The chemical would then be put into sealed trucks and taken away for disposal.<\/p>\n<blockquote>\n<p>The non-toxic event in Garden Grove frustrates, inspires<\/p>\n<\/blockquote>\n<p><iframe class=\"wp-embedded-content\" data-secret=\"Vom1kGJP3O\" frameborder=\"0\" height=\"282\" loading=\"lazy\" marginheight=\"0\" marginwidth=\"0\" sandbox=\"allow-scripts\" scrolling=\"no\" security=\"restricted\" src=\"https:\/\/www.ocregister.com\/2026\/06\/02\/the-non-toxic-event-in-garden-grove-frustrates-inspires\/embed\/#?secret=Vom1kGJP3O\" title=\"\u201cThe non-toxic event in Garden Grove frustrates, inspires\u201d \u2014 Orange County Register\" width=\"500\"><\/iframe><\/p>\n<p>Residents may notice a \u201cdistinctive fruity or plastic-like odor\u201d during the process, officials said.<\/p>\n<p>\u201cThe product has a very low odor threshold, meaning people may notice a scent even when concentrations are well below levels associated with health concerns,\u201d the healthcare agency said. \u201cAir monitoring continues at the facility perimeter and in the surrounding community to ensure public safety and guide response actions.\u201d<\/p>\n<p>Methyl methacrylate is a flammable substance that generates heat spontaneously. Orange County firefighters responded to GKN Aerospace, at 12122 Western Ave., on May 21 after the company called and reported its system to cool the tanks had failed and that one of the tanks, which contained 7,000 gallons of the chemical, was in trouble.<\/p>\n<div>\n<\/div>\n<p>Orange County Fire Authority officials worked with the company and other experts to come up with a solution while using an unmanned ground hose to spray water on the tank to hold down the temperature. Officials at the time said there were two options: The tank would experience a thermal event known as a \u201cboiling liquid expanding vapor explosion,\u201d or BLEVE, or a crack would form in the tank, which could lead to a chemical spill.<\/p>\n<p>Read more <a href=\"https:\/\/siliconvalleymovingpost.com\/?p=11815\">The White House as a stage: Trump\u2019s hosting streak meets America\u2019s 250th birthday and the World Cup<\/a><\/p>\n<p>The crack did form, leading to a pressure release that allowed firefighters to regulate the temperature and neutralize the chemical.
