The present description provides components that allow a respiratory protection device to be secured in a position of use by attachment with a headwear suspension. In some exemplary embodiments, a harness adapter is positioned along a strap of a headwear suspension and includes a harness attachment element that may releasably attach to a strap component of a respiratory harness assembly.

A system for and method of providing safety equipment to a user is provided. The system includes a headgear platform that is configured to be secured to a head of a while supporting a plurality of safety accessories. Each safety accessory is configured to move independent of each of the other safety accessories so as to allow for quick and easy access and deployment of only the safety equipment that is required or otherwise desired for a particular job. When a particular safety accessory is no longer required or desired, it can be quickly and easily moved to a stowed configuration, thereby moving the safety accessory out of the user's way while maintaining it in close proximity for quick and easy redeployment when required or desired.

A personal air filtration system comprising a rigid component, a flexible component, wherein the rigid component and the flexible component combine to cover at least a user's mouth and nostrils and form a seal therearound, an intake port with an inlet filter, an exhaust port, an air mover causing filtered air to enter the intake port and exhaust air to exit the exhaust port, and an app running on a user's smart device, wherein a smart app is configured to control and monitor operation of the system.

Example hard hat adapters include: a coupling mechanism to removably couple the hard hat adapter to a hard hat; an upper arm configured to removably couple to an outer face shield and an inner face shield; and a lower arm configured to removably couple to a blower shell, wherein the outer face shield and the inner face shield are configured to removably couple to the hard hat adapter at a first pivot point of the hard hat adapter.

A helmet includes a helmet body and a gas detection and purification device. The gas detection and purification device in includes a body, a purification module, a gas-guiding unit, a gas detection module, and a power module. The gas detection module calculates the gas detection data obtained by the gas detection module so as to control the gas-guiding unit to start or stop operation based on the gas detection data. When the gas-guiding unit is in operation, the gas-guiding unit guides the gas into the body and to pass through the purification module for being filtered and purified to become a purified gas, and the gas-guiding unit discharges the purified gas out of the body to the nose portion, or the mouth portion, or both the nose portion and the mouth portion of the wearer for providing the wearer with the purified gas to breath.

Antivirus helmets and techniques to manufacture the antivirus helmets are provided. The antivirus helmets can protect subjects from viruses, bacteria, or other types of pathogens. The antivirus helmets can be modular and can isolate a subject wearing the antivirus helmets from the surrounding environment. The antivirus helmets can be deformable and can be worn during extended periods while protecting a subject wearing the antivirus helmet and other subjects in the environment surrounding the subject.

A powered air respirator kit comprising visor (9) removably attachable to a front edge of a safety helmet (4), a drive unit (1) removably attachable to said safety helmet (4), at least one filter module removably attachable to said safety helmet such that, in use, a fluid flow path is defined through said filter module to a space defined between a user's face and an inner surface of said visor, the kit further comprising a power module (10) removably attachable to said safety helmet and, in use, electrically connectable to said drive unit (1).

The present disclosure relates to a buckle for connecting a strap and a respirator harness including the same. In particular, according to one aspect of the present disclosure, a buckle for connecting a strap including a coupler configured to extend from one position, a strap connector at which a strap connecting hole is formed, wherein the strap connecting hole is connected to a strap which is connected to a mask body, and a hooking portion connected to the one position and including a surface configured to face the coupler, wherein a tap of a helmet or a tap of a head cradle is accommodated between the coupler and the hooking portion so that a position thereof is fixed, and a respirator harness including the same are provided.

An integrated helmet and respirator system comprises a shell defining a helmet portion, the helmet portion being bounded by a peripheral edge. An annular shroud has an upper edge and a lower edge, the upper edge removably attached to the peripheral edge of the helmet portion and the lower edge attached to an annular frame member. A front portion of the annular shroud defines a visor. A one-way exhaust valve is received within an opening in the annular frame member. The one-way exhaust valve is configured to allow an exhalation gas exhaled by a user to exit an interior of the integrated helmet and respirator system and to prevent or minimize ambient air from entering the interior of the integrated helmet and respirator system. A neck dam extends downward from the frame and is configured to prevent or minimize ambient air from entering the interior of the integrated helmet and respirator system.

A method of manufacturing an article of personal protective equipment, such as a protective glove, headgear, footwear, suit, or other protective device, wearable by a wearer for protecting the wearer against noxious agents, such as an article of chemical, biological, radiological and nuclear (CBRN) personal protective equipment. The article of personal protective equipment may comprise a plurality of regions that cover different parts of the wearer's body and have different properties, such as different levels of protection against noxious agents, breath ability, heat loss capability, dexterity, tactility, stretchability, and/or another function.
