Construction is the most dangerous land-based work sector in Europe, after the fishing industry. In the European Union, the fatal accident rate is nearly 13 workers per 100,000 as against 5 per 100,000 for the all sector average.</ref>[1]

In the U.S. there were 1,225 fatal occupational injuries in the construction sector in 2001 with an incidence rate of 13.3 per 100,000 employed workers.[2] For the same year the construction industry experienced 481,400 nonfatal injuries and illnesses at a rate of 7.9 per 100 full-time workers in the industry.[3] Construction has about 6% of U.S. workers, but 20% of the fatalities - the largest number of fatalities reported for any industry sector.[4] Hong Kong is also notorious for its high construction accidents rates. Although the accidents rate dropped from 350 per 1000 workers in mid 1980 to 60 per 1000 workers in 2007, it still accounted for nearly 20% of all the industrial accidents in Hong Kong.[5]

The problem is not that the hazards and risks are unknown, it is that they are very difficult to control in a constantly changing work environment.

Nature of hazards

Hazards to construction workers

Various workplace safety signs commonly used at construction sites and industrial work environments.

The leading safety hazards on site are falls from height, motor vehicle crashes, excavation accidents, electrocution, machines, and being struck by falling objects. Some of the main health hazards on site are asbestos, solvents, noise, and manual handling activities.

Falls from heights is the leading cause of injury in the construction industry. In the OSHA Handbook (29 CFR), fall protection is needed in areas and activities that include, but are not limited to: ramps, runways, and other walkways; excavations; hoist areas; holes; formwork; leading edge work; unprotected sides and edges; overhand bricklaying and related work; roofing; precast erection; wall openings; residential construction; and other walking/working surfaces.

The height limit where fall protection is required is not defined. It used to be 2 metres in the previous issue of Work at Height Regulations. It is any height that may result in injury from a fall. Protection is also required when the employee is at risk to falling onto dangerous equipment.

Fall protection can be provided by guardrail systems, safety net systems, personal fall arrest systems, positioning device systems, and warning line systems.

All employees should be trained to understand the proper way to use these systems and to identify hazards. The employee or employer will be responsible for providing fall protection systems and to ensure the use of these systems.

For further information and specifics, 29 CFR list out further instruction in Subpart M.

Motor Vehicle Crashes are another major safety hazard on construction sites. It is important to be safety cautious while operation motor vehicles or Equipment on the site. Motor vehicles shall have a service brake system, emergency brake system, and a parking brake system. All vehicles must be equipped with an audible warning system if the operator chooses to use it. Vehicles must have windows and doors, power windshield wipers, and have a clear view of site from the rear window.

Equipment on the job site must have light and reflectors if intended for night use. The glass in the cab of the equipment must be safety glass. The equipment must be used for their intended task at all times on the job site.

Further instruction can be found in 29 CFR Subpart O.

Before any excavation has taken place, the contractor is responsible for notification of all applicable companies that excavation work is being performed. Location of utilities is a must before breaking ground. During excavation, the contractor is responsible for providing a safe work environment for employees and pedestrians. The contractor shall comply with all standards set forth in 29 CFR Subpart P.

Access and Egress is also an important part of excavation safety. Ramps used by equipment must be designed by a competent person, qualified in structural design.

No person is allowed to cross underneath or stand underneath any loading or digging equipment. Employees are to remain at a safe distance from all equipment while it is operational.

Inspect the equipment before every use.

Further instruction for excavation can be found in 29 CFR Subpart P.

Efforts to Improve Safety

Although construction is one of the worst industries in Europe in terms of safety, there have been, and are, various groups working towards improving construction conditions and safety. Construction conditions have improved ten-fold from 15 years ago, and as technology increases, so does the safety and working conditions of construction jobs. Organizations working toward improving construction safety include:

Hazards to non-workers

Many construction sites cannot completely exclude non-workers. Road construction sites must often allow traffic to pass through. This places non-workers at some degree of risk.

This sign and advisory plate penetrated the windshield and roof of a car in a side-impact test crash. A safer sign would have stiffer uprights, no advisory plate and the flashing light would be moved to the point of the sign to spread the impact force.

Road construction sites are blocked-off and traffic is redirected. The sites and vehicles are protected by signs and barricades. However, sometimes even these signs and barricades can be a hazard to vehicle traffic. For example, improperly designed barricades can cause cars that strike them to roll over or even be thrown into the air. Even a simple safety sign can penetrate the windshield or roof of a car if hit from certain angles. The majority of death in construction are caused by hazards relating to construction activity. However, many deaths are also caused by no construction activities, such as electrical hazards. A notable example of this occurred when Andy Roberts, a father of four, was killed while changing a light bulb at a construction site when he came into contact with a loose bare wire that was carrying two thousand volts of electricity and died. (August 1988 New York (U.S.A)). Events like this motivated the passing of further safety laws relating to non construction activities such as electrical work laws.

Applicable laws

Under European Union Law, there are European Union Directives in place to protect workers, notably Directive 89/391 (the Framework Directive) and Directive 92/57 (the Temporary and Mobile Sites Directive). This legislation is transposed into the Member States and places requirements on employers (and others) to assess and protect workers health and safety.

In the United States the Occupational Safety and Health Administration (OSHA) sets and enforces standards concerning workplace safety and health.
