SUMMARY
- FIRST AID - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 116 (ERG, 2004)
Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with liquefied gas, thaw frosted parts with lukewarm water. In case of burns, immediately cool affected skin for as long as possible with cold water. Do not remove clothing if adhering to skin. Keep victim warm and quiet. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves.
FIRST AID EYE EXPOSURE - If the eye tissue is frozen, seek medical attention immediately; if tissue is not frozen, immediately and thoroughly flush the eyes with large amounts of water for at least 15 minutes, occasionally lifting the lower and upper eyelids. If irritation, pain, swelling, lacrimation, or photophobia persist, get medical attention as soon as possible. DERMAL EXPOSURE - If frostbite has occurred, seek medical attention immediately; do not rub the affected areas or flush them with water. In order to prevent further tissue damage, do not attempt to remove frozen clothing from frostbitten areas. If frostbite has not occurred, immediately and thoroughly wash contaminated skin with soap and water. INHALATION EXPOSURE - Move the exposed person to fresh air at once. If breathing has stopped, perform artificial respiration. Keep the affected person warm and at rest. Get medical attention as soon as possible. TARGET ORGANS - Central nervous system (National Institute for Occupational Safety and Health, 2007).
INHALATION EXPOSURE - 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 an inhaled beta2-adrenergic agonist. Consider systemic corticosteroids in patients with significant bronchospasm. If bronchospasm and wheezing occur, consider treatment with inhaled sympathomimetic agents.
DERMAL EXPOSURE - DECONTAMINATION: Remove contaminated clothing and jewelry and place them in plastic bags. Wash exposed areas with soap and water for 10 to 15 minutes with gentle sponging to avoid skin breakdown. A physician may need to examine the area if irritation or pain persists (Burgess et al, 1999). If frostbite has occurred, do not rub the affected areas or flush them with water or attempt to remove frozen clothing. PREHOSPITAL Rewarming of a localized area should only be considered if the risk of refreezing is unlikely. Avoid rubbing the frozen area which may cause further damage to the area (Grieve et al, 2011; Hallam et al, 2010).
REWARMING Do not institute rewarming unless complete rewarming can be assured; refreezing thawed tissue increases tissue damage. Place affected area in a water bath with a temperature of 40 to 42 degrees Celsius for 15 to 30 minutes until thawing is complete. The bath should be large enough to permit complete immersion of the injured part, avoiding contact with the sides of the bath. A whirlpool bath would be ideal. Some authors suggest a mild antibacterial (ie, chlorhexidine, hexachlorophene or povidone-iodine) be added to the bath water. Tissues should be thoroughly rewarmed and pliable; the skin will appear a red-purple color (Grieve et al, 2011; Hallam et al, 2010; Murphy et al, 2000). Correct systemic hypothermia which can cause cold diuresis due to suppression of antidiuretic hormone; consider IV fluids (Grieve et al, 2011). Rewarming may be associated with increasing acute pain, requiring narcotic analgesics. For severe frostbite, clinical trials have shown that pentoxifylline, a phosphodiesterase inhibitor, can enhance tissue viability by increasing blood flow and reducing platelet activity (Hallam et al, 2010).
WOUND CARE Digits should be separated by sterile absorbent cotton; no constrictive dressings should be used. Protective dressings should be changed twice per day. Perform twice daily hydrotherapy for 30 to 45 minutes in warm water at 40 degrees Celsius. This helps debride devitalized tissue and maintain range of motion. Keep the area warm and dry between treatments (Hallam et al, 2010; Murphy et al, 2000). The injured extremities should be elevated and should not be allowed to bear weight. In patients at risk for infection of necrotic tissue, prophylactic antibiotics and tetanus toxoid have been recommended by some authors (Hallam et al, 2010; Murphy et al, 2000). Non-tense clear blisters should be left intact due to the risk of infection; tense or hemorrhagic blisters may be carefully aspirated in a setting where aseptic technique is provided (Hallam et al, 2010). Further surgical debridement should be delayed until mummification demarcation has occurred (60 to 90 days). Spontaneous amputation may occur. Analgesics may be required during the rewarming phase; however, patients with severe pain should be evaluated for vasospasm. IMAGING: Arteriography and noninvasive vascular techniques (e.g., plain radiography, laser Doppler studies, digital plethysmography, infrared thermography, isotope scanning), have been useful in evaluating the extent of vasospasm after thawing and assessing whether debridement is needed (Hallam et al, 2010). In cases of severe frostbite, Technetium 99 (triple phase scanning) and MRI angiography have been shown to be the most useful to assess injury and determine the extent or need for surgical debridement (Hallam et al, 2010). TOPICAL THERAPY: Topical aloe vera may decrease tissue destruction and should be applied every 6 hours (Murphy et al, 2000). IBUPROFEN THERAPY: Ibuprofen, a thromboxane inhibitor, may help limit inflammatory damage and reduce tissue loss (Grieve et al, 2011; Murphy et al, 2000). DOSE: 400 mg orally every 12 hours is recommended (Hallam et al, 2010). THROMBOLYTIC THERAPY: Thrombolysis (intra-arterial or intravenous thrombolytic agents) may be beneficial in those patients at risk to lose a digit or a limb, if done within the first 24 hours of exposure. The use of tissue plasminogen activator (t-PA) to clear microvascular thromboses can restore arterial blood flow, but should be accompanied by close monitoring including angiography or technetium scanning to evaluate the injury and to evaluate the effects of t-PA administration. Potential risk of the procedure includes significant tissue edema that can lead to a rise in interstitial pressures resulting in compartment syndrome (Grieve et al, 2011). CONTROVERSIAL: Adjunct pharmacological agents (ie, heparin, vasodilators, prostacyclins, prostaglandin synthetase inhibitors, dextran) are controversial and not routinely recommended. The role of hyperbaric oxygen therapy, sympathectomy remains unclear (Grieve et al, 2011). CHRONIC PAIN: Vasomotor dysfunction can produce chronic pain. Amitriptyline has been used in some patients; some patients may need a referral for pain management. Inability to tolerate the cold (in the affected area) has been observed following a single episode of frostbite (Hallam et al, 2010). MORBIDITIES: Frostbite can produce localized osteoporosis and possible bone loss following a severe case. These events may take a year or more to develop. Children may be at greater risk to develop more severe events (ie, early arthritis) (Hallam et al, 2010).
EYE EXPOSURE - DECONTAMINATION: Remove contact lenses and irrigate exposed eyes with copious amounts of room temperature 0.9% saline or water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist after 15 minutes of irrigation, the patient should be seen in a healthcare facility. If contact with escaping gas may have caused frostbite of the eye, DO NOT flush with water; early ophthalmologic consultation should be obtained.

-PHYSICAL HAZARDS
FIRE HAZARD
POTENTIAL FIRE OR EXPLOSION HAZARDS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 116 (ERG, 2004) EXTREMELY FLAMMABLE. Will be easily ignited by heat, sparks or flames. Will form explosive mixtures with air. Silane will ignite spontaneously in air. Those substances designated with a "P" may polymerize explosively when heated or involved in a fire. Vapors from liquefied gas are initially heavier than air and spread along ground. Vapors may travel to source of ignition and flash back. Cylinders exposed to fire may vent and release flammable gas through pressure relief devices. Containers may explode when heated. Ruptured cylinders may rocket.
Vinyl fluoride is a flammable gas; it is considered a very dangerous fire hazard (Lewis, 1994; NIOSH , 1996). It can be easily ignited. The vapors are heavier than air, hence, it can easily flashback to the source of a leak (liquid or vapor) (AAR, 1994; ((CHRIS, 1996)). This compound will float on water; while floating it will boil forming a visible, flammable vapor cloud ((CHRIS, 1996)).

- LARGE FIRE PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 116 (ERG, 2004)
- TANK FIRE PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 116 (ERG, 2004)
Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Cool containers with flooding quantities of water until well after fire is out. Do not direct water at source of leak or safety devices; icing may occur. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. For massive fire, use unmanned hose holders or monitor nozzles; if this is impossible, withdraw from area and let fire burn.
- NFPA Extinguishing Methods for CAS75-02-5 (NFPA, 2002):
- To fight a fire involving vinyl fluoride, it is important to stop the leak (flow of the liquid/gas). Let the fire burn. Approach the fire with extreme caution. Avoid breathing vapors. Utilize water as a fog, in flooding quantities, to cool affected containers/structures or to protect those attempting to shut off the leak. Apply water from as great a distance as possible (AAR, 1994; ((CHRIS, 1996); Lewis, 1994).
EXPLOSION HAZARD
- This compound presents a dangerous explosion hazard. Extended exposure to high heat can cause the material to polymerize violently. When subject to flame, tank cars or cylinders can violently rupture and rocket ((CHRIS, 1996); Lewis, 1994).
- Vinyl fluoride vapor may explode if ignited in an enclosed space ((CHRIS, 1996)).
DUST/VAPOR HAZARD
- Vinyl fluoride emits toxic fluoride fumes when heated to decomposition (Lewis, 1994).
REACTIVITY HAZARD
- CAUTION: This material may polymerize violently under high temperature conditions or upon contamination with other products. Polymerization will produce heat and high pressure buildup in containers which may lead to an explosion or container rupture (ERG, 2004).
- Polymerization can occur in the absence of an inhibitor ((HSDB, 1996)).
- "During ozonolysis of vinyl fluoride an explosive solid residue is produced, and the volatile ozonide, trapped at minus 63 degrees C, may explode spontaneously or during removal by syringe" (Bretherick, 1990).

For additional details see the section entitled "WHO TO CALL FOR ASSISTANCE" under the ERG Instructions. As an immediate precautionary measure, isolate spill or leak area for at least 100 meters (330 feet) in all directions. Keep unauthorized personnel away. Stay upwind. Many gases are heavier than air and will spread along ground and collect in low or confined areas (sewers, basements, tanks). Keep out of low areas.
- If vinyl fluoride is involved in a fire and it becomes uncontrollable, or if a container is exposed to direct flame, consider evacuation in a 1/2 mile radius. If it is not on fire, consider downwind evacuation; distance based on amount of spilled material, weather conditions, and location (AAR, 1994).

CONTAINMENT/WASTE TREATMENT OPTIONS
SPILL OR LEAK PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 116 (ERG, 2004) ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). All equipment used when handling the product must be grounded. Stop leak if you can do it without risk. Do not touch or walk through spilled material. Do not direct water at spill or source of leak. Use water spray to reduce vapors or divert vapor cloud drift. Avoid allowing water runoff to contact spilled material. If possible, turn leaking containers so that gas escapes rather than liquid. Prevent entry into waterways, sewers, basements or confined areas. Isolate area until gas has dispersed.
RECOMMENDED PROTECTIVE CLOTHING - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 116 (ERG, 2004) Keep any possible ignition sources out of the area. Stay upwind to avoid breathing vapors. Avoid contact with the liquid. Utilize water spray to knock-down vapors. Attempt to stop the leak if this can be done without endangering anyone. Make sure this material stays out of sewers and water sources (AAR, 1994; ((CHRIS, 1996)). "At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices" ((HSDB, 1996)).
-ENVIRONMENTAL HAZARD MANAGEMENT
POLLUTION HAZARD
- Vinyl fluoride is likely released to the environment from its manufacture and use ((HSDB, 1996)).
ENVIRONMENTAL FATE AND KINETICS
Under ambient conditions this compound exists as a gas. In the atmosphere, vinyl fluoride is expected to react with photochemically produced hydroxyl radicals; estimated half-life of about 1.5 days. It will also be degraded by reaction with ozone; estimated half-life of approximately 16 days ((HSDB, 1996)).
SURFACE WATER If released to water, it will evaporate. Volatilization half-lives of 2 hours for a model river and 23.5 hours for a model pond have been demonstrated. Adsorption to sediment and bioconcentration are not thought to be significant routes ((HSDB, 1996)).
BIODEGRADATION
- There is not enough data to understand the relative significance of biodegradation in water and soil prior to or in instances that preclude evaporation ((HSDB, 1996)).
