Operations Manual
G. Radiant Heat Exposures
H. Streams
1. Must be protected as soon as possible.
2. Radiant exposures must be considered in all directions from the fire buildings since wind
is not an affecting factor.
3. Radiant exposures must be protected by the application of water on the exposure.
4. Water curtains will not adequately protect radiant exposures.
5. Radiant exposure buildings will have to be checked inside, and a hand line will have to
be stretched to protect the inside if necessary.
6. The leeward side of the fire buildings must be covered first, followed by the other sides.
1. Usually a 1¾-inch hand line with fog nozzle can be effective in protecting an exposure.
2. Where there are tall buildings, extreme temperatures, high winds, etc. a 2½-inch line with
solid stream nozzle may be required.
3. Lines must be placed where they will cover the maximum amount of exposed area.
4. If one line will not protect the exposure, additional lines or a large line shall be
positioned.
I. Interior Exposures
1. Interior exposures must be covered similar to exterior exposures in order to keep the fire
from spreading to uninvolved areas and to control fire spread vertically and horizontally
through concealed spaces.
2. Fire in any concealed space must be opened up by the Truck Company and extinguished
by the Engine Company.
3. If Truck personnel are not available Engine personnel will have to perform the work.
4. A 1¾-inch line with fog nozzle is usually adequate to control interior exposures.
5. Additional or larger lines may be required if the first line cannot control the fire.
6. Control of water is a must. Flow what it takes, but preserve property.
