§ 10.1 Policy governing coal analyses.

The Bureau of Mines makes analyses of coals primarily on behalf of Federal agencies. However, the Bureau will make analyses of coals for a non-Federal applicant in the following instances when such work can be done without hindrance to other Bureau functions:

(a) To check laboratory techniques, methods, and results at the request of a laboratory engaged in coal analysis.

(b) In cases involving disputes where the laboratory analyses previously obtained by the parties are in conflict.

(c) In cases where non-Federal applicants are investigating coal deposits by core drilling and other geologic methods, provided the data from such investigations are to be published, either by the Bureau or the applicant.

(d) In any other cases which the Director, Bureau of Mines, determines to be in the public interest.

§ 10.2 Applications.

Requests of non-Federal applicants for coal analyses should be sent in duplicate to the Regional Director, Region V, Bureau of Mines, Central Experiment Station, 4800 Forbes Avenue, Pittsburgh, Pennsylvania, 15213.

Mines Revision of Technical Paper 133 (1950), "Handbook on Coal Sampling", by N. H. Snyder.) Samples should be sent, transportation charges prepaid, to the Regional Director, Region V, Bureau of Mines, Central Experiment Station, 4800 Forbes Avenue, Pittsburgh, Pa., 15213. Each sample of coal should be accompanied by identification showing the name of the applicant, the name of the coal bed and of the mine from which the coal came, the exact location where the sample originated in case of mine or core drill sample, the place of delivery in case of a sample of delivered coal, the State and county in which the mine (or coal bed in case of core drill sample) is located, and the shipping point or town nearest the mine or drill site.

(b) Every non-Federal applicant except a State governmental agency must pay the fees specified in § 10.4 by check, bank draft, or money order payable to the order of the Treasurer of the United States. All fees should be transmitted to the Regional Director, Region V, Bureau of Mines, Central Experiment Station, 4800 Forbes Avenue, Pittsburgh, Pennsylvania, 15213.

(b) Fees for tests not included in the above list will be based on the cost of the services required, and the applicant will be notified accordingly. The fee shall be paid before such tests are begun. [Sched. 3C, 29 F.R. 7318, June 5, 1964]

(b) "Bureau" means the Bureau of Mines of the U.S. Department of the Interior.

(c) An "approved" apparatus is one conforming to the requirements of this part and having a certificate of approval to that effect.

(d) A "certificate of approval" is a formal document issued by the Bureau stating that the apparatus has met the requirements of this part. It authorizes the use and attachment of an official approval label or marking to indicate this.

(e) A "closed-circuit" apparatus is one in which the exhaled air is rebreathed by the wearer after the carbon dioxide has been effectively removed and the oxygen concentration restored.

(f) An "open-circuit" apparatus is one from which exhaled air is vented to the atmosphere and not rebreathed.

(g) A "demand-type" apparatus is an open-circuit apparatus in which the pressure inside the facepiece in relation to the immediate environment is positive during exhalation and negative during inhalation.

(h) A "pressure-demand type" apparatus is an open-circuit apparatus having positive pressure inside the facepiece in relation to the immediate environment during both exhalation and inhalation.

(i) A "self-rescue apparatus" is an open- or closed-circuit apparatus for use only during emergency escape from irrespirable atmospheres and shall not be used for entry into such an atmosphere.

(j) "Entry into and escape from" means that the apparatus approved for these purposes may be used to enter an irrespirable atmosphere and/or to escape from it.

(k) "Auxiliary equipment" is a selfcontained breathing apparatus that is limited when used underground in mines, tunnels, and similar operations to situations in which the wearer has ready access to fresh air and at least one crew of five or six men equipped with approved self-contained breathing apparatus, preferably of 2 hours or longer rating, is in reserve at a fresh air base.

(1) A "combination apparatus" is a self-contained breathing apparatus which combines the functions and purpose of a self-contained breathing apparatus with those of another type of respiratory protective device described in another part.

(m) "Compressed breathing gas" is oxygen or air stored in the apparatus and supplied to the wearer in a gaseous form.

(n) "Liquefied breathing gas" is oxygen or air stored in the apparatus in liquid form and supplied to the wearer in a gaseous form.

(o) "Applicant" means an individual, partnership, company, corporation, association, or other organization that designs, manufactures, assembles, or controls the assembly of an apparatus and that seeks a certificate of approval thereof.

By appointment, applicants or their representatives may visit the Bureau's Health and Safety Research and Testing Center, 4800 Forbes Avenue, Pittsburgh, Pa. 15213, to discuss with qualified Bureau personnel proposed self-contained breathing apparatus to be submitted in accordance with the regulations of this part. No charge is made for such consultation and no written report thereof will be made to the applicant.

§ 11.4 Types of apparatus.

(a) Types of apparatus covered by the requirements of this part are classified according to their use as follows:

(1) An apparatus for entry into or escape from oxygen-deficient atmospheres or irrespirable vapors, gases, or aerosols.

(2) Apparatus for escape only from oxygen-deficient atmospheres or from irrespirable vapors, gases, or aerosols.

(b) Apparatus covered by the requirements of this part are further classified according to their design as:

(1) Closed-circuit apparatus. (i) Compressed-oxygen;

(ii) Oxygen-generating;

(iii) Liquid-oxygen.

(ii) Pressure-demand type.

(3) Combinations of closed-circuit and open-circuit apparatus. An apparatus of this type shall meet the applicable requirements of both closed-circuit and open-circuit classifications.

(c) Apparatus covered by the requirements of this part are also classified according to the length of time they will provide respiratory protection (as determined by the Bureau's tests) as follows: (1) Four hours.

(2) Three hours.
(3) Two hours.
(4) One hour.

(5) Thirty minutes.
(6) Fifteen minutes.
(7) Ten minutes.

(8) Three minutes.

Only apparatus classified for 15 minutes service time or longer, except as indicated below, will be approved for purpose of entry into and escape from an irrespirable atmosphere. Apparatus with a rated service time of 3 minutes or 10 minutes will not be approved for entry into an irrespirable atmosphere, except as indicated below. The maximum rated service time for any self-contained breathing apparatus for self-rescue is 30 minutes. A combination self-contained breathing apparatus for self-rescue and air-line respirator (supplied-air respirator) described in paragraph (b) of § 11.22, with a 3- or 10-minute self-contained service time air supply, may be used for entry into an irrespirable atmosphere, providing entry is made using the air line air supply. A combination self-contained breathing apparatus for self-rescue and air-line respirator (supplied-air respirator) with a 15- or 30minute self-contained service time air supply, may be used for entry into an irrespirable atmosphere, providing entry is made using the air-line air supply or providing not more than 20 percent of the available self-contained air supply is used for entry. Apparatus classified for less than 1-hour service time will not be approved for use in underground mining, tunneling, and similar operations except as auxiliary equipment. Apparatus with a rated service time less than one-half hour will not be approved as auxiliary equipment.
