Chemicals, leaking gas and faulty boilers could be the cause of life-endangering explosions:
  1. Remain calm.
  2. Stay away from windows, mirrors, overhead fixtures, filing cabinets, bookcases, and electrical equipment.
  3. Be guided by emergency response personnel. If evacuation is ordered, proceed to one of the designated exits.
  4. Do not move seriously injured persons unless they are in obvious immediate danger (of fire, building collapse, etc.).
  5. Open doors carefully. Watch for falling objects.
  6. Do not use elevators.
  7. If requested, assist persons with disabilities who appear to need direction or assistance.
