Explosion hazards: Avoid sources of ignition. Vapors may form an explosive mixture with air, especially in confined spaces. Ground and bond
containers in storage and when container is in use.
5.3 Advice to firefighters
Firefighters should wear full bunker gear including NIOSH-approved positive pressure self-contained breathing apparatus to protect against
potential hazardous combustion or decomposition products and oxygen deficiencies. Water may be used to cool closed containers to prevent
pressure buildup and possible autoignition or explosion when exposed to extreme heat. Firefighters must control runoff to prevent environmental
contamination. Notify appropriate authorities of potential fire and explosion hazard if liquid enters sewers or waterways.
6.1 Personal precautions, protective equipment and emergency procedures
Evacuate non-essential personnel. Wear appropriate protective clothing and equipment designated in Section 8.2. Ventilate the area. Remove all
sources of ignition. NO SMOKING. Clean up spills immediately. Spill creates a slip hazard.
6.2 Environmental precautions
Avoid dispersal of spilled material or runoff and prevent contact with soil and entry into drains, sewers or waterways. Use water sparingly to
minimize environmental contamination and reduce disposal requirements.
6.3 Methods and materials for containment and cleaning up
Approach spill from upwind direction. DO NOT FLUSH SPILL DOWN THE DRAIN. Cover drains and contain spill. Cover spill with a large quantity
of inert absorbent. Do not use combustible material such as sawdust. Collect material using non-sparking tools and place into an approved
container for proper disposal. Observe possible material restrictions (Sections 7.2 and 10.5). Do not allow material or runoff from rinsing
contaminated areas to enter floor drains or storm drains and ditches that lead to waterways. Dispose of via a licensed waste disposal contractor.
US regulations (CERCLA) require reporting spills and releases to soil, water and air in excess of reportable quantities.
6.4 Reference to other sections
See Section 13 for additional waste treatment information.
7.1 Precautions for safe handling
Wear all appropriate personal protective equipment specified in Section 8.2. Do not get in eyes or on skin or clothing. Do not inhale mist or vapor.
NO SMOKING. If normal use of material presents a respiratory hazard, use only adequate ventilation or wear an appropriate respirator. Open
containers slowly to control possible pressure release. Wash contaminated clothing and shoes thoroughly before reuse.
Advice on protection against fire and explosion
Keep away from heat and sources of ignition. To avoid fire or explosion, dissipate static electricity during transfer by grounding and bonding
containers and equipment before transferring material.
7.2 Conditions for safe storage, including any incompatibilities
Store in dry, cool, well-ventilated areas away from incompatible materials (see Section 10.5), food and drink. Keep away from heat and ignition
sources. Transfer only to approved containers having correct labeling. Plastics may be used for short-term storage but are not recommended for
long-term use due to deterioration effects and the subsequent risk of contamination. Keep containers tightly closed when not in use. Protect
containers against physical damage. Containers that have been opened must be carefully resealed and kept upright to prevent leakage.
Containers are hazardous when empty as they contain product residue. Do not cut, drill, weld, braze, solder grind or perform similar operations on
or near empty containers. Use appropriate containment to avoid environmental contamination. Ventilate closed areas. Keep out of reach of
children.
Outside or detached storage is recommended. Tanks must be grounded, vented and have vapor emission controls including floating roofs, inert
gas blanketing to prevent the formation of explosive mixtures and pressure vacuum relief valves to control tank pressures. Tanks should be of
welded construction and should also be diked.
7.3 Specific end uses
Apart from the uses mentioned in Section 1.2, no other specific uses are stipulated.

A "skin" notation following the inhalation exposure guideline refers to the potential for dermal absorption of the material, including eyes and mucous
membranes, either by direct contact with vapors or by direct skin contact. It is intended to alert the reader that inhalation may not be the only route
of exposure and that measures to minimize dermal exposure should be considered.
