|3. HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
MAY BE FATAL IF INHALED, SWALLOWED OR ABSORBED THROUGH SKIN.
IRRITATING TO SKIN, EYES AND MUCOUS MEMBRANES.
MAY CAUSE BURNS.
May Cause Damage To Central Nervous System, Kidneys, and Respiratory
System.
WARNING: This product contains a chemical(s) known to the State of
California to cause birth defects or other reproductive
harm.
Appearance:
Red-orange, relatively odorless, crystalline powder
POTENTIAL HEALTH EFFECTS (ACUTE AND CHRONIC)
Symptoms of Exposure:
POISON! May be fatal if inhaled, swallowed or absorbed thru skin. Danger of cumulative effects. Causes irritation, possible
burns, on contact with skin or eyes. Affects central nervous system, kidneys. Causes nausea, drowsiness, headache,
respiratory failure. Aggravates pre-existing respiratory and kidney conditions.
Medical Cond. Aggravated by Exposure:
Respiratory and kidney conditions
Routes of Entry:
Inhalation, ingestion or skin contact.
Carcinogenicity:
The material is not listed (IARC, NTP, OSHA) as cancer causing
agent.
4. FIRST AID MEASURES
Emergency First Aid:
GET MEDICAL ASSISTANCE FOR ALL CASES OF OVEREXPOSURE.
Skin: Immediately flush thoroughly with large amounts of water.
Eyes: Immediately flush thoroughly with water for at least 15
minutes.
Inhalation: Remove to fresh air; give artificial respiration if
breathing has stopped.
Ingestion: If conscious, drink water and induce vomiting
immediately as directed by medical personnel. Never give anything
by mouth to an unconscious person.
Remove contaminated clothing and wash before reuse.
5. FIRE FIGHTING MEASURES
Flash Point (F): Noncombustible
Flammable Limits LEL (%): N/A
Flammable Limits UEL (%): N/A
Extinguishing Media:
Use any suitable for adjacent material.
Fire Fighting Procedures:
Wear self-contained breathing apparatus and protective clothing.
Fire & Explosion Hazards:
Can ignite combustible matter by oxidation. Thermal decomposition produces toxic fumes. Explosive reaction with acetyl
nitrate, butadiene + ethanol + iodine (at 35C), chlorine + hydrocarbons, diboron tetrafluoride, hydrogen peroxide + traces of
nitric acid, reducing agents.
6. ACCIDENTAL RELEASE MEASURES
Spill Response:
Evacuate the area of all unnecessary personnel. Wear suitable protective equipment listed under Exposure / Personal
Protection. Eliminate any ignition sources until the area is determined to be free from explosion or fire hazards. Contain the
release and eliminate its source, if this can be done without risk. Take up and containerize for proper disposal as described
under Disposal. Comply with Federal, State, and local regulations on reporting releases. Refer to Regulatory Information for
reportable quantity and other regulatory data.
7. HANDLING AND STORAGE
Handling & Storage:
Keep container tightly closed and protected from light. Store in a cool, well-ventilated area. Do not breathe dust. Do not get
in eyes, on skin, or on clothing.
8. EXPOSURE CONTROLS / PERSONAL PROTECTION
ENGINEERING CONTROLS AND PERSONAL PROTECTIVE EQUIPMENT:
Ventilation, Respiratory Protection, Protective Clothing, Eye Protection:
Respiratory Protection: If workplace exposure limit(s) of product or any component is exceeded (see TLV/PEL), a
NIOSH/MSHA approved air supplied respirator is advised in absence of proper environmental control. OSHA regulations
also permit other NIOSH/MSHA respirators (negative pressure type) under specified conditions (see your safety equipment
supplier). Engineering and/or administrative controls should be implemented to reduce exposure. Material must be handled or
transferred in an approved fume hood or with equivalent ventilation. Protective gloves (Neoprene, PVC or equivalent) should
be worn to prevent skin contact. Safety glasses with side shields must be worn at all times. Impervious protective clothing
should be worn to prevent skin contact.
Work/Hygenic Practices:
Wash thoroughly after handling. Do not take internally. Eye wash and safety equipment should be readily available.
