Prepare a portable generator without creating carbon-monoxide risk
A generator can provide emergency power, but indoor or near-opening operation can cause fatal carbon-monoxide poisoning.
When it usually needs attention

What to do
Keep the exact manual, plan a dry outdoor location far from openings, confirm fuel storage rules, and arrange approved electrical connection equipment before an outage.
Applies when: Applies only to a confirmed portable generator.
