Important to discard hot ashes properly
One of the most common fires we respond to is a fire caused by hot ashes being placed in a box or bag and stored on the back deck. When you clean the ashes from your fireplace or wood burning stove, make sure to place them in a metal container with a tight fitting lid.
Place the container on a non-combustible surface like your concrete garage floor and leave them in the container for at least one week.
At that time they will be safe to discard in the trash.

I suggest that all vacation rentals have this posted in the house, if they haven’t already. Thank you
