How it happened • December 3-4, 1984: 40 tonnes of methyl iso-cyanate (MIC) released from Union Carbide plant at Bhopal • Accidental release caused by leakage of water into MIC storage tank • None of the safety systems worked • Safety standards and maintenance system ignored for months • Complete absence of community information and emergency procedures • Public alarm system operated after the gas had leaked for nearly four hours
Case Study: Tokyo Subway Sarin Attack • Incident was not recognized as nerve agent attack until approximately 3 hours after release. • 12 dead, 692 Actual Victims from exposure, total 5500 treated • Only 688 of the 5,500 victims were medically transported. The rest were transported by passers-by or went themselves. Over 400 vehicles responded • 4,500 persons approximately were “walking well” • Nearest Hospital saw 500 patients in the first hour. • Over 1000 units of atropine were available
Tokyo Subway Sarin Attack Mass decontamination was not performed. • 135 responders suffered effects of exposure. • 20% of the hospital workers suffered secondary exposure. • Over 50% of those involved remain effected today. • 37% requested financial aid from the government. • $2.6 M was spent on medical expenses in first year. • 10% of victims quit school or work. • Personal belongings were placed into bags and returned to victims who were told to burn them.
Management • Risk assessment • Disaster prevention and mitigation • Preparedness • Disaster risk management as part of rehabilitation • Raising awareness • Strengthening local disaster risk management capabilities
Emergency Planning and Response • Regular running of equipment & tests on facilities • Emergency Management Plans -on site - off site • On site drills once in 6 months • Off site drill with Dist.Administration once in a year • Mutual aid Agreements with Neighboring industries/District Fire Services. • Updating of plans
HAZARDOUS WASTES (APPLICABLE TO ALL INDUSTRIES PRODUCING HAZARDOUS WASTE) • Treatment of Hazardous Wastes • (I) Reduction at Source/reuse/Recycle • (II) Dilution of Hazardous Waste. • (III) Commercial Available Alternatives • Physical treatment • Chemical treatment • Biological treatment • Thermal treatment • Stabilization/solidification/ sorption
MEASURES TO BE TAKEN DURING THE EMERGENCY CONDITIONS • The plant authorities should immediately contact the local administrator in case hazard is likely to spread beyond the factory. • The concerned Police Officers along with civic officials should make arrangements for evacuation of the people from the vicinity to safe areas. • The plant authorities should extend all technical support in controlling the damage. • Most importantly, it is the responsibility of the industry management that the people do not get panicky. • After all the hazard is totally eliminated, people may be brought back to their respective places of working and living.
Management • Understanding the event of chemical disaster by • Detection systems • Identification of adverse/abnormal health symptoms like vomiting of blood, itching of eyes, itching of skin and burns on skin in humans • Unusual death of human and animals • Alerting the disaster management team to wear the protective gear. • Alerting the population to wear the protective gear. • Detecting and mapping the affected area of disaster by team as cold, warm and hot zones.
Simultaneous evacuation of affected people from hot/affected zone by rescue team with protective gear. • Simultaneous decontamination of affected area by disaster management team. • Evacuation of civilians to contamination free shelters and bunkers at the time of disaster. While shifting they should be provided with protective gear and should be decontaminated before entering the safe zone. • Exposed individuals shall be decontaminated and shifted to shelters after the examination by doctor. • Medical protection shall be provided to affected peoples.
DOs SOP Cordoning off of hundred meter Diameter Finding out the wind direction Clearing of the down wind side immediately at least up to 500 meters with a corridor of 50 meter width Detection, rescue and decontamination team to wear individual protective equipment Detection team to detect contaminants using detection equipments and identify the agents Detection team after detection to demarcate the area in to hot zone, warm zone and cold zone depending on concentration.
