** diving w/in 50 feet of an active suction (located on SAME side of keel) that have suction of 50gpm or more IS NOT AUTHORIZED unless considered an emergency repair and is authorized by both CO’s parties.
** maintaining less than 50gpm suction and is less than 50 feet away or maintaining more than 50gpm and is less than 50 feet away but on OPPOSITE side of keel is dive sup shall determine if it’s safe to dive. I
what are the DISADVANTAGES of IN WATER DECOMPRESSION? (6)
1- time consuming
2- uncomfortable
3- inhibits the ability of the support vessel to get underway.

* weather
* threatened enemy action
* operating schedule constraints.
5- delays medical treatment
6- increases the possibility of severe chilling and accident. U
what is SAFEWAY OUT? (8)
1- diver has trouble compressing to 50’ in chamber due to difficult equalizing.
2- compress to deepest depth possible diver can attain.
3- begin o2 breathing while continue to compress diver.
4- usually 20’ to 30’ feet.
5- if surD, was attempted and diver left 20’ in water or o2, try to compress to 20’ in chamber.

1- FOR EMERGENCIES such as:
2- switch to secondary air

what is a DIVE INCIDENT? (2)
