Wildland Fire Incident Management Field Guide i PREFACE The Wildland Fire Incident Management Field Guide is a revision of what used to be called the Fireline Handbook, PMS 410-1.This guide has been renamed because, over time, the original purpose of the Fireline Handbook had been replaced by the Incident Response Pocket Guide, PMS 461. When we look back at the history of forest management, we can see that the forests from centuries ago had fewer trees, but they were taller and stronger. Each element described above increases the potential risk of a forest fire growing out of control. [8], Type 5s are normally used as an initial attack engine atop a medium duty chassis. For most people, a forest fire is synonymous with disaster. Engines such as Type 3's can pump from a stationary position using a power take off (PTO). 4. Forest fires promote healthier trees. Wanna talk? They can threaten communities and destroy vast amounts of timber resources, resulting in costly losses. Additionally, there are requirements laid out by the National Fire Protection Association in NFPA 1906: Standard for Wildland Fire Apparatus. Lets start with the obvious. One of the features that makes these engines ideal for vegetation fires is that they can pump water while driving, whereas most, but not all traditional engines must be put into park to flow water, it depends on the specifications to which the Fire Department wants the vehicle to be built. The new fire engine will have many state-of-the-art features that better support firefighters, our community, and the environment.
