3.2 Applications

The Quasar 950/960 SafEye system can be used to monitor toxic gas
concentration in various applications, such as:
• Petrochemical, pharmaceutical, and other chemical storage and production
areas
• Toxic chemical storage sites and hazardous waste disposal areas
• Detection of H
pipelines, refueling stations, and fuel storage facilities
• Transportation depots and shipping warehouses of solvents (aromatic and
polymers origin), degreasing and cleaning solvents
• Styrene monomer, polymers, and plastic industries
• Ammonia production facilities, storage, and transportation
• Air conditioning, refrigeration, and agriculture application areas for ammonia
and derivatives
• Semiconductor industry, in which ammonia concentration monitoring is
required

3.3.4 Detected Gases

The following toxic gases and vapors are detected by the UV SafEye models
according to their unique spectral absorption in the UV solar blind range:
• SafEye 960: Hydrogen Sulfide (H
characteristic smell of rotten eggs. It is perceptible in air at concentrations of
0.001–0.1ppm, with a sweetish taste, and a TLV-TWA of 10ppm.
H S is heavier than air and very dangerous to humans, causing collapse,

coma, or death from respiratory failure within a few seconds of inhalation.
Early detection of H
prevent its toxic influence.
