating is a measure of the difficulty in controlling or suppressing fires. The Bureau and emergency services use six Fire Danger Ratings to communicate the level of bushfire risk. At higher ratings, any fire that starts will likely to be fast-moving and difficult to control.
How is fire danger rating calculated?
Fire danger The FDI is a calculated using the degree of fuel curing, the air temperature, relative humidity, and wind speed for a given day. Fire Danger Index (FDI) is estimated using the McArthur Fire Danger Meter for grasslands or forest. The higher the FDI, the higher the fire danger.
What is the rating system for bushfires?
Bush Fire Danger Ratings are based on predicted conditions such as temperature, humidity, wind and the dryness of the landscape. The higher the fire danger rating, the more dangerous the conditions. Homes are not designed to withstand fires in catastrophic conditions so you should leave early.

What is a bal fire rating?
A Bushfire Attack Level (BAL) is a means of measuring the severity of a building’s potential exposure to ember attack, radiant heat and direct flame contact. It’s measured in increments of radiant heat (expressed in kilowatts/m2).
What are the fire categories?
Classes of fire
- Class A – fires involving solid materials such as wood, paper or textiles.
- Class B – fires involving flammable liquids such as petrol, diesel or oils.
- Class C – fires involving gases.
- Class D – fires involving metals.
- Class E – fires involving live electrical apparatus. (
What is the highest fire rating?
For example: Class 350 1-Hr. 350°F is the highest the internal temperature of the safe will become when exposed to a fire for 1 hr. UL rated fire safes work when the safe’s exposure to heat is for less time than the stated time. So forget about fireproof and think fire protected for a specified period of time.
