How And Where To Place Your Windsock

Windsock field placement is critical to workplace safety!

How To Position Your Wind Tracker Windsock

Wind Tracker Windsock System™ is field tested.

Windsock placement chart
When considering your windsock location the differences between a “Visual Only” location and, the “Actual Wind Action” occurrence is very important. Evacuation lanes, and their routes must be taken into consideration. Improper placement could lead to an unsafe evacuation of personnel to a safe assembly area.

The diagram demonstrates the need to understand correct placement of the wind monitoring sock.

Low wind pattern

Erratic low wind speed (At or near grade)

Variable wind pattern

Variable wind pattern 10 to 20 feet above grade)

Unobstructed wind pattern.

Unobstructed wind pattern (Top of or above structures)

Wind Flow Computer Model

Wind flow at 25 miles per hour is reduced below 5 miles per hour at grade and around structures.

Windsocks in the wrong place:

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.

Wind direction, force, and speed:

Blue lines in image depict wind speed reduced around structures below 5 miles per hour. Wind direction and wind action at lower elevations can vary dramatically. Structures, landscaping, temporary impediments like parked cars, type of area paving, elevation, climate, and other conditions can affect the wind direction, speed, and movement. Along with this, many airborne agents are heavier than air or are prevented from rising due to weather conditions such as fog, which keeps them close to the ground.

Two major windsock field placement factors you should consider:

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.
