3. Hazards Identification
EMERGENCY OVERVIEW
Corrosive and irritating to the eyes, skin and mucous membranes. Inhalation may result in chemical
pneumonitis and pulmonary edema.
ROUTE OF ENTRY:
Skin Contact Skin Absorption Eye Contact Inhalation Ingestion
Yes No Yes Yes No
MSDS: G-39
Revised: 6/7/96 Page 1 of 6
PRODUCT NAME: HYDROGEN BROMIDE
HEALTH EFFECTS:
Exposure Limits Irritant Sensitization
Yes Yes No
Teratogen Reproductive Hazard Mutagen
No No No
Synergistic Effects
Other agents that irritate the respiratory system
Carcinogenicity: -- NTP: No IARC: No OSHA: No
EYE EFFECTS:
Corrosive and irritating to the eyes. Contact with the liquid or vapor causes painful burns. Burns to the eyes
result in lesions and possible loss of vision.
SKIN EFFECTS:
Corrosive and irritating to the skin and all living tissue. Hydrogen Bromide hydrolyzes very rapidly, yielding
hydrobromic acid. Skin burns and mucosal irritation are like that from exposure to volatile inorganic acids.
Toxic level exposure to dermal tissue causes acid-like burns and skin lesions resulting in early necrosis and
scarring. Hydrobromic acid burns exhibit severe pain, redness, possible swelling and early necrosis.
INGESTION EFFECTS:
None known. Ingestion is unlikely.
INHALATION EFFECTS:
Corrosive and irritating to the upper and lower respiratory tract and all mucosal tissue. Symptoms include
lacrimation, cough, labored breathing and excessive salivary and sputum formation. Excessive irritation of the
lungs causes acute chemical pneumonitis and pulmonary edema, which could be fatal. Chemical pneumonitis
and pulmonary edema result from exposure to the lower respiratory tract and deep lung. Residual pulmonary
malfunction might occur.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE:
Individuals with impaired pulmonary function may be at increased risk from exposure.
NFPA HAZARD CODES HMIS HAZARD CODES RATINGS SYSTEM
Health: 3 Health: 3 0 = No Hazard
Flammability: 0 Flammability: 0 1 = Slight Hazard
Reactivity: 0 Reactivity: 0 2 = Moderate Hazard
3 = Serious Hazard
4 = Severe Hazard
4. First Aid Measures
EYES:
PERSONS WITH POTENTIAL EXPOSURE SHOULD NOT WEAR CONTACT LENSES. Flush
contaminated eyes with copious quantities of water. Part eyelids to assure complete flushing. Continue for a
minimum of 30 minutes. Seek immediate medical attention.
SKIN:
Remove contaminated clothing as rapidly as possible. Flush affected area with copious quantities of water.
Seek immediate medical attention.
INGESTION:
MSDS: G-39
Revised: 6/7/96 Page 2 of 6
PRODUCT NAME: HYDROGEN BROMIDE
None required.
INHALATION:
PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF OVEREXPOSURE. RESCUE
PERSONNEL SHOULD BE EQUIPPED WITH SELF-CONTAINED BREATHING APPARATUS. Victims
should be assisted to an uncontaminated area and inhale fresh air. Quick removal from the contaminated area is
most important. Unconscious persons should be moved to an uncontaminated area, and if breathing has stopped,
administer artificial resuscitation and supplemental oxygen. Further treatment should be symptomatic and
supportive. Assure that mucus or vomited material does not obstruct the airway by positional drainage. Delayed
pulmonary edema may occur. Keep patient under medical observation for at least 24 hours.

FIRE AND EXPLOSION HAZARDS:
None.
EXTINGUISHING MEDIA:
Suitable for surrounding materials. Reacts with moisture yielding dense, acid fumes.
6. Accidental Release Measures
Evacuate all personnel from affected area. Use appropriate protective equipment. If leak is in user鈥檚 equipment,
be certain to purge piping with inert gas prior to attempting repairs. If leak is in container or container valve,
contact the appropriate emergency telephone number listed in Section 1 or call your closest BOC location.
7. Handling and Storage
Electrical Classification
Nonhazardous.
Most metals corrode rapidly with wet hydrogen bromide. Copper-nickel alloys and copper-tin alloys as well as
tainless steel and nickel-chromium alloys offer best resistance to HBr corrosion. Kel-F 庐 and Teflon 庐 are best
for gasketing materials. Do not use Buna S 庐, Buna N 庐, or Neoprene.
Use only in well-ventilated areas. Valve protection caps must remain in place unless container is secured with
valve outlet piped to use point. Do not drag, slide or roll cylinders. Use a suitable hand truck for cylinder
movement. Use a pressure reducing regulator when connecting cylinder to lower pressure (<400 psig) piping or
systems. Do not heat cylinder by any means to increase rate of product from the cylinder. Use a check valve or
trap in the discharge line to prevent hazardous back flow into cylinder.
Protect cylinders from physical damage. Store in cool, dry, well-ventilated areas of non-combustible
construction away from heavily trafficked areas and emergency exits. Do not allow the temperature where
MSDS: G-39
Revised: 6/7/96 Page 3 of 6
PRODUCT NAME: HYDROGEN BROMIDE
cylinders are stored to exceed 130oF (54oC). Cylinders should be stored upright and firmly secured to prevent
falling or being knocked over. Full & empty cylinders should be segregated. Use a "first in-first out" inventory
system to prevent full cylinders from being stored for excessive periods of time.
For additional storage recommendations, consult Compressed Gas Association鈥檚 Pamphlet P-1.
Never carry a compressed gas cylinder or a container of a gas in cryogenic liquid form in an enclosed space such
as a car trunk, van or station wagon. A leak can result in a fire, explosion, asphyxiation or a toxic exposure.
