Respirators Memes

The evolution of lab safety protocols as depicted by expanding brain memes is painfully accurate. Starting with proper containment (glovebox), then progressing to ventilation systems (fume hood), followed by the outdoor respirator method favored by that one postdoc who's "being extra cautious." But the final stage? Pure chaos theory. The "wind will handle it" approach is what happens when you've inhaled just enough toluene over the years to believe you've transcended physical safety concerns. Safety officers everywhere are having simultaneous aneurysms.
