UPDATE: Two people were confirmed dead of carbon monoxide poisoning at a recording studio in a more-than-100-year-old former Passaic textile mill this afternoon.
Twelve people were hospitalized following the incident at the three-story Streets Rehearsal studio on Willet Street behind the Food Basics on Van Houten Avenue.
The two who died apparently were together on the second floor, while other victims were scattered throughout some of Streets’ 19 rooms, authorities said.
A host of emergency responders included Moonachie First Aid & Rescue, Lyndhurst Rescue and various fire and police departments.
The quick response after a 911 caller around 1:30 said that people were choking and disoriented prevented even greater casualties, Mayor Alex Blanco told reporters outside the building.
“It’s a sad day for the city of Passaic,” he said.
Initial concentration estimates ran between 1,000 and 1,200 parts per million — more than five times the amount considered life-threatening. At those levels, anyone exposed can lose consciousness after an hour and die in less than two.
At 100 ppm , a headache can occur after two hours exposure.
200 ppm: Dizziness, naseau, fagitue, headache after 2-3 hours of exposure.
400 ppm: Headache, nausea after 1-2 hours of exposure. Life threatening in 3 hours.
800 ppm: Headache, nausea, dizziness after 45 minutes; collapse and loss of consciousness after 1 hour of exposure. Death within 2-3 hours.
OSHA permits exposure to no more than 50 parts per million (ppm) in a workplace.
Streets Rehearsal “has a well established reputation for being the serious musician’s choice for rehearsal space and continues to build on this legacy today by offering the freedom and security that all musicians desire,” its website says.
Established in 1994. it offers 15-foot ceilings and rooms between 300 and 400 square feet, with heat, AC and electricity to musicians of various stripes — from rock to hardcore to prog to hip-hop.
Among Streets’ better-known alumni: My Chemical Romance.
The red-brick building dates to 1908.
