New Fog machine user help

[teenypops]

I don't know if this has already been covered, I did serach, but couldn't find exactly my query.

I have been requested to use a fog machine at a kids party.

I do have a Maplin (ProSound I think) smoke machine and have used it outside for a halloween effect, but not indoors.

I have asked my client to check with the venue that they are OK with the use, but I am still concerned with the potential of setting off any alarms.

Does anyone have any advice on this, is there a certain type of machine or liquid that is lees likely to activate smoke alarms.

Thanks Guys... in advance

If the venue give you permission then so be it, If it sets off the alarms you have covered your back, Make out some sort of indemnity form for the venue to sign relinquishing you of all responsibility of the alarms. I find most venues know if you can use smoke or not.

Check whether the venues smoke alarms are 'heat rise' or 'particulate' sensors. If they are heat rise then all's well as smoke/haze will not generally set them off. I say generally because I believe there is a hybrid sensor available although it doesn't seem to be commonly used. If particulate sensors are fitted then you've got more of a problem and ALL hazers/foggers have the potential to set off the alarms, after all they're doing the job they were designed to do... detecting particulate in the air.

You could ask the venue if you could run a trial on an evening when there's nothing going on and see what happens. I wouldn't recommend doing this if there's a direct link to a monitoring station unless you warn them of what you're doing. It may also be possible to ask the venue to isolate the local sensors, but if you're doing that you'll have to mitigate the risks and probably appoint a fire officer for the evening.

Most newer function venues tend to have heat rise sensors fitted. Particulate sensors are responsible for the demise of the use of haze in venues. Generally a very light haze won't set them off, but rather than risk it venues tend to blanket ban all types of haze and fog.

As previously mentioned, best advice is to ask the venue management and go with what they say.

Cheers

Thanks peeps that is really helpful, I think I will definitely go with the indemnity form option and suggest a test run.
