Chapter 17 – Safety• Hygiene hazards can result from inadequate or poorly located drainagefacilities in galleys, heads and bathrooms.• Inadequate specification of the complement at the design stage of theplatform can lead, later in service, to beyond capacity use of heads,bathrooms and laundry facilities as the complement builds up. Thisconsequently results in an accumulation of fluid spillage and dirt in suchareas.• Use of ceramic tiling on work surfaces and decks in galleys results inabsorption of slop water and bacterial growth. This is exacerbated by thefrequency with which tiles are cracked and not replaced.HFI Technical Issues• Care should be taken in the selection of materials for the finishing andfurnishing of the platform to specify acceptable thresholds on propertiessuch as:oooooFlammability potential.Smoke and toxic gas production in a fire scenario.Heat release rate.Halogen content.Asbestos content.• The possibility of the leakage and venting of fuels from tanks intoaccommodation spaces and workplaces can occur because of the routingof associated pipe work through these spaces.• Air quality and space ventilation can be readily saturated by smoke fromfires.• Waste disposal procedures and equipment design should have thecapacity to cater for defined long periods between discharge withoutgenerating a health hazard.• Ladder design and hatchway positioning with poor illumination are allcontributors to accidents on board.17.1.3 Use of Computer EquipmentAn important class of health hazards has been associated with the use ofcomputer equipment. Recent Health and Safety Executive legislation hasdefined parameters for the design and use of visual display units and computerinput devices. The types of health hazard that this legislation addresses are verylikely to arise with the use of modern computer workstations, particularly due tothe prolonged length of time that operators must remain closed up while workingunder stressful conditions. Eyestrain and upper limb disorders are two of themost common health hazards that can be counteracted by implementing knowndesign standards and requiring relatively simple procedures.Nov 2006 Page 17-5 Issue 4
