CARELESSNESS CAUSES

ACCIDENTS

An engineer named Joe
Assembled brasses on a dynamo
To get them in plumb
Required the use of his thumb
His thoughts went astray
And the consequences he did pay
No thumb-poor Joe.

This accident actually happened.
The first assistant engineer was re-
assembling cross-head brasses on a
steam dynamo. He used his thumb
and somehow got it jammed between
the cross head and the connecting
rod. He lost the first joint and spent
6 days in the hospital recuperating.

To Joe, the reassembling of cross-
head brasses was an "old" job and it
may be that "familiarity breeds con-
tempt." He relaxed his attention and
in a brief second it happened, and
another preventable accident OC-
curred.

"Stay alert-don't get hurt" is a
good motto to practice. Every time
you see Joe's hands now he has a
perpetual reminder of what one brief
second's lapse of attention can do.
Carelessness causes accidents, which
may take forever to overcome.

Carelessness, in some degree, is the

1 A notice regarding the proposed

changes in the regulations about num-

bering undocumented vessels was pub-

lished in the Federal Register, dated

September 27, 1946 (11 F. R. 11014), and

a public hearing was held by the Mer-

chant Marine Council on October 22,

1946, at Washington, D. C. All the writ-

cause of one out of every two ship-

board injury cases.

As hours in a hospital go slowly by

From the loss of a hand or a foot

or an eye,

You probably ask the reason why

The cost of carelessness is so high.

A LINE "BITE" IS DANGEROUS

Sailors are reputedly adept at han-

dling lines-both ashore and afloat.

But this adeptness does not alone pre-

vent serious accidents. When the

lines are "paying" out or being

brought "taut" it often requires nim-

bleness and quick thinking to stay

"clear." But let's not go too far afield

and instead examine a few of the re-

cent reports on injury cases involving

handling of lines aboard ships.

1. The slack was being taken out

of the aft spring line with the chief

mate in charge. The boatswain

started the winch and in putting the

bight of the line around the fair lead

got his left hand caught under the

line, crushing three fingers.

2. A deckhand handling lines on a

barge locking on the Mississippi River
lost his leg when he got caught in the
bight of a line. This accident hap-
pened at 1 o'clock in the morning and
the location of the bitts to which he
was securing his line was in the

shadow cast by the lights on the lock

and he did not notice the position of

his line before it was too late.

3. From a ship we received a re-

port of the painful injuries suffered

by a deckhand who tripped trying to

jump over a mooring cable. Negli-

gence? Yes. There was no urgency

existing that made such haste neces-

sary.

4. A deckhand on a Great Lakes

steamer ruptured himself pulling up

a long length of hawser from the fan-

tail. Negligence? Yes, again. He

should not have attempted the job

alone.

These accidents are often consid-

ered the results of occupational haz-

ards. But as accidents they are pre-

ventable. To be preventable you have

to be alert and know what can hap-

pen under certain circumstances. Of-

ten the accident occurs faster than

the eye can see when handling lines;

that the "bite" in the "bight" of a

line can be fearful indeed.

AUTHORITY: §§ 29.8 to 29.28, inclusive,
issued under sec. 1, 40 Stat. 602; 46 U. S. C.
283; Reorg. Plan No. 3, 1946; 11 F. R. 7875.
Statutes giving additional authority are
cited in parentheses at the end of af-
fected sections.

§ 29.8 Basis and purpose of num-

bering regulations. By virtue of the

authority vested in the Comman-

dant of the Coast Guard under sec-

tion 101 of the Reorganization Plan

No. 3 of 1946 (11 F. R. 7875) and the

act of June 7, 1918, as amended (46

U. S. C. 288), the regulations in this

part are prescribed to provide ade-

quate means for numbering of un-

documented vessels in accordance

with the intent of the statute and to obtain its correct and uniform administration.

§ 29.10 Vessels required to be numbered. The following undocumented vessels are required to be numbered:

(a) All vessels equipped with permanently installed motors.

(b) All vessels over 16 feet in length equipped with detachable motors.

§ 29.12 Vessels not required to be numbered. (a) The following undocumented vessels are not required to be numbered:

(1) All vessels not exceeding 16 feet in length temporarily equipped with detachable motors.

(2) Public vessels.

(3) Motor lifeboats carried as lifesaving equipment on inspected vessels. (b) The words "temporarily equipped with detachable motors" shall be construed to mean outboard motors which are clamped or otherwise temporarily fastened as distinguished from outboard motors bolted or otherwise permanently secured. The controlling principle shall be whether or not the vessel has permanently installed motors rather than the design or construction of the vessel.

(c) Undocumented vessels listed in paragraph (a) of this section will not be numbered except upon instructions of the Commandant.

$ 29.14 Application for certificate of award of number. (a) The owner of any undocumented vessel however acquired, or his duly authorized agent, shall make application for a certificate of award of number to the Officer in Charge, Marine Inspection, United States Coast Guard, having jurisdiction over the area in which the vessel is owned. If the boat is to be in the possession of a person other than the person who holds title thereto under a conditional sales or retain title contract or similar arrangement under which title does not pass, the application shall be made by the person who holds legal title.

(b) Upon purchasing or acquiring a vessel which previously has been issued a certificate of award of number, and after completion of the bill of sale on the reverse side of the certificate of award of number (Form CG 1513) by the vendor or the former owner, the purchaser will execute the application for number for undocumented motor vessel, which is incorporated on the reverse side of the certificate of award of number, and surrender the certificate, bill of sale, and application for a new number which are all on Form CG 1513) to

*Not filed with the Division of the Federal Register.

the Officer in Charge, Marine Inspection, within the statutory period of 10 days.

(c) In the case of new vessels or in the case of vessels which have not been previously numbered or in the case of vessels which have been issued the old form of certificate of award of number (NAVCG 1513), which does not contain the application, the owner of the vessel or his duly authorized agent shall make the application in duplicate for a number on Form CG 1512,2 application for number for undocumented motor vessel, and shall surrender this form, after completion, together with documentary evidence of ownership or the certificate of award of number with the bill of sale properly executed, to the proper Officer in Charge, Marine Inspection.

§ 29.16 Documentary evidence of ownership. The Coast Guard District Commander or the Officer in Charge, Marine Inspection, who receives the application for an award of number will satisfy himself that the applicant has legal title to the vessel. Any case in which ownership or legal title is in doubt will be referred to the Commandant. Original ownership may be proved by the purchaser as follows: (a) Bill of sale.

(b) Receipted bills for material used in construction.

(c) Statement of reputable boat building concern signed by an owner, officer or duly authorized agent thereof that the boat was constructed for the applicant in its factory or yard.

(d) In the case of vessels sold as surplus property by the United States Maritime Commission or the War Shipping Administration, the papers furnished the successful bidder in the form of a sale order or certificate of delivery of vessel, as the case may be, shall be accepted as sufficient evidence of ownership.

(e) Such other evidence of ownership as is acceptable to the Coast Guard District Commander or the Officer in Charge, Marine Inspection.

§ 29.18 Award of number. A number will be awarded by the Officer in Charge, Marine Inspection, upon receipt of the application together with proof of ownership and a letter, in lieu of the certificate, will be issued by him, authorizing the vessel to be operated, pending issuance of the certificate. The Coast Glard District Commander will issue the certificate of award of number in all instances except where he has designated and authorized officers or employees under his command to issue such certificates in his behalf.

§ 29.20 Certificate of award of number kept on board undocumented vessel. (a) The certificate of award of number for an undocumented ves

sel shall be kept on board at all times and shall be accessible to the person in charge except when such certificate is in the custody of the Coast Guard District Commander or the Officer in Charge, Marine Inspection. This requirement, however, does not apply to any vessel not exceeding 17 feet in length, measured from end to end over the deck, excluding sheer, nor to any vessel regardless of length if the design of fittings is such that the carrying of the certificate of number on board would render it imperfect, illegible or would tend to destroy its use as a means of ready identification.

(b) In the case where a letter is issued assigning a number previous to the issuance of a certificate of award of number, the new owner may operate such vessel without penalty for failure to have such certificate of award of number if the letter is carried and produced when necessary for identification. (R. S. 5294, as amended, sec. 21, 54 Stat. 167, 18 U. S. C. 642, 46 U. S. C. 526t)

§ 29.22 Sales of undocumented vessels to aliens. For the duration of the war the issuance of a certificate of award of number to a vessel, the sale or transfer of which, in whole or in part, is subject to section 37 of the Shipping Act, 1916, as amended (46 U. S. C. 835), shall be subject to the United States Maritime Commission's General Order 58, as revised (10 F. R. 14210). For a vessel less than 1,000 gross tons and not documented under the laws of the United States, General Order 58 gives blanket approval to the sale, mortgage, lease, charter, delivery, or transfer and agreement for the sale, mortgage, lease, charter, delivery, or transfer to any person not a citizen of the United States of any vessel or interest therein owned in whole or in part by any person who is a citizen of the United States or by a corporation organized under the laws of the United States or of any state, territory, district or possession thereof. For a vessel documented under the laws of the United States or a vessel 1,000 gross tons or over, prior approval of the sale by the Maritime Commission is required.

§ 29.24 Owner furnishing information when changes occur. (a) The owner of a numbered vessel shall notify the Coast Guard District Commander or Officer in Charge, Marine Inspection, within ten days, if:

(1) The vessel is lost, destroyed, or abandoned.

(2) The vessel is transferred from one person to another; or

(3) He moves his permanent residence to a place in another customs district or to a place within the jurisdiction of another Coast Guard District Commander.

(b) In the case of change of ownership, loss, destruction, or abandonment of a numbered vessel, the notice shall be accompanied by a surrender of the certificate of award of number if it is in existence.

§ 29.26 Procedure upon change of permanent residence. If the owner has moved his permanent residence to a place in another customs district or to a place within the jurisdiction of another Coast Guard District Commander, the original number will be retained by the vessel and the owner's change of permanent residence shall not be a cause for the surrender of the certificate except under special instructions of the Commandant. However, vessels sold into another customs district or Coast Guard district may be renumbered anew.

§ 29.28 Number assigned required on bows of undocumented vessel. (a) Every undocumented vessel required to be numbered shall have the number awarded or assigned painted on or attached to each bow so that the number reads from left to right.

(b) The number shall be in block characters of good proportion, not less than three inches in height, and parallel with the water line as near the forward end of the bow as legibility of the entire number for surface and aerial identification permits. The number shall be located as high above the water line as practicable, but in no case less than three inches from the bottom of the numbers to the water line.

(c) The numbers shall be of a color which will contrast with the color of the hull so as to be distinctly visible and legible; i. e., if the hull is light, the color of the numbers shall be dark, or if the hull is dark, the color of the numbers shall be light. Dated: January 24, 1947. [SEAL]

Part 31 is amended by adding a new § 31.1-7'' reading as follows:

§ 31.1-7 Equipment installations on vessels during World War IITB/ALL. Boilers, pressure vessels,

By virtue of the authority vested in me, I find that an emergency exists and the following amendments to the regulations are prescribed and shall become effective upon the date of publication of this order in the Federal Register.

It is found that the critical shortage of certain materials during the war caused 12 F. R. 640; Jan. 29, 1947.

machinery, piping, electrical and other installations, including lifesaving, fire-fighting, and other safety equipment, installed on vessels during the Unlimited National Emergency declared by the President on May 27, 1941, and prior to the termination of Title V of the Second War Powers Act, as extended (Sec. 501, 56 Stat. 180; 50 U. S. C., App. Sup., 635), which do not fully meet the detailed requirements of the regulations in this chapter, may be continued in service if found to be satisfactory by the Commandant for the purpose intended. In each instance prior to final action by the Commandant, the Officer in Charge, Marine Inspection, shall notify Headquarters of the facts in the case, together with recommendations relative to suitability for retention. (R. S. 4405 and 4417a, as amended; 46 U. S. C. 375, 391a; sec. 101, Reorganization Plan No. 3 of 1946; 11 F. R. 7875)

the manufacturing of certain items to be discontinued or greatly curtailed and it became necessary in the successful prosecution of the war to issue orders under the authority of section 501 of the Second War Powers Act waiving certain requirements of the regulations in this chapter for certain equipment and installations. As the authority for the issuance of waivers under the terms of the statute, as extended, will expire on March 31, 1947, it will be necessary in all instances to comply with the requirements of the regulations in this chapter after that date.

It is hereby further found that compliance with the notice, public rule making procedure, and effective date requirements of the Administrative Procedure Act (Pub. Law 404, 79th Cong.: 60 Stat. 237) or R. S. 4417a, as amended (46 U. S. C. 391a), is impracticable and contrary to the public interest in that the time intervening between the date when information upon which these regulations are based became available and when these regulations must become effective is insufficient for such compliance, and since postponement in issuing the regulations will work an unique hardship in converting merchant vessels to peacetime operation.

The purpose of these regulations will be to permit certain equipment or installations, if found to be satisfactory by the Commandant for the purpose intended, to be continued in service so long as in good and serviceable condition.

Section 61.17 (c) is amended to read as follows:

§ 61.17 Fire-detecting and automatic sprinkling systems.

(c) Smoke-pipe systems-(1) Scope of installations. Systems of this type shall provide a detecting device to which all smoke pipes shall lead, which device shall be located in the wheelhouse, in a fire control station in which a 24-hour watch is kept, or in convenient proximity to the valves of the extinguishing system, provided there are transmitted to the wheelhouse or fire control station means for determining the compartment reporting the alarm and audible alarms are provided as required in this section.

(2) Construction and installation. (i) The detecting device shall be such that finely divided and diluted particles of smoke shall be readily indicated visually. The lighting arrangement shall be such as not to be disturbing to navigation at night. For new installations on vessels of over 5,000 gross tons or where installations are not made in the wheelhouse or fire control station, this device shall be provided with an audible alarm in the wheelhouse together with an auxiliary audible alarm located in the engine room.

(ii) Smoke collectors shall be installed overhead in each compartment protected and shall be so located that no point on the overhead deck is more than 40 feet from a collector. The indicating pipes or tubing shall be not smaller than threefourths inch inside diameter. When more than one smoke collector is required for a compartment, not more than two collectors may be connected to one indicating pipe. Each compartment shall have one or more indicating pipes extending to the detecting device, except that the pipes from small adjacent compartments not exceeding a combined volume of 5,000 cubic feet may be joined. No smoke collectors shall be located nearer to the edge of the opening of a ventilator than three times the diameter or equivalent diameter of the opening.

(iii) Sufficient quantity of the exhaust shall discharge into the wheelhouse or fire station to permit the detection of fire by odor, and a valve plainly marked and readily operable from that compartment shall be provided to direct the exhaust, if obnoxious, to the outside. Where the detecting cabinet is not installed in the wheelhouse or fire station the residual exhaust shall be discharged in the vicinity of the detecting cabinet.

(iv) Suction fans shall be furnished in duplicate, and shall be provided with switches to permit their operation from the emergency lighting circuit. Where the emergency lighting voltage is less than the normal lighting voltage, one fan shall be so arranged that it may be operated from either source.

(v) A trouble signal located in the fire control station or the wheelhouse shall be provided which will indicate the inability of the system to report a smoke alarm.

(vi) Where exposed to injury in cargo compartments the collectors and smoke pipes shall be reasonably protected against injury.

(vii) All smoke pipes shall be installed to grade to low points and at low points provided with drains. These pipes shall be run with as easy bends as practicable.

(viii) The smoke inlets in cargo holds should be examined periodically by the ship's personnel to determine whether inlets are obstructed by corrosion, paint, dust, or other extraneous condition. Smoke tests should be made in all holds and the operation of the system noted.

§ 144.01 Basis and purpose of regulations. By virtue of the authority vested in the Commandant of the Coast Guard under section 101 of the Reorganization Plan No. 3 of 1946 (11 F. R. 7875), section 5 of Act of May 27, 1936, section 2 of Act of October 9, 1940, and section 5 of Act of June 6, 1941 (46 U. S. C. 369, 463a, 50 U. S. C. 1275), the regulations in this part are prescribed for the guidance of builders in constructing new passenger vessels or in making alterations in existing passenger vessels or in converting existing vessels to passenger vessels, showing the safety and fire prevention characteristics which will meet the approval of the Commandant, so that the vessels, when built or altered, as

the case may be, can be navigated with safety to those on board.

§ 144.03 Vessels to which applicable. (a) The regulations of this part shall be applicable to the following vessels of 100 gross tons and over propelled by machinery:
