The Chamber of Diving and Water Sports is a govermental organisation funded in 2007 by the Egyptian Mynistry of Tourism, whose purpose is to regulate all diving and water sports activities in the country. Quoting from the CDWS About Us webpage:
The Chamber of Diving and Watersports was founded by Egyptβs Ministry of Tourism in 2007 with a goal to improve quality, safety and standard of services in the diving and watersports industry, as well as to preserve unique environment of the Red Sea.
Indeed, the Egypt Tourist Authority states that the CDWS regulates all the diving centres in Egypt (emphasis mine):
All certified diving centres and schools in Egypt provide all levels of diving trainings [...]. Their activity is regulated by the official Chamber of Diving and Water Sports (CDWS) and they all own the EUF (European Underwater Federation) international certification.
In may 2009 the CDWS published a file (link in pdf) stating the depth regulation for scuba divers. It states that:
As for the maximum depths for recreational diving:
CDWS is implementing the World Recreational Scuba Training Council (WRSTC) standards www.wrstc.com for recreational diving.
The maximum depth for diving with compressed air is 40 meters (if the training qualifications and the experience of the divers allow it)
For Enriched Air diving; the maximum depth is up to a partial pressure of Oxygen (PPO2) = 1.4 ATA (maximum depth 40 meters on single tank)
Depth limitations for different activities:
For Advanced Enriched Air the maximum depth is: 40 meters
For Decompression procedures dives (Or equivalent) the maximum depth is: 45 meters
For Extended Range dives (or equivalent) the maximum depth is: 55 meters
For Normoxic (or entry level) Trimix the maximum depth is: 60 meters
For Hypoxic (or advanced) Trimix the maximum depth is: 100meters
It would therefore seem that the diving limit for compressed normoxic air mix is 40m.
