Product: Red Gauge Glass Liquid P-4894-D Date: September 2004
EFFECTS OF A SINGLE (ACUTE) OVEREXPOSURE:
INHALATION璙apor irritates the lungs and upper respiratory tract, producing coughing, breathing
difficulty, nausea, headache, and abdominal pain. May depress the central nervous system, producing
tremors, narcosis, incoordination, and unconsciousness. May also damage the liver and kidneys, and
cause pulmonary edema (fluid in the lungs).
SKIN CONTACT璏ay irritate the skin causing pain and a burning sensation. Harmful amounts of
material may be absorbed if skin contact is prolonged or widespread.
SWALLOWING璏ay irritate the mouth and throat, causing nausea, headache, vomiting, abdominal
pain, dizziness, tremors, stupor, and coma. May also damage the liver and kidneys.
EYE CONTACT璏ay irritate the skin causing pain, redness, and excessive tearing. Can cause
permanent eye injury.
EFFECTS OF REPEATED (CHRONIC) OVEREXPOSURE: May cause liver and kidney damage.
OTHER EFFECTS OF OVEREXPOSURE: At high concentrations, may cause cardiac arrhythmias or
arrest due to sensitization of the heart to adrenaline and noradrenalin.
MEDICAL CONDITIONS AGGRAVATED BY OVEREXPOSURE: Inhalation may aggravate
asthma and inflammatory or fibrotic pulmonary disease. The irritating properties of the material may
aggravate an existing dermatitis. Methylene bromide is metabolized to carbon monoxide and bromine,
raising blood levels of carboxyhemoglobin. The higher concentration may be detrimental to those with
existing anemia or cardiovascular disease.
SIGNIFICANT LABORATORY DATA WITH POSSIBLE RELEVANCE TO HUMAN HEALTH
HAZARD EVALUATION: Sudan red dye has been shown to cause cancer in experimental animals
(NTP), indicating that it is a potential human carcinogen. Acetylene tetrabromide has been shown to be
mutagenic to bacteria.
CARCINOGENICITY: The IARC lists Sudan II (CAS 3118-97-6) as Group 3, unclassifiable as to
carcinogenicity to humans.
4. First Aid Measures
INHALATION: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult,
qualified personnel may give oxygen. Call a physician.
SKIN CONTACT: Immediately flush skin with plenty of water for at least 15 minutes while removing
contaminated clothing and shoes. Wash clothing before reuse; discard shoes. Call a physician.
SWALLOWING: Have victim, if conscious and alert, rinse mouth with water. Give at least two glasses
of milk or water. Do not induce vomiting. Never give anything by mouth to an unconscious, convulsive,
or unresponsive person. Call a physician.
EYE CONTACT: Immediately flush eyes thoroughly with warm water for at least 15 minutes. Hold the
eyelids open and away from the eyeballs to ensure that all surfaces are flushed thoroughly. See a
physician, preferably an ophthalmologist, immediately.
NOTES TO PHYSICIAN: Do not administer adrenaline; methylene bromide has a sensitizing effect on
the myocardium. Treatment of overexposure should be directed at the control of symptoms and the
clinical condition of the patient. Methylene bromide is metabolized to carbon monoxide and bromine and,
depending on the magnitude of exposure, high carboxyhemoglobin levels may be found.

5. Fire Fighting Measures
FLASH POINT (test method): Not applicable
AUTOIGNITION TEMPERATURE: Above 635癋 (335癈)
FLAMMABLE LIMITS IN AIR, % by volume: LOWER: Not applicable UPPER: Not applicable
EXTINGUISHING MEDIA: This solution cannot catch fire. Use media appropriate for surrounding
fire.
SPECIAL FIRE FIGHTING PROCEDURES: DANGER! Toxic, corrosive liquid and vapor.
Immediately evacuate all personnel from danger area. Toxic fumes may be given off when red gauge
glass liquid is heated to decomposition. Do not approach area without self-contained breathing apparatus
and protective clothing. Immediately spray container with water from maximum distance until cool; then
move it away from fire area if without risk. Reduce vapors with fog or fine water spray. Do not allow
runoff to drain into sewers and waterways. On-site fire brigades must comply with OSHA 29 CFR
1910.156.
UNUSUAL FIRE AND EXPLOSION HAZARDS: Heat of fire can build pressure in container,
causing rupture. Toxic, irritating vapors may spread from spill. Contact may burn skin and eyes. (See
section 4). No part of a container should be subjected to temperatures above 125癋 (51.1癈). Toxic fumes
may result from thermal decomposition. (See section 10.)
HAZARDOUS COMBUSTION PRODUCTS: Not applicable. (See section 10 for products of thermal
decomposition.)
6. Accidental Release Measures
STEPS TO BE TAKEN IF MATERIAL IS RELEASED OR SPILLED: DANGER! Toxic,
corrosive liquid and vapor. Immediately evacuate all personnel from danger area. Toxic, irritating
vapors may spread from spill. Contact may burn skin and eyes. (See section 4). Wear suitable respiratory
protection and protective clothing. (See section 8.) Reduce vapors with fog or fine water spray. Ventilate
area of spill or move leaking container to a well-ventilated area. Prevent runoff from contaminating
surrounding environment.
WASTE DISPOSAL METHOD: Prevent waste from contaminating the surrounding environment.
Keep personnel away. Discard any product, residue, disposable container, or liner in an environmentally
acceptable manner, in full compliance with federal, state, and local regulations. If necessary, call your
local supplier for assistance.
7. Handling and Storage
PRECAUTIONS TO BE TAKEN IN STORAGE: Store in a cool, dry, well-ventilated area, away
from
direct sunlight. Keep container closed when not in use and when empty. Protect containers against
physical damage. Wash thoroughly after handling.
PRECAUTIONS TO BE TAKEN IN HANDLING: Handle and use only with appropriate personal
protective equipment. (See section 8.) Keep container closed when not in use.
OTHER CONDITIONS OF STORAGE AND HANDLING: The odor of this product does not
provide adequate warning of its presence. Some means of detection other than smell should be readily
available.
