Lab coat versus concentrated acid

Want a visual for why you should wear a lab coat? Check out Pictures from an Organic Chemistry Laboratory, where Kristof has a photo from a nitration that went awry, spilling concentrated sulfuric and nitric acid “everywhere.” It might even be an argument for adding an apron over a lab coat in some...

Lab-safe, professional shoes for women

A query from chemistry reddit: Good lab shoes? I’m about to enter the corporate world but was having trouble finding women’s shoes both safe and professional. Do you know of any good brands or styles? I’d prefer low or no heel. Sanita or Dansko (closed-back) clogs are the main suggestions given. Anyone have other...

A radiation dosimeter to go on your hands

I’ve seen radiation badges before, but never a ring. Courtesy of the International Atomic Energy Agency‘s Facebook page: This type of ring is a small badge that workers wear under gloves to monitor external exposure to ‪#‎radiation‬ as they work with different types of radioactive sources. The little diamond shape on the ring is worn facing the palm, as this is the area where highest exposure usually occurs. This ring is...

Gloves for handling pyrophoric reagents

For readers who handle pyrophoric reagents, how do you balance hand dexterity vs protection? I’ve heard either nitrile under Nomex (in the form of Blackhawk Aviator gloves) or Nomex under neoprene. Other suggestions?

Consequences of poor glove choice

Via C&EN’s Chemistry in Pictures, shown here is what happened when “dichloromethane carried 3,4-ethylenedioxypyrrole through a researcher’s nitrile gloves. The compound polymerized onto the person’s fingers, forming poly-3,4-ethylenedioxypyrrole, a blue-black conductive polymer of unknown toxicity.” Check a glove compatibility chart before you experiment! The photo was taken by Kristof Hegedüs of...

Removing gloves and other protective equipment

One of the things highlighted in the news this week is the risks of contamination from removing—”doffing”—personal protective equipment. “Meticulous removal, or doffing, of PPE is as important as its meticulous donning,” wrote infectious disease physician Amesh A. Adalja in “Ebola Lessons We Need To Learn From Dallas.” Most chemists don’t need to fear Ebola, but they do wear PPE to protect from chemical exposure. I asked...
