BERLIN, Conn. >> As the weather warms and activities move outside, Eversource is encouraging residents to take precautions to ensure any Mylar balloons used to liven up the festivities won’t pose a threat to the electric system.

“It only takes one balloon to create a potential hazard for customers,” said Bob Coates, vice president of safety at Eversource.

In recognition of National Electrical Safety Month, Eversource is reminding customers that Mylar balloons can cause power outages and even pose a significant safety risk.

“The silver metallic coating on Mylar balloons is a conductor of electricity. If the balloon makes contact with power lines, it can damage electric lines and equipment, and cause power outages.

“In some cases it could even cause an electrical surge impacting nearby homes,” Coates said.

“Thousands of our customers experience outages each year as a result of Mylar balloons,” said Coates.

Customers can follow these safety tips:

• Make sure balloons are secured; tie them to a weight so they can’t fly away.

• Never release a Mylar balloon outside.

• Keep all balloons away from power lines.

• Never use metallic ribbon with Mylar balloons.

• Never tie Mylar balloons to yourself or a child.

• Always deflate Mylar balloons completely and dispose of them properly.

• Never try to retrieve a balloon that is tangled in electric lines; instead, call Eversource at 800-286-2000 to report the problem.
