AMMONIUM FLUORIDE 17
produce symptoms resembling those of asthma. Continuing irritation of the nose may lead to perforation
of the nasal septum. External contact can cause eye irritation and conjunctivitis, irritation and ulceration
of skin wounds, and rash or external ulcers. If ingested, irritates mucous membrane and causes
vomiting; General Treatment for Exposure: INHALATION: remove to clean air and summon medical
attention. EYES: immediately flush with water for at least 15 min. and consult a physician. SKIN: flush
with water; if skin irritation develops, get medical attention. INGESTION: vomiting should occur;
follow with an emetic of soapy water; give large amounts of water; Toxicity by Inhalation (Threshold
Limit Value): 0.1 mg/m3; Short-Tenn Exposure Limits: Not pertinent; Toxicity by Ingestion: Data not
available; Late Toxicity: Data not available; Vapor (Gas) Irritant Characteristics: Not pertinent; Liquid
or Solid Irritant Characteristics: Data not available; Odor ThreshoM. Not pertinent.
Fire Hazards - Flash Point: Flammable solid; Flammable Limits in Air (96): Not pertinent; Fire
Extinguishing Agents: Water; Fire Extinguishing Agents Not To Be Used Not pertinent; Special
Hazards of Combustion Products: Greenish chromic oxide smoke may cause irritation of lungs and
mucous membranes; Behavior in Fire: Decomposes at about 180" C with spectacular swelling and
evolution of heat and nitrogen, leaving chromic oxide residue. Pressure of confined gases can burst
closed containers explosively; Ignition Temperature (deg. F) : 437; Electrical Hazard Data not

Health Hazards Information - Recommended Personal Protective Equipment: Dust mask; goggles or
face shield; rubber gloves; Symptoms Following Exposure: Inhalation of dust may cause irritation of
respiratory system. Ingestion is harmful; readily soluble fluorides may be fatal if relatively small
quantities are swallowed. Contact with eyes may causes local irritation of the mucous membrane.
Contact with skin may cause burns. High concentrations. of fluorine in the urine have been reported
following skin contact; General Treatment for Exposure: Begin first aid as quickly as possible.
INHALATION: remove to fresh air. INGESTION perform gastric lavage with limewater or 1%
calcium chloride solution; support respiration if necessary; call a physician. EYES: flush with water
for at least 15 min.; consult physician. SKIN: shower immediately with large quantities of water;
remove all contaminated clothing in the shower at once; consult physician; Toxicity by Inhalation
(Threshold Limit Value): 2.5 mg/m3 (as fluorine); Short-Tenn Exposure Limits: Data not available;
