2 of 3 gas canisters detonated in Sylmar; 210 Freeway open for now
Officials carried out a planned detonation of tanks full of volatile gas at an energy plant in in Sylmar on Sunday morning, but will have to conduct a second explosion because one of the three tanks was not breached, EPA spokeswoman Nahal Mogharabi said.
A portion of the 210 Freeway closed during the first detonation has been reopened, but will close again for the second attempt, which is expected to take place around 9 a.m. she said.
Federal environmental officials detonated the tanks of highly volatile tylar gas, a mixture of oxygen and hydrogen, at an alternative-energy business in the 12300 block of Gladstone Avenue. A robot then checked the scene.
Authorities removed a total of 23 canisters of pressurized chemicals and gases from the building after an Aug. 9 explosion that left Timothy B. Larson critically injured. A similar explosion occurred at a Simi Valley plant last year. Both plants were owned by Larson's father, Timothy A. Larson. Tyson Larson, 28, the brother of Timothy B. Larson, was killed in the Simi Valley explosion. The family-owned business is the subject of investigations by Cal-OSHA and the Environmental Protection Agency.
The 210 Freeway was closed between Maclay Avenue and the 118 Freeway. A parallel section of Foothill Boulevard was also closed.
