Guide to evaluation of human exposure to vibration in buildings – Blast-induced vibration
| Published By | Publication Date | Number of Pages |
| BSI | 2008 | 24 |
This part of BS 6472 gives guidance on human exposure to blast-induced vibration in buildings. It is primarily applicable to blasting associated with mineral extraction. This part of BS 6472 might also be useful in assessing other forms of vibration that are caused by blasting, including when explosives are utilized in civil engineering works and in demolition activity. One-off explosive events such as bridge or building demolitions are outside the scope of this document.
This part of BS 6472 does not give guidance on the probability of equipment malfunction, building damage or injury to occupants in buildings subject to blast-induced vibration. Neither is guidance given on legal liability or vibration control and minimization. Advice on damage risk is given in BS 7385.
