Fog and Haze

​The use of fog machines inside any UHD building is not allowed except:

  • In a laboratory setting under proper ventilation

  • During a theatrical performance in either the O’Kane Theatre or Wilhelmina Cullen Robertson Auditorium

Fog and haze present a number of safety concerns.

  • High concentrations of fog can obscure the visibility of exit signs, exit doors and pathways, which is prohibited by Fire Codes

  • Fog at high concentrations can set off smoke detectors that are in the HVAC system, activate the fire alarm and disrupt the event

  • Glycol solutions used to produce fog may cause irritation of eyes, nose and throat as well as allergic reactions at high concentrations

As a result of these and other safety concerns, the use of any machine, device or chemical to create fog, foam or a haze-like visual effect, is limited by the UHD EHS Office.  The limited use during a theatrical performance and for special events will be allowed with the following precautions:

  • A safety plan and with fire attendant details must be submitted to the UHD EHS Office for approval

  • The EHS Office must be notified of the intended use of fog or haze at least seven days prior to the event

  • The Facilities Management Department will deactivate smoke detectors in the immediate area during event
