Windsocks in the wrong place:
Two major windsock field placement factors you should consider:
The average windsock is most commonly positioned at high elevations (at the top of a silo or large building) for everyone to see. Unfortunately the wind action is vastly different because it is unobstructed, and not affected by site conditions that would be in or around the evacuation lanes of personnel. During an emergency this could be fatal. We recommend ground level installation in and around the evacuation routes up to and at the muster areas. You can mount a unit atop a structure for general wind direction and inbound assistance (approaching fire equipment, ambulance, etc.) to the facility. Another factor is wear and tear at higher elevations. Because of unobstructed wind the velocity is higher, and therefore the windsock undergoes more stress. You will find that wear can be increased as much as 50% depending on placement. Remember, wind speed and direction are not always the same in both locations.
The first is line of sight, and the second is accuracy. Place one or more Wind Tracker Wind Systems where they can be seen from the ground from various locations throughout the facility. We recommend you first identify the lanes of evacuation, the assembly areas that will be used for evacuation and the line of sight associated with each of these. Place the Wind Tracker™ units in various locations and/or heights to assure line of sight, and accuracy of wind speed and direction.
