What necessary/safety precautions could you take in case of a suicide bomb attack?

well! in the literal sense of the question asked.. there is nothing much one can do if it has happened, its a blink of an eye event. if you say what should be done to prevent oneself from it BEFORE it has happened, then thats another question, something which i have no idea about coz the variables are so many and the chances of you getting hit by one is so low that it seems impractical to constrain one's movements because of it... but thats how i see it...

as far as the scenario of what to do after it has happened in the vicinity, an immediate idea that comes to mind is that no matter what, not to go in the direction of blast, coz there has been cases in which the initial blast is done just to lure people in for a secondary one. and number 2, get the heck outa there because chances are it might be followed by some live fire.. its the kind of situation where lightning does strike the same place twice.

stay safe! :)

Here's a somewhat related TedxLahore Talk by Dr. Zeeshan Usmani: http://www.youtube.com/watch?v=rLng7tBXa1U

I just googled "safety precaution for bomb attacks" there is hardly any search came up from a Pakistani website/blog or I guess jawab was the only one there. This is something very important and we need to make more awareness about it.

Something worth I found:
-Strictly implement the inspection procedures of all bags, knapsacks, boxes, merchandise, etc., that will enter the establishment or premises.
-Suspicious looking package, paper bags, etc. left alone should be cautiously scrutinized as possible bomb(s).
-When suspicious stuff are noted, don’t try to touch or inspect it. Instead, advice security personnel/employees to immediately contact the proper authorities.
-Be observant of people roaming around your area doing nothing. Vendors with tricycles/knapsacks/bags should be driven out, as they may be used as couriers of bombs.
-Advice the security to always observe people leaving behind bags/packages/boxes in the garbage cans/bins in the premises.
-Be observant of cars/motorcycle riding individuals who are suspiciously observing constantly the establishments.
-Be cautious in opening envelopes and packages sent to you by unknown individual or package with no return addresses.
-The greatest safeguard against the effects of bomb threats is to prevent entry of unauthorized persons into certain areas, whenever possible.
-Restricted entry and positive identification of staff and visitors can be significant factors in assessing the seriousness of any given threat.
-Develop a security plan and a bomb incident plan in preparation for such incident. The security plan deals with prevention and control of access to the building. The bomb incident plan provides detailed procedures to be implemented when a bomb is found or threatened.
-Get the involvement of the nearest police department, fire department, or local government agencies for any assistance in developing your security or bomb incident plans.

Whenever you leave your home or office, read 'Ayat Ul kursi'. Your journey will always be safe!

Tell everyone not to go to that place and if you are there than run away.

The only precaution u can take in a country like Pakistan to avoid a suicide attack is to not go beyond the parameters of your premises. Because you never know the guy sitting next to you in a public transport might just turn out to be one himself.

Just stay away from any kind of mob these days. If someone attacks, get down and keep yourself as low as possible.

stay more in public places where there are more people around and always keep an eye around if you see anything suspicious and also spend more time in your house than outside
