Minimum Safety Guidelines
for Chemical Demonstrations
Chemical Demonstrators Must:
- Know the properties of the chemicals and the chemical reactions involved in all demonstrations presented.
- Comply with all local rules and regulations.
- Wear appropriate eye protection for all chemical demonstrations.
- Warn the members of the audience to cover their ears whenever a loud noise is anticipated.
- Plan the demonstration so that harmful quantities of noxious gases (e.g., NO2, SO2, H2S) do not enter the local air supply.
- Provide safety shield protection wherever there is the slightest possibility that a container, its fragments, or its contents could be propelled with sufficient force to cause personal injury.
- Arrange to have a fire extinguisher at hand whenever the slightest possibility of fire exists.
- Not taste or encourage spectators to taste any non-food substance.
- Not use demonstrations in which parts of the human body are placed in danger (such as placing dry ice in the mouth or dipping hands into liquid nitrogen).
- Not use "open" containers of volatile, toxic substances (e.g., benzene, CCl4, CS2, formaldehyde) without adequate ventilation as provided by fume hoods.
- Provide written procedure, hazard, and disposal information for each demonstration whenever the audience is encouraged to repeat the demonstration.
- Arrange for appropriate waste containers for and subsequent disposal of materials harmful to the environment.
