aggravation of pre-existing conditions: kidney disorders.
4,First Aid Measures
Inhalation:
Remove to fresh air. Not expected to require first aid measures.
Ingestion:
Not expected to require first aid measures. Give several glasses of water to drink to dilute. If large amounts were swallowed, get medical advice.
Skin contact:
Remove any contaminated clothing. Wash skin and soap and water for at least 15 minutes. Get medical attention if irritation develops or persists.

Note to physician
In case of ingestion, monitor for acidosis and central nervous system changes. Exposed persons with previous kidney dysfunction may require special treatment.

6,Accidental Release Measures:
Ventilate area of leak or spill. Remove all sources of ignition. Wear appropriate personal protective equipment as specified in section 7. isolate hazard area. Keep unnecessary and unprotected personnel from entering.. Contain and recover liquid when possible. Use non-sparking tools and equipment. Collect liquid in an appropriate container or absorb with an inert material.(e.g., vermiculite, dry sand, earth.),and place in a chemical waste container. Do not use combustible materials, such as saw dust. Do not flush to sewer.

7, Handling And Storage
Protect container from physical damage.. Store in a cool, dry, ventilated area away from sources of heat, moisture, and incompatible substances. Containers of this material may be hazardous when empty since they retain product residues.(vapors, liquid); observe all warnings and precautions listed for the product.

8,Exposure Controls/Personal Protection
Airborne exposure limits:
Alha workplace environmental exposure level(weel): vapor and aerosol =500 ppm; aerosol, only=10 mg/m3.
Ventilation system;
A system of local and/or general exhaust is recommended to keep employee exposures below the airborne exposure limits:. 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 details.
Personal respirators (NIOSH approved):
If the exposure limit is exceeded, a half-face respirator with an organic vapor cartridge and particulate filter (NIOSH type p95 or r95 filter) may be worn for up to ten times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier. Whichever is lowest. A full-face piece respirator with an organic vapor cartridge. And particular filter(NIOSH p 100 or r100 filter) may be worn up to 50 times the exposure limit, or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. Please note that n series filters are not recommended for this material. For emergencies or instances where the exposure levels are not known, use s full-face piece 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.
