Abstract: An emergency response system wristwatch having upper and lower case sections connected by a hinge is combined with a removable interference bracket disposed between the two case sections. The upper case section has opposing rear and front surfaces, where the front surface includes a dial face. The upper case section is operable to pivot on the hinge between open and closed positions. The lower case section has an activation button that is exposed when the upper case section is in the open position. When the upper case section is in the closed position, the rear surface of the upper case section is disposed adjacent the activation button. Without the removable interference bracket between the upper and lower case sections, the rear surface of the upper case section is operable to move toward the lower case section and press upon the activation button if pressure is applied to the dial face.

Abstract: In an asbestos scraping assembly, the arm of an operator is confortably cradled in a scraper extension bracket so as to apply greater force to a scraper blade with less effort by the operator than is required of a hand-held scraper blade. The hand of the operator holds a bar of the scraper extension bracket so as to position the area of contact of the scraper blade cutting edge with the surface from which asbestos is to be removed.

Abstract: An improved glove/mitten has been developed which includes steel needles projecting from one side of the glove/mitten to ensure complete removal of asbestos-containing materials from complex structures. The glove/mitten is bendable to adapt itself to the shape of the structure from which the asbestos-containing material is to be removed.

Abstract: A fire condition detection and control system for use with air moving and filtering units. The system includes one or more remote fire condition detection units, which sense heat or smoke and, upon such sensing, transmit a signal indicative of an alarm condition to one or more air moving and filtering units located within a containment area. The transmission is by wireless radio frequency transmission and/or a wired transmission line or cable. The air moving and filtering units detect the alarm condition and disconnect power to the blower motor of the air moving and filtering unit. The receiver and control circuitry may be integral with the air moving and filtering unit, or may be part of a separate control unit that plugs into conventional air moving and filtering units.

Abstract: A containment bag system specifically used for the removal of asbestos insulation from asbestos covered pipes and valves without contamination of the worker or the surrounding environment. A method of removing asbestos and other hazardous materials from limited areas uses a safe containment system. A method for manufacturing the containment system includes heat sealing a length of lay-flat tubing along a bottom edge and preferably along two side edges.

Abstract: A filtration device for filtering airborne contaminants, such as airborne asbestos fibers, from the air, including a housing having an inlet for receiving contaminated air, an outlet for expelling filtered air outside of the housing, a filter, including a HEPA filter, in sealed communication with the inlet, and a blower within the housing for drawing air through the filter means and for expelling the filtered air through the outlet to the outside of the housing. A control and display system continuously senses differential air pressure within the housing and blower speed, converts the differential air pressure and blower speed to an air flow rate value and displays the air flow rate through a display unit. Manually controllable key pad switches are provided to selectively change the desired air flow rate, to set upper and lower pressure limit values, and to set the operating time for the system operation.
