Nine people were hurt between the two incidents, and now Montgomery County Fire and Rescue is warning homeowners to examine their decks to make sure they are structurally sound. “As you go up to the deck, or up the stairs, touching the handrail, does that handrail wobble, that means that your railing and the post that the railing is attached to is not fixed securely to the deck structure,” said department chief Scott Goldstein. There also shouldn’t be any feeling of sponginess while on the deck. If there is, Goldstein said, the deck boards need to be looked at.
