The Sky is Full of Germs

They found a lot of different species up there blowing around in the wind, but “We know a lot about how much of an undesired bacteria can be in our food or water before it makes us sick,” Gernand says. In contrast “we very rarely have that kind of information for inhaled pathogens,”

You Will Definitely Feel Microwave Radiation

This is a pretty good summary of microwave oven hazards, but omits the biggest point: unlike x-rays that you cannot feel, you will definitely feel microwaves, and it will feel like part of you is on fire.

Is it safe to stand in front of a microwave while it’s on? Here’s what experts say. (yahoo.com)

Why We Don’t Tolerate Airline Safety Issues

This is a good example of how “dread” or the fear of an unusual hazard or risk outside of daily experience demands extra attention that we could, but choose not to devote to other hazards.

SpaceX Worker Safety

Organizations should know that being safe and mitigating risk is not contrary to meeting goals quickly or innovating, nor is it synonymous with being bureaucratic.

These are serious concerns reported here and hopefully SpaceX learns to see worker injuries as serious setbacks to schedules and major drains on human resources.

Fire! on the Tiangong Space Station!

COMMENT: New Texas Law Removing Water Breaks from Workers

Removing and not replacing local heat safety standards doesn’t reduce regulatory uncertainty, it just places new liability on individual businesses | New Texas law will get rid of water breaks for outdoor workers amid extreme heat – ABC News via https://abcnews.go.com/US/new-texas-law-nullify-local-ordinances-protecting-outdoor/story?id=100272286

Businesses must still comply with the “general duty clause” of the occupational safety and health act which requires employers to provide a workplace free from recognized hazards. OSHA rule making is needed here. That will reduce regulatory uncertainty.

Masks Work

An ineffective rollout is partly to blame for getting us into the current polarization on this issue, but effective masks are well-understood and a key part of mitigating exposures to all kinds of airborne contaminants.

CPSC to Regulate Gas Stoves

I mean, I have one… and I understand why people like to cook with them over the alternatives. But, burning anything indoors creates pollutants that can increase the risk of disease, especially in the vulnerable.

Rage Applying?

Not sure that I get why normal labor market behavior would be considered “rage applying”. People go where they are most valued.

Universal Time, Anyone?

I find these articles so frustrating… https://t.co/zg1PGcfilk

Yes, changing the time we get up by an hour (either way) out of pace with the sun has negative safety and health implications, but

  • The sun’s position relative to the clock is different depending on latitude and your relative longitude within your timezone; every area is affected differently.
  • The clock time by which we start work or school doesn’t have to be fixed. Every locality can change these as it makes sense.

So, let’s all do what is best for safety and health where we live, regardless of what the government says the time is.

Peer Review Needs Rethinking

Authors’ names have ‘astonishing’ influence on peer reviewers: https://t.co/42tMZ4Nv4O

Peer review as it is intentioned is a good and necessary part of science, but it isn’t usually executed that way. Single-blind peer review (where reviewers know the authors, but the authors don’t know the reviewers) really needs to end. Double-blind peer review and open, post-publication peer review are better models.

Infrastructure Failure and Climate Change

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.

NEW PAPER: Residential Rooftop Mandate in CA Has Worker Safety Implications

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.

Spring Forward (Again)

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.

All Causes Contribute to Safety Incidents

“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,”

Public Safety and Risk Compensation

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.

What is an acceptable risk?

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.
