Managing construction sites are difficult due to temporary work nature, changing work area, untrained workers, over time works etc., Most of the accidents occurred in construction activities like building structures, demolition, excavation, roof work, alteration, scaffolding, painting etc,. In typical construction works about 1500 people are killed in Britain and 25,000-30,000 more are seriously injured. The accident statistics represent not only serious human tragedies but also substantial economical losses due to accidents which cause damage to plant and equipment, loss of productive time, loss of morale among workers, increased compensation and loss of image and reputation for the industry. The key to a successful construction project is to identify vulnerable hazards and eliminate or minimize them. To avoid accidents, the causes of accidents and reliability of the statistics are to be analyzed. Various construction regulations should be followed. The safety policy should be framed. Workers are to be trained in safe methods of work. Safe physical conditions should be provided in the construction sites. Sufficient and suitable personal protective equipments be provided and insisted. Supervision of work area are to be ensured.
