SPECIAL RESPONSE TEAMS TACTICAL DIVER
Oxygen Enriched Air for Police & Public Safety Divers
(This is NOT a Recreational Diving Course)
Police and Public Safety Divers must dive at times and in places that
other divers, given the choice, would not. This by definition is no longer
recreational diving.
Oxygen Enriched Air, commonly called "NITROX", is the breathing gas of
choice for operational dives to 110fsw/33msw.
Many jurisdictions consider police and public safety divers,
"Professional Divers". As such, these divers require Commercial Diver
Training. Recreational diving courses do not fulfill the requirements for
professional divers. The basis for this oxygen enriched air course was
originally developed for Commercial SCUBA Divers. It is designed for maximum
diver safety and benefit.
Course conduct covers both the physiological impact of diving oxygen
enriched air and the operational considerations.
Physiologically, the benefit of breathing oxygen enriched air is proven
for divers in extreme conditions. We will see why using oxygen enriched air
for extended duration and repetitive dives is beneficial, and subsequently,
why air is the least desirable breathing gas under the same circumstances.
Operationally what makes this course unique is the exclusive
EnviroDiveTable "Oxygen Enriched Air Table". During a high stress diving
operation, the last thing a diver/supervisor needs, is to have to remember the
six oxygen enriched air formulas, especially if it has been awhile since
he/she has used them. With the "EnviroDiveTable", a quick glance will give all
of the information that is required for safe diving operations. "Simple Works"
