Lighting and Visual Effects

General lighting must be bright enough to allow guests or the audience to see the aisles leading to the exits.  This prevents people from tripping or falling under normal circumstances and facilitates a quick evacuation in case of an emergency.  If mood lighting is used, someone must be assigned to stay at the control panel so the lights can be turned up immediately if the fire alarm is activated.

If you plan to use unusual lighting or visual effects, you must also develop a plan that determines how

It can be accomplished in a manner that complies with the regulations and guidelines governing safe lighting.  The safety plan must be reviewed and approved by the following departments:

  • Theatre Arts Director or Technical Director if it is a theatrical production within the theater.

  • The EHS Office for all other events

Lighting equipment (especially high intensity) must be UL rated and positioned so curtains and decorations are not ignited.  Refer to the “Decorations” and “Electrical Extension and Power Cord” sections on pages 8 and 11 respectively.



The vendor must follow all safety requirements which the event sponsor should give to them prior to the event.  The safety requirements are as follows:

  • Equipment must be 2 Hertz, with a Flicker rate of 4 flashes per second or less, interrupted and synchronize multiple strobes

  • The EHS Office highly recommends the use of a licensed operator for the strobe equipment

“Strobe lighting will be used in this production. Those with known sensitivity to strobe light should avoid viewing the (specify the time period or portion) of this show.”

Also mention if there are any other unusual effects that could startle or disturb the audience, such as gunfire.
