The poison active chemical reagents are cyanide ion (CN–), aniline (C6H5 — NH2), CC14 and halogens.
CN– ions form complex compound with hemoglobin to form cyano-hemoglobin which cannot carry oxygen to the lungs and causes death. Aniline has the same poisonous action as cyanide compound. CC14 and halogens hamper the liver and kidney.
Nature of the flammable reagents: These substances are burned easily when they come closer to flame or heat. Their point is very low and burned easily. These are kept very far from fire, heat and flame.
Nature of the injury creation reagents: These types of reagents easily can create injury in the organ of the body if they fall on that argon. Their action is very fast. They mainly harm on the skin.
