Poisonous Materials

Low-temperatiire liquefied gases are shipped in special ships with insulation between the niiU ana an inner tank. Poisonous materials are shipped in separate tanks built into the ship. This prevents tank leakage from contaminating harbors. Separate tanks are also used to transport pressurized gases. 

If the previous eontents were poisonous, we should assume there is some poisonous material out of sight, and air masks should be worn for entry. 

The New York State Department of Agriculture and Markets relies on the standard adulteration section of its law, but additionally advises that the department is very fussy regarding the use of poisonous material in food-handling establishments, particularly where poisons might come in contact with the food. In New York City the standard adulteration section also applies and additional requirements are aimed at offering protection to the operator during the spraying project. 

With the development of chemical industry the moment has come to equip the laboratories of the sanitary and epidemiological services with modem instrumentarium and methods, capable quickly to establish small (insignificant) quantities of the different groups of poisoning material in the air, the water and the food products. 

Uncertified coal-tar dyes are likely to contain arsenic and other poisonous material, which, when used in food, may render such food injurious to health and, therefore, adulterated under the law.

Several major types of animals that produce poisonous substances have been considered so far in this chapter. With the exception of birds, all classes of the animal kingdom contain members that produce toxic substances. It has now been demonstrated that there are even birds that are toxic. It is believed that such birds do not produce toxins but accumulate toxic alkaloids, including andromedotoxin, batrachotoxins, and cantheridin, from their diets and deposit these poisonous materials in their skin and feathers.19 Toxic animals not covered so far in this chapter are summarized here. 

There are various reasons to agree with the conclusion drawn by Kwan (315) that the surface of a number of metallic catalysts is of a homogeneous nature for chemisorption as long as these catalysts are prepared by a very careful reduction and are kept free from any poisoning materials. We shall see that it is very difficult to fulfill these conditions. 

Unpolluted water is safe. Observation almost all the water in nature is safe for drinking, and the rare cases that are not safe are nontasty, e.g., very saline waters, or they have a bad smell, e.g., of H2S. So nature has its safety measures, and tasty water is nonhazardous. The danger of manmade pollution is that poisonous materials will reach the water with no accompanying bad taste or smell to warn us. 

Shock-sensitive, detonable compounds (such as sodium azide, dry picric acid) or extremely poisonous materials (such as cyanides, osmium tetroxide, cacodylic acid, tetrodotoxin, picrotoxin, ricin) should be stored in locked cabinets. DEA-regulated substances (e.g., pentobarbital, phenobarbital)... 

DOT CLASSIFICATION Forbidden SAFETY PROFILE A poisonous material. A very shock-, heat-, and friction-sensitive priming explosive. It has detonated spontaneously when dry. Explodes when heated to 311°. Upon decomposition it emits very toxic fumes of NOx and Pb. See also LEAD COMPOUNDS, NITRATES, and EXPLOSIVES, HIGH. 

DOT CLASSIFICATION 8 Label Corrosive SAFETY PROFILE A very poisonous material that is also corrosive to the eyes, skin, and mucous membranes. Violent reaction with water. Vigorous reaction with phosphorus. When heated to decomposition it emits ver " toxic fumes of CL and SOx. See also CHLOROSULFONIC ACID. 

A second description, equally graphic, further describes the hazards that Frankland and other chemists faced when working with such air-sensitive poisonous materials (98) ... 

Laboratory personnel intending to use phosgene should be fully acquainted with its toxicity and reactivity, and the protective measures associated with this particular type of poisonous material. In addition, the workers colleagues should be familiar with the hazards and the necessary rescue and first aid procedures. 

Poisons and raw materials for poison are rarely sold in stores, so an assassin who wants to be assured of pure ingredients must often go looking for them at the source. This can be as simple as a walk to the local greenhouse or a difficult break-ing-and- entering. It takes about 10 minutes per DC point of the poison to find a large enough amount of common poisonous materials to use, be it animal, vegetable, or mineral. 

A safety issue arises in conjunction with the use of recycled materials that come into contact with foods and beverages. The concern here is whether the original containers were used to store poisonous materials. 

Pharmacology/toxicology. The science of drugs and poisonous materials (respectively) and their effects on the body. Studies in these areas include diet and nutrition, overdoses, and vitamin deficiencies. 

For example, suppose that the poison is brought into contact with the catalyst pellet as a contaminant in the reactant stream flowing steadily in the reactor. Then the amount of poisoning material available is directly proportional to time.
