A firefighting or rescue apparatus includes a cab and a body having a storage unit configured to store a self-contained breathing apparatus, contaminated by harmful chemicals at an emergency scene, in the body rather than in the cab where occupants ride, so the occupants are not exposed to the harmful chemicals, which might be hazardous, toxic, carcinogenic or otherwise deleterious to health. The storage unit can include a storage wall mounted on upper and lower telescoping rail systems, and can be selectively movable relative to a compartment opening from a storage mode, where the storage wall is disposed in a compartment to a retrieval mode, where the storage wall extends beyond the opening so a user can access air tank supports to store a self-contained breathing apparatus. Related methods of storing a contaminated apparatus in the storage unit, distal from the cab and occupants thereof, are also provided.

A compact aromatic diffuser configured to be used in conjunction with a breathing mask, allowing full consumption of the diffused essential oil by the user. The compact aromatic diffuser may also be used as a hand held inhaler for application proximate the user's face or a standalone diffuser for treating the atmosphere in a room or closed compartment.

A remotely controlled air supply assembly for simulating emergency situations includes a self-contained breathing apparatus, such as used by firemen and scuba divers. At least one governor is configured to fluidically couple to and position in-line with tubing of the self-contained breathing apparatus. The at least one governor is configured to modify airflow through the tubing. The at least one governor is configured to communicate wirelessly. A controller is wirelessly coupled to the at least one governor. The controller is positioned to communicate at least one command to the at least one governor to compel the at least one governor to modify the airflow through the tubing to simulate an emergency situation.

A breathing gas delivery system comprising a gas flow controller, at least one breathing apparatus, and at least one first length of tubing coupling the breathing apparatus to the gas flow controller. The gas flow controller has a body having an on/off switch, at least one gas input, at least one gas output, and at least one control mechanism for controlling flow of gas to the gas output. The breathing apparatus comprises a T-shaped gas input, a breathing bag coupled to the T-shaped gas input, a second length of tubing having two opposed ends, wherein one end is coupled to the other arm of the T-shaped gas input, a filter coupled the second length of tubing, and a nasal assembly coupled to the filter, the nasal assembly comprising a nasal hood, one or more straps, and an airtight elbow coupling for coupling the nasal hood to the filter.

A personal protection system including a helmet worn on the head of a user and a hood removably coupled to the helmet. The helmet may comprise a ventilation assembly, a chin bar and a control circuit. The chin bar may comprise a mounting device and a hall effect sensor mounted adjacent the mounting device. The hall effect sensor may be in communication with the control circuit. The hood may comprise a transparent face shield and a mounting element configured to removably couple with the mounting device of the helmet. The control circuit may be configured to receive a signal from said hall effect sensor indicating the coupling of said mounting element of said hood with said mounting device of said helmet.

The storage unit can include a storage wall mounted on upper and lower telescoping rail systems, and can be selectively movable relative to a compartment opening from a storage mode, where the storage wall is disposed in a compartment to a retrieval mode, where the storage wall extends beyond the opening so a user can access air tank supports to store a self-contained breathing apparatus. Related methods of storing a contaminated apparatus in the storage unit, distal from the cab and occupants thereof, are also provided.
