From the DJs experience as a hockey player. My personal suggestion of focus is head protection (just ask my DJ assistant and check out his scars)! Second focus would be elbows and hands. Don’t hesitate to use the boards for balance!

 

Class 3B Lasers
Lasers in this class may cause damage if the beam enters the eye directly. This generally applies to lasers powered from 5–500 mW. Lasers in this category can cause permanent eye damage with exposures of 1/100th of a second or less depending on the strength of the laser. A diffuse reflection is generally not hazardous but specular reflections can be just as dangerous as direct exposures. Protective eyewear is recommended when direct beam viewing of Class IIIb lasers may occur. Lasers at the high power end of this class may also present a fire hazard and can lightly burn skin. Many laser pointers at this output level are now available in this category. Source: Wikipedia
Our projector will always display a diffused beam so there is no great risk but DO NOT LOOK AT THE PROJECTOR! This particular warning is a required posting by our entertainment partners. Basically if the projector were able to focus the entire beam in to one single point, then it would be a risk factor however due to the nature of the design of the unit, it will never do that.

Theatrical Glycol-Based Fog
Some possible side effects may include:
Irritation of mucous membranes such as the eyes and the respiratory tract associated with extended peak exposure to theatrical fog.
Short-term exposure to glycol fog was associated with coughing, dry throat, headaches, dizziness, drowsiness, and tiredness. 
Long-term cumulative exposure to smoke and fog has a potential to create chest tightness and wheezing and / or reduced lung function. Exposure to glycol-based fogs are potentially associated with acute and chronic adverse effects on respiratory health.

Our glycol-based fogs meet or exceed the standards of The Entertainment Services and Technology Association (ESTA) however it is fully the responsibility of guests to determine if this risk is a concern. We do not reccomend children under 16 attend DJ Skates. If you or anyone you see might be experiencing any of the above symptoms, please exit the rink area immediately and inform a staff member.

Strobe Lighting & Moving (Intelligent) Lighting
Stroboscopic (‘strobe’) lighting may cause susceptable viewers to have an epileptic attack or otherwise damage their health. Anyone at risk for this condition should not attend DJ Skates. Our strobe lighting is programmed to only flash at a maximum of 3 cycles in any given second and is not constant. International standards state that frequencies faster than five cycles per second is where a potentially harmful effect is increased.
