Recognize the Hazards

The first principle of laboratory safety is to recognize the hazards of chemicals, equipment, and procedures.

Tips

  • Use Safety Data  Sheets (SDSs) to identify Globally Harmonized System (GHS) hazards of the chemicals you will be using. These  include physical, health, and environmental hazards. The main hazard categories are flammables, explosives, corrosives, oxidizers, irritants, and toxicants.
  • Understand the nature of the hazard (its chemistry and/or toxicological/biological effects).
  • Identify the most important physical hazards from equipment, conditions, and procedures. These include electrical and mechanical hazards and high or low temperature or pressure.

Establishing a Safety Culture in a School Setting

The first step toward recognizing hazards is awareness of safety to begin with.

It's the teacher's responsibility to instill a general understanding of safety in the laboratory. We recommend adopting an appropriate set of safety rules and guidelines for students that is manageable and specific for a particular class and setting.

In addition to providing students with a set of guidelines, it's also important to have them (and their parents or guardians) sign a safety contract.
