New safety guidelines for chemical demonstrations released

The ACS Division of Chemical Education recently finalized new safety guidelines for chemical demonstrations, following a number of injuries from demo fires and other mishaps in the last several years. The guidelines build on similar efforts by the U.S. National Fire Protection Association and Chemical Safety & Hazard Investigation Board. The new guidelines seem straightforward and contain nothing surprising. Hopefully they’ll help prevent further injuries. You can download the guidelines here. For a graphical version of the similar National Fire Protection Guidelines, see...

Risk perception and communication in C&EN

Risk perception and communication in C&EN

Cognitive psychologist Baruch Fischhoff of Carnegie Mellon University writes about risk perception and communication in C&EN this week: Whether judging the risks of a chemical, a financial product, or a looming pandemic, when people lack facts, they must rely on their perceptions. As scientists, we addressed the big question of how those perceptions arise by employing the small-question tools of our field—studies designed to disentangle the complex processes shaping all behavior. Building on basic research into how people think, feel, and interact, our work revealed general patterns. Although the piece–and Fischhoff’s research–is geared toward how the general public might perceive risks raised by the chemical industry, it sounds like some of the work could be applied to improve communication of safety concerns to laboratory or manufacturing workers. Fischhoff includes some resources in the...

Poor storage of 2,4-dinitrophenylhydrazine leads to controlled explosions in the U.K.
Nov09

Poor storage of 2,4-dinitrophenylhydrazine leads to controlled explosions in the U.K.

At least 40 U.K. schools have called in bomb disposal teams to dispose of improperly stored 2,4-dinitrophenylhydrazine (2,4-DNPH or 2,4-DNP), Chemistry World reports. 2,4-DNPH is used in a practical exam for U.K. students to complete their “A-level” to complete high school. Students would react an aldehyde or ketone with 2,4-DNPH to produce a colored 2,4-dinitrophenylhydrazone. The experiment had been discontinued but was recently reintroduced. Some schools “have retrieved questionable 2,4-DNPH ‘from the dusty back shelves of the chemical store,’ ” Chemistry World says. If the material dries out, it becomes sensitive to friction and shock. Simply removing the container lid could result in an explosion. That’s why the disposal method of choice is a controlled detonation, as also often happens with dried picric acid. A U.K. advisory service for school science and technology programs, CLEAPSS, recommends that: The solid is supplied damp or ‘wetted’ to minimise the risk of dust/air explosion. Keep solid damp at all times. Stand the bottle of damp solid inside a larger container that also contains a little tap water in the bottom (~ 1 cm depth). Label both the inner and outer containers. If solid may have become dry, do NOT attempt to open the bottle. Contact CLEAPSS. Or, if you’re not in the U.K., probably whoever handles your hazardous waste...
