What Not To Do Lab

What Not To Do Lab

During the first week of school, I welcome my students to the What Not To Do Lab. The PDF is available for free at the Laboratory Safety Institute website. I use the cartoon activity to review their Safety Contract handout from the night before (I use the one from FLINN Scientific). With more than 30 safety violations shown, the cartoon serves as a great ice breaker as I have each student introduce themselves and then list a safety infraction being shown on the cartoon.

Time required: 

This can be completed easily within a 50 min class period.

News from the UK

CLEAPSS is a subscription service, but our YouTube Channnel is an open source. The videos are designed for teachers and technicians in schools. They may just give you ideas. I have just put one up about electrostatics and the effect of magnets on water and oxygen. In a couple of weeks I hope to have a sequel showing the effect of magnets on precipitates and complexes.

Why do we have to do chemical equations and calculations?

Fe & Sulfur reaction

(A look at workplace exposure limits found in MSDS sheets)

There is useful information in section 8 of a (Material) Safety Data Sheet (MSDS) that teachers can use and shows how a knowledge of chemical equations and calculations helps protect the health of their students and themselves and helps to assure their employers and safety officers that teachers and lecturers are responsible and professional users of chemicals. 

Is the MSDS Sheet a useful document for a chemistry teacher?

Bob Worley | Tue, 11/25/2014 - 16:24

Whenever a serious incident takes place in a school chemistry laboratory or classroom, fire and safety officers often pontificate on the incident by quoting the Materials Safety Data Sheet (MSDS). However, how many of you have read such documents in full? In UK schools we have perhaps 200 to 400 chemicals on the shelves. Have you read the MSDSs for each chemical?

Cautious Chemist #2: Be Responsible

safety before excitement

I recently spoke by email with Bob Worley as he prepared an article, But Surely That’s Banned, sharing some thoughts on chemical safety for teachers from his UK perspective. Part of the discussion revolved around our shared concern for using methanol for demonstrations. The Fire Tornado demonstration, that was part of the September 2014 Nevada museum incident, can easily be found in written form and video in a quick Google search.

But Surely That's Banned

The Royal Society of Chemistry became increasingly frustrated in 2004 when academics (the “when I was a lad” variety”), National Tabloids (it’s “‘elf un safety gone mad” variety), and many teachers were quoting health & safety fears as the reasons not to do practical science work and demonstrations.

Cautious Chemistry Corner #2: Methyl Alcohol Again

Another chemistry demonstration accident has happened. This one was at a museum in Nevada. In preliminary reports, it looks as if several children were injured. One child was held overnight in the hospital. See the article posted on Yahoo News. (Thanks to Tom Kuntzleman for the link.)

The Cautious Chemist Corner: Safety in the Classroom and Laboratory

safety

Chemistry classroom accidents have been in the news too often recently. I hazard to suggest that there are smaller incidents that never make the news because there are luckily no serious injuries. We need to be vigilant in our safety concerns to protect our students and ourselves from any accidents and exposure to hazardous substances. We also need to be aware of theft concerns. Unfortunately, students may be looking for ingredients to experiment with explosives or to manufacture illicit drugs.
