Mary Beth's comments bring up two items:

1. The manager of an industrial research lab motivated a technician to
wear safety glasses by allowing her to purchase whatever color frames she
wanted to match her clothing. In the 70's this was interpreted as a
positive step. The technician once showed me a desk drawer with at least 50
pairs of safety glasses, from which she would color coordinate her PPE! I
still think this is a cool response to the human factors problem.

2. Way back when, the JT Baker Safety seminar series included the
egg/corrosive demo. We would set up a series of "Tupperware" trays with a
out of the shell egg in each. We would then add about 10 mL of HCl, HNO3,
H2SO4, 50% NaOH and 25% NH4OH to separate trays. During the demo, we would
use appropriate PPE, protect the participants, and discuss the immediate
damage. We would then demo the JTB spill products on the results. I still
use images of these demos on those rare occasions that I do a lab safety
demo. Sad to say that RCRA and liability concerns relegated this live demo
to video.

And, finally, I have started using "Unigoggles" to solve the extreme
discomfort of splash goggles.

The conversation on eye protection and standards makes me think about
a topic dealt with often in CSB investigations, that is "human
factors" or "human errors." I have seen human errors boiled down to
two types, intentional (I choose not to wear safety googles) or
unintentional (I do not know about splash protection). Human beings
don't usually think about the safety regulations that govern their
activities, so it becomes very important that the safety management
systems remove what motivates the intentional decisions their
employees are making or educate workers to help them understand the
unintentional decisions they are making.

What I really mean to do by this post is spark a conversation that
addressed the human factor of the problem, so, here are my thoughts on
intentional or unintentional decisions to were eye protection:

Intentional: I will say that in grad school the reason I often times
chose not to wear safety googles was because I wear prescription
glasses and the awkward, clunky plastic ones in the lab did not fit
well over my glasses, constantly fogged up, and cut into my face. If
comfortable googles had been available to me I think I would have worn
them (at least more often) while I grad school. Have others found that
comfortable eye wear has increased its usage?

Unintentional: After grad school I spent a year teaching high school
chemistry and I found a safety demonstration for what acid could do to
your eye. I don't remember what acid I used, but it was adding acid to
egg whites which essentially cooked the egg whites. I showed that to
my class and kids continued to reference the demonstration for the
rest of the year. It was the best motivator I had ever used to get
students to wear googles.

If in the circumstances he (representing his employer) believed that they
not a risk of eye injury, then splash goggle are not needed.

In the video, the announcer specifies that the eye injury is present. ...

Please forgive me for disagreeing with the lab safety guru, but in our
of the woods it is hard enough to get lab personnel to wear safety
let alone wear goggles. Here we require goggles when there is a
splash hazard but for light-to-moderate work in your typical research lab
require safety glasses with side shields.

Unlike Jim who feels the producers are "totally wrong", IMHO this video
help us increase the use of eye protection. Bravo and thank you UCSD!
