  • In the laboratory/manufacturing world we use this thing called the heirarchy of hazards control. It defines the steps you should go through when trying to make a process safer. The heirarchy is Elimination - Substitution - engineering controls - administrative controls - ppe.

    What most safety campaigns focus on is the administrative controls, or the 2nd to last step. Slogans and driving laws and things that can easily be ignored. Here, Hoboken has applied engineering controls - physical barriers that separate the person from the hazard. I guess in this case it’s removing an obstructing barrier.













  • So this is actually my industry - Wastewater Based Epidemiology or WBE. It is very anonymous. There is no way to pick out one person’s identity from the waste stream. What we get is a about 100mL of blend from 24 hour’s worth of shit water passing into the treatment plant. A tiny treatment plant is processing 100,000 gallons per day, while a top 10 plant is processing > 100 Million gallons per day.
