COMPOSITION/INFORMATION ON INGREDIENTS
This product is a substance.
Description of necessary first-aid measures
Immediately flood the eye with plenty of water for at least 15 minutes, holding the eye open. Obtain
medical attention if soreness or redness persists.
Wash skin thoroughly with soap and water. Obtain medical attention if irritation persists.
Dilute by drinking large quantities of water and obtain medical attention.
Move victim to fresh air. Obtain medical attention immediately for any breathing difficulty.
Most important symptoms/effects, acute and delayed
Aside from the information found under Description of necessary first aid measures (above) and Indication
of immediate medical attention and special treatment needed, no additional symptoms and effects are
anticipated.
Indication of immediate medical attention and special treatment needed
Suitable Extinguishing Media
This preparation is used as an extinguishing agent and therefore is not a problem when trying to control a
fire. Use extinguishing agent appropriate to other materials involved.

Specific hazards arising from the chemical
Special Protective Actions for Fire-Fighters
Wear full protective clothing and self-contained breathing apparatus as appropriate for specific fire
conditions.
ACCIDENTAL RELEASE MEASURES
Personal precautions, protective equipment and emergency procedures
Wear appropriate protective clothing. Prevent skin and eye contact.
Environmental Precautions
Prevent large quantities of the material from entering drains or watercourses.
Methods and materials for containment and cleaning up
Sweep up or vacuum and transfer into suitable containers for recovery or disposal.
Precautions for safe handling
Wear appropriate protective clothing. Prevent skin and eye contact.
Conditions for safe storage
Store containers away from high heat sources. Storage area should be: - cool - dry - well ventilated under cover - out of direct sunlight
EXPOSURE CONTROLS/PERSONAL PROTECTION
Control parameters
Exposure limits are listed below, if they exist.
OSHA PEL: 50 mppcf or 15 mg/m3 TWA, total dust
15 mppcf or 5 mg/m3 TWA, respirable fraction
Appropriate engineering controls
Use with adequate ventilation. There should be local procedures for the selection, training, inspection and
maintenance of this equipment. When used in large volumes, use local exhaust ventilation.
Individual protection measures
Not normally required. Use dust mask where dustiness is prevalent, or TLV is exceeded. In oxygen
deficient atmospheres, use a self contained breathing apparatus, as an air purifying respirator will not
provide protection.
