All Rights Reserved. 94-4624 Chemical Hazards NFPA Chemical Hazard Label Flammables Flammable liquids and vapors are the most common fire hazard in the laboratory. Fires need air, flammable gas or vapor and an ignition source. Carcinogens Any chemical that can cause cancer. This category includes known or suspected carcinogens such as formaldehyde and benzene among many others. Corrosives Corrosives are chemicals such as strong acids, bases and metallic salts that cause severe chemical burns to living tissue at the site of contact. Corrosive chemicals can affect the skin, eyes, respiratory tract and gastrointestinal tract. Explosive Substances Explosive substances are chemicals that decompose at an extremely rapid and violent rate causing an explosion by producing large volumes of gas. Examples of such substances include ammonium nitrate and isopropyl ether among others. Oxidizers Oxidizers are chemical compounds which have the ability to act as an oxygen source and are especially hazardous during a fire. Such substances present a fire and explosion risk when in contact with organic or combustible materials. Sensitizers/Irritants Sensitizers and Irritants are chemicals that cause irritation and inflammation to living tissue with repeated use. Solvents Solvents are considered fire hazards. Examples include acetone, diethyl ether and ethanol. Precautions include storage in a flammable liquid cabinet and usage under a fume hood. Toxic Chemicals These are chemicals that affect key life processes and can cause death or permanent injury to humans or animals. Water Reactive Chemicals “Water-reactive” chemicals react with water to release a gas that is either flammable or presents a health hazard. Examples include aluminum powder, magnesium powder, sodium, potassium and zinc powder among many others. The National Fire Protection Association (NFPA) has developed a color coded, numerical system for representing the health, flammability and reactivity hazards of chemicals. The degree of hazard is rated from 0 to 4.

How does a chemical enter the body? Inhalation and dermal contact are the primary routes of chemical exposure in the laboratory. To prevent inhalation exposures, be sure to work in a laboratory with good ventilation and to use a chemical fume hood. Wearing appropriate chemical protective gloves and clothing can prevent dermal contact. Following good hygiene habits, such as regular hand washing and using tongs or other tools to pick up sharp objects, can prevent exposure through ingestion or injection. Regardless of the way a chemical gets into the body, once in the bloodstream the chemical is carried to all parts of the body causing potential harm. Inhalation The easiest, most common way for toxic chemicals to enter your body is through inhalation of gases, vapors, mists, dusts and fumes. Once inhaled, poisonous chemicals can be absorbed into the lungs and then into the bloodstream. Once in the blood, these chemicals are transported to all vital organs causing serious harm. Dermal Exposure Although the skin is an effective barrier for many chemicals, it is the second most common route by which select chemicals can enter the body and into the blood stream. Chemicals can also enter the body much more readily through cuts, punctures or scrapes of the skin. In some instances, chemicals may enter by accidental injection through the skin. The degree to which a chemical penetrates the skin depends on the type. Generally, organic chemicals are much more likely to penetrate the skin than inorganic chemicals. Corrosive chemicals on the other hand will actually burn through the skin. The effects of dermal exposure to various substances can range from mild temporary discomfort to permanent damage. Ingestion Ingestion involves chemicals entering the body through the mouth. Chemical dusts, particles and mists can enter the digestive system either by swallowing contaminated mucus or by eating something with contaminated hands. Once inside the mouth, chemicals pass down the esophagus and then into the gastrointestinal (GI) tract and get absorbed into the bloodstream. lungs trachea fumes inhaled contaminated food cut in skin corrosive burn chemical enters bloodstream Masks may be worn to guard against inhaling dust and fumes. Inhaled chemicals enter the bloodstream through capillaries in the lungs. www.newpathlearning.com © Copyright NewPath Learning.

Notify your teacher of spills and clean up promptly. Wear appropriate protective equipment. www.newpathlearning.com © Copyright NewPath Learning. All Rights Reserved. 94-4626 Chemical Handling BIOHAZARD • Wear appropriate personal protective equipment before handling chemicals. • Organize stored chemicals by compatibility. Store incompatible chemicals separately. • Review the MSDS and labels for hazards associated with the substance before using it. • Be sure to use the correct chemical required for the experiment. Read the label twice. • Label containers before you transfer any chemicals. Be sure to include the name of the chemical, concentration, hazard, date and your initials. • Always use a clean spatula to remove a solid substance from a container. Never use a metal spatula when working with peroxides. Metals will decompose explosively with peroxides. • Do not touch any chemical with your bare hands. • Do not taste or smell any chemicals. • Hold containers away from the body when transferring a chemical or solution from one container to another. • Keep combustible substances away from open flames. • Always add acid to water slowly. NEVER add water to an acid. • Weigh out or remove only the amount of chemical you will need. Never return a chemical to the original container once it has been removed. • Never mix or use any chemicals that are not authorized by your teacher. • Use the laboratory chemical hood, if available, when there is a possibility of release of toxic chemical vapors, dust or gases. • Notify your teacher of any chemical spills. Clean up all spills properly and promptly as instructed by the teacher. • Dispose of chemicals as instructed by the teacher. • Use good housekeeping practices. Keep your work area clean and uncluttered. • When transporting chemicals of 250mL or more, place the immediate container in a secondary carrying container, large enough to hold the entire volume of the chemical in case of a spill. • Never handle bottles that are wet or may be too heavy for you. • Always wash hands with soap and water after completing a laboratory activity.
