Failure occurs when the environment exceeds the limits of a design. Reliability goes down as an environment changes from the one that was anticipated by the designer to one that is more extreme.

Residential rooftops are one of the most dangerous workplaces in the United States. Recent rooftop solar mandates like the one in CA can have negative impacts on worker safety. However, there are options to mitigate these risks.

Here’s what I don’t really get: the question of what the clock says in relation to the sun and the question of what time schools and businesses open are completely separate. We need to sort of agree on Q1, but we can make local decisions on Q2.

People in Maine should perhaps have more daylight saving by shifting opening times more than people in Florida, but in either case it would be a shifting of local start times: changing school start time from 7:45 to 8:45 in winter, for example.

There are safely drawbacks to the changes, forward or backwards, and there are local weather and sunlight considerations to account for in deciding to change start times or not, but local jurisdictions can make those determinations. Just leave the clocks alone.

“Seeking to find a single cause for a crash is a fundamentally flawed approach to road safety, but it underpins much of American traffic enforcement and crash prevention,”

Risk compensation rarely erases all gains of new safety measures, but many keep assuming that it does, and we lose the trust of the public because of it.

The difference between the risk analyst’s idea of “acceptable risk” and the public’s is similar to the difference between a physicist’s idea of “work” and the colloquial meaning.

“Acceptable” in this case does not mean okay or good. It only means that temporarily, continued investment in risk mitigation may no longer be the top priority in comparison to other risks.

As other risks are mitigated, then a previously accepted risk, may once again, become unacceptable.
