As spring forage chopping is underway here in the mid-Atlantic, there is an increased risk of silo fires. While these fires are usually confined to the unloading chutes, remember that the fire may not be the only concern.
Freshly chopped forage will produce toxic gases. This is primarily nitrogen dioxide this time of year but can vary based on time of year and product.
This morning in western Berks County PA we encountered both fire and gas in a silo just filled with ryelage.
For farmers, please remember and respect the hazards and for more safety information please check out the International Silo Association.
For emergency responders, please be using appropriate PPE, including SCBA, and assure air monitoring is in place.
