Mock drill compliance requires regular emergency preparedness checks, with different frequencies for plantations and other workplaces. Employers in factories, mines, construction work, industrial premises for the manufacture of beedi and cigar, motor transport undertakings, and dock work must ensure quarterly mock drills to test emergency preparedness for various emergencies. Employers in plantations must ensure annual mock drills for the same purpose. The rule creates a recurring safety obligation with different drill frequencies depending on the establishment.
