Current through Register 2024 Notice Reg. No. 28, July 12, 2024
This Appendix contains guidelines that will be used
							 in conjunction with Section
							 6050(a)(1)(E) to
							 determine those scientific diving programs which are exempt from the
							 requirements for commercial diving. The guidelines are as follows:
1. The Diving Control Board consists of a majority of
							 active scientific divers and has autonomous and absolute authority over the
							 scientific diving program's operations.
2. The purpose of the project using scientific diving
							 is the advancement of science; therefore, information and data resulting from
							 the project are non-proprietary.
3. The tasks of a scientific diver are those of an
							 observer and data gatherer. Construction and trouble-shooting tasks
							 traditionally associated with commercial diving are not included within
							 scientific diving.
4. Scientific diver, based on the nature of their
							 activities, must use scientific expertise in studying the underwater
							 environment and, therefore, are scientists or scientists in
							 training.

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(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.

(a) Decompression tables. Decompression shall
						be in accordance with the following specified decompression tables contained in
						Volume 2, Chapter 9 of the U.S. Navy Diving Manual, Revision 6, April 15, 2008,
						which is hereby incorporated by reference.
(1)
						No-Decompression Limits and Repetitive Group Designation Table for
						No-Decompression Air Dives -- Table 9-7. This table shall be used to determine
						the no-decompression limits and the repetitive group designators for work in a
						compressed air environment that does not require decompression.
(2) Air Decompression Table -- Table 9-9.
						This table shall be used to determine the decompression schedules and
						repetitive group designators for work in a compressed air environment that
						requires decompression.
(3)
						Residual Nitrogen Timetable for Repetitive Air Dives -- Table 9-8. This table
						shall be used to determine the Residual Nitrogen Time when an employee who has
						some residual nitrogen in his/her system begins work in a compressed air
						environment.
(4) Sea Level
						Equivalent Depth -- Table 9-4. This table shall be used to correct the sea
						level decompression tables for use at altitudes of 1,000 feet above sea level
						and higher.
(5) Repetitive Groups
						Associated with Initial Ascent to Altitude -- Table 9-5. This table shall be
						used to adjust decompression schedules when an employee who is not fully
						equilibrated at altitude begins work in a compressed air environment.
(6) Required Surface Interval Before Ascent
						to Altitude After Diving -- Table 9-6. This table shall be used to determine
						when it is safe for an employee to fly or ascend to higher altitude after
						performing work in a compressed air environment.

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) There shall at all times be a qualified
						gauge tender on duty at the air control valves to regulate the pressure in the
						working areas. During tunneling operations, one gauge tender may regulate the
						pressure in not more than two headings provided that the gauges and controls
						are all in one location. In caisson work there shall be a gauge tender for each
						caisson.

						power supply to the other shall be done periodically to ensure the workability
						of the apparatus in an emergency.
(f) Duplicate low pressure air feed lines and
						regulating valves shall be provided between the source of air supply and a
						point beyond the locks with one of the lines extending to within 100 feet of
						the working face.

						rapid decompression all air supply lines shall be equipped with check
						valves.
(h) Low pressure air shall
						be regulated automatically. In addition, manually operated valves shall be
						provided for emergency conditions.
(i) The air intakes for all air compressors
						shall be located at a place where fumes, exhaust gases, and other air
						contaminants will be at a minimum.
(j) Gauges indicating the pressure in the
						working chamber shall be installed in the compressor building, the lock
						attendant's station, and at the Field Office of the employer's
						representative.
(k) There shall be
						effective communication at all times between the following:
(1) The working chamber face;
(2) The working chamber side of the air lock
						near the door;
(3) The interior of
						the air lock;

						of this Section apply to the placement, use, maintenance, and testing of
						portable fire extinguishers provided for the use of employees. Section (d) of
						this section does not apply to extinguishers provided for employee use on the
						outside of workplace buildings or structures. Where extinguishers are provided
						but are not intended for employee use and the employer has an emergency action

						3220 and
						3221 then only the requirements of
						Sections (e) and (f) of this Section apply.
(b) Exemptions.
(1) Where the employer has established and
						implemented a written fire safety policy which requires the immediate and total
						evacuation of employees from the workplace upon the sounding of a fire alarm
						signal and which includes an emergency action plan and a fire prevention plan
						which meet the requirements of Sections
						3220 and
						3221 and when extinguishers are not
						available in the workplace, the employer is exempt from all requirements of
						this section unless a specific Section in Title 8 requires that a portable fire
						extinguisher be provided.
(2) Where
						the employer has an emergency action plan meeting the requirements of Section
						3220 which designates certain
						employees to be the only employees authorized to use the available portable
						fire extinguishers, and which requires all other employees in the fire area to
						immediately evacuate the affected work area upon the sounding of the fire
						alarm, the employer is exempt from the distribution requirements in Section (d)
						of this Section.
