Using all entry and exit gates, staggered lunch breaks, adequate thermal scanners, and sanitisation of premises are some of the guidelines laid down by the Delhi Disaster Management Authority (DDMA) for reopening of schools and higher educational institutions. The DDMA has said the head of the institute has to ensure that all staffers are vaccinated. Thorough sanitisation should be carried out in libraries and college premises and there should be adequate availability of thermal scanners, hand sanitisers and soaps, it said.
