July 24- This morning the Seattle Fire Department continues to ventilate the milk processing facility where a 4-inch 150-foot long ammonia gas pipe broke on Monday morning.
Four Seattle Firefighters continue to monitor EPA remote sensing equipment which checks the levels of ammonia gas inside and outside the building located in the 4000 block of Rainier Avenue South.
Throughout the night, Seattle Firefighters monitored gas levels and used a large-scale fan called a Mobile Ventilation Unit(MVU)to air out the building which contained dangerous levels of ammonia gas.
This morning the levels of ammonia gas dropped to just 20 parts per million and the air readings outside the door of the plant were zero parts per million. The MVU will continue to operate until 6 p.m. tonight when the scene will be turned over to the property owner.
This morning the operators of the milk processing plant decided to reopen their facility to workers.
