Respiratory oxygen
For many applications in the medical field, oxygen or oxygen enriched air is used for treatment in equipment such as oxygen masks, oxygen tents, incubators and hyperbaric chambers.There is a risk of oxygen enirchment near exhausts from such equipment, resulting in a greatly increased fire hazard. To reduce the possibility of ignition, all open flames and spark producing equipment must be avoided.
Smoking and the use of cosmetic oil and grease should be strictly forbidden. Precautions should be taken to avoid static electricity.
