ABSTRACT
Many unusual factors will face the response team member and the hazardous waste site worker. These may range from naturally occurring situations such as cold, heat, and wind to manmade objects such as personal protective clothing and equipment, power lines, gas lines, or other barriers that personnel have to use or work around. Oxygen deficiency can occur at almost any hazardous materials incident, especially if there is a chemical present that displaces air or is heavier than air. The problem of oxygen deficiency can also occur in low-lying areas such as gullies, culverts, drain pipes, etc., where chemicals have had a chance to settle. Symptoms of an oxygen-deficient atmosphere include impaired vision, reduced attention span, irrational judgment, coordination changes, and increased heart and breathing rates. In any response or hazardous waste site operation, safety must be a very important factor so that everyone may come out of the operation safely and healthfully.
