Health Effects
Nitric oxide has only modest toxicity, but it forms the much more toxic nitrogen dioxide (OSHA PEL Ceiling 5 ppm) on contact with atmospheric oxygen
RTECS Description: Mutagen
Carcinogenicity: IARC/NTC Not listed as carcinogenic.
Exposure Limits:
ACGIH: TLV = 25 ppm
NIOSH REL = 25 ppm
IDLH = 100 ppm

Steri-Trac® NO Monitor
Availability: Special Order
Specifications:*
Range: 0 – 100 % v/v
Resolution: 1 % v/v
Temp Range: -20 to +50 oC

Properties and Applications:
Nitric oxide is paramagnetic and is readily oxidized to nitrogen dioxide and constitutes one of the components of the common pollutant NOx gases. Nitric oxide is used in the synthesis, especially of nitric acid and it has found limited medical use as a vascular dilator and finds widespread application in biology.
