Yep, just heats the pan to melt the sulfur. Once it melts it needs no heat. I only use it once a month or so. If you have problems I guess you could use it more. It's more of a back up if I think I see something that worries me.
That PM sucked, so I don't chance it. Lights off is when to use them. Then after a couple hrs of the vapor doing its thing you exhaust all air. Not too sure about running one in a room you are sleeping in. Your exhaust doesn't re-cycle into that room but vents into an attic, if I remember right, so it may be fine.
Maybe run it when no ones around then do a big exhaust.
It's kinda overkill IMHO. There are other ways to kill bugs or spores than one of these. The one you posted would be no different in this regard. Like 9:1 water/milk sprayed on the plants is very effective for the PM. As good as this and you mentioned a new baby around. May be something to research b/c I have no clue if an infant is more sensitive. The sulfur dissipates after some time but I don't remember the hours. You've talked about door locks and kid proofing I remember so I know you're paying attention to these things, just saying.
Maybe you can post what you find out so others can see how sulfur dissipates and works. Hope that helps.

Hi Dan, I found a small amount of info on another site here's a
Link :-
http://www.thcfarmer.com/forums/f57/vapor-sulphur-burner-toxic-17789/index2.html
And here's a
Link to a
'Health review' on Sulfur :-
http://www.epa.gov/air/sulfurdioxide/health.html
Here's what some of the people said :- Current scientific evidence links short-term exposures to
SO2, ranging from 5 minutes to 24 hours, with an array of
adverse respiratory effects including bronchoconstriction and increased asthma symptoms.
These effects are particularly important for asthmatics at elevated ventilation rates (e.g., while exercising or playing.)
Studies also show a connection between short-term exposure and increased visits to emergency departments and hospital admissions for respiratory illnesses,
particularly in at-risk populations including children, the elderly, and asthmatics.
EPA’s National Ambient Air Quality Standard for SO2 is designed to protect against exposure to the entire group of sulfur oxides (SOx).
SO2 is the component of greatest concern and is used as the indicator for the larger group of gaseous sulfur oxides (SOx). Other gaseous sulfur oxides (e.g. SO3) are found in the atmosphere at concentrations much lower than SO2.
Emissions that lead to high concentrations of SO2 generally also lead to the formation of other SOx.
Control measures that reduce SO2 can generally be expected to reduce people’s exposures to all gaseous SOx. This may have the important co-benefit of reducing the formation of fine sulfate particles, which pose
significant public health threats.
SOx can react with other compounds in the atmosphere to form small particles. These particles penetrate deeply into sensitive parts of the lungs and
can cause or worsen respiratory disease, such as emphysema and bronchitis, and can aggravate existing heart disease, leading to increased hospital admissions and premature death. EPA’s NAAQS for particulate matter (PM) are designed to provide protection against these health effects.

Apparentley if you run it only a few times in a 100% sealed room during dark periods and then get your in-line fan to expell it through a carbon filter and leave the windows in your house open for a couple of hours the Sulfur will leave fairly unnoticed, with a mere eggy smell'.
On the whole though its pretty dangerous to breath, and can really fuck you up lol... I think I'll find another method of pest control, especially since I have the kids in the house and my wife also
And eggy smells aren't cool lol
Thanks Dan for the info etc...Its something I can look back on and refer to at a later stage as and when my growroom location decides to change, Since I don't yet & fingers crossed wont have an infestation in my growroom I was looking into
precautions more than anything
I will look into the best methods of pest control though, cos lets face it no one like unwanted bugs, mites n critters in their prized grow space, And its always a good idea to be
one step ahead, I'll look into the main Pest's! That pollute grow spaces and I'll also look into the best methods of wiping them out (without fatal health risk's) for both Plant and Human
Hope this has helped people....Its defo. been an eye opener for me - STELTHY
never mind though the THC gain will be worth it
