An explosion and flash fire occurred at the Aspen Aerogels manufacturing facility in East Providence, Rhode Island on Wednesday night, injuring 11 employees who were taken to the hospital and later released. East Providence's fire chief said it's a 'miracle' no one was severely hurt, as the force of the blast was strong enough to send metal throughout the building and blow out walls. The state fire marshal is investigating the cause, which the mayor believes was likely due to a malfunction in a large industrial oven used in the insulation production process.

Why it matters

This incident raises concerns about workplace safety and the potential risks associated with specialized industrial equipment, especially in facilities that handle flammable or explosive materials. It also highlights the importance of thorough safety protocols and regular equipment maintenance to prevent such incidents from occurring.

The details

According to officials, the explosion happened around 8 p.m. on Wednesday at the Aspen Aerogels facility, which manufactures flexible insulation blankets and insulation for electric vehicles. Eleven employees were brought to the hospital for evaluation of possible internal injuries caused by the shockwave, but were all released overnight. The East Providence fire chief said the building sustained significant damage, with the 60-foot-long oven used to dry and cure the insulation materials being completely destroyed. OSHA had previously cited Aspen Aerogels three years ago for violations related to combustible dust accumulation and failure to provide proper respiratory protection for workers.
