A chemical protective poncho system for encapsulating a patient is presented. The system has a body extending a length between a top end and a bottom end and having a hood attached near the top end and having a liner attached near the bottom end. The system includes a layer of adsorbent impregnated media capable of filtering chemical agents while allowing oxygen and carbon dioxide to pass through the material. The chemical protective poncho is specially adapted to fit over the top of a patient and chemically seal the lower portion of the patient while allowing the patient ambulatory freedom. The system also includes ports for intravenous access as well as a port for respiratory access. The system may also include a powered air purifying respirator which positively pressurizes the interior space of the system.

Embodiments of particle protection headwear apparatuses and use thereof are detailed herein. In general, embodiments of the present invention include a shield and a shroud which couple to, or are partially or wholly integral with, a hat. The shield extends downwardly from the hat and is typically embodied as part of the hat. Further, the shield is designed for a user to be able to look through it. The shroud is coupled to and extends downwardly from the shield and the hat. The shroud extends entirely around a perimeter of the hat to form a breathable barrier between particles and the user's head. The shroud may be removeable from the shield and washable.

A personal protection and ventilation system is provided. The system includes a gown having front and rear panels, a hood, and visor; a fan; an air tube; and a helmet. The fan is positioned between the wearer and a body-facing surface of the rear panel. The front panel and at least a portion of the hood are formed from a first material including a first spunbond layer, a spunbond-meltblown-spunbond laminate, and a liquid impervious elastic film disposed therebetween. The first material has an air volumetric flow rate of less than about 1 standard cubic feet per minute (scfm). The rear panel is formed from a second material including a nonwoven laminate having an air volumetric flow rate of about 20 scfm to about 80 scfm. Therefore, the fan is able to intake a sufficient amount of air from the environment through the rear panel to provide cooling/ventilation to the hood.

Proposed is an emergency evacuation oxygen mask provided with a hood configured to be worn on a user's head and an oxygen canister configured to supply oxygen to the user who wears the hood. The emergency evacuation oxygen mask includes an upper cover in which the hood is accommodated, a female coupling portion coupled to a lower end portion of the upper cover and connected to an oxygen supply port that is provided at the hood, and a male coupling portion provided on the oxygen canister and coupled to the female coupling portion, wherein when the upper cover or the oxygen canister is rotated, oxygen is discharged from the oxygen canister.

A headgear device for a user including an integrated face shield, mask and hood. More specifically, the headgear device includes a hood, a face shield, and a moisture barrier fabric to cover the user's mouth when the headgear device is worn and direct air out through a breathable particle filtration fabric.

A dust hood is provided having a front face of an inelastic material and a rear face of the inelastic material. The front face has a first opening configured to correspond to a location of a user's eye protection when worn by the user. The front face also has a primary breathing opening configured to correspond to a respirator hose or respirator air intake location when worn by a user. The dust hood openings each comprise a gasket for sealing the corresponding openings against corresponding accessories. Accordingly, the first opening gasket seals the hood against a user's eye protection and the second opening gasket seals the primary breathing opening against a user's respirator hose or respirator air intake.
