Hazards and Protection.
Protect against physical damage. Isolate from other storage, especially materials with which fluorine is known to react. Keep away from sources of heat and ignition.
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.
Wear appropriate protective gloves, clothing and goggles.
Wear positive pressure self-contained breathing apparatus (SCBA).
Do not touch or walk through spilled material. If you have not donned special protective clothing approved for this material, do not expose yourself to any risk of this material touching you. Do not direct water at spill or source of leak. A fine water spray remotely directed to the edge of the spill pool can be used to direct and maintain a hot flare fire which will burn the spilled material in a controlled manner. Keep combustibles (wood, paper, oil, etc.) away from spilled material. Stop leak if you can do it without risk. 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. Ventilate the area.
Reactive under confinement.
Reacts with arsenic and arsenic trioxide at ordinary temperatures,.
Decomposition water, giving hydrofluoric acid, oxygen fluoride, hydrogen peroxide, oxygen and ozone.
SMALL FIRES: Dry chemical, soda ash, lime or sand. LARGE FIRES: Water spray, fog (flooding amounts). Do not get water inside containers. Move containers from fire area if you can do it without risk. FIRE INVOLVING TANKS: 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.
Substance does not burn but will support combustion.
This is a strong oxidizer and will react vigorously or explosively with many materials including fuels. May ignite combustibles (wood, paper, oil, clothing, etc.). Vapor explosion and poison hazard indoors, outdoors or in sewers. Containers may explode when heated. Ruptured cylinders may rocket.
Toxic gases generated in fires involving fluorine.
OSHA PEL: TWA 0.1 ppm (0.2 mg/m3) NIOSH REL: TWA 0.1 ppm (0.2 mg/m3) NIOSH IDLH: 25 ppm
Both fever and chills have been reported. Lethargy with delayed-onset dyspnea was reported in mice. In one animal study, no malformations were found following injection of fluorine-ion containing dust extracts.
Respiratory tract irritation may progress to pulmonary edema.
Thermal burns or frostbite may occur.
Human volunteers exposed to up to 25 ppm have shown little irritation. Eyelid eczema may occur and attenuation of retinal arteries may result from prolonged exposure. Fluorine is irritating to nasal mucosa.
Seek medical assistance.
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Effects may be delayed.
Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists. Direct contact with fluorine liquid may produce frostbite injury.
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.
