Road Traffic Accidents(RTA)
 90% of all RTA deaths occurs in low,middle income countries
 Causes of RTA
1.Pedestrians and animals sharing common road
2.Fast and slow moving vehicles
3.Old,poorly maintained vehicles
4.Low driving standards
5.Overloaded vehicles
6.Disobey of traffic rules
7.Defective roads,speed breakers,poor street lighting
8.Unusual behaviour of men and animals
Prevention and control of RTA/RTI
1.Education regarding safety
“If accident is a disease,education is its vaccine”
2.Promotion of safety measures
Seat belts
Safety helmets
Children on back seats
Parking at a suitable place
Low beam headlights
Avoidance of mobile phones
Door locks
Proper vehicle design
Avoidance of alcohol and drugs
3.Elimination of causative factors
o Marking of danger points
o Improvement of road conditions
o Imposition of speed limit
4.Enforcement of laws
o Medical fitness of driver
o Alcohol conc. In blood (80 mg/100 ml limit in India)
o Driving test
o Seat belt wearing
o Speed limit
o Helmets
o Vehicle inspection
o Periodic examination of drivers
5.Emergency care services
o Planning,organization and management of trauma treatment
and emergency care services
o Emergency care at the point of accident
Domestic Accidents
1.Drowning
• Most common cause of accidental deaths in Bangladesh and Maldives
• 98000 lives lost (SEAR,2002)
Prevention and control of drowning
Availability of life jackets and flotation devices around pools & boats
Supervision of children by adults
Fencing of lakes and ponds
Creation of safety standards for public and private swimming pools
Ensuring availability of weather reports to fishermen and
to those working on rivers and seas
2.Fire/Burn
 184,000 deaths (SEAR,2002)
 SEAR accounts for >50% of all fire related mortality
 Risk factors




Cooking on open fire
Explosion of pressure stoves
Instability of small stoves
Use of open fires in winter
Use of inflammable materials in house
Use of fire crackers
 Prevention and control of burns




Stable stoves/lamps
Replacement of pressure stoves with wick and gas stoves

 Agents: pesticides,kerosene,prescription drugs,
household chemicals
 Prevention and control of poisoning






Restricting availability of hazardous pesticides
Promotion of alternative non-chemical methods of pest control
Safe packaging of pesticides,insecticides and other chemicals
Dying kerosene blue and treating it with bittering agents
Selling therapeutic drugs in child resistant containers
Educating medical practitioners,health workers and community
on effective antidotes to poisons common in community
4.Falls
Responsible for largest number of hospital visits for non-fatal injuries
Prevention and control of falls
1.Safer playground(Use of mud & sand surfaces instead of paved ones)
2.Safer furniture & house designs
