Under the Factories Act 1948, an ambulance room must be provided and maintained in every factory employing more than:

• A 250 workers
• B 300 workers
• C 400 workers
• D 500 workers ✓

Explanation

An ambulance room is mandatory where more than 500 workers are employed. It must contain the prescribed equipment and be in the charge of a qualified nurse cum midwife, with a trained dresser available and transport arranged for injured or sick workers. The 250 worker threshold triggers the canteen requirement, and 150 triggers washing facilities and lockers, so these numbers are distractors.
