by Ingestion: Data not available; Late Toxicity: None; Vapor (Gas) Irritm Characteristics: Non-
volatile; Liquid or Solid Irritant Characteristics: Severe skin irritant. Causes second- and third-degree
burns on short contact and is very injurious ti the EYES; Odor 27zreshold Not pertinent.
Fire Hazards - Flash Point : Oil is flammable; Flammable Limits in Air (5%): Not pertinent; Fire
Extinguishing Agents: Powdered limestone and nitrogen-propelled dry powder; Fire Extinguishing
Agenrs Not To Be Used: Water, soda ash, chemical foam, or carbon dioxide; Special Hazards of
Combustion Products: Not pertinent; Behavior in Fire: Accidental contact with water used to extinguish
surrounding fires will result in the release of hydrogen gas and possible explosion; Ignition Temperature
: No data; Electrical Hazard: Not pertinent; Burning Rate: Not pertinent.
Chemical Reactivity - Reactivity with Water: Reacts vigorously with water with the release of
flammable hydrogen gas; Reactivity with Common Materials: No reactions; Stability During Transport:
Stable at temperatures below 225 "C; Neutralizing AgentsfarAcids and Causn'cs: Neutralize only when
accidental reaction with water is complete. Do not neutralize the flammable solid with aqueous
solutions. Spent reaction solution may be neutralized with dilute solutions of acetic acid.;

Health Hazards Information - Recommended Personal Protective Equipment: Rubber protective
equipment, such as apron, boots, splash-proof goggles, gloves; canister-type respirator or self-contained
breathing apparatus; Symptom Following Exposure: Inhalation of mist causes irritation of respiratory
tract and possible systemic poisoning, hydrogen sulfide gas, which may be given off when acid is
present, causes headache, dizziness, nausea, vomiting: continued exposure can lead to loss of
consciousness, respiratory failure, and death. Liquid causes marked eye irritation, itching,
lachrymation, swelling, and corneal injury causing blurring of vision are the most common effects
exposure to light may increase the painful effects. Contact of liquid with skin causes irritation and
corrosion of tissue, continued exposure may cause dermatitis. Ingestion causes severe burning and
corrosion of all portions of the gastro-intestinal tract, pain in the throat and abdomen, MUSFXI, and
vomiting, followed by diarrhea, in severe cases, collapse, unconsciousness, and paralysis of respiration
may be expected; General Treatment for Exposure: INHALATION: move victim from contaminated
atmosphere, call physician, if breathing has ceased, start mouth-to-mouth resuscitation. EYES:
immediately flush with large quantities of running water for a minimum of 15 min., obtain medical
attention as soon as possible; while awaiting instructions from physician, patient may be kept in a dark
room and ice compresses applied to the eyes and forehead. SKIN: immediately flush affected areas with
water: obtain medical attention if irritation persists. INGESTION: obtain medical attention as soon as
possible; if patient is conscious, induce vomiting by giving large amounts of water or warm salty water
(2 tablespoons of table sail to a pint of water), if this measure is unsuccessful, vomiting may be induced
by tickling back of patient's throat with a finger. Vomiting should be encouraged until the vomitus is
clear. if patient is unconscious, do not give anything but ensure there is no obstruction to breathing (his
tongue should be kept forward and false teeth removed). He will be less likely to aspirate vomitus if
he is placed in a facedown position; Toxicity by Inhalation (Thresh0ldLim.t Value): Data not available;
Short-Term Exposure Limits: Data not available; Toxicity by Ingestion: Grade 2, LD, 0.5 to 5 gkg;
Late Toxicity: Data not available; Vapor (Gas) Zmhnt Characteristics: Vapors cause moderate irritation
