Hazards and Protection.
Storage
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
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
Chemical splash goggles in compliance with OSHA regulations are advised; however, OSHA regulations also permit other type safety glasses. Whre chemical resistant gloves. To prevent repeated or prolonged skin contact, wear impervious clothing and boots.
Respirators
Use NIOSH/MSHA approved respirator appropriate for exposure of concern.
Small spills/leaks
Avoid inhalation and skin contact.
Stability
No data.
Incompatibilities
Strong oxidizing agents.

Fire.
Flash Point,°C
145
Fire fighting
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 agent most appropriate to extinguish fire.
Hazards
When heated to decomposition, it emits very toxic fumes of fluorides and nitrogen oxides. Avoid decomposing heat.

Health.
Exposure effects
Should systemic fluoride poisoning occur following absorption of cyanuric fluoride, blood calcium could decrease causing an increase in skeletal muscle excitability, hyperactive reflexes, painful spasms (particularly in the extremities), weakness and tetanic contractures 3 to 5 hours later. CYANURIC FLUORIDE - <br>&nbsp;&nbsp;&nbsp;1. No data were available to assess the possible of cyanuric fluoride. <br>CYANURIC CHLORIDE - <br>&nbsp;&nbsp;&nbsp;1. The similar compound, cyanuric chloride, was not teratogenic in chick embryos. <br>No information about possible male reproductive effects was found in available references.
   Ingestion
The similar compound, cyanuric chloride, caused corrosive damage to the gastrointestinal tract when fed at high doses to experimental animals.
   Inhalation
Respiratory tract irritation was seen in both human volunteers and experimental animals exposed to fumes of the similar compound, cyanuric chloride. Inhalation of cyanuric chloride dust by rats at a concentration of 1.88 Mg/m(3) 4 hours daily for 2 and 1/2 months caused respiratory tract irritation with a fatality rate of 30 percent.
   Skin
Cyanuric fluoride readily penetrates all layers of the skin in rabbits. The similar compound, cyanuric chloride, causes skin irritation on direct contact.

First aid
 
   Ingestion
The possible benefit of early removal of some ingested material by cautious gastric lavage must be weighed against potential complications of bleeding or perforation. Activated charcoal activated charcoal binds most toxic agents and can decrease their systemic absorption if administered soon after ingestion. 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 contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists. Treat dermal irritation or burns with standard topical therapy. Patients developing dermal hypersensitivity reactions may require treatment with systemic or topical corticosteroids or antihistamines.
   Eyes
To prevent reaction with water and possible release of more irritating fluoride, first dry-wipe away any loose material from the eyes. Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility. Severe eye irritation and corneal ulceration may occur with direct eye contact. Prolonged initial flushing and early ophthalmologic consultation are advisable.
