What to Tell Responders

Wait for responders or other qualified professionals to confirm it is safe to return. NHS carbon monoxide poisoning guidance · SCDF emergency medical services
Prevent Exposure During a Power Outage
Keep portable generators, charcoal grills and fuel-burning camping stoves out of enclosed spaces. Generators also need to be kept away from windows, doors and vents.
