Massive 11-alarm Passaic chemical plant fire has been contained, building collapsed

With the fear of a potential chemical explosion goading them on, several hundred firefighters battled soaring flames, frigid temperatures and iced equipment to knock down a massive fire at a site in Passaic packed with hazardous substances Friday and Saturday, helping avert a larger disaster.

While the flames engulfed about 100,000 pounds of chlorine in one building and an official put damages to the facilities of Majestic Industries and Qualco Inc. — which makes pool treatment supplies — at more than $15 million, firefighters managed to keep the inferno from spreading to an area where far larger amounts of chlorine and other materials were stored.

“This fire could have reached the main chemical plant and we could have been looking at a potential mass evacuation,” said Passaic Mayor Hector Lora, who called the firefighters’ all-night efforts “heroic.”

“They are the reason why this fire did not reach the main chemical plant where the highest concentration of chlorine is located,” Lora said.

Lora said he was particularly thankful because the COVID-19 pandemic would have made it difficult to house hundreds of evacuated residents. “Where would we take everybody?” Lora said. “Where could we appropriately accommodate them in the midst of the pandemic?”

Fulltime Passaic firefighters were joined by volunteer firefighters from dozens of surrounding communities to attack the 11-alarm blaze, which was initially called in as a car fire shortly after 8 p.m. Friday and eventually sent so much black smoke billowing into the air that it was detected on weather radar.

With the threat of the fire reaching the 3 million pounds of potentially hazardous substances stored daily at the site, firefighters raced to douse the flames even as the frigid overnight conditions froze hoses and hydrants and made walking on frozen ice treacherous.
