I would put down vapor barrier over it, then particle board.

All plywood and solid wood and no particle board, at a good price.

I told him to get a higher rated filter if he wants better filtration of the air, but I guess he doesn't understand that there are filters that filter smaller particles and will get dirty faster like a MERV 11, even though I told him 5 times, maybe he was just drunk (bar owner)...I'm still trying to figure out what the pet penalty for the cat should be, it is in the lease but it says that its up to the landlord to decide what the penalty should be.

I have purchased Home Depot in-stock cabinets and although the boxes are cheap particle board and the hinges and drawer glides are just ok, they have fared well with standard use.

If you are going with a euro or frameless type cabinet (think ikea) chances are they will be particle board core with melamine or laminate faces.

We unpack boxes to find out that although they look great the side panels are particle board with a laminate veneer over lay.

More than likely, i'll have our handymen go paint the area and re-trap any lead particles.  

Smoking also includes the use of an electronic smoking device which creates an aerosol or vapor, in any manner or in any form. [2] “Electronic Smoking Device” means any product containing or delivering nicotine or any other substance intended for human consumption that can be used by a person in any manner for the purpose of inhaling vapor or aerosol from the product.

Tenants want me to do an inspection to assess any carcinogenic particles in the property related to the fire.

The next and this may have changed due to improvements  but we had gas dryers and the ignitor glow bars would fry due to particles and lint attaching to the bar.
