  • How can I safely handle refrigerants?

    BEST refrigerants were extensively tested prior to introduction. They are as safe as, or safer than, the refrigerants they replace. However, anyone working with refrigerants should always follow these safety tips:

    • Store refrigerants in a clean, dry area out of direct sunlight. Never heat cylinders above 125°F (52°C).
    • Never tamper with cylinder valves or pressure relief devices.
    • Never refill disposable cylinders with anything. Do not use disposable refrigerant cylinders as compressed air tanks.
    • Wear protective clothing such as gloves and eye protection when handling any refrigerant.
    • Avoid contact with liquid refrigerant because frostbite may occur.
    • Avoid exposure to vapors through spills or leaks.
    • Evacuate the area if a large spill occurs. Return only after the area has been properly ventilated.
    • Verify proper cylinder hookup to the system.
    • Check to be sure the cylinder label matches the color code.
    • Open cylinder valves slowly.
    • Avoid rough handling of refrigerant cylinders.
    • Verify that the system has been completely evacuated with a vacuum pump before cutting any lines.
    • Before welding or brazing, evacuate the equipment and then break the vacuum with air or nitrogen. Do not perform any repair on pressurized equipment.
    • Always ventilate the work area before using open flames.
  • How can I safely handle disposable and returnable cylinders?
    • Remove liquid from the cylinder when charging any refrigerant. Once removed from the cylinder, it can be flashed to vapor for charging.
    • Verify proper hookup of charging hoses. Do not charge to the discharge side of the compressor.
    • Open valves slowly.
    • Protect cylinders from moisture and rusting during storage.
    • Verify that the refrigerant label matches any color code or labeling used on the equipment.
    • Do not tamper with any relief devices on cylinders or refrigerant equipment.
    • Do not drop, dent, or mechanically abuse containers.
    • Do not recharge disposable or refillable cylinders with used refrigerants.
    • Do not use disposable cylinders as compressed air tanks.
    • Do not force connections.
    • Do not use flame on cylinders to heat them. Never expose cylinders to temperatures above 52°C (125°F).
  • What should I do if a large refrigerant leak or spill occurs?

    Do not attempt to enter the area to repair equipment until the vapors are dispersed, or until you are equipped with proper breathing apparatus. Evacuate everyone until the area has been ventilated. Use blowers or fans to circulate air at the floor level and in any basement or low areas.

    • Appropriate respiratory protection equipment should be readily available in case of a large release.
    • Personnel should be trained how to use this equipment.
    • Consult the most recent version of ASHRAE Standard 15 for additional information.
  • How can I tell if a refrigerant has decomposed?

    The strong odors released from the decomposed refrigerant will irritate the nose and throat. The irritating fumes released from decomposition will provide early warning and will likely result in an attempt to evacuate the area. Follow all BEST recommendations for refrigerant handling to prevent refriger­ant decomposition and other hazards.

  • Are decomposition products hazardous?

    Yes. The acidic vapors produced are dangerous and the area should be evacuated immediately and ventilated to prevent exposure to personnel. Anyone exposed to the decomposition products should be taken to fresh air and medical treatment sought immediately. The exposure area should not be re-entered until it is deemed safe by the appropriate authorities.

  • Was MAPP gas developed by BEST?

    Yes. BEST MAPP gas was developed by our experienced technicians with 3 years of continuous improvement and it was granted national invention patent. It has a higher combustion temperature and a better welding performance.

  • Does BEST MAPP gas have the similar formula as other MAPP gas?

    No. The ingredient of BEST MAPP gas is different from other MAPP gases. With high quality, low cost raw materials, we optimized the formula of MAPP gas and developed a new MAPP gas with higher quality and higher performance.

  • Where have BEST MAPP gases been exported?

    BEST MAPP gases have been exported to many countries such as the United Kingdom, Italy, Germany, Russia, and Serbian, etc..
