Survival At Sea (continued from page 25) vapor that puts out fire differently than any other extinguishing agent. Most other extinguishants— carbon dioxide, water, or foam— work physically. They attack fire by smothering, cooling, or separat- ing fuel from oxygen.

Halon 1301 works chemically to halt fire. It actually stops the com- bustion process itself—breaks the chain reactions that propogate from one fuel molecule to another. That's why Halon 1301 puts out fire faster, and it prevents rekindling or reflash as long as the initial concentration of Halon in the area's atmosphere is maintained. Fur- thermore, the Du Pont product is low in toxicity, does no damage to property, and leaves no residue be- hind to clean up. Nor does it rob oxygen from the air; trapped or in- jured personnel can depend on lifesaving minutes or breathable atmosphere for evacuation or rescue.

Today, Halon 1301 systems offer an unchallenged level of life safety to crews and shipyard workers in pump rooms, turbine rooms, ma- chinery spaces, and electrical and electronic equipment areas aboard ship.

GAYLORD INDUSTRIES

The submarine is the ultimate testing ground for components that make up a galley ventilation sys- tem. Though important in any sit- uation, the quality of the air leav- ing the galley area of a submarine, which has 100-percent air recircu- lation, is a critical factor.

The ventilator must be capable of removing 95 percent of the grease from the air rising above the cooking surface. The air must be thoroughly cleansed of grease, smoke, and odor, and also be cooled and dehumidifed. Following grease extraction tests by the U.S. Bu- reau of Standards, the Gaylord galley ventilator was found to meet the stringent requirements for use on the U.S. Navy submarine fleet.

This same high level of grease extraction that is maintained out of necessity in a submarine galley is standard in all commercial models of the Gaylord ventilator.

With its integral fire protection system, the ventilator offers a safe and efficient solution to the prob- lems unique to marine applications.

Gaylord Industries is one of the world's leading manufacturers of commercial galley exhaust sys- tems. The company's equipment has been standard on U.S. Navy vessels since 1953. The ventilation systems have been designed for and installed in galleys on car- riers, cargo ships, tankers, and cruise liners throughout the world.

HARVEY'S

Circle 39 on Reader Service Card

Survival time for an unpro- tected person immersed in ex- tremely cold water is a matter of minutes. The exposure suit de- signed and manufactured by

Harvey's Commercial Marine Di- vision will provide at least 13 hours of protection from exposure to cold waters. Tested by the com- pany's research and development department, the Harvey survival suit surpasses all technical speci- fications of the U.S. Coast Guard and Underwriters Laboratories!>, who have both tested and ap- proved the suits.

The Harvey suit is constructed from 3/16-inch, nitrogen-ex- panded, closed-celled neoprene rubber. All components are manu- factured in the U.S. The flotation is in the fabric; even while filled with water, the suit will not sink.

It is one-piece construction, and only a small area of the face is ex- posed when the suit is worn.

The suit can be donned in less than one minute, and with prac- tice the time can be reduced to 20 or 30 seconds. When the suit is un- rolled from its weatherproof stor- age bag, the wearer simply climbs in and zips up, fully clothed. With the attached, standard flotation inflation ring, additional buoyancy is provided. A Firefly11 strobe light, which may be placed in the hood, will provide night visibility for miles.

IMPERIAL

Circle 40 on Reader Service Card

Imperial Manufacturing Com- pany's survival suits offer the two elements necessary for survival in cold water—flotation and insula- tion from hypothermia. Imperial suits can extend the survival time of victims of marine accidents and increase their odds for rescue.

The suit is designed for quick donning, even over the bulkiest work clothing. One size fits all, from 5'4" to 6'4" and up to 300 pounds.

Tests done by the U.S. Navy

Clothing and Textile Research Unit indicate that survival times of 18 hours and more can be expected in temperatures of 35 F when worn over normal clothing. Normal sur- vival time for victims not wearing survival suits in waters of that temperature is usually less than 30 minutes.

Imperial survival suits are made of closed-cell foam neoprene. The material is the flotation, not the air in the suit. So even if the suit is torn and filled with water, it will not sink. Neoprene is an ex- cellent insulating material. The suit seals out cold and water while holding body heat inside. Even if the suit should be flooded, the water inside the zipped suit will warm and provide insulation from the cold outside. People have sur- vived 13 hours in 34-F water and an additional 22 hours on land in frigid conditions while wearing

Imperial survival suits.

WALTER KIDDE

Circle 41 on Reader Service Card

Walter Kidde marine fire pro- tection systems include Halon 1301, dry chemical, carbon dioxide, and

Lo-Ex and Hi-Ex foam concen- trates. Kidde fire protection ex- perts have the experience and technology to custom-tailor fire protection systems to meet each vessel's individual requirements.

On guard 24 hours a day, the

Kidde smoke detection systems continuously monitor air samples within multiple zones of the ves- sel, to detect the presence of smoke and provide an early warning of a potential fire problem. Essentially, the system is comprised of three principal components: a smoke de- tection cabinet, a suction fan blower cabinet, and a repeater panel.

Using axial fans, the suction blower continuously samples air from each cargo hold or fire zone, passing the air through unique de- tection modules in the smoke de- tection cabinet. Air samples are continuously drawn from each zone and are inspected by a directed light beam. The presence of smoke in the viewing path of the light source causes the light to scatter and be seen by a photocell. Once the presence of smoke is detected in any zone, the appropriate an- nunciation actions will occur to provide audible and visual warn- ing of an impending danger.

As a result of its basic modular design, the system, when coupled to a carbon dioxide supply, can also provide a fast-acting, fire suppression capability. By incor- porating a special three-way valve in each zone, CO., can be dis- charged through the "shared" de- tection/discharge piping into the appropriate fire zone.

KOSAFE A/S

Circle 42 on Reader Service Card

Kosafe A/S of Norway, a mem- ber of the Kosmos Group, has de- veloped a new horizontal revolv- ing davit system called Debarko

Safe14 to provide safer emergency escape from offshore structures and vessels. The system is de- signed and manufactured to the rules and regulations of the Nor- wegian Maritime Directorate, which demand that a lifeboat must point away from the structure when reaching the water.

The lifeboat is boarded with the davit in the stowed position. Re- lease and lowering are handled from the lifeboat by remote-con- trol wire operation. The hydraulic lowering cylinder is operated by the dead weight of the system, generating power for the revolving cylinder. The cylinder stroke is controlled automatically by an in- clinometer valve causing the davit to stop in a horizontal position.

The lowering of the lifeboat starts automatically before the outer frame is in position. At max- imum speed, double centrifugal brakes are activated, and smooth lowering is insured by a hydraulic winch. The lifeboat is released from the lowering from within the boat. Lowering may be stopped with the lifeboat in any position by release of the remote control wire.

The hydraulic winch with its double drums, planetary gears, and hydraulic motors adds consid- erably to safety of the Debarko

Safe system. For hoisting the life- boat, the hydraulic motors are dri- ven by a hydro-electric power pack.

LANE LIFEBOAT

Circle 43 on Reader Service Card

The origins of Lane Lifeboat go back more than a century, to 1863.

Over the years lifeboat construc- tion changed from wood to metal to fiberglass. Lane lifeboat, a divi- sion of Lane Marine Technology,

Inc., is a pioneer in the construc- tion of lifeboats of all fiberglass versus the metal and fiberglass combination.

In 1958 Lane built its first FRP lifeboat, which was placed aboard the USNS Patterson, an experi- mental gas-turbine-powered ship.

When the Patterson was taken out of service, the lifeboat was turned over to the schoolship John Brown to be used in the training of stu- dents in the proper handling of lifesaving gear. From the John

Brown it found its final resting place at the South Street Seaport

Museum in Lower Manhattan.

Lane currently has under con- struction one of the largest fiber- glass lifeboats ever built in the

U.S. It is a diesel-propelled boat 37 feet long with a beam of 12 feet 6 inches.

Lane maintains complete facili- ties in Brooklyn, N.Y., for the con- struction, repair, and reconstruc- tion of any lifeboat of fiberglass, steel, or wood. Boats are built and repaired according to the stand- ards and requirements of the U.S.

Coast Guard and Navy, the Amer- ican Bureau of Shipping, Lloyd's

Register of Shipping, and the mar- itime and naval arms of many for- eign governments. Customers in- clude most major oil companies and commercial cargo carriers.
