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

Inhalation:
Inhalation of vapors can cause severe irritation of nose, throat, and upper respiratory tract. Inhalation of higher concentrations may cause central nervous system effects and lung damage.
Ingestion:
Causes serious burns and corrosion of the mouth, throat, and esophagus, with immediate pain and difficult swallowing. Other symptoms of abdominal pain, nausea, diarrhea and vomiting can occur, leading to shortness of breath and death. Severe poisonings may cause shock, kidney damage.
Skin Contact:
Corrosive. Symptoms of redness, pain, and severe burn can occur.
Eye Contact:
Corrosive! Vapors are irritating and may cause damage to the eyes. Contact may cause severe burns and permanent eye damage.
Chronic Exposure:
Prolonged or repeated exposure to low concentrations may cause skin irritation and burns. Prolonged or repeated exposure may cause liver and kidney damage.
Aggravation of Pre-existing Conditions:
Sensitization is rare, but may occur in persons previously sensitized to formaldehyde.

4. = = = First Aid Measures = = =

Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention immediately.
Ingestion:
If swallowed, DO NOT INDUCE VOMITING. Give large quantities of water. Never give anything by mouth to an unconscious person. Get medical attention immediately.
Skin Contact:
Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Get medical attention immediately. 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: 69C ( 156F) CC
Autoignition temperature: 601C ( 1114F)
Flammable limits in air % by volume:
lel: 18; uel: 57
Fire data listed is for formic acid. Flash Point and explosive limits are for 90% aqueous solutions of formic acid.
Explosion:
Above flash point, vapor-air mixtures are explosive within flammable limits noted above. Sensitive to static discharge.
Fire Extinguishing Media:
Dry chemical, carbon dioxide, water spray, or alcohol resistant foam.
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 = = =

Remove all sources of ignition. Ventilate area of leak or spill. 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. Neutralize with alkaline material ( soda ash, lime) , then 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! If a leak or spill has not ignited, use water spray to disperse the vapors, to protect personnel attempting to stop leak, and to flush spills away from exposures. 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.

7. = = = Handling and Storage = = =

Keep in a tightly closed container. Store in a cool, dry, ventilated area away from sources of heat or ignition. Protect against physical damage. Store separately from reactive or combustible materials, and out of direct sunlight. Strongly corrosive. Should be handled in 316 stainless steel, glass, ceramic, or similar corrosion resistant materials. 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:
-OSHA Permissible Exposure Limit ( PEL) :
5 ppm ( TWA)

-ACGIH Threshold Limit Value ( TLV) :
5 ppm ( TWA) , 10 ppm ( STEL)

-NIOSH IDLH Level: 30 ppm
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. Use explosion-proof equipment.
Personal Respirators ( NIOSH Approved) :
If the exposure limit is exceeded and engineering controls are not feasible, wear a supplied air, full-facepiece respirator, airlined hood, or full-facepiece self-contained breathing apparatus. Breathing air quality must meet the requirements of the OSHA respiratory protection standard ( 29CFR1910.134) . Formic acid has questionable warning properties and a low IDLH. Respirator recommended to 6 times the TLV value as a maximum.
Skin Protection:
Rubber or neoprene gloves and additional protection including impervious boots, apron, or coveralls, as needed in areas of unusual exposure.
Eye Protection:
Use chemical safety goggles and/ or a full face shield where splashing is possible. Maintain eye wash fountain and quick-drench facilities in work area.
