CEILING, CEILING ZONE, FLOOR AND DECOMPRESSI-

ON RANGE

When in decompression, it is important that you understand

the meaning of ceiling, ﬂ oor, and decompression range (Fig.

6.14.):

- The ceiling is the shallowest depth to which you

should ascend when in decompression. At this depth,

or below, you must perform all stops.

- The ceiling zone is the optimum decompression stop

zone. It is the zone between the minimum ceiling and

1.8 m [6 ft] below the minimum ceiling.

- The ﬂ oor is the deepest depth at which the decom-

pression stop time will not increase. Decompressi-

on will start when you pass this depth during your as-

cent.

- The decompression range is the depth range between

the ceiling and ﬂ oor. Within this range, decompressi-

on takes place. However, it is important to remember

that the decompression will be very slow at, or close

to, the ﬂ oor.

The depth of the ceiling and ﬂ oor will depend on your dive

proﬁ le. The ceiling depth will be fairly shallow when you en-

ter the decompression mode, but if you remain at depth, it will
