Many fire-ground tasks can be accomplished by one firefighter during an emergency and in non-emergency situations. One single-firefighter task that is beneficial for small teams to understand is bundling of the standpipe or highrise kit.
We have come to the fifth part of our series on standpipes. So far, we have looked at using standpipes within buildings, either wet or dry standpipes. But what happens when the provided standpipe will not or does not work when we need it?
We have been exploring the topic of standpipe-equipped buildings and highrise operations. In November, we looked at the equipment needed to conduct standpipe operations, and I mentioned that firefighters can carry only so much, which leads to the next topic: how many firefighters are needed for this type of operation?
In my August and September columns we looked at options for securing the standpipe – on the fire floor or the floor below the fire.
There are debates among fire service personnel about where firefighters should secure the standpipe in high-rise buildings. Some firefighters propose that the standpipe be secured on the fire floor while others advocate that crews hit the standpipe on the floor below the fire floor. There are considerations for both options that fire services need to understand before choosing one or the other.
Most mid-rise or high-rise buildings are equipped with standpipe systems that allow firefighters to access water. Fire crews need to consider many elements with respect to securing a standpipe system, such as the size of hoselines, types of nozzles, tools or equipment to bring, the number of firefighters needed, where to stage all of the equipment, and whether or not to use the elevator.
In this series about rapid fire development (RFD), we have focused on the science behind flashover and how water is used to aggressively cool the gases and the environment in order to reduce the heat-release rate and contain radiant heat. The third and final part of this series is a study of ventilation as a companion to using water for aggressive cooling.
Firefighters should be aware of situations that lead to rapid fire development (RFD) – occurrences such as flashovers, backdrafts and smoke explosions – and how to take aggressive action to protect themselves. In the March issue of Fire Fighting in Canada, we examined why better gear and new construction materials expose firefighters to RFD today more than ever before.
Rapid fire development (RFD) is a concern that all firefighters face whether they are undertaking engine-company or truck-company functions. RFD refers to occurrences such as flashover, backdrafts and smoke explosions, and can take place at any structure, at any time of day, anywhere in the country.
The transitional fire attack is a relatively new tactic by name, but some of its practices have been around for many years. This tactic gained traction in the last two years as a result of the studies completed by the National Institute of Standards and Technology (NIST) and Underwriters’ Laboratories (UL) in New York and Chicago.
