Section 7. Handling and storage
Advice on general
occupational hygiene
Conditions for safe storage,
including any
incompatibilities
Eating, drinking and smoking should be prohibited in areas where this material is
handled, stored and processed. Workers should wash hands and face before eating,
drinking and smoking. Remove contaminated clothing and protective equipment before
entering eating areas. See also Section 8 for additional information on hygiene
measures.
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. Store
locked up. 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.

Protective measures
Put on appropriate personal protective equipment (see Section 8). Avoid exposure -
obtain special instructions before use. Do not handle until all safety precautions have
been read and understood. Do not get in eyes or on skin or clothing. Do not breathe
vapor or mist. Do not swallow. Avoid release to the environment. Use only with
adequate ventilation. Wear appropriate respirator when ventilation is inadequate. Do
not enter storage areas and confined spaces unless adequately ventilated. Keep in the
original container or an approved alternative made from a 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 only non-sparking tools. Take precautionary
measures against electrostatic discharges. Empty containers retain product residue
and can be hazardous. Do not reuse container.

Precautions for safe handling
Bulk Storage Conditions: Maintain all storage tanks in accordance with applicable
regulations. Use necessary controls to monitor tank inventories. Inspect all storage
tanks on a periodic basis. Test tanks and associated piping for tightness. Maintain the
automatic leak detection devices to assure proper working condition.

Ingredient name
Exposure limits
Appropriate engineering
controls
:
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.
