Safety is the state of being safe the condition of being protected against physical hazards. Unsafe

conditions threaten people’s health in all environments—in traffic, at home, on the job,

producing huge numbers of illnesses, injuries, and deaths. In most cases, these health problems could have been avoided if the victim or other people had

used reasonable safety precautions

Accidentsoccurs when a vehicle collides with another vehicle. A

number of factors contribute to the risk including vehicle design,speed of operation, road design, road

environment, driver skill and driver behavior. Worldwide, collisions lead to death and disability as

well as financial costs to both society and the individuals involved.

Government data reveal that accidental injury is:• The leading cause of death of

individuals under age 45.• Responsible for over 30% of all

deaths of children 1 to 14 years of age.

• The fifth most frequent cause of death in American population

Prevention and Causes of road accidents:

• SpeedingAround 400 people a year are killed in crashes in which someone exceeds the speed limit or drives too fast for the conditions.

• Disregarding of road signs and warning signs.

Drink DrivingAround 280 people die a year in crashes in

which someone was over the legal drink drive limit.

Careless or Distracted Driving:

Around 300 deaths a year involve someone being "careless, distracted or irresponsible driving.

Another approach addresses the role of cell phones in accidents: the risk of traffic mishaps is

four times as likely during or shortly after the driver uses a phone, even a hands-free phone.

Traffic injuries and deaths can also be prevented if drivers and passengers will use protective

equipment, such as seat belts in cars and helmets when riding motorcycles or bicycles.

Environmental Hazards:Environmental hazard' is the state of events which has the potential to threaten the surrounding natural environment and adversely affect people's health. Today we know that excessive exposure to the sun’ ultraviolet rays make the skin age and can cause skin cancers.Ultraviolet radiation is only one of many environs- mental hazards people need to guard against. Many harmful chemicals and gases exist in households, work- sites, and general communities.

Asbestos is a substance that was used in buildings and equipment as a fire

retardant. People who have regular contact with it risk developing lung cancer.

Lead poisoning, which can damage children’s nervous system and impair intelligence if they ingest it, such as by mouthing objects painted

with lead-based paints, or drinking acidic beverages from lead-glazed ceramics.

Radon, a radioactive odorless gas that can cause lung cancer with long-term

exposure, enters dwellings from the ground; ventilating a basement can reduce

radon pollution.

Radiation poisoning, which can occur with one very high- level

exposure or long-term lower exposure,

causes cancer. It can be released into the environment from

many sources, such as nuclear testing sites and power plants,

hospitals, and military facilities be done.
