§6080. Compression.


(a) During the compression of employees, the pressure shall not be increased to more than 3 psig within the first minute. The pressure shall be held at 3 psig and again at 7 psig sufficiently long to determine if any individuals are experiencing discomfort. After the first minute the pressure is to be raised uniformly and at a rate not to exceed 10 psi per minute. If any employees complain of discomfort, the pressure will be held to determine if the symptoms are relieved. If after 5 minutes the discomfort does not disappear, the lock attendant shall gradually reduce the pressure, until the employee signals that the discomfort has ceased. If the employee does not indicate that the discomfort has disappeared, the lock attendant shall reduce the pressure to atmospheric and the employee shall be released from the lock.

(b) No employee shall be subjected to pressure exceeding 50 pounds per square inch.

Exception: The requirements of subsections (a) and (b) do not apply in an emergency.
