STAO Safety Mindedness Teacher Training Resource -Updated with Closed Captioning!!!

Closed Captioning Update

The STAO Safety Mindedness (SSM) program is an interactive online training program to train teachers on common safety-related issues in a typical Science (Grades 9–12) and Science and Technology (Grades K–8) programs. SSM is an easy to use, flexible and cost-effective strategy to meet your school’s safety training needs. The training provided by this program helps promote a culture of safety mindedness in your school. SSM has just been updated to include closed captioning.

Content 

Both the elementary and secondary versions of SSM are divided into 8 convenient modules.  The content of each module is consistent with STAO’s safety reference texts, ‘Safety in Elementary Science and Technology’ and ‘Safe On Science, Second Edition’.

Access

SSM is available, free of charge, to all teachers and can be accessed from the STAO website, blog, or via the following links.  School boards are encouraged to run SSM off their internal servers at no cost.  Contact info@stao.org for details.

School Board Customization Services Available.

SSM can be customized to include board-specific content, e.g., logos, inserts (customization charges will apply). Contact info@stao.org for details.

 

Sample Science Safety Contract from Flinn

Science is a hands-on laboratory class. You will be doing many laboratory activities that require the use of hazardous chemicals. Safety in the science classroom is the #1 priority for students, teachers and parents. To ensure a safe science classroom, a list of rules has been developed and provided to you in this student safety contract. These rules must be followed at all times. Two copies of the contract should be used. One copy should be signed by both the student and a parent or guardian and turned in before participating in the laboratory. The second copy should be kept in the student’s science notebook as a constant reminder of the safety rules.

Learning by Accident: Spotty Evidence!

Curriculum Connection: High-school Biology

I was preparing Sudan IV for a nutrient lab for grade 11 SBI3C biology. In order to use the chemical as an indicator for fats and oils, I needed to mix the Sudan IV powder with ethanol. I followed proper safety precautions (gloves, goggles, fume hood). Somehow, a small amount of the Sudan IV powder got on my hand. I promptly washed my hands with soap and water, and checked the MSDS which advised me to flush the exposed area with water. After flushing, my hand appeared to be clean. Continue reading

A Safer Alternative to the Rainbow Demonstration

While serious accidents causing catastrophic injury in high school science activities are rare, when they occur their human toll can be devastating.  This post examines one potentially dangerous demo, its hazards and suggestions for safer alternatives.

The Rainbow Flame Demonstration:

Several of the most serious science accidents have resulted from the combustion of flammable liquids in teacher demonstrations like the rainbow flame demonstration.  In this demo, metals salts are heated in a ceramic dish containing burning methanol.  The flame colour observed is characteristic of the metal.  Click on this link for an example of how this demo is sometimes done. Please note that the procedure used in this video, in our opinion, is unsafe, inappropriate for students of any age and NOT recommended for teachers.

The Hazard:

Methanol vapours are extremely flammable. Furthermore, since the density of methanol is greater than that or air, methanol vapour can flow invisibly across surfaces like the demonstration desk and onto the floor towards unsuspecting observers. A flame, spark or even a hot surface can supply sufficient energy to ignite the vapour and create a sudden flash fire. The situation can be even more catastrophic if a nearby open container of methanol is present.

The Safer (and Better) Way:
