What are the immediate actions of the first responder against "Explosive Incident "?

Try to save resources as much as you can then inform concern person, avoid taking selfie or recording videos of the victims. This is the worst thing nowadays, all are taking pics or recording videos just to tell on the tv channel we reported first in the world, they are cruel people who do like this. Even if Camera is your profession, in this type of incidents you are first human, you have to help others. Rescue all the people then take your camera and record what ever you want to record.

Sorry If I hurt anyone.
