Why beams show
ANSI E1.5 defines fog as an aerosol that reflects light. That is why a beam passing through it becomes visible.
Built-in lights
Some fog machines have lights built in. What they do, and how they are controlled, is in the maker's manual.
Controlling it with the show
Many lighting rigs use DMX. DMX control, explained
Lasers
Lasers have their own safety rules. We do not cover them. Ask the venue and the laser operator.

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.
