Provided herein are devices, systems, and methods for capturing toxic pollutants, such as polycyclic aromatic hydrocarbons. Certain embodiments of the present disclosure are related to a pollutant-absorbing material that includes an absorbent compound, such as sodium copper chlorophyllin, capable of binding to and capturing a toxic pollutant, and methods of making and using the material for the capture of toxic pollutants. The pollutant-absorbing material can be incorporated into an article worn by a person, such as a shirt or a facemask.

There is disclosed breathing apparatus equipment which may be in the form of a waist mountable manifold. The breathing apparatus equipment comprises a manifold having a manifold inlet port for a source of breathable gas and at least one manifold outlet port for delivering breathable gas to a user. The equipment further comprises a strap arranged to be worn by the user, and a holder coupled to the strap and having a socket. The socket is configured such that the manifold can be removably located within the socket in multiple orientations.

A safety glove includes a knitted inner shell, a first coating covering an exterior surface of the knitted inner shell, a plurality of guard members disposed on the first coating, a second coating covering the first coating and the plurality of guard members, and a third coating covering only a portion of the second coating. A method of manufacturing a safety glove includes kitting fibers to form an inner shell, dipping the inner shell into a first material to form a first coating; securing a plurality of guard members on the first coating, dipping the result into a second material to form a second coating, inspecting the second coating, and, if the second coating passes inspection, dipping only a portion of the result into a third material to form a third coating.

A ventilated hood having an external air flow hose and comprising a filter incorporated in the ventilated hood, and a seal, wherein when the seal is intact, air does not flow through the filter.

Refrigerating clothes may include a clothes body and a refrigerating mechanism having a working medium capable of changing between gas and liquid. The refrigerating mechanism includes a radiating surface and a refrigerating surface, between which the working medium circulates. The refrigerating surface is abutted against the clothes, and the radiating surface is arranged at one side far away from the refrigerating surface. The radiating surface absorbs thermal radiation from sunlight and provides energy for the working medium, the working medium absorbs heat on the refrigerating surface to realize cooling, and continuously circulates in the refrigerating mechanism without need for frequent replacement.

A head protection system includes a safety helmet and a fire protection cloth. The safety helmet includes a helmet shell (105) and a holding device (108) to guarantee a distance (A) between a helmet shell inner side (106) and the user head (102). An air path (110) is formed by a plurality of openings (120) of a fastening ring (125)and the distance between the inner side of the helmet shell and the head of the user. The fastening ring is arranged at least in an area of the user forehead of the user. The fire protection cloth has a fastening strap (230) with rigid fastening elements (235) configured to mesh with an opening of the fastening ring to detachably fasten the fire protection cloth to the safety helmet. The rigid fastening elements fill the plurality of openings in the fastened state to close the air path.

A protective garment system including a bib configured to fit around at least part of an upper portion of a torso of a wearer. The bib includes an outer material and a particulate-blocking material which is configured to be positioned between the outer material and a wearer when the bib is worn. The bib has a perimeter and is configured to be releasably attached to a pair of trousers about the perimeter.

A self-contained functional and physical architecture is described to utilize a honeycomb configuration Positive Temperature Coefficient semiconductor thermistor heater to provide breathable warm air to an individual under cold weather conditions. The high-temperature of the heater element provides substantial efficiency allowing hours long use on battery power only. The invention utilizes pulsed heater operation in combination with lengthwise air mixing to rapidly and efficiently lower the temperature of the high temperature heated air to a temperature that is breathable. The invention solves issues with visor fogging, adaptability to a wide temperature range, and adaptability to a wide range of individual exertion. This system is applicable to a wide range of cold weather work environments, cold weather sports, scientific exploration, military operations, or medical needs. Several physical embodiments are described utilizing various forms of helmets and masks.

A two-layer flame resistant garment is disclosed having an outer layer and an inner layer, wherein the outer layer has a flame resistant shell fabric laminated to a waterproof breathable layer. Also disclosed is a flame resistant garment having one layer fabric construction, wherein the one layer has a flame resistant outer shell, a waterproof breathable membrane, and a thermal management polymer coating.

Disclosed is a device for protecting a user from smoke or fire, including a sealed dome-like cover. An opening provided in the cover front portion enables emergency oxygen to force smoke present under the cover to be expelled by positive air pressure through a space below the waist. The dome-like cover is overlaid from above the top of the head to at least the waist of the user and connected to a source of oxygen. The device is reversible so that it can also be used as a stretcher. The materials used enable use as a thermal blanket. The device can be provided compactly folded in a bag that can provide lumbar support thereby ensuring that miners will always carry the device with them. A step of vacuum sealing for a predetermined amount of time ensures malleability of the compact device for enhanced lumbar support and device longevity.
