Although attention is usually concentrated on chemical hazards in laboratories, consideration must be given to the safe use of laboratory equipment. Equipment in the laboratory must be set up and operated properly to ensure that accidents are minimized. Cuts and burns from handling glassware are among the most common sources of laboratory accidents. Breaking glassware may cause a chemical spill and possible injury.
Chemicals exploding in glassware can send fragments of glass flying into the laboratory.
Vacuum systems may implode, sending flying glass and chemicals across the room. Flammable vapors contacting sparking electrical equipment may cause an explosion. Laboratory workers may be electrocuted if they handle electrical equipment improperly. The following safety procedures should reduce the potential for accidents in laboratories. Inexperienced users should receive training in the proper handling of glassware, especially with systems that present unusual risks such as excess pressure or vacuums.
