10 kilowatts/m2 a firefighter in full PPE can withstand that for a very short period of time. So at 29 kilowatts/m2 and above, we've unpiloted ignition of timber. So it means, simply through radiant warmth alone, you’ll get something that will combust. Buildings that are rated as BAL 29 are at severe danger of catching on hearth as a result of burning particles and increased warmth flux. There is also a risk of the constructing changing into exposed to flames. Ember and radiant warmth safety are required within the building of buildings which are rated BAL 29.
