About SilentShadow.org

SilentShadow.org publishes practical, evidence-based education about carbon monoxide (CO) risks and prevention. Our goal is to help people recognize common exposure scenarios, understand what authoritative guidance says, and take safer next steps.

Who This Site Is For

This site is for the general public: homeowners, renters, travelers, and anyone who wants clearer CO safety information. We focus on real-world safety questions: alarms, common sources, warning patterns, and what to do when exposure is suspected.

What We Are (and What We Are Not)

  • We are an educational safety resource. On safety questions we summarize and link to authoritative guidance; on the state law pages we read the statute or adopted code ourselves and cite the section.
  • We are not a substitute for emergency services. If you suspect an active CO hazard, move to fresh air and call your local emergency number or fire department.
  • We do not provide personalized medical advice or diagnoses. For health concerns, seek professional care.

How We Create Content

We prioritize primary sources such as public health agencies, consumer safety regulators, national health services, building and fire safety organizations, and major medical reference resources. We write in plain language and include Sources sections on key pages so readers can verify information directly.

For more detail, see our Editorial Policy.

The state law pages are written by the SilentShadow editorial team. Nobody here is a lawyer, and the pages are not written as legal advice or as an opinion about anyone's position. What they are is a reading of the source, done the way a careful reader would do it and then published with the working shown: the statute or code section the answer turns on, the edition of the model code the state adopted, the date somebody opened the document, and the route that opened it when the obvious one refused.

That is why every legal claim on this site is attached to a citation instead of to a byline. You are not asked to trust our judgment about what a code says. You are given the section number so you can read it and disagree, and a page that cannot show you the text says so rather than filling the gap. Where a national table and our reading disagree, both citations are on the page.

For anything that turns on your own circumstances, a lawyer in your jurisdiction is the right place to take it. See our Disclaimer.

Updates and Corrections

When guidance changes or we find an error, we revise the page and update the "Last updated" date. If you spot something that looks wrong or outdated, please contact us with the page URL and a supporting reference.
