www.bullard.com Dual-Cool™ Climate Control Tube and DC65 Vest User Manual TM Includes: DC60 Series Dual-Cool tube, cooling vest connector hose, reinforcing rings, belt bracket, and belt. Note: The DC65 cooling vest and respirator breathing tube must be ordered separately. Function: The DC60 Dual-Cool tube is NIOSH approved to supply a continuous flow of cool air to Bullard PC90 Series supplied-air containment respirators. All Bullard parts must be present and properly assembled to constitute a NIOSH approved respirator. NOTE The DC60 Dual-Cool tube cannot be used with a low pressure air source such as an ambient air pump. Air Quality Requirements Respirable air must be supplied to the point-of-attachment of the NIOSH approved Bullard air supply hose, where the air supply hose connects to the fitting. Always use an inlet filter on your air source and monitors and alarms as necessary to assure clean, breathable air. Supplied breathing air must at least meet or exceed the requirements for Type 1 gaseous air as described in the Compressed Gas Association Commodity Specification G-7.1 (Grade D or higher quality) and specified by Federal Law 42 CFR, Part 84, Subpart J, 84.141(b) and 29 CFR 1910.134(i)(1)(ii). The requirements for Grade D breathable air include: Oxygen ......................................................................... 19.5-23.5% Hydrocarbons in mg/m3 of gas .............................. 5 mg/m3 max. Carbon monoxide ...................................................... 10 ppm max. Carbon dioxide ..................................................... 1,000 ppm max. Odor ............................................................ No pronounced odor* No toxic contaminants at levels that make air unsafe to breathe. * Specific measurement of odor in gaseous air is impractical. Air normally may have a slight odor. The presence of a pronounced odor should render the air unsatisfactory. Contact the Compressed Gas Association (1235 Jefferson David Highway, Arlington, VA 22202 or www.cganet.com) for complete details on Commodity Specification G-7.1. For use with PC90 Series Containment Airline Respirators WARNING Before using this product, read and follow all directions and warnings, including those in the respirator instruction manual. The respirator’s air source must supply clean, breathable air, Grade D or better, at all times. The respirator does not purify air or filter out contaminants. Connecting the respirator to a line supplying nitrogen or other harmful gases could cause death or serious injury. Failure to follow these instructions could result in death or serious injury.
