150 OPERATIONAL AND EMERGENCY BILLS 



Diving Operations 



Unless an actual emergency exists, support diving will in all cases be governed by existing 

 regulations. All current publications as to weather and state of sea conditions must be adhered 

 to. The diving officer on board the staging vessel will in all cases have the final say as to 

 whether or not diving operations will be allowed. 



Safety Swimmers 



Two men will be assigned to act as safety swimmers during diving operations. The duties 

 of these men will include keeping a vigil for any emergency. They will have at their disposal 

 a complete set of diving gear and a safety boat. Both the diving gear and the boat will have 

 been checked out prior to diving operations and be maintained in the standby conditions.

Two Mk VI rigs - charged with 68% He/32% O2 



Two aqualungs fully charged 



Two sets of fins 



Two face masks 



Two life jackets

All further diving operations will cease. The standby swimmers will immediately render

 for use. A Minute Man Resuscitator will be available at all times. 



General Surface Dive Procedures for Operation Sealab II 



Normal diving needs during Operation Sealab will require four divers per day. An emer- 

 gency standby team comprised of two divers will be assigned for each 24-hour period, com- 

 mencing at 0700. Rotation of divers will be such as to allow one day out of three without deep 

 diving exposure whenever possible. 



Surface dives to be made on the project will involve diving to depths beyond maximum 

 working limits outlined in the Diving Manual; therefore, strict adherence to the following 

 safety procedures must be observed: 



1. All bottles used will be gaged and pressures logged on the dive sheet immediately prior 

 to the dive. 



2. The following equipment must be worn on all surface dives made: 



Life jacket 

 Knife 

 Depth gauge
