Water-based fluids
ANSI E1.5 covers fogs made from water and listed glycols or glycerin. It names the components it covers, including propylene glycol and glycerin.
Oil-based fluids
HSE guidance describes oil mists made by forcing compressed air through mineral oils.
Use the named fluid
One maker's manual says to use only its water-based fog fluid, and never to add perfume, alcohol, gasoline, or any other flammables.
Health questions
We do not make health claims about any fluid. A NIOSH study of Broadway shows found that some fog ingredients could irritate or dry the eyes, nose, and throat in some people. Read the fluid's safety data sheet and label, and ask the maker.

FAQ
General information only. Follow your machine's manual and the label on any fluid. Fog and haze can set off smoke alarms and make it hard to see. Never disable an alarm. Check the venue's or building's rules before you use any effect. Dry ice can cause frostbite and gives off carbon dioxide, which can build up in low or enclosed spaces. Never touch it with bare hands, never seal it in a container, use it only with good ventilation, and keep it away from children and pets. Anyone with asthma or another breathing condition should ask a doctor before being around fog, haze, or dry ice effects.
