7. Handling and storage
Store in accordance with local regulations. Store in a segregated and approved area.
Store in original container protected from direct sunlight in a dry, cool and well-ventilated
area, away from incompatible materials (see Section 10) and food and drink. Eliminate
all ignition sources. Separate from oxidizing materials. Keep container tightly closed
and sealed until ready for use. Containers that have been opened must be carefully
resealed and kept upright to prevent leakage. Do not store in unlabeled containers.
Use appropriate containment to avoid environmental contamination.
compatible material, kept tightly closed when not in use. Store and use away from heat,
sparks, open flame or any other ignition source. Use explosion-proof electrical
(ventilating, lighting and material handling) equipment. Use non-sparking tools. Take
precautionary measures against electrostatic discharges. To avoid fire or explosion,
dissipate static electricity during transfer by grounding and bonding containers and
equipment before transferring material. Empty containers retain product residue and
can be hazardous. Do not reuse container.

8. Exposure controls/personal protection
Use a properly fitted, air-purifying or air-fed respirator complying with an approved
standard if a risk assessment indicates this is necessary. Respirator selection must be
based on known or anticipated exposure levels, the hazards of the product and the safe
working limits of the selected respirator.
Personal protection
Respiratory :
Engineering measures : Use only with adequate ventilation. Use process enclosures, local exhaust ventilation or
other engineering controls to keep worker exposure to airborne contaminants below any
recommended or statutory limits. The engineering controls also need to keep gas,
vapor or dust concentrations below any lower explosive limits. Use explosion-proof
ventilation equipment.
Hygiene measures : Wash hands, forearms and face thoroughly after handling chemical products, before
eating, smoking and using the lavatory and at the end of the working period.
Appropriate techniques should be used to remove potentially contaminated clothing.
Wash contaminated clothing before reusing. Ensure that eyewash stations and safety
showers are close to the workstation location.
Recommended monitoring
procedures : If this product contains ingredients with exposure limits, personal, workplace
atmosphere or biological monitoring may be required to determine the effectiveness of
the ventilation or other control measures and/or the necessity to use respiratory
protective equipment. Reference should be made to appropriate monitoring standards.
Reference to national guidance documents for methods for the determination of
hazardous substances will also be required.
