Hazards and Protection.
Storage
Do not handle in areas where risk of inhalation andor food contamination may be possible. Adequate ventilation. Wear rubber gloves, full protective shield, and all-purpose canister mask. Avoid contact with alkaline metals.
Handling
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Protection
Wear appropriate protective gloves, clothing and goggles.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers.
Stability
No data.
Incompatibilities
Reacts in this way with all bases, both organic (for example, the amines) and inorganic Can react with active metals to form gaseous hydrogen and a metal salt Flammable and/or toxic gases and heat are generated by the reaction with with diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides.
Decomposition
When heated to decomposition, it emits highly toxic fumes of hydrogen fluoride.

Fire.
Flash Point,°C
55
Fire fighting
Stay upwind; keep out of low areas. Wear self-contained, positive pressure breathing apparatus and full protective clothing. Move container from fire area. Cool containers that are exposed to flames with water from the side until well after fire is out.Small fires: use dry chemical, carbon dioxide, water spray, or foam. For large fires, use water spray, fog, or foam.
Fire potential
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.
Hazards
When heated to decomposition, it emits highly toxic fumes of fluorine containing compounds. Some of these materials may burn but none ignite readily. These materials may ignite combustibles (wood, paper, oil, etc.).
Combustion products
Fire may produce irritating, corrosive and/or toxic gases.

Health.
Exposure limit(s)
TLV: ppm; 0.05 mg/m3 for sodium fluoracetate (skin) (ACGIH 1994-1995).
Poison_Class
1
Exposure effects
Respiratory depression, reduced body temperature, rapid heart rate, and abnormally low blood pressure may occur. Apprehension, diaphoresis, disorientation, agitation, paresthesias, muscle twitching, hyperactive behavior, tingling, coma, and convulsions may develop.
   Ingestion
Nausea, vomiting, hypersalivation, abdominal or epigastric pain, and diarrhea may be seen.
   Inhalation
Respiratory depression and cyanosis may develop. Death may be due to hypoxia and respiratory depression during seizures.
   Skin
Contact with molten substance may cause severe burns to skin and eyes. See Inhalation.
   Eyes
Blurred vision, facial paresthesias, and hypersalivation may be noted.

First aid
 
   Ingestion
Do not induce emesis. Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents.
   Inhalation
Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols.
   Skin
Remove and isolate contaminated clothing and shoes. Immediately flush with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin.
   Eyes
Immediately flush with running water for at least 20 minutes.
