an individual holding a cdc training certificate for the handling of small animals can work with toxic chemicals in an ld50 assay. in addition, if the chemical is not a routine laboratory or industrial chemical, that individual may be a competent toxicologist, pharmacologist, or industrial toxicologist, depending on the nature of the work. in some cases, veterinary staff or medical personnel may also be involved. these individuals are not expected to have extensive training in regulatory compliance or laboratory design and conduct, but the scope and purpose of the work must be well defined. background knowledge in these areas is always a good idea.

the procedure outlined here describes some general hazards associated with handling chemicals in laboratory settings. each laboratory has additional hazards that are unique to its particular environment. laboratories are expected to adopt protocols and procedures designed to reduce hazard risk in the laboratory, and they should design and organize their facilities so that hazardous chemicals, material, or situations are not present or created on site. all personnel involved in laboratory work should follow procedures and protocols designed to reduce the risk of chemical exposure or release. in addition to industrial hygiene practices, regulatory practices and guidelines that are specific to the handling of hazardous chemicals should be followed. facilities and equipment used for handling chemicals or for storing hazardous materials should be well maintained and properly designed. suppliers of laboratory chemicals and equipment should be contacted to ensure that they have procedures and protocols to reduce chemical exposure for personnel.

the health effects of hazardous substances vary greatly, and may be related to the amount or duration of exposure, the concentration of the chemical, the conditions under which the substance is handled, and the person’s sensitivity to the substance. in general, the following health effects occur after exposure: skin irritation (redness, itching, or burning) and eye irritation. this occurs at the site of contact or after inhalation. the skin and eye are the most sensitive of the body’s tissues and are directly exposed to toxic substances. the eyes and skin of animals can also be affected when they are exposed to a chemical accidentally. skin sensitization (a delayed type of sensitization) and allergic contact dermatitis. this is an allergic reaction that may occur after a person comes in contact with a chemical, even though the person has no previous exposure to that chemical. sudden death. this may occur if a person is exposed to a toxic substance that affects the heart or brain. inhalation of or contact with a corrosive gas or liquid can cause pulmonary edema. cancer. a substance that causes cancer in animals, or in a person after a long latency period, is called a carcinogen. a carcinogen may also be a teratogen (that is, it can cause birth defects). mutagenic (causes genetic changes). a substance that induces mutations is called a mutagen. reproductive toxicity. a substance that interferes with normal reproductive processes is called a reproductive toxin. carcinogenicity. a substance that causes cancer in animals is called a carcinogen. teratogenicity. a substance that can cause birth defects is called a teratogen. a teratogen may also be a carcinogen.
