Abstract: An improved personal protective device and composition thereof. The device comprises arc flash spectacles or goggles, an arc flash faceshield or an arc flash hood window to provide optical clarity, specifically color acuity. The spectacles or goggles, the faceshield and the hood window include polycarbonate material for high-impact, high-mass performance, and surface charring during arc flash exposure and provides an arc flash protective rating of at least 4 cal/cm2 (in the case of eyewear and face shields) or at least 15 cal/cm2 (in the case of hood windows).

Abstract: An arc flash resistant material includes a para-aramid non-woven material substrate and a polyurethane film containing approximately 10-40% by weight of antimony oxide (Sb2O3, Sb2O5) and decabromodiphenyl oxide containing a high level of aromatic bromine laminated to a first surface and a second surface of the para-aramid non-woven material substrate. The arc flash resistant material may be breathable and include antistatic properties. The arc flash resistant material is light weight, exhibits an exceptionally high level of protection from an arc flash hazard, and possesses a low particulate level that is required for clean room applications.

Abstract: An electrical arc flash protection blanket for protecting workers from electrical arc flashes. The blanket is composed of two or more layers where the layer closest to the electrical arc source is of a fiberglass material and the remainder of the layers are of fiberglass and/or a flame-retardant (FR) materials. The layers overlap so that the they can be attached around the entire perimeter. Preferred fiberglass fabrics are woven with a warp yarn break strength between about 0.7 and 1.5 times the fill yarn break strength. FR materials include FR cotton, para-aramids, and meta-aramids. A fastening structure is used to install the blanket for use. Contemplated fastening structures include straps with temporary fasteners around the blanket perimeter and eyelets. Optional integral handles facilitate carrying and installation.

Abstract: An automobile in which an external appearance of a body of the automobile is formed to assume substantially identically shaped front and rear portions, and in which visors are provided at a front head portion and a rear head portion of a roof of the body. There is obtained an automobile of high utility value capable of decreasing manufacturing costs through rationalization of manufacturing operations, and of securing safety during driving and comfort within the automobile.

Abstract: An automobile capable of protecting a driver from direct rays of the sun from the front or rear side of body, and further enhancing the power of attention to the front side thereof. The automobile has a front visor protruded forward from a front head portion of a body and a rear visor protruded backward from a rear head portion of the body.
