Extinguishing Media:APPLY ALCOHOL-TYPE OR ALL-PURPOSE TYPE FOAM BY
MANUFACTURER'S RECOMMENDED TECHIQUES FOR LARGE FIRES. USE CARBON
DIOXIDE OR DRY CHEMICAL MEDIA FOR SMALL FIRES.
Fire Fighting Procedures:DO NOT DIRECT A SOLID STREAM OF WATER OR FOAM
INTO BURNING MOLTEN MATERIAL; THIS MAY CAUSE SPATTERING AND SPREAD
THE FIRE. USE SELF-CONTAINED BREATHING APPARATUS, EYE PROTECTION
AND PROTECTIVE CLOTHI NG.
Unusual Fire/Explosion Hazard:DURING FIRE, OXIDES OF NITROGEN MAY BE
EVOLVED.

Spill Release Procedures:COLLECT FOR DISPOSAL. WEAR SUITABLE PROTECTIVE
EQUIPMENT. AVOID CONTACT WITH EYES AND SKIN. AVOID RUNOFF TO
WATERWAYS AND SEWERS. MONOETHANOLAMINE IS TOXIC TO AQUATIC LIFE AT
RELATIVELY LOW CONCENTRAT IONS IN WATER.

Handling and Storage Precautions:STABILITY - MONOETHANOLAMINE AND IRON
FORM A COMPLEX MOLECULE THAT CAN SPONTANEOUSLY DECOMPOSE AT
TEMPERATURES BETWEEN 130 AND 160 C, AND HAS BEEN SUSPECTED OF
CAUSING A FIRE IN A NEARLY EMPTY STORAGE TANK CONTAINING A "HEEL"
OF MEA IN CONTACT WITH CARBON STEEL COILS. WHEN THAWING, HEAT BELOW
130C.
Other Precautions:DO NOT GET IN EYES, ON SKIN OR ON CLOTHING. DO NOT
SWALLOW. AVOID BREATHING VAPORS. KEEP CONTAINER CLOSED. USE WITH
ADEQUATE VENTILATION. WASH THOROUGHLY AFTER HANDLING. FOR
INDUSTRIAL USE ONLY.

Respiratory Protection:USE SELF-CONTAINED BREATHING APPARATUS IN HIGH
VAPOR CONCENTRATIONS
Ventilation:GENERAL MECHANICAL ROOM VENTILATION IS EXPECTED TO BE
SATISFACTORY WHERE THIS PRODUCT IS STORED AND HANDLED IN CLOSED
EQUIPMENT.
Protective Gloves:PVC-COATED RUBBER
Eye Protection:MONOGOGGLES
Other Protective Equipment:EYE BATH, SAFETY SHOWER, AND CHEMICAL APRON.
SPECIAL LOCAL VENTILATION IS NEEDED AT POINTS WHERE VAPORS CAN BE
EXPECTED TO ESCAPE TO THE WORKPLACE AIR.

RECOMMENDED PROCEDURES. WASH BEFORE EATING, DRINKING OR SMOKING.
Supplemental Safety and Health
NOTE TO PHYSICIAN: THERE IS NO SPECIFIC ANTIDOTE. TREATMENT SHOULD BE
DIRECTED AT THE CONTROL OF SYMPTOMS AND CLINICAL CONDITION OF THE
PATIENT. THE HAZARDS OF THIS MATERIAL ARE DUE MAINLY TO ITS SEVE
RELY IRRITANT POPERTIES ON SKIN AND MUCOSAL SURFACES. THE STOMACH
SHOULD BE EVACUATED CAREFULLY IN CASE OF POISONING.
