The Clean Air Acts lists 187 hazardous air toxics that are regulated. These air toxics can cause cancer and other serious health effects. There are other gases that are flammable, corrosive or otherwise defined as noxious odorants or cause irritation. Real-time identification will quickly render information as to possible source and remedy.
There are four general areas of gas monitoring for airborne exposures: breathing zone, workplace exposure, indoor air monitoring—including institutions and multi-tenant residences and area. It is often cumbersome to fit personnel with monitors if the contaminants are intermittent and also cost-prohibitive to continuously monitor areas where contaminant gases are not routine. Portable, direct-read instrumentation, operated by technicians, provide a readily-available cost-effective solution for immediate on-site detection and identification of hazardous gases.
