3. Hazards Identification

Emergency Overview

WARNING! May be harmful if swallow. Cause irritation to skin, eyes and

respiratory tract.

Potential Health Effects

Information on the human health effects from exposure to this substance is


Inhalation: No information found, but compound should be handled as a

potential health hazard.

Ingestion: No information found, but compound should be handled as a

potential health hazard.

Skin Contact: Causes irritation.

Eye Contact: Causes irritation.

Chronic Exposure: No information found.

Aggravation of Pre-existing Conditions: No information found.


4. First Aid Measures

Inhalation: Remove to fresh air. If not breathing, give artificial respiration. If

breathing is difficult, give oxygen. Call a physician.

Ingestion: Induce vomiting immediately as directed by medical personnel.

Never give anything by mouth to an unconscious person. Get medical


Skin Contact: Remove any contaminated clothing. Wash skin with soap or

mild detergent and water for at least 15 minutes. Get medical attention if

irritation develops or persists. Wash clothing before re-use.

Eye Contact: Immediately flush eyes with plenty of water for at least 15

minutes, lifting lower and upper eyelids occasionally. Get medical attention



5. Fire-Fighting Measures

Fire: Not considered to be a fire hazard.

Explosion: Not considered to be an explosion hazard.

Fire Extinguishing Media: Use any means suitable for extinguishing

surrounding fire.

Special Information: In the event of a fire, wear full protective clothing and

NIOSH-approved self-contained breathing apparatus with full facepiece

operated in the pressure demand or other positive pressure mode.


6. Accidental Release Measures

Ventilate area of leak or spill. Wear appropriate personal protective

equipment as specified in Section 8. Spills: Sweep up and containerize for

reclamation or disposal. Vacuuming or wet sweeping may be used to avoid

dust dispersal. Ventilate area of leak or spill. Wear appropriate personal

protective equipment as specified in Section 8. Spills: Pick up and place in a

suitable container for reclamation or disposal, using a method that does not

generate dust.


7. Handling And Storage

Keep in a tightly closed container, stored in a cool, dry, ventilated area.

Protect against physical damage. Isolate from incompatible substances.

Containers of this material may be hazardous when empty since they retain

product residues (dust, solids); observe all warnings and precautions listed

for the product.


8. Exposure Controls / Personal Protection

Airborne Exposure Limits:

None established.

Ventilation System: A system of local and/or general exhaust is

recommended to keep employee exposures as low as possible. Local

exhaust ventilation is generally preferred because it can control the

emissions of the contaminant at its source, preventing dispersion of it into the

general work area. Please refer to the ACGIH document, Industrial

Ventilation, A Manual of Recommended Practices, most recent edition, for


Personal Respirators: For conditions of use where exposure to the dust or

mist is apparent, a half-face dust/mist respirator may be worn. For

emergencies or instances where the exposure levels are not known, use a

full-face positive-pressure, air-supplied respirator.

WARNING: Air-purifying respirators do not protect workers in

oxygen-deficient atmospheres.

Skin Protection: Wear protective gloves and clean body-covering clothing.

Eye Protection: Use chemical safety goggles. Maintain eye wash fountain

and quick-drench facilities in work area.
