The Naval Physical and Oceanographic Laboratory (NPOL), Thrikkakara, observed the National Safety Day on Tuesday with talks and demonstrations.

The senior most technician of the lab hoisted the safety flag and administered the safety pledge. The fire and safety wing of the lab's security division conducted a firefighting demonstration.

Talk by officials from the Deputy Transport Commissioner's office made the day special. An inverter-supported emergency light system, conceived by the NPOL Safety Committee, was dedicated to the lab by its director S. Anantha Narayanan.
