Voorbeeldzinnen

1. .2 A valve shall be fitted to serve each fire hose so that any fire hose may be removed while the fire pumps are at work.
2. .2 There shall be at least one fire hose for each of the hydrants required by paragraph .5.
3. .3 The maximum pressure at any hydrant shall not exceed that at which the effective control of a fire hose can be demonstrated.
4. The length of a fire hose should be restricted to not more than 20 metres on deck and in superstructures and to 15 metres in machinery spaces and on smaller ships respectively to 15 metres and 10 metres.
5. The number and position of the hydrants shall be such that at least one jet of water may reach any part of the ship using one single maximum length of hose as given for class B ships in paragraph .7.2. .5 Every ship shall be fitted with at least one fire hose for every hydrant fitted. .6 In ships with a periodically unattended machinery space or when only one person is required on watch, there shall be immediate water delivery from the fire main system at a suitable pressure, either by remote starting of one of the main fire pumps with remote starting from the navigating bridge and fire control station, if any, or permanent pressurisation of the fire main system by one of the main fire pumps. .7 The delivery valve of each fire pump shall be fitted with a non-return valve.
6. .2 at least one set of portable air-foam equipment consisting of an air-foam nozzle of an inductor type capable of being connected to the fire main by a fire hose, together with a portable tank containing at least 20 litres of foam-making liquid and one spare tank.
7. .4 Every ship shall be provided with a fire main having a diameter sufficient for the effective distribution of the maximum discharge given above. The number and position of the hydrants shall be such that at least one jet of water may reach any part of the ship using one single maximum length of hose as given for class B ships in paragraph .7.2.
8. In new class B, C and D ships constructed on or after 1 January 2003 in such case, the drainage system shall be sized to remove not less than 125 % of the combined capacity of both the water spraying system pumps and the required number of fire hose nozzles.
9. .6 Except for watertight doors, weathertight doors (semi-watertight doors), doors leading to the open deck and doors which need to be reasonably gastight all ‘A’ class doors located in stairways, public spaces and main vertical zone bulkheads in escape routes shall be equipped with a self-closing hose port of material, construction and fire resistance which is equivalent to the door into which it is fitted, and shall be a 150 mm square clear opening with the door closed and shall be inset into the lower edge of the door, opposite to the door hinges, or in the case of sliding doors, nearest the opening.
10. 0,2 N/mm2 .3 The maximum pressure at any hydrant shall not exceed that at which the effective control of a fire hose can be demonstrated. .5 Number and position of hydrants .1 The number and position of hydrants shall be such that at least two jets of water not emanating from the same hydrant, one of which shall be from a single length of hose, may reach any part of the ship normally accessible to the passengers or crew while the ship is being navigated and any part of any cargo space when empty, any ro-ro cargo space or any special category space in which latter case the two jets shall reach any part of such space, each from a single length of hose. Furthermore, such hydrants shall be positioned near the accesses to the protected spaces. .2 In the accommodation, service and machinery spaces the number and position of the hydrants shall be such that the requirements of paragraph .5.1 may be complied with when all watertight doors and all doors in main vertical zone bulkheads are closed.
