Question 1

NFPA 211 requires a minimum clearance of how many inches between a factory-built fireplace chimney and combustible framing?

Accepted Answer

1 inch

Question 4

Which respiratory hazard is most commonly associated with cleaning older masonry chimneys that served coal-burning appliances?
