LONGVIEW, Wash — A shelter in place has been lifted for residents in Longview after a fire at a company that houses water treatment products for pools and water tanks. The fire started around 9 p.m. at HASA, Inc.,  3400 Industrial Way. 

Fire officials asked residents in a two-mile radius to stay indoors, keep doors and windows closed. Cowlitz County Department of Emergency Management says the primary concern was sodium hypochlorite which can cause respiratory issues when it becomes vaporized under fire conditions. 

They said as of 1:30 a.m. sodium hypochlorite, a bleaching agent, was not detected by air monitors. 

The company's website stated they are a "leading producer and distributor of high quality water treatment products used to sanitize and maintain water systems, including swimming pools and water tanks."
