Potential Health Effects
----------------------------------

Inhalation:
May be destructive to the mucous membranes and upper respiratory tract. Symptoms may include burning, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting. May be fatal as a result of spasm, inflammation and edema of the larynx and bronchi, chemical pneumonitis and pulmonary edema.

Ingestion:
Highly toxic! May cause pain and burning in the mouth, pharynx, and stomach, vomiting diarrhea, and fall in blood pressure. Asphyxia may occur from edema of the glottis. May be destructive to the gastro-intestinal tract. Estimated lethal dose 5 milliliters.

Skin Contact:
Toxic! Corrosive! May cause irritation, inflammation, burns, and skin rashes. Absorption through the skin may cause systemic poisoning, nausea, and vomiting.

Eye Contact:
Corrosive! Vapors may cause irritation. Splashes from dilute solutions may cause burns and serious eye damage.

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:
DO NOT INDUCE VOMITING. Give large quantities of water. Never give anything by mouth to an unconscious person. Call a physician immediately.

Skin Contact:
Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Get medical attention. Wash clothing before reuse. Thoroughly clean shoes before reuse.

Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids occasionally. Get medical attention immediately.


5. Fire Fighting Measures

Fire:
Flash point: 51C (124F) Autoignition temperature: 438C (820F) Flammable limits in air % by volume: lel: 2; uel: 8 Flammable.

Explosion:
Above flash point, vapor-air mixtures are explosive within flammable limits noted above. Vapors can flow along surfaces to distant ignition source and flash back. An explosion may occur upon polymerization.

Fire Extinguishing Media:
Dry chemical, foam, water or carbon dioxide. Water spray may be used to keep fire exposed containers cool.

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. Remove all sources of ignition. Wear appropriate personal protective equipment as specified in Section 8. 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! US Regulations (CERCLA) require reporting spills and releases to soil, water and air in excess of reportable quantities. The toll free number for the US Coast Guard National Response Center is (800) 424-8802. J. T. Baker NEUTRASORB(tm) or TEAM(tm) 'Low Na+' acid neutralizers are recommended for spills of this product.


7. Handling and Storage

Protect against physical damage. Detached storage is preferred. Store in a cool, dry, well-ventilated, non-combustible area. The acid may be stored safely for extended periods if kept below its melting point 13C (54F). Separate from oxidizing materials. Do not store in inert atmosphere. If acrylic acid has been stored below its melting point, first allow the whole batch to melt and stir before discharging. Acrylic acid vapor contains no inhibitor; the condensate may therefore polymerize inside exhaust or ventilation equipment, with the risk of disturbances. Do not use any heating systems to thaw solidified monomer. Use only in a chemical fume hood. 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:
-ACGIH Threshold Limit Value (TLV): 2 ppm (TWA) (skin)

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 full facepiece respirator with organic vapor cartridge 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. For emergencies or instances where the exposure levels are not known, use a full-facepiece positive-pressure, air-supplied respirator. WARNING: Air purifying respirators do not protect workers in oxygen-deficient atmospheres.

Skin Protection:
Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as appropriate, to prevent skin contact.

Eye Protection:
Use chemical safety goggles and/or a full face shield where splashing is possible.
