SECTION 6. ACCIDENTAL RELEASE MEASURES
Personal Precautions Use personal protective equipment. Ensure adequate ventilation.
Environmental Precautions See Section 12 for additional ecological information.
Methods for Containment and Clean
Up
Avoid dust formation. Remove all sources of ignition. Use spark-proof tools and
explosion-proof equipment. Sweep up or vacuum up spillage and collect in suitable
container for disposal. Do not let this chemical enter the environment. Do not expose spill to
water.
SECTION 7. HANDLING AND STORAGE
Handling Use only in area provided with appropriate exhaust ventilation. Avoid contact with skin and
eyes. Do not breathe dust. Minimize dust generation and accumulation. Do not allow
contact with water.
Storage Keep in a dry, cool and well-ventilated place. Keep container tightly closed. Keep away
from heat and sources of ignition. Never allow product to get in contact with water during
storage. Keep under nitrogen.
SECTION 8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Exposure Guidelines This product does not contain any known or suspected reproductive hazards
Engineering Measures Ensure adequate ventilation, especially in confined areas. Ensure that eyewash stations
and safety showers are close to the workstation location.
Personal Protective Equipment
Eye/face Protection Wear appropriate protective eyeglasses or chemical safety goggles as described by
OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard
EN166.
Skin and body protection Wear appropriate protective gloves and clothing to prevent skin exposure.
Respiratory Protection Follow the OSHA respirator regulations found in 29 CFR 1910.134 or European Standard
EN 149. Use a NIOSH/MSHA or European Standard EN 149 approved respirator if
exposure limits are exceeded or if irritation or other symptoms are experienced.
Hygiene Measures Handle in accordance with good industrial hygiene and safety practice.
