Are there any safety concerns around using ClO2 gas near a pilot light?

Pilot Light Precaution: When gassing a room or house for odor removal, it is recommended to turn off pilot lights for safety. While chlorine dioxide gas is not explosive, a high concentration of gas near a pilot light can cause a sudden burst, or noise similar to a firecracker or small explosion. Turning of pilot lights is a precaution that will ensure a safe environment during the treatment process.
