CLINTON, Md. — Four people were taken to the hospital after a household deck collapsed in Clinton, Maryland Thursday afternoon.
Members of the Prince George's County Fire Department responded to a report of the deck collapse in the 600 block of Kirby Road in Clinton just before 2 p.m.
At the scene, first responders noticed the deck in the backyard had detached from the side of the house on the second story and collapsed.
Four adults were taken by ambulance to an area hospital following the incident with non-life-threatening injuries.
Authorities have not yet said what led to the deck to detach and collapse.

As more people are gearing up to host summer cookouts, Donald Masters, who owns Master Home and Building Inspections, said it's most important to look underneath the deck to inspect the structure.
“As a doctor, I used to have said to me one time, you’re going to die of your weakest point. Same with your deck," Masters said. "You want to make sure that the weakest point on your deck is not something that’s a major failure point.”
If you need to focus on three key points to inspect, he suggests the following:
- Check for rust underneath. He said if you see that on the surface, it is probably worse inside.
- See if the deck moves while you're standing on it. That could mean structural instability.
- Make sure the point where the deck connects to the house is secure.
“The posts will rot out right where it meets the ground because that’s where you have water and oxygen and microbial growth," Masters said. "So if you see rot right at the surface, we know things are going on.”
He said to look for some type of flashing or sealing where the deck boards meet the house.
"What we’re trying to do is stop the rainwater from getting in between the two pieces of wood and sitting there and creating rot and debris gets in there," Masters said. "So if you keep the water moving out and away from the house, that protects what’s called the ledger board.”
He also suggests making sure the drain extends beyond the deck posts to make sure water build-up doesn't erode the foundation.
“Wood is just one of the things that nature would love to take back to soil in one way or another," Masters said.
On top of the deck, he suggested making sure the width of the gap between the balusters are no bigger than 4 3/8 inches so infants can't slip through.
Masters also said it's important to make sure weight is evenly distributed between different supports, so one post isn't bearing significantly more than another.
He said decks need TLC, so if yours is at least 10 years old, he suggested inspecting it every year.
