Shelter-in-Place Advisory – Bergen

Published on June 17, 2026

Update (2:40pm): Shelter-in-Place Advisory – Bergen

Emergency officials advise that the shelter-in-place advisory remains in effect within a 1/2-mile radius of 15 Church Street in Bergen.

Residents and businesses outside of the 1/2-mile radius may resume normal travel, but should continue to avoid the area around 15 Church Street.

Emergency crews remain on scene.

What Residents Should Do

• Stay indoors until emergency officials say it is safe to leave.
• Close and lock all doors, including garage doors to the outside.
• Close and lock all windows. Doors and windows may seal better when locked.
• Turn off air conditioners, heating systems, exhaust fans and ventilation systems.
• If possible, switch air inlets to the closed position.
• Close fireplace dampers.
• Close as many interior doors as possible.
• Keep pets inside.
• Avoid using elevators, as they may draw outside air into the building.
• Avoid open spaces in the upper levels of buildings, as ammonia gas is lighter than air and may collect in these areas.

Additional Shelter-In-Place Instructions for Ammonia Releases

• Building superintendents should set ventilation systems to 100 percent recirculation so that no outside air is drawn into the structure. If this is not possible, ventilation systems should be turned off.
• Use tape and plastic food wrapping, wax paper or aluminum wrap to cover and seal bathroom exhaust fan grills, range vents, dryer vents and other openings to the outside, if possible.
• Seal any gaps around window air conditioners with tape and plastic sheeting, wax paper or aluminum wrap.
• If the ammonia smell starts to bother you, hold a wet cloth or handkerchief over your nose and mouth.
• For a higher degree of protection, go into a bathroom, close the door and turn on the shower in a strong spray to help “wash” the air.
• Seal any openings to the outside of the bathroom as best you can.

Do not worry about running out of air to breathe, as this is highly unlikely in an average home or building.
