	We are having some Blast Resistant structures, with no access to the Terrace. I am of the opinion to provide MS ladder (Monkey Type) for the access to the roof of these buildings... 1) I want to know as if there are some repurcussions in doing that (By providing the ladder outside) ?? 2) Will it affect the Blast resistant nature of the Building, 3) Will it affect the structural integrity of the system and 4) lastly how it will behave in case of any eventuality or any blast ??? 5) Is it advisable to carry out such changes, when we know that the access to the roof will be required only once in a blue moon !!! Thanx and Regards Sailesh Kaw

	Where are you located? Local building code will call out exactly what you should do. Check the codes, and you will find your answer. __________________ Don't believe everything you read on the Internet!

	The only person who can answer this is the engineer who designed the structures. Make sure you don't void any warranties. __________________ In a time of universal deceit, telling the truth is a revolutionary act. George Orwell

	A lot of this depends on the nature of 'blast'. 1) a repercussion may be ease of unauthorised access to the roof. 2) anything attached to a surface will either enhance or detract. 3) see 2 4) how you design it to. see 2, 3. 5) see 1, 2, 4 One would need a drawing of the structure, including the structures superficial detailing + probability of blast position/orientation with respect to the structure + range of energies, inc. type of explosive, fragmentation mass estimates and distances, to answer any more fully. __________________ There is no sin except stupidity.

	I assume you are from Kashmir and that is blast prone area. Ladder you are planning to provide may be only 10' in height. I do not think such ladder will affect in any manner to main structure of building. __________________ "Engineers should not look for jobs but should create jobs for others" by Dr.Radhakrishnan Ex President of India during my college graduation day
