OPERATIONAL AND EMERGENCY BILLS 161 



3. In general, the topside commanders will confer with the bottom commander whenever 

 feasible; however, all orders issued by topside commanders will be considered mandatory. 



4. When in the opinion of the bottom commander that the Sealab structure must be evac- 

 uated, he will order all personnel to the Personnel Transfer Capsule and so notify the topside 

 commanders. The topside commanders will render the final decision as to decompress or 

 hold, pending further evaluation of the situation. 



ACCIDENT OR ILLNESS EMERGENCY PROCEDURES 



1. In the event that the Senior Medical Monitor determines that the treatment of an ac- 

 cident or illness is beyond the capabilities of the hospital corpsman, the subject can be brought 

 to the surface in the Personnel Transfer Capsule. 



2. The Senior Medical Monitor may elect to send qualified personnel into the Sealab habi- 

 tation for treatment of any casualty or call for the evacuation of the subject to the surface. 



3. In the event it becomes necessary to bring a subject to the surface in the Personnel 

 Transfer Capsule, a surface- support diver shall be provided to serve as a tender. 



4. Subject and tender shall be transferred to the Deck Decompression Chamber for decom- 

 pression and treatment, as determined by the Senior Medical Monitor. The Senior Medical 

 Monitor may elect to return the subject to the Sealab habitat, in which case decompression 

 would not proceed. 



LOSS OF PRESSURE OR FLOODING EMERGENCY PROCEDURES 



1. In the event of a pressure loss with flooding, it will be necessary to utilize damage- 

 control materials and procedures. Immediately upon sounding the alarm, the bottom com- 

 mander will designate one man to monitor communication system topside, with a continual 

 flow of information, minimizing the need for topside to ask current status. 



2. Should efforts to correct the loss of pressure or to stem the flooding meet with failure, 

 all subjects will proceed to the Personnel Transfer Capsule and be brought topside for transfer 

 to the Deck Decompression Capsule. 



3. The Senior Medical Monitor and On-Site Commander will make the decision to decom- 

 press or hold pressure, pending an evaluation of the habitability of the dwelling. 



4. An evacuation order issued by topside will be considered mandatory. 



FIRE 



1. With the concentration of oxygen levels established for Sealab H, it is unlikely that fire 

 of significant proportions can occur. Severe electrical short circuit, however, could burn in- 

 sulation and produce atmospheric contaminants. 



2. In the event a fire is detected, the oxygen supply system must be secured. 



3. If a fire alarm is sounded, the bottom commander will designate one subject to man the 

 communication system to provide a flow of information topside. 



4. Those individuals designated by the bottom commander to fight fires will don the emer- 

 gency air-breathing masks, and proceed to take corrective measures. All other subjects will 

 evacuate to the Personnel Transfer Capsule to await further instructions. 



5. Orders to evacuate issued by topside will be considered mandatory.
