I’ve long been fascinated by the role of safety devices and greater risk taking.

Study after study has shown that if people normally act a “danger level of 2”, they’ll notch up their danger level to “danger level of 3” or “danger level of 3 1/2” if a safety device is designed to keep the device safe up to a “danger level of 4”.

This obviously undercuts many of the benefits of the safety device, when increased safety margins are just used to promote more dangerous behavior. Often redundancy encourages bad practices, even if it’s designed to increase safety. 

 … Do take a look at the Normal Accidents article I just posted.

I wonder if hospitals are seeing more patients suffering from arc blindness and severe skin burns from people using UV-C lamps to kill Coronavirus at home like this rechargeable one AliExpress. 

While UV-C bulbs (florescent lamps without phosphor) are very effective at killing bacteria and viruses and are widely used in hospitals HVAC and sanitizers, exposure to the light causes human skin to burn within seconds and causes painful arc flash and temporary blindness if you look into them like looking into a welder flash.

Today will be the safest Saint Patrick’s Day ever on the roads ever (usually the most deadly day of March). 🍀 Why?

  1. Tuesdays are always the safest day on the road
  2. Bars and restaurants that serve alcohol are closed
  3. Saint Patrick’s Day is a popular day to drink
  4. Traffic volumes are down significantly from an ordinary Tuesday, and even a few less cars on the road disproportionately reduces fatal crashes
