DON'T use oil with oxygen.
The reaction when these two substances come in contact is more
violent than igniting dynamite. Keep oil or grease away from oxygen
cylinders, cylinder valves, and other equipment. Clean hands of oil or
grease before using oxygen apparatus.
DON'T wear greasy clothes, gloves, etc., when working with oxygen.
Oxygen will cause substances with merely a trace of oil or grease
thereon to burn with great intensity.
DON'T use inflammable substances near oxygen. Oxygen itself will not
burn but will greatly accelerate combustion.
