Safety hypocrisy

I was drinking my morning coffee and watching YouTube this morning when I came across this video by The Backyard Scientist.  For those of you who haven’t seen him, he’s a guy who does “scientific” things in his backyard, usually involving something destructive.  Highly entertaining, to say the least.

The video I mentioned above is titled “This Is Why You Need To Wear Safety Goggles” and shows a number of dangerous things involving power tools.  As with most of his videos, it’s fun to watch things get destroyed.  Unfortunately, during many of the demonstrations he doesn’t actually wear safety goggles at all.  Specifically, when he works with the impaling device/table saw and when he plays with the chainsaw/angle grinder.  Yep, you read that right:  A video that’s supposed to promote safety goggle use neglects to use safety goggles.

I’d like to say that this content creator is the only person who does this sort of thing, but I can’t.  In most of the chemistry classrooms I’ve visited, there are serious violations in eye-protection safety precautions.  It’s not uncommon for teachers to tell students to wear goggles and then do one or more of the following:

  • Fail to wear safety goggles, or wear them only when immediately in the presence of the lab equipment.
  • Fail to ensure that each of the students is wearing their safety goggles.
  • Fail to ensure that visitors to the classroom wear safety goggles.

One might argue that goggles aren’t always needed because eye-related injuries are extremely rare.  After all, we’ve all seen that safety goggles are typically damaged by being dropped rather than through accidents.  However, consider this:  It only takes one accident like this in your career to blind a child.  One instant of having a student fail to wear their goggles can lead to blindness.  Put like this, it’s clear how important it is to have everybody in the room wear their goggles.

The reason I focus so much on this, rather than on other topics, is that eye safety in a high school chemistry lab is the biggest concern we have.  Though it’s not uncommon for students to burn themselves or cut themselves on broken glass, these injuries are rarely serious enough to warrant even minor medical help.  Even in the very rare cases where medical help is necessary, a burn or cut won’t lead to the same life-altering injury that is caused by blindness.

The good news is that it’s very easy to practice good eye safety in the lab.  Just follow these steps:

  • Make sure everybody in the classroom wears goggles during lab experiments, whether or not they’re in proximity to the equipment.
  • Make sure everybody wears goggles until the last lab group has completed their lab.
  • Make sure all visitors to the classroom (this includes your administrator!) wear goggles during the lab.
  • You need to wear goggles during the lab to set an example.

To show the seriousness of this rule, the punishment for not wearing goggles should be a zero on the lab and removal from the classroom.  I know it sounds harsh, but there is nothing more important in a chemistry class than safety.  Though no credit on a lab can hurt a kid’s grade, an accident involving one’s eyes can cause permanent blindness.  As long as you make it abundantly clear that this rule is to be followed, it will quickly become a habit that your kids just automatically follow.

Enjoy the link to the video and The Backyard Scientist’s other videos – they’re interesting and fun to watch.  However, don’t be as casual when it comes to lab safety.
