Overheated nitrocellulose ignited to set off Tianjin explosion

Chinese officials released on Feb. 5 a report into a 2015 explosion at a hazardous materials warehouse in Tianjin that killed 165 people. C&EN’s Jean-François Tremblay reports: The immediate cause of the accident was the spontaneous ignition of overly dry nitrocellulose stored in a container that overheated, according to the report, issued on Feb. 5. Wetting agents inside the container had evaporated in the summer heat, investigators found. Flames from that initial fire reached nearby ammonium nitrate fertilizer, which exploded. … Investigators found that Tianjin Ruihai International Logistics, the operator of the warehouse, illegally stored hazardous materials and that its “safety management procedures were inept.” It also assigned varying degrees of blame to 74 government officials from agencies at the municipal, provincial, and national levels. Some officials, investigators found, were guilty of “taking bribes and abusing power.” To prevent a similar catastrophe, investigators issued a list of recommendations, including the creation of a national system for monitoring hazardous chemicals storage. They also recommended that firefighters be better equipped. First responders accounted for 110 of the...

Culture of compliance versus culture of safety

Quote fom a New York Times story about the collapse of a construction waste dump in China that killed at least 69 people. How many U.S. workplaces does it also describe? “It’s quite often that the goal is to get approval, rather than be truly in compliance with the spirit, whether it’s the environmental impact assessment or safety,” said Dali L. Yang, a professor at the University of Chicago who has studied China’s efforts to strengthen safety regulation. “They think, ‘I can get away with this, so why bother?’...

CSB approves final report on West Fertilizer explosion

The U.S. Chemical Safety & Hazard Investigation Board (CSB) on Jan. 28 approved its final report on the 2013 ammonium nitrate fertilizer explosion in West, Texas, that killed fifteen people and injured hundreds of others. CSB found that key factors that led to the severity of the accident were: Poor hazard awareness Proximity of the facility to nearby homes and businesses Inadequate emergency planning Limited regulatory oversight Here’s CSB’s video about the incident: CSB issued a total of 19 recommendations relating to the explosion, to the Environmental Protection Agency, Occupational Safety & Health Administration, International Code Council (responsible for the International Fire Code), Federal Emergency Management Agency, Texas Commission on Fire Protection, State Firefighters’ and Fire Marshals’ Association of Texas, Texas A&M Engineering Extension Services, Texas Department of Insurance, West Volunteer Fire Department, and El Dorado Chemical...

Comparing safety culture in industry to academia

Comparing safety culture in industry to academia

Chemjobber had a guest post last week by Alex Goldberg, who started working as a pharmaceutical process chemist six months ago. He says, in part: And we have regular meetings about safety: we discuss near-misses and incidents and accidents (and we learn about the differences between them in safety training) that occurred in the previous month. And absolutely everyone wears his or her labcoat and safety glasses. Reflecting back on my academic training, I think about what universities can do to make safety an ongoing conversation, not just an onboarding exercise or an annual seminar. If we take long-hours and limited resources as a given in academic Chemistry departments — a topic which merits another discussion entirely — what can be done to build a culture of safety around those constraints? What does your lab and department do to accomplish this goal? Examples,...
