If the fire alarm goes off at work what should you do immediately after evacuating the building?

After evacuating the building due to the fire alarm, you should proceed to the designated assembly point and ensure that everyone is accounted for. Avoid re-entering the building until emergency services have declared it safe. Follow any instructions from emergency personnel, and do not use your phone or other devices unless necessary, as they may hinder emergency communications. Stay calm and provide assistance to others if needed.
