- In order to protect the public, no explosive, highly
flammable, corrosive or highly poisonous materials may be
brought to the fair. All chemicals must be protected so
that there will be no possibility of damage to
spectators, neighboring exhibitors, etc. Use of rocket
fuels, armed rockets and explosives of any kind is
prohibited. This is very important in the crowded
conditions at the science fair.
- Due to the fire hazard, there can be no open flame,
torch, or burner. Electrical heating units must be well
protected and must not be near the front edge of the
- Projects dealing with radiation, either from x-rays or
radioactive materials must present no hazard to the
- Plants must be properly cared for. Provision should be
made to prevent offensive odors.
- No pathogenic cultures may be exhibited.
- Molds and bacterial cultures must be covered carefully
and sealed tightly at all times.
- Hypodermic needles and syringes must not be left on
display. Any exhibit, which includes them, will be
automatically disqualified and removed from the fair.
- All moving parts of machines must have protective
covering. Watch particularly for vacuum pumps.
- Push buttons and levers must be securely mounted on
exhibits. They must not be attached to tables or walls.
- Material and construction must be durable. All movable
parts must be firmly attached. Power-driven movable parts
must be protected with guards.
- All electrical apparatus must be constructed according to
standard electric safety laws. If you are in doubt,
consult a competent electrician.
- All exhibits which require house current for operation or
illumination must be designed for operation on
alternating current at 110-115 volts. If batteries are
used, they should be storage batteries to insure
continuity of operation. Dry cell batteries may be used
if they are frequently renewed.
- Doorbell push buttons must not be used to control 110-115
volt apparatus. Use toggle or push-button switches
designed for the proper load. Non-insulated switches,
such as knife switches, will not be permitted.
- All wiring, switches and metal parts carrying current
must be completely enclosed by barriers that will
positively prevent observers from reaching into the
exhibit and receiving an electrical shock. Both front and
back of display must be so enclosed. All chassis should
- All electrical joints must be properly secured and
- Nails, tacks and uninsulated staples must not be used for
fastening wires. Use porcelain and other suitable types
- All wire used in construction of exhibits must be
selected and insulated for voltage in use. There must not
be any exposed wires.
- All capacitor banks must have short-out provisions.
- All solvents must be in proper containers.
- All pressure vessels should have relief valves.
- All laser beams must be contained and pulsed electrical
