1.2 Cautions
☻ Don’t smoke while using your oxygen equipment or when you are near a person
utilizing oxygen therapy.keep matches,cigarettes,burning tobacco,or candles away
from the area where the system is being stored or operated.
☻ Use No Oil or Grease:A spontaneous and violent ignition may occur if oil,grease,or
other petroleum substances come into contact with oxygen under pressure.keep these
substances away from the oxygen system,tubing and connections,and any other oxygen
source.Don’t use any petroleum based or other lubricants.
☻ Don’t leave oxygen equipment running when not in use.Don’t leave cannula
