Osha Memes

From mouth-pipetting concentrated sulfuric acid to panicking over a drop of dilute acetic acid on a glove - chemistry safety standards have come a LONG way! 😂 The 1950s chemist is literally using their mouth to suck up H 2 SO 4 (one of the strongest acids that can literally dissolve your face), while today's chemist is having a full-blown crisis over 0.001M acetic acid (basically slightly stronger vinegar) touching their protective gear. Fun fact: Mouth pipetting was actually a common lab practice until the 1970s! Scientists would literally taste unknown chemicals to identify them. And you thought YOUR job was stressful!

Nothing says "nutritious breakfast" like a chemical warfare agent used in WWI. The meme sarcastically recommends a daily dose of phosgene at the exact concentrations various countries deemed "maximum allowable" for workplace exposure. For context, phosgene smells like freshly cut hay right before it destroys your lungs. Finland apparently thinks you can handle 10x more than everyone else—clearly they breed their chemists differently over there. Pro tip: if your lab safety manual includes recommended daily intakes, you might be in the wrong cookbook.
