Special Information:
Use protective clothing and breathing equipment appropriate for the surrounding fire.
6. Accidental Release Measures
Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8.
Contain and recover liquid when possible. Collect liquid in an appropriate container or absorb with an inert
material (e. g., vermiculite, dry sand, earth), and place in a chemical waste container. Do not use combustible
materials, such as saw dust. US Regulations (CERCLA) require reporting spills and releases to soil, water and
air in excess of reportable quantities. The toll free number for the US Coast Guard National Response Center is
(800) 424-8802.
7. Handling and Storage
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage.
Containers of this material may be hazardous when empty since they retain product residues (vapors, liquid);
observe all warnings and precautions listed for the product.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
None established.
Ventilation System:
In general, dilution ventilation is a satisfactory health hazard control for this substance. However, if conditions
of use create discomfort to the worker, a local exhaust system should be considered.
Personal Respirators (NIOSH Approved):
Not expected to require personal respirator usage.
Skin Protection:
Wear protective gloves and clean body-covering clothing.
Eye Protection:
Use chemical safety goggles and/or a full face shield where splashing is possible. Maintain eye wash fountain
and quick-drench facilities in work area.
