Q

what are the DISADVANTAGES of IN WATER DECOMPRESSION? (6)

6- increases the possibility of severe chilling and accident. U

45
Q

what is SAFEWAY OUT? (8)

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.
6- double the # of o2 periods indicated in t/s.
