Construction work is a hazardous land-based job. Some construction site jobs include: building houses, roads, tree forts, workplaces and repair and maintain infrastructures. This work includes many hazardous task and conditions such as working with height, excavation, noise, dust, power tools and equipment. The most common fatalities are caused by the fatal four: falls, being struck by an object, electrocutions, and being caught in between two objects. Construction work has been increasing in developing and undeveloped countries over the past few years. With an increase in this type of work occupational fatalities have increased. Occupational fatalities are individuals who die while on the job or performing work related tasks. Within the field of construction it is important to have safe construction sites.

Construction fatality rates
In 2014, the United States had 4,679 fatal occupational injuries, an incidence rate of 3.3 per 100,000 full-time employed workers. In the same year, fatal work injuries in construction and extraction occupations increased 5%. One in five deaths of workers in 2014 were construction related. Construction has about 6% of U.S. workers, but 17% of the fatalities - the largest number of fatalities reported for any industry sector. In the United Kingdom, the construction industry is responsible for 31% of fatalities at work and 10% of major workplace injuries. In South Africa there are 150 fatalities and approximately 400 injuries each year related to construction sites. In Brazil, the incidence rate for all occupational fatalities is 3.6 per 100,000. (Little to no information regarding construction fatalities could be found in Asia, South American, Africa, and the Antarctic.)

Nature of hazards
Hazards to construction workers
The leading safety hazards on construction sites include falls, being caught between objects, electrocutions, and being struck by objects. These hazards have caused injuries and deaths on construction sites throughout the world. Failures in hazard identification are often due to limited or improper training and supervision of workers. Areas where there is limited training include tasks in design for safety, safety inspection, and monitoring safety. Failure in any of these areas can result in an increased risk in exposing workers to harm in the construction environment.
Falls are the leading cause of injury in the construction industry, in particularly for elder and untrained construction workers. In the Occupational Safety and Health Administration (OSHA) Handbook (29 CFR) used by the United States, fall protection is needed in areas including but not limited to ramps, runways, and other walkways; excavations; hoist areas; holes; form-work; leading edge work; unprotected sides and edges; overhand bricklaying and related work; roofing; precast erection; wall openings; floor openings such as holes; residential construction; and other walking/working surfaces. Other countries have regulations and guidelines for fall protections to prevent injuries and deaths.
Motor vehicle crashes are another major safety hazard on construction sites. It is important to be cautious while operating motor vehicles or equipment on the site. A motor vehicle should 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 a clear view of site from the rear window. All employees should be properly trained before using motor vehicles and equipment.
Employees on construction sites also need to be aware of dangers on the ground. Cables running across roadways were often seen until cable ramp equipment was invented to protect hoses and other equipment which had to be laid out. Other hazards found on construction site include asbestos, solvents, noise, and manual handling activities.
Education and safety
Construction workers need to be properly trained and educated on the task or job before working, which will assist in preventing injuries and deaths. There are many methods of training construction workers. One method is coaching construction site foremen to include safety in their daily verbal exchanges with workers to reduce work-related accidents. It is important that the workers use the same language to assure the best communication. In recent years, apart from traditional face to face safety knowledge sharing, mobile apps also make knowledge sharing possible.
Another method is ensuring that all workers know how to properly use electronics, conveyors, skid-steer, trucks, aerial lifts, and other equipment on the construction site. Equipment on the job site must be properly maintained and inspected regularly before and after each shift. The equipment inspection system will help the operator make sure that a machine is mechanically sound and in safe operating conditions. An employee should be assigned to inspect equipment to insure proper safety. Equipment should have lights and reflectors if intended for night use. The glass in the cab of the equipment must be safety glass in some countries. The equipment must be used for its intended task at all times on the job site to insure workers' safety.
Each construction site should have a construction site manager. Thisis an occupational health and safety specialist who designs and implements safety regulations to minimize injuries and accidents. He or she also is in charge of conducting daily safety audits and inspections to ensure compliance with government regulations. Most construction site managers have an entry level experience or higher degree.
Before any excavation takes place, the contractor is responsible for notifying all applicable companies that excavation work is being performed. During excavation, the contractor is responsible for providing a safe work environment for employees and pedestrians.
Access and egress are also important parts of excavation safety. Ramps used by equipment must be designed by a 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. Employees who have training and education in the above areas will benefit their co-workers and themselves on the construction site.
Road construction safety
The American Recovery and Reinvestment Act of 2009 created over 12,600 road construction projects, over 10,000 of which are currently in progress. Workers in highway work zones are exposed to a variety of hazards and face risk of injury and death from construction equipment as well as passing motor vehicles. Workers on foot are exposed to passing traffic, often at high speeds, while workers who operate construction vehicles are at risk of injury due to overturn, collision, or being caught in running equipment. Regardless of the task assigned, construction workers work in conditions in poor lighting, poor visibility, inclement weather, congested work areas, high volume traffic and speeds. In 2011, there were a total of 119 fatal occupation fatalities in road construction sites. In 2010 there were 37,476 injuries in work zones; about 20,000 of those were to construction workers. Causes of road work site injuries included being struck by objects, trucks or mobile equipment (35%), falls or slips (20%), overexertion (15%), transportation incidents (12%), and exposure to harmful substances or environments (5%). Causes of fatalities included getting hit by trucks (58%), mobile machinery (22%), and automobiles (13%).
Media safety campaigns
Road construction safety remains a priority among workers. Several states have implemented campaigns addressing construction zone dangers and encouraging motorists to use caution when driving through work zones.
National Work Zone Safety Awareness Week is held yearly. The national event began in 1999 and has gained popularity and media attention each year since. The purpose of the event is to draw national attention to motorist and worker safety issues in work zones.
Preventing accidents and improving safety
Site preparation aids in preventing injury and death on construction sites. Site preparation includes removing debris, leveling the ground, filling holes, cutting tree roots, and marking gas, water, and electric pipelines. Another prevention method on the construction site is to provide a scaffold that is rigid and sufficient to carry its own weight plus four times the maximum intended load without settling or displacement.
Ways to prevent injuries and improve safety include:
- Management safety
- Integrate safety as a part of the job
- Create accountability at all levels
- Take safety into account during the project planning process
- Make sure the contractors are pre-qualified for safety
- Make sure the workers are properly trained in appropriate areas
- Have a fall protection system
- Prevent and address substance abuse to employees
- Make safety a part of everyday conversation
- Review accidents and near misses, as well as regular inspections
- Innovative safety training, e.g. adoption of virtual reality in training
- Replace some of the works by robots (many workers may worry that this will decrease their employment rate)
- Adoption of BIM with three dimensional printing to make the building model first before put into real practice
The employees or employers are responsible for providing fall protection systems and to ensure the use of systems. Fall protection can be provided by guardrail systems, safety net systems, personal fall arrest systems, positioning device systems, and warning line systems. Making sure that ladders are long enough to safely reach the work area to prevent injury. Stairway, treads, and walkways must be free of dangerous objects, debris and materials. A registered professional engineer should design a protective system for trenches 20 feet deep or greater for safety reasons. To prevent injury with cranes, they should be inspected for any damage. The operator should know the maximum weight of the load that the crane is to lift. All operators should be trained and certified to ensure that they operate forklifts safely.
Operational Excellence Model to improve safety for construction organizations
There are 13 safety drivers associated with this model to improve safety for construction organizations:
- Recognition & Reward
- Employee Engagement
- Subcontractor Management
- Training & Competence
- Risk Awareness, Management & Tolerance
- Learning Organization
- Human Performance
- Transformational Leadership
- Shared Values, Beliefs, and Assumptions
- Strategic Safety Communication
- Just & Fair Practices and Procedures
- Worksite Organization
- Owner's Role
Each safety driver mentioned above has some sub-elements attributed to it.
Personal protective equipment
Hard hats and steel-toe boots are perhaps the most common personal protective equipment worn by construction workers around the world. A risk assessment may deem that other protective equipment is appropriate, such as gloves, goggles, or high-visibility clothing.
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.
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 it strikes from certain angles.
The majority of deaths in construction are caused by hazards relating to construction activity. However, many deaths are also caused by non construction activities, such as electrical hazards. A notable example of this occurred when Andy Roberts, a father of four, was killed in 1988 in New York 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.. Events like this have 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.
Europe
In the United Kingdom, the Health and Safety Executive (HSE) is responsible for standards enforcement, while in Northern Ireland, the Health and Safety Executive for Northern Ireland (HSENI) is responsible. In Ireland, the Health and Safety Authority (HSA) is responsible for standards and enforcement.
In Europe, the European Agency for Safety and Health at Work coordinates actions at the EU and national levels and the Directorate-General for Employment, Social Affairs and Inclusion is responsible for regulation at the EU level.
United States
In the United States, the Occupational Safety and Health Administration (OSHA) sets and enforces standards concerning workplace safety and health. Efforts have been made in the first decade of the 21st century to improve safety for both road workers and drivers in construction zone. In 2004, Title 23 Part 630 Subpart J of the Code of Federal Regulations was updated by Congress to include new regulations that direct state agencies to systematically create and adopt comprehensive plans to address safety in road construction zones that receive federal funding.
OSHA implemented the Final Rule to Improve Tracking of Workplace Injuries and Illnesses, which went into effect January 1, 2017. It requires employers to submit incident data electronically to OSHA. This data will enable OSHA to use enforcement and compliance assistance resources more efficiently. The amount of data required varies by company and industry.
