EMERGENCY OVERVIEW

MAY CAUSE MODERATE IRRITATION TO THE SKIN. POTENTIAL SKIN SENSITIZER. CORROSIVE TO THE EYES. MISTS/AEROSOLS CAUSE IRRITATION TO THE UPPER RESPIRATORY TRACT.

ODOR: SLIGHT

APPEARANCE: YELLOW TO AMBER, LIQUID

FIRE FIGHTERS SHOULD WEAR POSITIVE PRESSURE SELF-CONTAINED BREATHING APPARATUS (FULL FACE-PIECE TYPE).

PROPER FIRE-EXTINGUISHING MEDIA: FLOOD WITH WATER. USE OF CO2 OR FOAM MAY NOT BE EFFECTIVE.

POTENTIAL HEALTH EFFECTS

ACUTE SKIN EFFECTS: PRIMARY ROUTE OF EXPOSURE; MAY CAUSE MODERATE IRRITATION TO THE SKIN. POTENTIAL SKIN SENSITIZER.

ACUTE EYE EFFECTS: CORROSIVE TO THE EYES.

ACUTE RESPIRATORY EFFECTS: MISTS/AEROSOLS CAUSE IRRITATION TO THE UPPER RESPIRATORY TRACT.

INGESTION EFFECTS: MAY CAUSE GASTROINTESTINAL IRRITATION. VERY LARGE DOSES MAY CAUSE DIARRHEA, DEPRESSION, COLIC AND DEATH. MAY ALSO CAUSE SEVERE ALLERGIC REACTIONS IN SENSITIVE INDIVIDUALS.

TARGET ORGANS: REPEATED SKIN CONTACT MAY CAUSE SENSITIZATION.

MEDICAL CONDITIONS AGGRAVATED: NOT KNOWN.

SYMPTOMS OF EXPOSURE: CAUSES REDNESS OR ITCHING OF SKIN, POSSIBLY LEADING TO BURNS (DEPENDENT ON THE LENGTH OF EXPOSURE).

------4) FIRST AID MEASURES ------

SKIN CONTACT: WASH THOROUGHLY WITH SOAP AND WATER.  REMOVE CONTAMINATED CLOTHING.  THOROUGHLY WASH CLOTHING BEFORE REUSE.  GET MEDICAL ATTENTION IF IRRITATION DEVELOPS OR PERSISTS.

EYE CONTACT: URGENT!  IMMEDIATELY FLUSH EYES WITH PLENTY OF LOW-PRESSURE WATER FOR AT LEAST 20 MINUTES WHILE REMOVING CONTACT LENSES.  HOLD EYELIDS APART.  GET IMMEDIATE MEDICAL ATTENTION.

INHALATION: REMOVE TO FRESH AIR.  IF BREATHING IS DIFFICULT, GIVE OXYGEN.  IF BREATHING HAS STOPPED, GIVE ARTIFICIAL RESPIRATION.  GET IMMEDIATE MEDICAL ATTENTION.

INGESTION: DO NOT FEED ANYTHING BY MOUTH TO AN UNCONSCIOUS OR CONVULSIVE VICTIM. DO NOT INDUCE VOMITING. IMMEDIATELY CONTACT PHYSICIAN.  DILUTE CONTENTS OF STOMACH USING 3-4 GLASSES MILK OR WATER.

NOTES TO PHYSICIANS: NO SPECIAL INSTRUCTIONS

------5) FIRE FIGHTING MEASURES ------

FIRE FIGHTING INSTRUCTIONS: FIRE FIGHTERS SHOULD WEAR POSITIVE PRESSURE SELF-CONTAINED BREATHING APPARATUS (FULL FACE-PIECE TYPE).

EXTINGUISHING MEDIA: FLOOD WITH WATER. USE OF CO2 OR FOAM MAY NOT BE EFFECTIVE.

HAZARDOUS DECOMPOSITION PRODUCTS: THERMAL DECOMPOSITION (DESTRUCTIVE FIRES) YIELDS ELEMENTAL OXIDES.

FLASH POINT: > 200F > 93C SETA(CC)

------6) ACCIDENTAL RELEASE MEASURES ------

PROTECTION AND SPILL CONTAINMENT: VENTILATE AREA. USE SPECIFIED PROTECTIVE EQUIPMENT. ABSORB ON PAPER TRIM RECYCLE PAPER TRIM INTO HYDROPULPER. IF OTHER ABSORBENT MATERIAL IS USED IT SHOULD BE CONSIDERED A PESTICIDE, PLACED IN A WASTE DISPOSAL CONTAINER AND DISPOSED OF IN AN APPROVED PESTICIDE LANDFILL. SEE PRODUCT LABEL FOR STORAGE AND DISPOSAL INSTRUCTIONS.

FLUSH AREA WITH WATER. SPREAD SAND/GRIT. NEUTRALIZE WITH SODA ASH.

DISPOSAL INSTRUCTIONS: THE WASTE CHARACTERISTICS OF THE ABSORBED MATERIAL, OR ANY CONTAMINATE SOIL, SHOULD BE DETERMINED IN ACCORDANCE WITH PROVINCIAL REGULATIONS. WATER CONTAMINATED WITH THIS PRODUCT MAY BE SENT TO A SANITARY SEWER TREATMENT FACILITY, IN ACCORDANCE WITH ANY LOCAL AGREEMENT OR DISCHARGED UNDER PROVINCIAL REGULATIONS.

DISPOSE OF IN APPROVED PESTICIDE FACILITY OR ACCORDING TO LABEL INSTRUCTIONS.

------7) HANDLING AND STORAGE ------

HANDLING: ACIDIC. CORROSIVE (EYES). DO NOT MIX WITH ALKALINE MATERIAL.

STORAGE: KEEP CONTAINERS CLOSED WHEN NOT IN USE. AVOID EXCESSIVE HEAT AND CONTAMINATION. STORE ONLY IN VENTED CONTAINERS.
