Dear Abbe


Dear Abbe, We have many bottles of old or questionable chemicals in


our histology lab. Unfortunately it’s going to be costly to dis- pose of them. Any ideas on how to reduce our HazMat inven- tory inexpensively? Cheapskate in Chico

creative ways to dispose of waste material. Having expired or unstable chemicals around can be a pain, and it is even worse if they are acutely noxious. It’s less hazardous these days to dispose of an unstable/acutely noxious colleague than to dis- pose of old chemicals! As I have discussed in the past, there are chemical and biological hazardous and, more importantly, administrative hazards. Not long ago a neighboring chem- istry lab found some ancient picric acid squirreled away in a cabinet, called it in, and a bomb squad rushed to the lab to dispose of the horrible explosive. Tey had a nice break as the building was immediately evacuated. Tis was particularly effective since it disrupted a scheduled administrative meeting with them. Or use my method (if you don’t mind the risk of getting caught transporting hazardous materials). A colleague and I discovered several old, crusty cans of ether hidden in the back of a cabinet. A nice rind had formed around the cap of the metal cans, and I talked him into taking them to a fallow field several miles from town. He was a bit puzzled until I had us walk about 50 yards, kneel behind a berm, and insert some ear- plugs. I pulled out my trusty Mauser rifle and started plinking the cans. My, what fireworks! My friend did not seem amused. Donnerwetter! Looking for creative ways to escape meetings and interper-


sonal hazards? Aren’t comfortable handling explosive situations? Give Herr Abbe an opportunity to make it more dangerous! Con- tact him via his unstable assistant at johnshields59@gmail.com.
