It's interesting, isn't it?  Most only seem note they are in place and push the button.   I believe it's probably due to a lawsuit and liability...especially here in California.  

I've never seen smoke spray used. Didn't even know it existed.

No not with smoke spray. I guess you can set the kitchen on fire to see if it 'really' works also. 

No.  But they must be certified good by the fire department who push the buttons,,,no smoke

Hmmm. you inspector has without thought, provided you a house warming/closing gift idea.

I have witnessed the inspector executing the battery test ONLY.

Hmmm, how do you suggest the carbon monoxide detector be tested. That one be a truly LETHAL can of spray.

I agree with Michael Jacobs - everything seems to be a liability these days but, you can purchase the spray cans yourself and test them every 6 months.

Placement and testing is all that they are required to do.  And, yes ,my inspetor does that.  If a owner wants to test it ... they can spray with smoke. Additionally, buy updated 10 year lithium battery type detectors and regularly spray with smoke. People need to be more responsible and accountable for their own safety.  I agree with Michael Jacobs - I can see someone suing because they are allergic to smoke!!!

There are some that do, but most do not use a spray. That is a great questions for them in the future

no.  they just push the button.

checking that it works, with the smoke spray, is just a moment-in-time.  there's no guarantee it will still work, 30-60 days later....

Exactly what Michael Jacobs said  After all we hold the distinction for most litigious state.  A

These things are more like a disposable appliance than a part of the real estate.  Have your buyer pull out a match and test it, replace if necessary.

Bic cigarette lighter.

No, I have never seen them use the smoke spray.

yes, they do.... always....

What Michael Jacobs said.

Not around here.

Only push the button. Never saw smoke spray.

Ii've never seen anyone test a detector with smoke spray.

Not with smoke spray never heard of it, but do push the button.

What an awesome question! I never seen one single home inspection report with any reference about smoke detectors. From now on, I'll pay attention to this - many thanks to you.

Yes I see them do it. They bring a ladder to be able to reach them.

I have not seen my inspector use smoke spray but I will pay closer attention to what he does at our next inspection. I was told that detectors should be replaced every 4 years. 

Thanks for the question. Never went any further than testing the button myself

I have compliants that smoke detectors go off suddenly. I suspect they are smoking weeds.

I've never heard of smoke spray!

No, our Home Inspectors do not test the smoke detectors Christine Kankowski North SD and Temecula.  And in some homes/rooms you could not get to them easily!  I have never seen a smoke spray.  I agree with many, that Michael Jacobs is correct!     

I don't know of inspectors that use a smoke spray to test.  -Kasey

No smoke spray or fire drills...if the light or the buzz goes on...I'm done here

I don't recall seeing an inspector test the button, let alone using a smoke spray to disrupt the beam.

Only for batteries; have not seen smoke spray tests.

No , they just push the button, but you have a good point.

Like Nina, no idea that smoke spray for testing detectors existed!

Usually they do.  However in some homes the very high ceilings make them difficult to reach.

Push button and check date of manufacture and date of last install.

Yes.

This is not a requirement; however, Sweet Brown wishes it were:

No.

Yes

My inspector does push the button, but not with smoke spray.  Will need to ask him about this.

they do

Lyn Sims nailed this one!

And CO detectors too!

Christine Kankowski North SD and Temecula - in MA, it is the responsibility of the sellers.

I would be looking for anew inspector.  Mine uses real smoke
