LABORATORY SAFETY Why worry about lab safety LABORATORY SAFETY Why worry about lab safety? Though most labs we do in science have no safety issues, some do require the use of chemicals and/or materials that could be dangerous. In order to truly understand science we must perform experiments in class.

Chemical Hazard Label MSDS Classroom Procedures LABORATORY SAFETY Chemical Hazard Label MSDS Classroom Procedures

NFPA CHEMICAL HAZARD LABEL FLAMMABILITY HEALTH REACTIVITY (STABILITY) SPECIAL

NFPA CHEMICAL HAZARD LABEL Least Serious 4 Most 4 2 3 4 Flammable vapor which burns readily Substance is stable

NFPA CHEMICAL HAZARD LABEL Burns readily. Diborane May detonate with heat or ignition. Severe health risk. Avoid water.

NFPA CHEMICAL HAZARD LABEL Complete Label for Phosphine

MSDS Material Safety Data Sheet On file for all purchased chemicals. Includes all information shown on a chemical label and more. Different formats are used by different chemical companies.
