First up, our thoughts are with everyone in the Boston and West, Texas, areas today.
Secondly, on the fertilizer explosion in West: Although early reports all said that the incident involved anhydrous ammonia, C&EN’s Jeff Johnson reported yesterday that ammonium nitrate was likely the explosive material at West Fertilizer Co. Today, the Los Angeles Times and New York Times both say the facility had ammonium nitrate. The NYT gives numbers: “540,000 pounds of ammonium nitrate on the site and 110,000 pounds of anhydrous ammonia.” The current toll is 12 confirmed dead, 60 missing, more than 200 injured, and many left homeless. I’m curious whether zoning laws actually allowed that amount of hazardous material so close to a residential area, two schools, and a nursing home. For local coverage, see the Waco Tribune and Dallas Morning News.
Now on to other news from the past few weeks, skipping incidents and focusing other things that I’ve collected:
- Mark at Chemistry Blog posted about his grandfather’s chemical legacy:
A day later I had sorted everything out into three categories: Category 1, mostly harmless (salts, some buffers etc). Category 2, most definitely not harmless (concentrated acids and such like). And the third category I called “What the f*** has he got here!”
- In the Pipeline posted a video, “made at some point by some French lunatics,” that nicely illustrates the hazards of working with chlorine trifluoride
- A debate on whether chemistry demos overly rely on explosions emerged on Twitter; ChemistryWorld gathered the tweets at Storify while Philosophically Distrubed blogged that “chemistry explosions are all bang and no buck“
- It’s been a while since I’ve said this, but it’s worth a reminder: Students and postdocs, be aware that you may not be eligible for workers’ compensation if you’re injured in a lab (reminder courtesy of this story about injured student athletes being responsible for their health expenses)
- NOAA released updated Chemical Reactivity Worksheet software
- Accounts of Chemical Research published a special issue on Environmental Health & Safety Considerations for Nanotechnology
- As OSHA emphasizes safety, long-term health risks fester says the New York Times, in a piece that looks at exposure of furniture workers and n-propylbromide-containing glues
- The Pump Handle covered worker safety provisions in the Senate immigration reform bill
- The Defense Nuclear Facilities Safety Board says that the Hanford nuclear waste treatment plant “has design problems that could lead to chemical explosions, inadvertent nuclear reactions and mechanical breakdowns“
- The April issue of the AIChE’s Process Safety Beacon is out: Have you heard a pressure relief valve chatter?
- The National Academy of Sciences published a review of the Department of Labor’s Site Exposure Matrix Database, which DOL uses to determine compensation for occupational exposure claims at Department of Energy facilities
