Problems for SAR Teams Assess the magnitude of the calamities. Collect information both official & non official agencies for relief works. Ascertain resources available for relief ops.
Problems for SAR Teams..... Coordination of various agencies for : – Evolving a common programme of work. – Drawing up operations plans – Providing facilities like training of volunteers. – Establish liaison between Central & State Governments, Local authorities & Social Welfare Organisiations.
PRECAUTIONS & SAFETY RULES
CAUSES OF DAMAGE TO HUMAN LIFE Falling bricks/stones & plaster Splintering glass Toppling furniture, collapsing walls Rock and land slides on mountains Fallen power lines Sea waves generated Fires Panicky human actions
SIMPLE PRECAUTIONS Open area is safer Move away from falling debris, chimneys, over head tanks Rushing out through staircase is dangerous Switch off the lights, power supply & gas connection
SIMPLE PRECAUTIONS Move away from glassed windows & doors Stand behind an inside doorway Crouch under a desk, table or bench Don’t stay inside large unsupported halls
SAFETY RULES-BEFORE Predict the hazards Place large/heavy objects on ground Avoid stocks of glass & crystal ware on top Anchor overhead lighting fixtures Construct earthquake resistant buildings and follow building codes Know your local ER/CD set-up
Remain calm, Plan actions & consequences, Rescue others If indoors watch for falling objects/debris Stay away from glass windows, mirrors, chimneys SAFETY RULES-DURING
Get under a table, desk or bed in a corner Do not run outside If outside move to open area, avoid high buildings, power poles If in vehicle, stop in safe place in open area SAFETY RULES-DURING….
Check for injured persons Check for fires Wear shoes in all areas Check utility lines & appliances for damage Do not use matches,lighters, switches if any gas leak SAFETY RULES-AFTER
Do not eat/drink anything from open Do not spread rumours Assist CD & HG, Fire service, Police Do not crowd in to damaged areas SAFETY RULES-AFTER…
