  • testing and inspection of diving cylinders

    fitting of valves should follow the procedures specified in iso 13341 transportable gas cylinders - fitting of valves to gas cylinders. after the tests have been satisfactorily completed, a cylinder passing the test will be marked accordingly. stamp marking will include the registered mark of the inspection facility and the date of testing .

  • buoyancy compensator diving

    a buoyancy compensator, also called a buoyancy control device, bc, bcd, stabilizer, stabilisor, stab jacket, wing or ablj depending on design, is a piece of diving equipment with an inflatable bladder which is worn by divers to establish neutral buoyancy underwater and positive buoyancy on the surface, when needed. the buoyancy is controlled by adjusting the volume of air in the bladder.

  • seismic retrofit

    in the past, seismic retrofit was primarily applied to achieve public safety, with engineering solutions limited by economic and political considerations. however, with the development of performance-based earthquake engineering pbee , several levels of performance objectives are gradually recognised: public safety only. the goal is to protect .

  • halcyon rb80

    the halcyon rb80 is a non-depth-compensated passive addition semi-closed circuit rebreather of similar external dimensions to a standard al80 scuba cylinder 11-litre, 207-bar aluminium cylinder, 185 mm diameter and about 660 mm long . it was originally developed by reinhard buchaly rb in 1996 for the cave exploration dives conducted by the european karst plain project ekpp .

  • defoamer

    the easiest is looking at the surface foam. all that is needed is a system for generating foam. this might be done with a round pumping system with a nozzle and a cylinder or an air injection system into a cylinder. the cylinder is fitted with a scale to measure the foam height. this equipment may have a heater to control the temperature.

  • scuba manifold

    a scuba manifold is used to connect two diving cylinders containing breathing gas, providing a greater amount of gas for longer dive times or deeper dives.an isolation manifold allows the connection between the cylinders to be closed in the case of a leak from one of the cylinders or its valve or regulator, conserving the gas in the other cylinder.

  • diving cylinder

    a diving cylinder, scuba tank or diving tank is a gas cylinder used to store and transport the high pressure breathing gas required by a scuba set.it may also be used for surface-supplied diving or as decompression gas or an emergency gas supply for surface supplied diving or scuba. cylinders provide gas to the diver through the demand valve of a diving regulator or the breathing loop of a .

  • acetylene

    acetylene systematic name: ethyne is the chemical compound with the formula c 2 h 2.it is a hydrocarbon and the simplest alkyne. this colorless gas is widely used as a fuel and a chemical building block. it is unstable in its pure form and thus is usually handled as a solution. pure acetylene is odorless, but commercial grades usually have a marked odor due to impurities.

  • snuba

    instead of coming from tanks strapped to the diver's back, air is supplied from long hoses connected to compressed air cylinders contained in a specially designed flotation device at the surface. snuba often serves as a form of introductory diving, in the presence of a professionally trained guide, but requires no scuba certification.

  • decompression equipment

    there are several categories of decompression equipment used to help divers decompress, which is the process required to allow divers to return to the surface safely after spending time underwater at higher pressures.. decompression obligation for a given dive profile must be calculated and monitored to ensure that the risk of decompression sickness is controlled.

  • dave shaw diver

    david john shaw 20 july 1954 – 8 january 2005 was an australian scuba diver, technical diver, and airline pilot for cathay pacific, flying the lockheed l-1011 tristar, then the 747-400, and then the a330-300, a340-300, and a340-600. he flew for cathay pacific from 1989 until his death in 2005. before flying for cathay pacific he flew for missionary aviation fellowship in papua new guinea .

  • robert sténuit

    robert pierre andré sténuit born 1933 in brussels is a belgian journalist, writer, and underwater archeologist.in 1962 he spent 24 hours on the floor of the mediterranean sea in the submersible 'link cylinder' developed by edwin link, thus becoming the world's first aquanaut.

  • buoyancy

    buoyancy / ˈ b ɔɪ ə n s i, ˈ b uː j ə n s i / or upthrust, is an upward force exerted by a fluid that opposes the weight of an immersed object. in a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. thus the pressure at the bottom of a column of fluid is greater than at the top of the column.

  • isolation tank

    an isolation tank, often referred to as a sensory deprivation tank also known as float tank, float pod, float cabin, flotation tank, or sensory attenuation tank is a pitch-black, light-proof, soundproof environment heated to the same temperature as the skin.flotation tanks are widely advertised as a form of alternative medicine, but beneficial health effects are unproven.

  • relaxation technique

    a technique growing in popularity is flotation therapy, which is the use of a float tank in which a solution of epsom salt is kept at skin temperature to provide effortless floating. research in usa and sweden has demonstrated a powerful and profound relaxation after twenty minutes.

  • lockout–tagout

    lock out, tag out loto , lock out, tag out, try out lototo or lock and tag is a safety procedure used in industry and research settings to ensure that dangerous machines are properly shut off and not able to be started up again prior to the completion of maintenance or repair work. it requires that hazardous energy sources be 'isolated and rendered inoperative' before work is started on the .

  • gas cylinder

    a gas cylinder or tank is a pressure vessel for storage and containment of gases at above atmospheric pressure.high-pressure gas cylinders are also called bottles.inside the cylinder the stored contents may be in a state of compressed gas, vapor over liquid, supercritical fluid, or dissolved in a substrate material, depending on the physical characteristics of the contents.
