Some chemicals are more toxic via inhalation relative to other routes of exposure. An approved program for use of respirators or other protective action may be required. 11.4.6 Contaminated soil Informative advisory —See requirements in Section 13.1.3 . Regardless of known site contaminants in soil, groundwater or condensate, special procedures are often required when handling derived waste from any contaminated site. Considerations can include, among other responsible practices, establishing off-site eating areas and cordoning off restricted areas. 11.4.7 Explosive or fire hazards Note— For worker health guidance, see: The NIOSH pocket guide to chemical hazards : www.cdc.gov/niosh/npg/ Partial List of Chemicals Commonly Associated with Explosive or Fire Hazards (and potential sources) Advisory —Lists provided herein are intended to shed light on some of the more common contaminants found at contaminated residential sites. There are many thousands of contaminants in commerce and others that occur naturally. Compiling a definitive list of contaminants that might be encountered is not feasible. Health Advisory —Responsible care with explosive gases should include monitoring equipment for detection of hazards, safe tools and an emergency response plan, policy and process in the event of accident. Gasoline (contains benzene, toluene, ethylbenzene, xylenes [BTEX], other substituted aromatics, alkanes, alkenes, etc.) Kerosene/Jet Fuel (less of a hazard than gasoline because the volatile content is lower) Diesel Fuel/#2 Fuel Oil (less of a hazard than gasoline because the volatile content is lower) Acrolein (2-propenal) Methane (natural gas - odorless, naturally occurring product of biodegradation; petroleum degradation) 1,3-butadiene para-Cresol (4-hydroxytoluene or 4-methylphenol) Carbon disulfide Acetone ortho-Cresol (2-hydroxytoluene or 2-methylphenol) Formaldehyde Diethyl ether Acrylonitrile Methyl isobutyl ketone
