30 ammonia ice machines, or carrying cargo liable to create dangerous at- mospheric mixtures should be equipped with suitable all purpose canister gas masks (or equivalent) of types ap- proved for the required service by the United States bureau of mines. The location of such equipment should be generally made known and all per- sons liable to require its use should be anda and drilled in the use there- of. (b) Metal Cutting Outfit—Dis- tortion of the steel structure in colli- sion may imprison persons whose re- lease can be effected only by cutting parts of the metal structure, and such cases would require quick action. For such emergencies an approved cutting outfit would be desirable equipment. On vessels in which electrical cur- rent is distributed and assured with reasonable certainty under all circum- stances, such may consist of an elec- trical outfit. On vessels equipped with air com- pressors, such may consist of hand- operated compressed air tools pro- vided that there is a compressed air piping system with outlets for con- venient hose connections and sufficient air hose to reach the essential parts of the ship. A compressed air tool outfit would also serve the purpose on vessels having no stationary air compressors, by providing a _ suitable WHEN THE AMERICAN BROWN BOVERI ELECTRIC CORP. OBTAINED THE CONTRACT QUANTITY PRODUCTION METHODS WERE ADOPTED—TWO LARG ON EACH—THIS ILLUSTRATION SHOWS THE FIRST SIX BOATS BEFORE THEY WERE LAUNCHED LAST FALL—A COMPLETED BOAT IS SHOWN ON PAGE 19 MARINE REVIEW portable motor-driven air compressor. Such may also consist of an oxy- acetylene burning outfit but when this is carried it should be stowed in a location readily accessible and unsus- ceptible to wide variations in tempera- ture and secured in a manner ensuring safe stowage but permitting easy re- moval. It should be under charge of members of the ship’s personnel com- petent to use it, either from actual experience or by special instructions. The purpose of carrying any such outfit on the vessel should be made known to all of the ship’s officers. In conclusion, it is pointed out that the proper sea-going condition of a ship should be ascertained while in port; that safety at sea can best be assured by making proper prepara- tions before proceeding on a voyage, and that this principle should be im- pressed upon ship owners and licensed officers as fundamental to the welfare and best interests of all concerned. Coast Guard Boats (Continued from Page 19) of CO, gas, with piping and control gear; one air signal horn and air compressor with motor and control; March, 1927 one heating boiler fitted with a rotary hand fuel oil pump of approxi- mately 6 gallons per minute capacity at 20 pounds per square inch pres- sure; radio motor generator; search- light; and electric windlass. The fuel oil bunker tank under service conditions has a net capacity of about 6650 gallons, while capacity of the fresh water tank is about 1500 gallons. Trials of the main engine are made at the dock with the engines delivering maximum power. After the dock trial the underway trials are held which consist of a two hour contin- uous run at full speed to test the machinery installation. The first and last boats are to have trials over a measured course to obtain per- formance data. Seven additional guard patrol boats were launched on Jan, 27 at American Brown Boveri Electric Corp., Camden, N. J. These vessels are similar to the six launched on. Nov. 30, and are part of the government contract for 33. The launchings passed off smooth- ly and were materially aided by favor- able winds which kept the ice clear.
