A firefighter hood comprising a hood body configured to fit around a head of a wearer, wherein the hood body includes a face opening configured to be aligned with a face of the wearer when the hood is worn. The hood further includes a flap coupled to the hood body. The flap is movable between an extended position wherein the flap covers only part of the opening in front view, and a retracted position wherein the flap does not cover any of the opening in front view or covers less of the opening in front view compared to when the flap is in the extended position.

A respirator has one or more electrodes of e.g. conductive elastomer disposed on the surface of a face sealing member opposite to the surface which seals against the user's face. In use the integrity of the seal formed between the sealing member and the user's face is monitored by monitoring the electrical capacitance across that member between the electrode(s) and the user's face.

A filtration device including a fluid-impermeable housing having a gas inlet and outlet, and containing within the housing first filter media particles of an extended surface area substrate and containing at least one metal impregnant, and second filter media particles of an extended surface area zirconium hydroxide substrate and containing zinc (hydr)oxide. The first or second filter media particles also contain an amine-functional material. The device may be used in atmospheres containing various harmful gases, and may provide particularly useful improvements in breakthrough times for nitrogen dioxide, hydrogen sulfide, ammonia and formaldehyde compared to a device containing only the first filter media particles or only the second filter media particles.

A fastening unit, in particular a fastening unit for modules which are intended to supply a user of a breathing mask or breathing hood with breathable air, and to such modules. The fastening unit is designed to secure one module relative to another module, and has a first component part for assembly with the other module and a second component part for assembly with the module. The second component part is rotatable, by means of the first component part, about a predetermined angle relative to the first component part; and first and second subcomponents within the region of the defined angle can engage with each other in a plurality of positions.

A protective hood system for a user is disclosed. The hood system includes a hood defining a substantially cylindrical shape and is designed to surround a head of the user. The hood system further includes a neck portion disposed at a bottom end of the hood and is designed to contact a neck of the user. An air filter and air source inlet are coupled to the hood. The air source inlet is designed to connect to an air source which supplies air to the hood.
