N.J. Admin. Code § 8:21-3.6

Current through Register Vol. 56, No. 21, November 4, 2024

Section 8:21-3.6 - SCUBA recommendations

(a) The recommendations in this section are primarily directed to purveyors of SCUBA air to protect public health.

(b) Compressed air containers. No compressed air container used for self-contained underwater breathing apparatus should be filled or refilled unless it shows evidence of a recent I.C.C. hydrostatic test.

(c) Preparation of compressed air. Uncontaminated air may be compressed by means of suitable equipment and the compressed air should not exceed the limits set forth in this section. The following sampling, testing, and test procedures may be used to determine the quantitative composition of the compressed air.

1. Carbon monoxide. Determination of carbon monoxide may be made by using:

i. Mine Safety Appliance Detector Co., Carbon Monoxide Tester No. Ds-47133;

ii. U.S. Safety Services Detector, model 300 "Saf-Co-Meter";

iii. Kitagawa Precision Gas Detection Unico Model No. 400, with the cartridge No. 106A; or its equivalents;

iv. Any other device or method acceptable to the Department of Health.

2. Carbon dioxide. Determination of carbon dioxide may be made by using:

i. Kitagawa Precision Gas Detection Unico Model No. 400;

ii. Davis Emergency Co., Gas Detector Kit;

iii. Any other device or method acceptable to the Department.

3. Oil. Determination of oil may be made by passing 100 liters of air at atmospheric pressures and room temperature through a Number 41 Whatman Filter and measuring the increase in weight over the original weight of the filter. Air contamination with 0.02 milligrams of oil per liter of air will add two milligrams to the weight of the filter. Other forms of particulate matter may be similarly assayed. Assays may be made by this or by any other device or method acceptable to the Department of Health.

4. Water. Compressed air may be saturated with water vapor but should not contain water in separated form. This may be determined by using:

i. Dew point equipment as manufactured by Mine Safety Appliance Co., Foxboro Co., or American Instrument Co.;

ii. Any other device or method acceptable to the Department.

5. Odor. Compressed air may be tested for odor by cracking the valve and smelling the escaping air. Filled cylinders having any objectionable odors should be rejected.

(d) Equipment. Equipment for compressing air should be of suitable design, size, construction and location to facilitate maintenance and operation for its intended purpose in a manner that is orderly and clean. Such equipment should be:

1. So constructed that any surface that comes in contact with the air be nonreactive, nonadditive, or nonabsorptive to the finished product;

2. So constructed that any substances required for its operation, such as lubricants or coolants, may be employed without hazard or without becoming additive to the finished compressed air;

3. So constructed to facilitate maintenance to assure reliability of the finished product within the limits as set forth in section 20 of this subchapter.
