The exact chemical identity and/or exact percentage (concentration) of each ingredient may be held as confidential business information
(CBI). Any ingredient not disclosed in this section may have been determined not to be hazardous to health or the environment, or it may
be present at a level below its disclosure threshold.
4. FIRST AID MEASURES
FIRST AID FOR EYES ……………………………………………………………… SYMPTOMS: Excessive exposure may cause irritation and tearing.
RESPONSE: Flush with water for at least 15 minutes. Remove contact lenses if present and easy to do. Consult a physician if symptoms develop
and persist.
FIRST AID FOR SKIN ………………………………………………………………. SYMPTOMS: May cause skin irritation. RESPONSE: Wash with mild soap
and water. Consult a physician if effects occur and persist. No specific treatment is known or anticipated.
FIRST AID FOR INHALATION…………………………………………………… SYMPTOMS: Excessive exposure may cause slight respiratory irritation.
RESPONSE: Remove to fresh air if symptoms develop and keep comfortable for breathing. Seek medical advice if symptoms develop and persist.
FIRST AID FOR INGESTION …………………………………………………….. SYMPTOMS: No acute adverse health effects expected from amounts
ingested under normal conditions of use. RESPONSE: Seek medical attention if a significant amount is ingested.
5. FIRE FIGHTING MEASURES
EXTINGUISHING MEDIA: ………………………………………………………… SUITABLE: Foam, carbon dioxide (CO2), water, or dry chemical. Fog or
mist is recommended if water is used. NON-SUITABLE: Avoid using high pressure media.
FIRE AND EXPLOSION HAZARDS: ………………………………………….. May form combustible dust concentrations in the air. See Section 9 for
additional information. Combustion may result in the release of carbon monoxide, carbon dioxide, hydrogen chloride, nitrogen oxides,
formaldehyde, nitric acid and ammonia.
SPECIAL FIRE FIGHTING PROCEDURES: ………………………………… Wear a self-contained breathing apparatus and complete full-body personal
protective equipment. Dust may form an explosive mixture in the air, possibly resulting in a secondary explosion. Downwind personnel should be
evacuated.
6. ACCIDENTAL RELEASE MEASURES
EMERGENCY PROCEDURES : …………………………………………………. Keep unnecessary and unprotected personnel from entering area. Use
appropriate safety and personal protective equipment as indicated in Section 8.
MITIGATION AND CLEAN UP PROCEDURES: …………………………… Eliminate ignition sources. Use methods that avoid generating airborne
dust. Use a vacuum with high efficiency particulate air (HEPA) filtration is recommended. Do not create a dust cloud by brushing or sweeping, or
using compressed air.
ENVIRONMENTAL PRECAUTIONS: ………………………………………….. Contain spilled product to the extent practical and feasible.
7. HANDLING AND STORAGE
STORAGE TEMPERATURE (min./max.): …………………………………… 0 F (-17 C) / 95 F (35 C)
STORAGE: …………………………………………………………………………….. Store in cool, dry place. Keep container tightly closed in a dry, well-
ventilated place. Do not store directly in the sun or in conditions exceeding 95 F (35 C). Keep away from sources of ignition or heat. Avoid storing
near incompatible materials identified in Section 10.
HANDLING PRECAUTIONS: ……………………………………………………. Avoid dust formation. Avoid breathing dust. Wash after handling. Provide
appropriate exhaust ventilation at points of operation where dust can be generated. Avoid using compressed air. Dust may form explosive mixture
with air. Take precautionary measures against static discharges. Metal parts of mixing and processing equipment should be earthed/grounded.
Dust deposits should not be allowed to accumulate on surfaces.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
ENGINEERING CONTROLS: ……………………………………………………. Use with adequate general ventilation and/or local ventilation to keep
exposures below established limits.
EYE PROTECTION GUIDELINES: …………………………………………….. Safety glasses with side shields, or goggles if necessary.
SKIN PROTECTION GUIDELINES: ……………………………………………. Liquid-proof gloves (such as neoprene or nitrile) should be used to prevent
skin irritation. Barrier creams can be used effectively.
RESPIRATORY PROTECTION GUIDELINES: …………………………….. When ventilation cannot be made adequate enough to keep exposures
below established limits, use a NIOSH approved respirator with particulate filter, such as a N95 or greater, depending on specific workplace
conditions. Consult with your respirator and cartridge supplier to ensure proper selection of respirator and cartridge based on ingredients listed in
Section 3 and specific workplace conditions. Use and select a respirator according the guidelines established in OSHA 1910.134 or other
applicable respiratory protection standard.
