Your
exhibit cannot have anything which could be hazardous to public
display. This includes:
-live
disease-causing organisms which are pathogenic to man or other
live vertebrates.
-microbial cultures and fungi, live or dead, including unknown
specimens.
-food, either human or animal.
-syringes, pipettes or similar devices.
-any flames, open or concealed.
-highly flammable display materials.
-dangerous chemicals including caustics, acids, and mercury.
-highly combustible solids, fluids, or gases. Inert substances must
be used if
such materials are required for display.
-tanks which have contained combustible gases, including butane and
propane,
unless they have been purged with carbon dioxide.
-operation of a Class III or Class IV laser.
Proper
attention to safety is expected of all science fair participants,
including compliance with the following:
-any
exhibit producing temperatures exceeding 100 degrees centigrade (212
degrees
Fahrenheit) must be adequately insulated from its surroundings.
-batteries with open top cells are not permitted. Other types of
batteries may be used for
electric power.
-high
voltage equipment must be shielded with a grounded metal box or cage to
prevent accidental contact.
-large
vacuum tubes or dangerous ray-generating devices must be properly
shielded.
-high
voltage wiring, switches and metal parts must be located out of reach of
observers and designed with an adequate overload safety factor.
-electric circuits for 110-colt AC must have an Underwriters
Laboratories-approved
cord of proper load-carrying capacity, which is at least six feet long
and equipped
with a standard grounded plug.
-all wiring must be properly
insulated. Nails, tacks, or noninsulated staples must not be used to
fasten wiring.
-bare
wire and exposed knife switches may be used only on circuits of 12 volts
or less;
otherwise standard enclosed switches are required.
