(820 ILCS 245/2) (from Ch. 48, par. 262)
Sec. 2.
The working period of any person under compressed air in any
compartment, caisson, tunnel or places shall be divided into two periods
under compressed air with an interval of rest between the two periods. If
the air pressure exceeds fifteen pounds per square inch, the said interval
of rest must be spent in the open air. Persons who have not previously
worked in compressed air, when the air pressure exceeds fifteen pounds per
square inch, shall work therein only one of the two said periods during the
first twenty-four hours of their employment. Except in cases of extreme
emergency no person shall be employed or subjected to pressure exceeding
fifty pounds per square inch. The maximum number of hours to each period
and the minimum rest intervals between the periods during any twenty-four
hours for any pressure as given in columns one and two of the following
table shall be set opposite such pressure in columns three, four, five, six
and seven of said table:
PERIODS AND INTERVALS OF WORK FOR EACH
TWENTY-FOUR HOUR PERIOD

*The employer may determine the time of each period when the pressure is
not more than fifteen pounds per square inch, provided that the total for
the periods does not exceed eight hours. The limits or hours as specified
in said table shall apply according to the maximum pressure attained at any
time during the period.

Sec. 3.
No person employed in compressed air shall be permitted to pass
from the working chamber to normal air, except after decompression in a lock as follows:
(a) Where the air pressure is greater than normal and not more than fifteen
pounds per square inch, the time of decompression shall be at least two minutes;
(b) Where the air pressure is more than fifteen pounds per square inch,
and not more than twenty-six pounds per square inch, decompression shall
be at the average rate of not more than three pounds per minute;
(c) Where the air pressure is more than twenty-six pounds per square inch,
and not more than thirty-three pounds per square inch, decompression shall
be at the average rate of not more than two pounds per minute;
(d) Where the air pressure is more than thirty-three pounds per square
inch, decompression shall be at the average rate of not more than one pound per minute;
(e) Where the air pressure is more than fifteen pounds per square inch,
a stage decompression shall be used in which a drop of one-half of the maximum
gauge pressure shall be at the rate of five pounds per minute. The remaining
decompression shall be at a uniform rate and the total time of decompression
shall equal the time specified for the original maximum pressure;
(f) The time of decompression shall be posted in each man lock.
