3. HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
MAY BE HARMFUL IF SWALLOWED.
IRRITATING TO SKIN, EYES AND MUCOUS MEMBRANES.
Appearance:
Colorless to white odorless crystals or powder
POTENTIAL HEALTH EFFECTS (ACUTE AND CHRONIC)
Symptoms of Exposure:
May be harmful if swallowed. Irritating to skin, mucous membranes, respiratory tract, lungs. Irritating to the
eyes; may cause eye damage with prolonged contact. Contact with open skin may cause ulceration, therefore
make sure that any cut skin is bandaged before handling material.
Medical Cond. Aggravated by Exposure:
Pre-existing skin or respiratory
disorders.
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: Get immediate medical attention; if conscious, give
water freely.
Remove contaminated clothing and wash before reuse.
5. FIRE FIGHTING MEASURES
Flash Point (F): None
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:
Thermal decomposition produces toxic fumes.
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. Store in a cool, dry, well-ventilated area. Do not breathe dust. Do not get in
eyes, on skin, or on clothing. Retained residue may make empty containers hazardous; use caution!
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 should be be handled or transferred in an approved fume hood or
with equivalent ventilation. Protective gloves should be worn to prevent skin contact (Neoprene or equivalent)
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.
