Trust your nose
❌ Any air that has an odor, whether oily, acrid, sweet or of an unknown scent, is not acceptable as breathing air.
📋 When in doubt, the dive operator should be approached for their latest air quality test certificate, compressor maintenance logbook or filter replacement schedule.
🤝🏼 When you cannot be assured of some degree of quality control at a dive operation, you should consider diving elsewhere. Your health and safety is equally their responsibility.
