A pressure reducer for a self-contained breathing apparatus (SCBA). The reducer may include an integrated pneumatic alerting device with an upstream antechamber, and an integral refill air passage with a first end that is fluidically connected to a refill air inlet of the reducer and with a second, opposing end that is fluidically connected to the upstream antechamber of the integrated pneumatic alerting device.

A self-contained breathing apparatus (SCBA) is presented that comprises a backframe configured to support a high-pressure air cylinder, a sensor module mounted to the backframe, and a console coupled to the SCBA. The console comprises a pneumatic connection coupled to the high pressure air cylinder, an electronics connection coupled to the sensor module, and a display component. The console is configured to operate in a functional mode and in an equipment check mode. In the equipment check mode, the console is configured to provide equipment check instructions to a user of the SCBA. In the equipment check mode, a sensor signal is received from the sensor module using the electronics connection. A pressure of the high-pressure air cylinder is measured using the pneumatics connection.

A modular breathing apparatus system integrating self-contained breathing apparatus (SCBA) and powered air purifying respirator (PAPR) capabilities in a unified platform includes a body-worn carrier frame with a removable air canister carrier configured to accommodate varying configurations of pressurized air canisters. A PAPR system with filter cartridges and blower removably attaches to the air canister carrier via a latching mechanism. A second stage regulator configured for connection to protective equipment selectively receives air from either the PAPR system or the SCBA system through an integrated shutoff mechanism. The modular design enables rapid reconfiguration between different air canister configurations without modifying other system components. The air canister carrier can be swapped to accommodate different sizes and numbers of pressurized air canisters while maintaining compatibility with the integrated PAPR system, addressing inefficiencies in traditional separate SCBA and PAPR systems and providing operational flexibility for varied mission requirements.

A support for a breathing apparatus including a cylinder cradle with a retaining surface for retaining a cylinder of compressed gas and a cylinder glider including a gliding element, the gliding element configured to support the cylinder above the retaining surface, wherein the cylinder glider is longitudinally separated from the retaining surface of the cylinder cradle.

A protective shield is provided for covering a self-contained breathing apparatus (SCBA) mask or a full-face air purifying respirator (APR) lens to prevent damage and scratching. The shield consists of a die cut shape of thermoplastic sheet that duplicates the outline of the self-contained breathing apparatus mask lens and / or frame. The protective shield can be produced using various grades, colors and / or densities of material replicating limited visibility or blackout conditions. To protect the majority of the plastic lens, the shape of the shield includes a peripheral overlap onto the mask utilizing the SCBA lens frame. The shield can be attached to the self-contained breathing apparatus face mask by means of any of the following: bungee, hook, or elastic cord; all of which allows the shield to be attached or removed quickly. Many SCBA / APR training exercises require limited visibility. The invention can be used as an effective training tool to prevent light transmission and simulate extremely limited visibility.

A reducer for a self-contained breathing apparatus (SCBA), comprising a primary air pathway with a primary metering valve and a secondary air pathway with a secondary metering valve. The reducer has an Emergency Breathing Support System (EBSS) outlet that is fluidly connected to a branch line of the secondary air pathway.

A rescue guidance system includes a thermal imager mountable on a self-contained breathing apparatus pack and capturing thermal image data of an area at least partially surrounded by a wearer including and a display unit configured for mounting within a face shield associated with the self-contained breathing apparatus in a field of view of the wearer. The display unit has a plurality of LED light elements configured as directional indicators relative to the wearer. A controller receives the image data and determines a location of a person within the thermal image data and correlates the location of the person within the thermal image data to an approximate location of the person relative to the wearer and illuminates a selected one of the plurality of directional indicators approximately corresponding with a direction of the location of the person relative the wearer.

A portable, modular air delivery system for refilling self-contained breathing apparatus (SCBA) cylinders under adverse field conditions includes a ruggedized enclosure housing a four-stage breathing air compressor with interstage cooling driven by a diesel engine, modular air storage cylinders rated to 6,000 psi, and a distribution manifold with four high-pressure outlets for simultaneous refilling operations. The compressor provides dual-pressure outputs for SCBA refilling and pneumatic tool operation. An extended-length hose system enables cylinder refilling at distances up to 500 feet. The system performs cascade filling operations and features dual rolling door assemblies for bilateral access. Weatherproofed components enable operation during rain while maintaining Grade D breathing air quality. Connector fittings accommodate US military and Israeli SCBA standards. Modular construction permits component removal from a mobile trailer platform for redistribution. The system meets 463L pallet constraints and achieves fill times under 5 minutes.
