General Description

OSHA IMIS Code Number: 0390

Chemical Abstracts Service (CAS) Registry Number: 7726-95-6

NIOSH Registry of Toxic Effects of Chemical Substances (RTECS) Identification Number: EF9100000

Department of Transportation Regulation Number (49 CFR 172.101) and Guide: 1744 154

Exposure Limits

OSHA Permissible Exposure Limit (PEL):

General Industry: 29 CFR 1910.1000 Z-1 Table -- 0.1 ppm, 0.7 mg/m3 TWA

Maritime: 29 CFR 1915.1000 Table Z-Shipyards -- 0.1 ppm, 0.7 mg/m3 TWA

American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Value (TLV): 0.1 ppm, 0.66 mg/m3 TWA; 0.2 ppm, 1.3 mg/m3 STEL

National Institute for Occupational Safety and Health (NIOSH) Recommended Exposure Limit (REL): 0.1 ppm TWA; 0.3 ppm STEL

Health Factors

NIOSH Immediately Dangerous To Life or Health Concentration (IDLH): 3 ppm

Potential Symptoms:
Dizziness, headaches; eye irritation, lacrimation; epistaxis (nosebleed); bronchospasm, shortness of breath, coughing, chest pain or tightness; feeling of oppression; pulmonary edema; pneumonitis; reactive airways dysfunction syndrome (RADS); abdominal pain; diarrhea; measle-like eruptions; skin burns

Health Effects: Irritation-Eye, Nose, Throat, Bronchi, Skin-Marked (HE14) Acute lung damage/edema (HE11)

Affected Organs: Respiratory system, eyes, skin, CNS

Notes: 1) RADS is the persistence or recurrence of asthma-like symptoms lasting long after the exposure. 2) The bromination of tyrosine to form 3-bromotyrosine in lung proteins by eosinophil peroxidase is reportedly increased in asthmatics, but its relevance to effects of bromine inhalation is unknown. 3) A study of chemical burns in 173 patients admitted to a hospital burn unit indicated bromine and its compounds to be the most frequent cause.
