MacGregor's Propane Explosion Ruled Accidental, Fire Marshal Says

HAVRE DE GRACE, MD — A propane tank exploded outside a restaurant in Havre de Grace Friday afternoon, according to authorities. Several employees were injured in the incident, which happened in the outdoor grilling area behind MacGregor's.

Employees discovered the issue just before 2 p.m. Friday in the 300 block of St. John Street, the fire marshal said.

About 20 firefighters from the Susquehanna Hose Company arrived at the scene and brought the situation under control within two minutes, investigators reported.

Three employees suffered minor burns, and all refused to go to the hospital, Senior Deputy Fire Marshal Oliver Alkire told Havre de Grace Patch.

The estimated loss was about $100, according to the fire marshal.

Officials ruled the explosion accidental, stating it was caused by a loose fuel line connecting the fuel regulator.

"Employees at a Havre de Grace restaurant escaped with only minor injuries yesterday after their LPG tank caught fire," the fire marshal reported Saturday. "With more restaurants opening outdoor seating, owners and citizens are urged to use caution while grilling outdoors."

The fire marshal offered these tips for outdoor grilling safety:

• Before using it, check the gas tank hose for leaks. Apply a light soap and water solution to the hose. A propane leak will release bubbles. If your grill has a gas leak, by smell or the soapy bubble test, and there is no flame, turn off both the gas tank and the grill. If the leak stops, have a professional service the grill before using it again. If the leak does not stop, call the fire department.
• If you smell gas while cooking, get away from the grill immediately and call the fire department. Do not move the grill. If the flame goes out, turn the grill and gas off and wait at least five minutes before re-lighting it.
• Keep fire extinguishers on hand.
• If using a tent, ensure it is flame retardant rated.
