Breathing sets are usually mounted behind the seats in the back of the pumping engine's crew cab, where they can be donned en route to a fire scene. A breathing set provides clean air for up to 50 minutes in the thickest toxic smoke, although this time will be significantly reduced if the firefighter is working hard and therefore consuming more air. At major fires, where large numbers of breathing sets will be in use, a mobile breathing set recharge

set up to replace empty air cylinders. A safety control board is deployed whenever breathing sets are used at an incident. This monitors each firefighting team inside a smoke-filled building, how much air they have in their cylinders and the recorded time at which they should emerge.

Thermal imaging cameras allow fire crews to see through the thickest smoke to quickly locate casualties or the seat of a fire, and are now essential items of equipment.

Rescue equipment for dealing with non-fire emergencies such as road crashes and industrial machinery accidents increasingly forms an important part of a fire engine's inventory. High-powered hydraulic cutting and spreading tools enable firemen to take the roof off a car in seconds, while sophisticated lifting and jacking equipment, including inflatable air bags, provides a range of tools to effect rescues from the most difficult and challenging situations. When an accident or crash is very serious, perhaps involving a train or a number of road vehicles, or in the event of a gas explosion that has demolished part of a building, an emergency or heavy rescue tender will attend to provide the additional cutting and lifting gear required. These dedicated fire vehicles are self-contained travelling workshops, often crewed by firefighters experienced in rescue work at major accidents.

Protective all-enclosing suits, usually two types, are carried to allow fire crews to safely work in an area deemed to be hazardous, such as at a fire or incident that involves a chemical substance, either at a plant or in transit. Chemical spill suits are worn over a regular firefighting uniform, together with gloves and a breathing set, to provide protection from the majority of chemical substances. Gas-tight suits provide a higher level of protection when dealing with certain highly hazardous materials that pose a serious threat if even a small amount comes into contact with skin or is ingested. A suit completely encloses a firefighter and his breathing set. Hazardous-material emergencies may also call for the use of a radiological measuring device.
