Abstract: The present invention provides decontamination equipment which can be on site with the first responders, and set up on the clean line, ready to process personnel as they move from the contaminated area. In one embodiment the present invention provides a transportable mass personnel decontamination system comprising a transportation means (10) carrying a plurality of individual three compartment processing cubicles (36, 39, 42); (37, 40, 43); (38, 41, 44) for ambulatory personnel, each processing cubicle having enclosure means (49, 50, 51) for each compartment to provide modesty screening of personnel, the first compartment (30, 31) for disrobing, the second compartment (32, 33) containing a temperature and pressure controlled personnel operated shower with a decontaminant dispenser, and the third compartment (34, 35) providing a re-dress area. A soft conveyor liter patient processing line (4, 5, 7) including stations for decontaminating, washing, rinsing, and drying litter patients is included.

Abstract: A window paint scraper for scraping paint from a window while protecting the window frame from the blade. The window paint scraper includes a head portion, a distal end, a proximal end, and a pair of sides. The distal end has a slot therein adapted for removably receiving a blade. A sharp edge of the blade extends away from the distal end. The sharp edge has a width generally equal to a width of the distal end. A handle portion is elongate and is integrally coupled to the proximal end of the head portion. A pair of spacing members places a distance between the sides of the head portion and a window frame. Each of the spacing members is integrally coupled to one of the sides of the head portion. Each of the spacing members is abutted against a junction of the sides and the distal end of the head portion. A bumper protects the widow frame from the sharp edge of the blade. The bumper is integrally coupled to and extends away from the distal end of the head portion.
