National Institute for Occupational Safety and Health (NIOSH) Recommended Exposure Limit (REL): 50 ppm, 240 mg/m3 TWA
Health Factors
NIOSH Immediately Dangerous To Life or Health Concentration (IDLH): 1800 ppm [LEL]
Potential symptoms: Irritation of eyes, nose, throat, skin; cough, sore throat; corneal damage; dry skin, dermatitis; in animals: narcosis, liver damage
Health Effects: Irritation-Eye, Nose, Throat, Skin---Moderate (HE15); Cumulative kidney damage (HE3); Potential narcosis (HE8)
Affected organs: Eyes, skin, respiratory system, CNS, liver
Note:
The IDLH is 10% of the lower explosive limit (1.8%). Above 58ºC, explosive vapor/air mixtures may be formed.
