- cargo pump-rooms should be mechanically ventilated and the capacity should be 20 air changes per hour of the total volume of the pump-room.
- the position of the vent outlet should be arranged at a distance of at least 3 m measured horizontally from any ignition source and from the nearest opening to accommodation, service or machinery spaces.
- an emergency intake located about 2 m above the pump-room lower grating is to be provided. This emergency intake is to be used when the lower intake is sealed off due to flooding in the bilges. The emergency intake should have a damper fitted which is capable of being closed from the exposed main deck and lower grating level.
- floor gratings should not disturb the free flow of air.
- the fan blade should be non sparking type.
- A fixed gas detection system capable of continuously monitoring for the presence of hydrocarbon gas. Where such equipment is fitted, procedures should be developed to ensure it is regularly inspected and calibrated. Procedures should also be developed with regard to the action to be taken in the event of an alarm occurring, especially for vacating the space and stopping the cargo pumps. Whenever practicable, gas detection should monitor a number of levels within the pumproom, not just the lower area.
- A fixed sampling arrangement to enable the oxygen content within the pumproom to be monitored from the deck by portable meter prior to pumproom entry. Where such an arrangement is fitted it should ensure that remote parts of the pumproom can be monitored.
- Temperature monitoring devices fitted to the main cargo pumps in order to provide remote indication of the temperature of pump casings, bearings and bulkhead seals. Where such equipment is fitted, procedures should be developed with regard to the action to be taken in the event of an alarm occurring.
- A high level alarm in pumproom bilges which activates audible and visual alarms in the cargo control room, engine room and the navigating bridge.
- Manually activated trips for the main cargo pumps provided at the lower pumproom level and at the top (maindeck) level.
- Spray arrestors around the glands of all rotary cargo pumps in order to reduce the formation of mists in the event of minor leakage from the gland.
- Examining the feasibility of fitting a double seal arrangement to contain any leakage from the primary seal and to activate a remote alarm to indicate that leakage has occurred. However, the impact of any retrofit on the integrity of the pump will need to be clearly assessed in conjunction with the pump manufacturers.
- Particular attention to be given to the adequacy of fire protection in the immediate vicinity of the cargo pumps.
- Because of the problems associated with flashback re-ignition after the use of the primary fire-fighting medium, consideration to be given to the need to provide a backup system, such as high expansion foam or water drenching, to supplement the existing system.
- On ships fitted with an inert gas system, the provision of an emergency facility for inerting the pumproom could be an option, although careful attention must be paid to the safety and integrity of the arrangement.
- The provision of Emergency Escape Breathing Devices (EEBDs) located within the pumproom and sited to be readily accessible.
- Fire extinguisher of foam type must be present at the bottom platform of the cargo pump room.
- dead man alarm must be fitted in pump room.
- a neil robertson stretcher to be present on bottom platform of cargo pump room.
- ODMCS
- Intrinsically safe fire detectors are installed in pump room for detection of fire in pump room.
