Enemalta will be testing the emergency alarms at the Delimara power station on Tuesday.

The alarms will sound at 9am and will last for less than a minute, the company said.

Testing the alarm is part of an annual procedure to ascertain the company’s readiness for emergencies at the power plant.

"The sounding of emergency alarms is one of the safety measures used to alert these communities in such situations," the company said.

Enemalta said there was an ongoing process to safeguard the health and safety of neighbouring residents and workers, to minimise the risk of environmental impacts and to ensure the security of the country’s electricity generation and distribution infrastructure.
