Scotch Mist^® is non-toxic and produces no toxic products during the fire fighting process. The oxygen reduction properties of Scotch Mist^® occur locally around the fire and therefore present no hazard to personnel.

The ability of Scotch Mist^® to rapidly reduce temperatures and to wash out post-combustion smoke makes it the ideal alternative to Halon for occupied areas.  Indeed, the US-EPA and NFPA have both carried out research which shows that water mist systems present no hazard whatsoever to people when used as a fire suppression agent.

However, during a discharge, Scotch Mist^® creates a fine water mist which, although safe in itself, may cause minor body and respiratory discomfort whilst, at the same time, reducing visibility.  All staff working in areas protected by Scotch Mist^® (or any proprietary water mist system) should therefore be adequately trained in its use and be made aware that prompt evacuation in the event of an alarm is recommended.
