resorting to extinguishing agents.
Medium Fire Situation. Indicates a fire which may be extinguished with the operation
of two handlines.

area by members of the Inside Team. One of these members may
make their way to a front window to inform the chauffeur that they
are “in”, relieving him/her of the necessity of performing VEIS
from the aerial.
When the chauffer is not contacted by a member of the Inside
Team, the chauffeur must assume that they have been unable to get
past the fire, or are otherwise heavily engaged. In such instances
and where fire conditions permit, the chauffeur should attempt
entry and search.

should be relayed to the dispatcher for transmittal over the department
radio. A Battalion Chief, preferably a Foam Coordinator, should be
assigned this duty.
