SOP for Propane Regulator of Biosafety Cabinet


  1. Turn blower on and open the glass panel of the biological safety cabinet before preceding. Also; check that the petcock (valve 3) is off.
  2. Check hoses inside and outside of cabinet.
  3. Make sure that valve #1 is "decreased" completely, i.e. unscrewed upwards (counter clockwise) untill loose.
  4. Slowly turn on main cylinder valve #2, until it is completely open.
