For example, people with respiratory problems should avoid the inhalation of solvent vapors from paint since these vapors may bring on breathing difficulties. Thoughtful policies are needed at each phase to protect local residents from unnecessary health risks. NFPA 704 is a labeling system used to identify hazardous materials. An air-supplied respirator or a self-contained breathing apparatus with full facepiece is recommended when vapors/fumes are above exposure limits, up to 20 ppm. /Type /Pages 100% 02 and repeat hr intervals. Later that night, a fire broke out in a dumpster in the lumberyard, igniting the explosives. Clandestine biological warfare laboratories are usually located in what type of areas: What are indicators that a biological incident may have occurred? This includes wastes regulated under the Resource Conservation and Recovery Act (RCRA) and those included on special EPA lists. Many chemicals can be obtained from commercial suppliers or stolen from soft targets such as storage areas and transfer points.
