Monitors Description

The Monitor is a device that delivers a large foam or water stream and normally is mounted on a stationary support that either is elevated or is at grade. The monitor can be fed solution by permanent piping or hose.

Common aplications

Refineries
Tank farm Railroad lines Fuelling Areas Helipads Aircraft Hangars Docks
Lumber Mills
Coal Storage
Chemical Processes
Exposure Protection
Paper Mills
Dust Abatement
Satellite Facilities
Fixed Roof Tanks
Floating Roof Seal Tank Indoor Storage Tanks Petroleum or Chemical tanker Track loading rack
Note: Monitors shall not be used as the primary means in some of this applications because of the difficulty of directing foam into a precise location.

Design criteria for monitor protection system

Monitor nozzle system design shall be based on the total ground area. The intent of the design shall be to protect the canopy, pumps, vehicles, and miscellaneous equipment.
In determining actual solution flow requirements, consideration shall be given to potential foam losses from wind and other factors, especially where foam monitors are used as the primary protection.
Normally the monitor shall be located outside the area that must be protected to prevent the damage of the unit, the distance from the monitor to the farthest extremity of the protected area forward of the monitor shall be not more that 75 percent of the monitor throws in still air conditions.Around the monitor installation shall be consider enough free space for easy movements of the unit, the access way must be directly accessible and free of any obstacle.
If the monitor is installed on a platform shall be permit 360 degree access around it. An elevated platform will allow to have a free throw from obstacles and therefore better performance.
Isolation valves shall be provided in the water, foam concentrate, and foam solution mains (immediately forward of any monitor position) to isolate damaged sections. In addition, each monitor shall have an isolation valve. Each valve shall be easily accessible. If the monitor has a flow rate over 3785 L/min (1000 gpms), it will be offered with a handle to use with two hands or with a hand wheel for every movements so that to prevent unwanted movement due to reaction forces. To avoid this risk, the lever monitor is predisposed for being locked into position while operating at full flow.
Sometimes, the fires happen in areas where the risk of anticipated fire doesn’t normally justify the expense for a fireproof plant type fixed, in this situation a portable unit can be a good and economic solution. Sabo Española can supply different types of portable monitors with or without the foam proportioning device.
The proper choice of each monitor location is a very important factor to consider during the planning of a foam monitor system. The homogeneous distribution of the throw, possible obstructions, wind conditions, and effective foam nozzle characteristics can influence the quality of the project. The appropriate monitors and nozzles should be located so that foam is applied to the entire protected area at the required application rate. Sabo Española is at your disposition to help to individualize the most suitable models for your purpose pointing out the optimal parameters to get its maximum performance.
Generally, the portable monitors are suitable to fight spill fires in diked areas. In order to obtain maximum flexibility due to the uncertainty of location and the extent of a possible spillage of liquids in process areas and tank farms, portable or trailer-mounted monitors are more practical than fixed foam systems in covering the area involved. The procedure to fight the fires located in the diked area is to extinguish and secure one area and then move on to extinguish the next section within the dike. This technique should be continued until the complete dike area has been extinguished.
Sabo Española can furnish different types of monitors to cover every type of installation. The most economic models and of great use they will be used manually through the lever or the hand wheels, self oscillating, electrical or hydraulically operated monitor are also available to realize complex fire fighting system applications. Sabo Española also produces a vast range of unit and accessories been born for satisfying particular demands, as for example special adapter to connect monitor to every type of hydrant , but in these pages are not brought for matters of space. We recommend you therefore, to contact us to verify the availability of the product that could resolve your problem.
Every monitor of the Sabo Española is designed to delivery a specific flow with a maximum pressure loss of 1 bar (14.5 psi), nevertheless actual flow rate is dependant on nozzle choice.
