Let us summarise the important points that we have understood about the radiation and chemical hazards in this unit. The radiations, causing severe hazards like cancers, mutations, some skin problems are divided into ionising and nonionising types. The examples of non ionising radiations are ultraviolet, lasers etc. which are responsible for eye and skin damages mainly, a, P and y radiations are the main in ionising type. These radiations damage cells depending upon their penetration power. Use of goggles and gloves and proper storage are few of the precautionary measures to be taken to avoid any radiation hazard.
Another hazard very common mostly in chemical laboratories is in the storing and handling of chemicals which are toxic and explosive in nature. The hazardous chemicals are generally poisonous, explosive and flammable type. There are regulations which classify these chemicals into different categories. The precautions should be strictly followed while storing and handling them. The transport of these materials is also to be done carefully. A laboratory staff should be well aware of use of fume cupboards and other safety devices to prevent any hazard due to dangerous chemicals.
