Psychological factors:
Inexperience,aggresiveness,defective judgement,
Alcoholism,drugs,stress
Road Traffic Accidents(RTA)
90% of all RTA deaths occurs in low,middle income countries
Causes of RTA

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
Installation of fire and smoke alrama
Promotion of cold water for first aid and burns
3.Poisoning
95,000 death(SEAR,2002)
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
3.Use of grills on windows
4.Safer design of stairs,balconies and rooftops with railings and bars
5.Safer working techniques for construction workers
5.Injuries from sharp objects
6.Animal bites
Industrial accidents
200,000 deaths per year in SEAR
Risk factors
Physical(Heat)
Chemical(Pesticides)
Biological(Animal bites)
4 “M”s
Mechanical Injuries(Thressure)
Manual labour
Man machine interaction
Mental condition
Prevention and control of industrial accidents
Ensuring the cost effective protection measures
Enforcing safety regulations and standards
Creating awareness among workers
Intentional Injuries
1.6 million deaths(Globally-2002)
390,000 deaths in SEAR
66% suicides in 15-34 years age group

• Suitable environment
Risk factors
• Violence as a means to solve the problem
