Oxidizers will nearly always be identified as such on their MSDSs or International Chemical Safety Cards. They may be identified as DOT/UN Hazard Class 5.1 materials for shipping purposes and labeled as oxidizers. However, some oxidizers are classified otherwise. Chlorine, for example, is DOT/UN Class 2.3 (gases toxic by inhalation) and labeled as POISON GAS for shipping purposes it may also be labeled as a corrosive material. Liquid oxygen is Class 2.2 (nonflammable nontoxic compressed gases) but should be labeled as NONFLAMMABLE GAS and OXIDIZER.

Systemic absorption of agents that inhibit the cholinesterase enzymes can result in miosis. Such substances are present in most insecticides and many toxic nerve gases. Toxic episodes involving the pupil have occurred in workers in fields being dusted with insecticides from an airplane. The miotic pupils of affected patients may not return to normal imtil 30 to 45 days after exposure to the toxic agent. 

Toiidty.—In general, it may be said that, for the lethal and casualty-producing gases, toxicity is probably the most important roquisito, Since the ca.suatty effects of. most gases are in direct proportion to their toxiciiies, it follow s that the more toxic the gas, the more effective ainJ...

Confirmation that safety equipment for personal use, eyewash fountains, first-aid boxes, breathing apparatus, gas detectors for dangerous gases (toxic, inflammable), and gas masks are in working order. 

Chemical Properties. Plasticizer increases free volume and molecular mobility, which increases permeability of small molecules of liquids and gases. Toxicity of some plasticizers to small laboratory animals has led to considerable environmental and political concern, but they have never caused any trouble to human beings on the contrary, the inventor of plasticized PVC lived healthily to the age of 101. 

Toxic Gases. Toxic gases endanger life when inhaled. Gases such as chlorine, hydrogen sulfide, sulfur dioxide, ammonia, and carbon monoxide are poisonous or irritating when inhaled. 

Compressed gas containers must never be dropped, slid, rolled, or allowed to come in contact with sharp objects. They must not be exposed to fire or flames from welding torches. Flammable gases must be stored in properly labeled secured areas away from possible ignition sources, and kept separate from oxidizing gases. Toxic or poisonous gases must be stored in a properly labeled secured area and protected from unauthorized... 

Toxics. When stored in areas with ordinary gases, toxics will hamper manual fire fighting response. The toxic gases are not normally considered a fire problem but by preventing manual response, they are. They should not be stored where ordinary combustibles are stored. All toxic gases should be dispensed from vented sprinklered gas cabinets.
