I'll keep that in mind next time I'm using my SpO2 meter.

You know, as a follow-on to the whole prior post all about signage, this current blog post includes two more signs, starting at about 12-point font. It makes me wonder if anyone there even reads signs. It is a workplace tradition to simply ignore signs, or deliberately go against whatever they say, if you happened to notice some words and you read them. I would get so uptight about following every sign to the letter, that it drove other people up the wall. Because where I was, the signs were placed passive-aggressively by an administrator without a handbook, who just seemed to add more and more rules as they went along.

Whereas it seems in the Antarctic station where this blogger works, reading and obeying signage may be a matter of life and death, safety of life and limb.
