<br />1. PRODUCT AND COMPANY IDENTIFICATION
<br />Product Name: Zythor
<br />Chemical Name: Sulfuryl fluoride
<br />Company: Ensystex II, Inc.
<br />Address: 2709 Breezewood Ave., Fayetteville, NC 28303
<br />Daytime Phone: 1-800-398-3772
<br />2. COMPOSITION /INFORMATlON ON INGREDIENTS
<br />Sulfuryl fluoride 99.3% CAS# 2699-79-8 EINECS#: 220-281-5
<br />Carbon dioxide 0.5% CAS# 124-38-9
<br />3. HAZARDS IDENTIFICATION
<br />Compressed gas harmful by inhalation, Sulfuryl fluoride has no
<br />warning properties such as odor, color or eye irritation, Exposure to
<br />toxic and even lethal levels may occur without warning or cletection
<br />during a single exposure, Evacuate Immediate area if leak occurs.
<br />Releases hydrogen fluoride upon decomposition by high heat.
<br />4, ARST-AID
<br />In all cases of overexposure, when symptoms such as nausea, difficulty in
<br />breathing, abdominal pain, slowing of movements and speech or numbness
<br />in extremities are exhibited, get medical attention immediately. Take
<br />affected person to a doctor or emergency treatment facility.
<br />Inhalation: Move person to fresh air. If person is not breathing, call 911 or
<br />an ambulance, then give artificial respiration, preferably by mouth-to-mouth,
<br />if possible. Excessive exposure may severely irritate upper respiratory
<br />tract. Consult a physician in all cases.
<br />Eye Contact: Hold eye open and rinse slowly and gently with water for at
<br />least 15-20 minutes. Remove contact lenses, if present, after the first 5
<br />minutes, then continue rinsing eye. liquid fumigant in the eye may cause
<br />damage due to refrigeration or freezing.
<br />Skin Contact: Immediately apply water to contaminated area of clothing
<br />before removing. Once area has thawed, remove contaminated clothing,
<br />shoes and other items covering skin. Rinse skin immediately with plenty of
<br />water for 15-20 minutes.
<br />Note to Physician: Sulfuryl fluoride is a gas that has no waming
<br />properties such as odor, color or eye irritation. (Chloropicrin, (CAS# 76-06-
<br />2) which is used as a waming agent in conjunction with sulfuryl fluoride, is
<br />the active ingredient in tear gas and will cause tearing.) Early symptoms of
<br />exposure to sulfuryl fluoride are respiratory irritation and central nervous
<br />system depression. Excitation may follow. Slowed movement, reduced
<br />awareness and slow or garbled speech may be noted. Such individuals
<br />should rest in bed for at least 24 hours. Prolonged exposure can produce
<br />lung irritation, pulmonary edema, nausea and abdominal pain. Repeated
<br />exposure to high concentrations can result in significant lung and kidney
<br />damage. Single exposures at high concentrations have resulted in death.
<br />Treat symptomatically.
<br />5. FIRE-AGHTlNG MEASURES
<br />Extinguishing Media: This product does not bum. All means of
<br />extinguishing are acceptable. If cylinders are in a fire area, remove them if
<br />possible. Altemately, water can be used to keep them cool to prevent
<br />discharge of product due to the melting of fusible plugs in the cylinder
<br />valves which will occur at temperatures above 1580F. Use of water may
<br />also help to scrub out part of any hydrofluoric acid and sulphur dioxide
<br />which may be formed by decomposition of the product in a fire.
<br />Hazardous C6mbustion Products: At temperatures above 7520F, sulfuryl
<br />fluoride will decompose into hydrogen fluoride and sulfur dioxide.
<br />Fire fighting Equipment: Firefighters should wear protective clothing and
<br />use self-contained breathing apparatus. When fighting fires in atmospheres
<br />containing potentially high concentrations of sulfuryl fluoride, encapsulating
<br />protective suits should be wom due to possible formation of hydrofluoric
<br />acid. Protective suit material should be compatible with exposure to
<br />hydrofluoric acid.
<br />6. ACCIDENTAL RELEASE MEASURES
<br />Personal Precautions: Wear appropriate safety clothing, respiratory
<br />protection devices and eyelface protection (see Section 8). Evacuate
<br />unprotected personnel that are nearby.
<br />Leak Procedure: Evacuate immediate area of leak. Move leaking cylinder
<br />to an isolated location observing strict safety precautions. If safe to do so,
<br />try to stop leak. Work upwind from the cylinder, if possible. Entry into
<br />affected area(s) by persons not using approved respiratory protection
<br />devices is not permitted until the concentration of sulfuryl fluoride in the air
<br />of the affected area(s) is determined to be t ppm or less, as determined by
<br />an approved Low Fumiganl Level Delection Device (such as ExplorlR.
<br />Interscan, or Miran gas analyzer).
<br />
<br />7. HANDLING AND STORAGE
<br />Handling: Use good personal hygiene. Follow proper cylinder handling
<br />directions. See Section 8 for control measures.
<br />Storage: Keep out of reach of children. Product should be stored in
<br />compliance with local regulations. Store in a well ventilated, cool, dry area.
<br />Keep away from heat sources.
<br />8. EXPOSURE CONTROLS/PERSONAL PROTECTION
<br />Ventilation and respiratory protection information given below is applicable
<br />to handling sulfuryl fluoride during production, packaging, transportation
<br />and storage. Applicators should refer to the product Jabel for personal
<br />protection equipment requirements during application.
<br />Exposure Limits: ACGIH TLV is 5 ppm TWA, 10 ppm STEL OSHA PEL
<br />is 5 PPM TW A. Provide general and/or local exhaust ventilation to control
<br />airborne levels below the exposure limits.
<br />Respiratory Protection: Atmospheric levels should be maintained below
<br />the exposure guidelines. When respiratory protection is required or during
<br />emergency conditions, use a NIOSH approved positive pressure self-
<br />contained breathing apparatus or positive pressure airline with auxiliary
<br />self-contained air supply.
<br />HancllSkin Protection: No skin protection should be needed. Skin contact
<br />with the liquid may cause freeze damage if the liquid is confined to the skin.
<br />Do not wear gloves or rubber boots.
<br />Eye/Face Protection: Chemical proof goggles / face shield
