Background Information
There is little you can do to prepare for an explosion, but some of the preparation you can do for general disasters can also be applied to unexpected explosions. You can familiarize yourself with your evacuation plan for your area. You can also become familiar with the locations of extinguishers, fire exits, and the alarm system in your area. Fire extinguishers come in several varieties, and you can take courses in the proper use of each type. You can also take courses in first aid or CPR to prepare for the possibility of helping people with injuries.
If an explosion occurs, remain calm. Bear in mind that many things will probably happen at the same time. There may be further explosions; people may be injured and need help; smoke may be seeping in around a door.
In general, do not use cell phones or any electrical device that might spark further explosions. Signal for help by shouting periodically or by hanging an article of clothing out a window. If you are able to evacuate and are instructed to do so, do not use elevators, and be careful of fallen debris or of glass or heavy objects that might be ready to fall.
Action Steps
If an explosion occurs in your work area or building:
- Remain calm.
- If ordered, evacuate.
- DO NOT MOVE SERIOUSLY INJURED PERSONS unless danger is immediate.
- Assist persons whose injuries are not serious.
- Avoid windows, mirrors, furnishings that might fall, and electrical equipment. Watch for falling objects.
- Open doors carefully.
- Do not use elevators.
- Assist and accompany persons with disabilities.
- Do not use phones, matches, or lighters.
If trapped in a building:
- DO NOT USE CELL PHONES. They can trigger explosions.
- IF A DOOR IS WARM, DO NOT OPEN IT.
- IF SMOKE IS ENTERING AROUND DOORS, stuff clothing in cracks to block smoke.
- Signal rescue crews by placing clothing outside window, if possible.
- If there is no window, stay near the floor where the air may be less toxic.
- Shout periodically to alert rescue crews.
