**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Causes severe burns.
Potential Health Effects
Eye:
Contact with liquid is corrosive to the eyes and causes severe
burns. Lachrymator (substance which increases the flow of tears).
May cause corneal edema, ulceration, and scarring.
Skin:
Causes skin burns. The severity of injury depends on the
concentration of the solution and the duration of exposure.
Ingestion:
Causes severe digestive tract burns with abdominal pain, vomiting,
and possible death.
Inhalation:
Causes chemical burns to the respiratory tract.
Chronic:
Chronic absorption of formic acid may cause damage to the kidneys,
which is indicated by albuminuria and hematuria. Chronic skin contact
may cause sensitization dermatitis, particularly in workers
previously sensitized to formaldehyde.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
In case of contact, immediately flush eyes with plenty of water for
at least 15 minutes. Get medical aid immediately.
Skin:
In case of contact, immediately flush skin with plenty of water for
at least 15 minutes while removing contaminated clothing and shoes.
Get medical aid immediately. Wash clothing before reuse.
Ingestion:
If swallowed, do NOT induce vomiting. Get medical aid immediately.
If victim is fully conscious, give a cupful of water. Never give
anything by mouth to an unconscious person.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Hemodialysis should be considered in severe intoxication. Persons
with chronic respiratory, skin, kidney, or liver diseases or eye
disorders may be at increased risk from exposure to this product.
Antidote:
Folic acid may be of benefit by hastening the metabolism of formic
acid to carbon dioxide.
**** SECTION 5 - FIRE FIGHTING MEASURES ****
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Use water
spray to keep fire-exposed containers cool. Containers may explode in
the heat of a fire. Contact with metals may evolve flammable hydrogen
gas. Vapors are heavier than air and may travel to a source of
ignition and flash back. Vapors can spread along the ground and
collect in low or confined areas.
Extinguishing Media:
Use water fog, dry chemical, carbon dioxide, or regular foam.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Large spills may be neutralized
with dilute alkaline solutions of soda ash (sodium carbonate,
Na2CO3), or lime (calcium oxide, CaO). Remove all sources of
ignition. Use a spark-proof tool. Provide ventilation. Approach spill
from upwind.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Contents may develop pressure upon prolonged
storage. Do not get in eyes, on skin, or on clothing. Empty
containers retain product residue, (liquid and/or vapor), and can be
dangerous. Discard contaminated shoes. Do not pressurize, cut, weld,
braze, solder, drill, grind, or expose empty containers to heat,
sparks or open flames. Use only with adequate ventilation. Keep away
from heat and flame. Do not breathe vapor or mist.
Storage:
Keep refrigerated. (Store below 4C/39F.) Keep from contact with
oxidizing materials. Corrosives area. Do not store in metal
containers. Do not store near alkaline substances. Vent
periodically. Glacial formic acid will slowly decompose to carbon
monoxide at room temperature resulting in increased pressure if
containers are sealed or unvented.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use explosion-proof ventilation equipment. Facilities storing or
utilizing this material should be equipped with an eyewash facility
and a safety shower. Use adequate general or local exhaust
ventilation to keep airborne concentrations below the permissible
exposure limits.

dissolve in cloud water where it reacts with dissolved hydroxyl
radicals. It also reacts in the vapor phase with hydroxyl radicals
(half-life 36 days).
