Padma Multipurpose Bridge Project

Annex 8-3Traffic Accidents (Road & Rail):The most common emergency event the ERC will have to deal with will be road traffic accidents. Theresponse procedures will be the same for dealing with accidents on the approach roads and bridge.The lower deck of the bridge has a rail line and Railway accidents are of great concern due to theconstrained space and limited room for evacuation on the lower deck.Spill/leak of Hazardous Materials in Land & Water:Petrochemicals and other industrial chemicals are often transported by railway or freight, thus there isalways a concern of leakage or spill due to an accident, hazardous materials may leak/spill on land orinto the river. Another concern with Hazardous material emergencies is that accidents may be difficultto contain and may quickly spread over a large area and threaten entire communities.Civil Disturbance/Riot:Unauthorized protest marches and assemblies have the potential to affect the safe operation of thebridge. As well, this can lead to other emergency events such as traffic accidents.Terrorist Event/Threat:A Terrorist attack is always a real and credible danger especially for high level infrastructure targetslike bridges, gas lines and railways.Gas Leak/Explosion:A high pressure gas main is to be carried by the bridge on the lower deck. Although the risk of a gasleak or explosion is low, it is important to address it and develop procedures due to the potentialcatastrophic nature of such an emergency event.The response procedures, probability and evacuation plan for each type of emergency event is givenin Table A8.2-7. Also, the lead agencies as well as other coordinating agencies are given for eachspecific emergency event.Padma Multipurpose Bridge Design ProjectFinal Report (Environmental Action Plan)Environmental Impact Assessment Report A8-44June 7, 2010
