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.
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.
