How do you control jet reaction |
Position on stable ground Start with pressure and flowrate that can be coped with and increase as and when needed Have minimum 2 people when on high flow rate and pressure Hose run out in straight line behind branch branch operator |
|
|
Mercury ground monitor operating ranges |
Raises/lowers 30-60 degrees Side movement 20 degrees either side of centre Nozzle can be lowered to 20 degrees if an operator stays with the unit |
|
|
When should a ground monitor be used |
Larger volume of water/foam is required than can be provided by hand branches Operation require extinguishing media to be thrown a greater distance Operations require extinguishing media over long period of time in same area of operations |
