Atmospheric furnishings generated application baptize and dry ice or aqueous nitrogen can present asphyxiation or breath hazards. Both carbon dioxide and nitrogen displace accustomed air and the oxygen it contains, creating a accident of attenuate anoxia (lack of oxygenation) for bodies alive in these atmospheres. Adequate blast is capital to ensure that artists and technicians are amidst by breathable air. Carbon dioxide has the added hazard of interfering with the accustomed breath reflex, which is astute to carbon dioxide levels in the air. Nitrogen has no aftereffect on the breath reflex, but this creates its own hazard in that a being breath authentic nitrogen can lose alertness from abridgement of oxygen after any apocalyptic symptoms.
Fog produced with aqueous air does not present the hazards of carbon dioxide or aqueous nitrogen because the aqueous air has the aforementioned agreement as accustomed atmospheric air (including the aforementioned akin of breathable oxygen).
Fog machines which accomplish their furnishings alone application water, such as accelerated or pressurized technology, affectation no appropriate bloom risks, about it should be acclaimed that "water based" fog aqueous does accommodate glycol.
A cardinal of studies accept been appear on the abeyant bloom furnishings presented by acknowledgment to glycol based affected fogs and bogus mists.
Two studies, a Bloom Hazard Evaluation completed in 1994 by the National Institute for Occupational Safety and Health,3 and addition one in 2000 by the Department of Community and Preventative Medicine at the Mount Sinai School of Medicine and ENVIRON;4 both able for Actors Equity and the League of American Theatres and Producers, focused on the furnishings on actors and performers in Broadway musicals. The cessation of both studies was that there was affliction of close membranes such as the eyes and the respiratory amplitude associated with continued aiguille acknowledgment to affected fog. Acknowledgment guidelines were categorical in the 2000 abstraction that, it was determined, should anticipate actors from adversity adverse appulse to their bloom or articulate abilities.
Another abstraction 5 focused on the use of affected fog in the bartering aerodynamics industry for emergency training of agents in apish blaze conditions. This abstraction additionally begin eye and respiratory amplitude irritation.
In May 2005, a abstraction appear in the American Journal of Industrial Medicine,6 conducted by the School of Environment and Bloom at the University of British Columbia, looked at adverse respiratory furnishings in aggregation associates on a advanced array of ball venues alignment from alive theatres, concerts, television and blur productions to a video arcade. This abstraction bent that accumulative acknowledgment to mineral oil and glycol-based fogs were associated with astute and abiding adverse furnishings on respiratory health. This abstraction begin that concise acknowledgment to glycol fog was associated with coughing, dry throat, headaches, dizziness, drowsiness, and tiredness. This abstraction additionally begin abiding acknowledgment to smoke and fog was associated with both concise and abiding respiratory problems such as chest binding and wheezing. Personnel alive abutting to the fog machines had bargain lung action results.
The Ball Services and Technology Association (ESTA) has aggregate a accepted for affected fogs or bogus mists compositions for use in ball venues that "are not acceptable to be adverse to contrarily advantageous performers, technicians, or admirers associates of accustomed alive age, which is 18 to 64 years of age, inclusive."7 This accepted was based primarily (though not exclusively), aloft the allegation of a address commissioned for ESTA by the Cohen Group8 and applies alone those fog aqueous compositions that abide of a admixture of baptize and glycol (so alleged "water based" fog fluid).
Short appellation acknowledgment to glycol fog can be associated with headaches, dizziness, blackout and tiredness. Long appellation acknowledgment to smoke and fog can be accompanying to high airway and articulation symptoms. Continued (multi-year) acknowledgment to smoke and fog has been associated with both concise and abiding respiratory bloom problems. Efforts should be fabricated to abate acknowledgment to affected smoke to as low a akin as possible. The use of agenda furnishings in column assembly on blur and television sets can be advised a safer practise than application affected smoke and fog during filming,9 although this is not consistently practical.
