In general, the rule is a bedroom must have an egress window, smoke detector and carbon monoxide detector if gas appliances are being used.  

There IS however carbon monoxide poisoning which can give someone all the symptoms of being in a haunted house --visual and auditory hallucinations, doing things and not remembering, etc. 

@John Carbone yes, it does.

@Caleb Heimsoth the business is in Intellectual Property for a system to convert natural gas and carbon biproducts into nano-materials such as graphene.

I do it every 6 months.Tell them it is to inspect smoke and carbon monoxide detectors.  

I typically have been mass mailing clients by blind carbon copying (BCC) an attached pdf document.I would love to find a software utility where I can not only personalize my emails to my clients by having their name in the "To:" versus "BCC:" but also avoiding attaching documents to the email but having photos and images embedded in the body of the email.I use a gmail account.

For the $40 to $50 price tag for a carbon monoxide detector, there is no reason to not have them.

I'd have sessions with the girls and taught them how to breathe through their nose while keeping a slight vacuum pressure in their mouth exchanging carbon dioxide, sometimes called making out or necking.

I do it to give me peace of mind and to try to prevent emergency services in the middle of the night.Well, sure enough, on the rental property we own with my in-laws the heating contractor was testing the carbon monoxide and it registered at 4,000 ppm.

My question is whether or not forms like a pet addendum, rental application, carbon monoxide/smoke detector acknowledgement etc. are state specific - I know the residential lease is subject to certain state regulations and will be asking an attorney about it.
