My day job is as a civil service electrician for the last thirty-four years at the Veteran s Administration hospital. March 5, 2006,1 had thirty-four years with civil service. After duty at the VA hospital, all the rest is a volunteer as a firefighter, rescue worker, or helping the county sheriff and the State Highway Patrol as an interpreter. Basically, I stay pretty busy. The federal government gave us three fire vehicles after the chlorine gas incident because our old equipment was done-in by corrosion caused directly by poison chlorine gas. This gas took the paint and chrome off our fire vehicles so it was unusable for any other purpose what do you think it did to my lungs and body at the same time ...

Incidents in the technical equipment, crashes in the poisonous gas supply pipes or crashes and explosions of gas storage tanks. 

Gas incidents A new requirement which places on the supplier of gas, whether through a fixed pipe or by refillable containers, a duty to report immediately to the enforcing authority any incident resulting from the use of their product that causes death or any of the injuries listed above. Particularly referred to is poisoning due to incomplete combustion of gas and inadequate ventilation. 

For transportation accidents by railroad, see also [47]. This report gives a survey of damage during 177 anhydrous ammonia highway incidents and 570 rail incidents in the U.S. for the years 1971 to 1982. It lists the identification number for anhydrous ammonia as UN1005 and the required labeling as a poisonous gas. 

Only two poisons in this group require routine exclusion. These are cyanide and carbon monoxide. The main exceptions to diis general recommendation are cases arising from an incident on industrial premises, or the use and abuse of compressed solvent fuels and aerosols. In the former case, a list of the industrial gases used or available on site should be requested in die latter case, most of the relevant compounds are covered by head-space gas chromatography as mentioned above. 

Carbon monoxide (CO), one of three oxides of carbon, is an odorless, colorless, toxic gas at 25°C and 1 atm. It is a by-product of the combustion of carbon-containing compounds when there is a limited oxygen supply. Incidents of carbon monoxide poisoning are especially common in the winter in cold areas of the world when blocked furnace vents limit the availability of oxygen. The bonding in carbon monoxide, which has the Lewis structure C=0 , is described in terms of sp hybridized carbon and oxygen atoms that interact to form one a and two v bonds. 

Lead and sulphur are derived from the fuel and there is a complex equilibrium dependent upon temperatures and gas composition controlling the absorption/desorption of these poisons. In the case of lead, extended trials have demonstrated the feasibility (ref. 20) of successful operation of oxidation catalysts on leaded fuel. However, it has been noted that in the decade since introduction of lead-free fuel in the USA, residual lead levels have fallen dramatically. In that market, where leaded and unleaded fuels are both available, incidents of poisoning reflect contamination of distribution equipment or deliberate misfuelling (refs. 21,22). Sulphur may also be derived from lube oil but its impact in the sense of poisoning is low on PGM catalysts. Interaction with catalyst components can, however, influence secondary/unregulated emissions of... 

Corrosives in contact with a poison may produce poison gases as the poison decomposes. In responding to an incident involving corrosives, the toxicity of the vapors could be much more of a concern for personnel than the corrosivity. When acids come in contact with cyanide, hydrogen cyanide gas, which is highly toxic, with a TLV of 10 ppm in air, is produced. The structure and molecular formula of phosphorous trichloride are shown in Figure 10.8.
