An explosion shook the waters near Baltimore’s Key Bridge Monday evening but thankfully, it wasn’t the tragedy it could’ve been.

Baltimore City Fire officials say the blast broke out aboard a 751-foot bulk carrier packed with coal around 6:28 PM, just after leaving the dock. The massive ship — carrying 23 crew members — immediately drew an emergency response by both land and water. Officials say everyone onboard is safe and accounted for.

The aftermath looked intense as a huge black plume of smoke shot into the sky, hovering over the water, startling nearby residents. The Coast Guard says they’re investigating what caused the fire.
