2. Hazards Identification
EMERGENCY OVERVIEW
DANGER! Toxic, corrosive liquid and vapor.
Suspect cancer hazard.
May cause liver, kidney, lung, and eye damage.
Irritates the eyes, skin, and respiratory tract.
Self-contained breathing apparatus and protective clothing
must be worn by rescue workers.
Under ambient conditions this is a liquid with a sweet,
chloroform-like odor in high concentrations.
OSHA REGULATORY STATUS: The components of this mixture are considered hazardous by
the OSHA Hazard Communications Standard (29 CFR 1910.1200).
POTENTIAL HEALTH EFFECTS:
Effects of a Single (Acute) Overexposure
Inhalation. Vapor 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, in coordination, and unconsciousness.
May also damage the liver and kidneys, and cause pulmonary edema (fluid in the lungs).
Skin Contact. May irritate the skin causing pain and a burning sensation. Harmful amounts
of material may be absorbed if skin contact is prolonged or widespread.
Swallowing. May irritate the mouth and throat, causing nausea, headache, vomiting,
abdominal pain, dizziness, tremors, stupor, and coma. May also damage the liver and
kidneys.

Product: Red Gauge Glass Liquid P- 4894-E Date: December 2009
Eye Contact. May 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.
CARCINOGENICITY: The IARC lists Sudan II (CAS 3118-97-6) as Group 3, unclassifiable as to
carcinogenicity to humans.
POTENTIAL ENVIRONMENTAL EFFECTS: None known. For further information, see section
12, Ecological Information.
3. Composition/Information on Ingredients
See section 16 for important information about mixtures.
COMPONENT CAS NUMBER CONCENTRATION
Acetylene tetrabromide 79-27-6 80%*
Methylene bromide 74-95-3 20%*
Sudan red dye 3118-97-6 0.02%*
* Percentages are approximate.
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. Immediately see a physician, preferably an ophthalmologist.
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.
Contact the Poison Control Center in your area for additional information on patient
management and follow-up.

5. Fire Fighting Measures
FLAMMABLE PROPERTIES: This solution cannot catch fire.
SUITABLE EXTINGUISHING MEDIA: Use media appropriate for surrounding fire.
PRODUCTS OF COMBUSTION: Not applicable. (See section 10 for products of thermal
decomposition.)
PROTECTION OF FIREFIGHTERS: 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.
Specific Physical and Chemical Hazards. Heat of fire can build pressure in container,
causing rupture. Toxic, irritating vapors may spread from spill. Contact may burn skin and
eyes. No part of a container should be subjected to temperatures above 125癋 (51.1癈). Toxic
fumes may result from thermal decomposition.
Protective Equipment and Precautions for Firefighters. Firefighters should wear self-
contained breathing apparatus and full fire-fighting turnout gear.
6. Accidental Release Measures
STEPS TO BE TAKEN IF MATERIAL IS RELEASED OR SPILLED:
DANGER! Toxic, corrosive liquid and vapor.
Personal Precautions. Immediately evacuate all personnel from danger area. Toxic, irritating
vapors may spread from spill. Contact may burn skin and eyes. Use self-contained breathing
apparatus and protective clothing. 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.
Environmental Precautions. 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 HANDLING: Harmful or fatal if inhaled or ingested. Do not
breathe vapor. Do not get liquid or vapor in eyes, on skin, or on clothing. Have safety showers
and eyewash fountains immediately available to exposed workers. Store and use with
adequate ventilation at all times. Keep container closed when not in use, even when empty.
Handle and use only with appropriate personal protective equipment. Keep container closed
when not in use.
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.

exposure.
Special. None.
Other. None.
PERSONAL PROTECTIVE EQUIPMENT:
Skin Protection. Wear chemically protective gloves, selected in accordance with OSHA 29
CFR 1910.132 and 1910.133. Protective clothing where needed. Select in accordance with
OSHA 29 CFR 1910.132 and 1910.133. Regardless of protective equipment, never touch live
electrical parts.
Eye/Face Protection. Safety glasses or protective goggles and full face shield. Select in
accordance with OSHA 29 CFR 1910.133.
Respiratory Protection. A respiratory protection program that meet OSHA 29 CFR 1910.134,
ANSI Z88.2, or MSHA 30 CFR 72.710 (where applicable) requirements must be followed
whenever workplace conditions warrant respirator use. Use an air-supplied or air-purifying
