Indoor Gas Leaks: Ventilate

The IC should coordinate with a LG&E and KU representative before ventilating a building. Remember to look for solar panels and battery backup appliances. Exercise extreme caution when ventilating a building with natural gas concentration above 15% gas. As the gas dissipates and the concentration decreases, the amount of gas in the air will drop toward the flammable range between 5% gas and 15% gas. Remove all possible ignition sources before proceeding with ventilation.

When it is determined that ventilation is safe, ventilate the building from the top down, using natural air currents.

Artificial or forced ventilation is not usually necessary. However, if power ventilation is needed to clear the structure, use intrinsically safe ventilators and positive pressure ventilation on the upwind side. Be careful not to exhaust the gas into adjacent structures.
