- The safety net should be inspected regularly to ensure that it remains in good condition.
Types of Safety Nets
In construction, the type of safety net used depends on the project’s specifications, the level of risk, and the network’s intended purpose. Here are some common types of safety nets:
Fall Arrest Nets
These are safety nets designed to arrest falls from heights. They are typically made from high-strength nylon and polypropylene rope. Some are reinforced with steel cables to improve their resistance to abrasion and wear. Fall arrest nets need to undergo rigorous testing and comply with industry standards.
Debris nets are intended to catch and contain debris, materials, and tools that may fall from heights. They keep the surrounding area clean and safe. They are more lightweight than fall arrest nets and are usually made of polypropylene. They are often used in high-rise building construction.
Bridge, Tunnel and Mining Nets
Highway bridge construction, tunnel excavation, and mining all present unique hazards. Safety nets designed for these settings need to be specially designed to keep workers safe. They may need to be flame retardant, resistant to chemicals, and conform to specific standards for strength.
Personnel Safety Nets
Personnel safety nets are designed to protect against falls from elevated work platforms or walking surfaces. They are commonly used in aircraft and shipbuilding where large areas need protection. Personnel safety nets need regular inspection and maintenance to ensure they stay in good condition.
The Benefits of Safety Nets
The use of safety nets on construction sites has many advantages:
By preventing falls and catching debris, safety nets keep the work environment safe for workers and anyone else nearby.
When workers feel safe, they work more efficiently. Teams can work at higher levels and complete tasks without interruption.
The use of safety nets can reduce the cost of workers’ compensation and medical expenses. Further savings can be achieved by minimizing the amount of repeated work caused by accidents.
Compliance with Regulations
The use of safety nets is often mandatory due to industry standards and legal requirements. Using highly effective safety nets ensures that your site is always up-to-date with safety requirements.

Types of Safety Nets for Construction
There are several types of safety nets that can be used in construction sites to prevent falls and protect workers. Each type is designed for specific purposes and varying heights. The most commonly used safety nets in construction include:
1. Vertical safety nets
This type of safety net is suspended vertically close to the working surface to catch any objects or debris that may fall. According to the Health and Safety Executive (HSE), vertical safety nets are effective in reducing the risk of injuries resulting from falling objects by approximately 80%. The vertical net’s mesh size should be strong enough to hold impact forces generated by the falling objects, but small enough to prevent the objects from passing through.
2. Horizontal safety nets
Horizontal safety nets are installed horizontally below the work surface to catch people and objects that fall. They are suspended from an upper storey, scaffold, or the building’s structural frame. They are designed to minimize accidents by reducing the distance a person or object falls and providing a cushion-like landing to prevent injuries. Horizontal safety nets are highly effective in preventing falls from one level to another. According to research, horizontal safety nets are twice as effective as harnesses in preventing fatalities for height falls between 10 and 50 feet.
3. Debris safety nets
This type of safety net is typically used to prevent debris from falling, primarily in demolition or roof work. The debris net is installed vertically and hangs from the uppermost point of the construction site to its lowermost point, thereby enclosing the entire site. Debris safety nets are usually made of plastic-coated mesh materials, which are resistant to fire, water, rot, and high impact forces.
4. Personnel safety nets
Personnel safety nets are horizontal or vertical nets used to protect workers from falling from exposed edges or floor openings. They are designed to break the fall of a person and prevent serious injury or death and must comply with BS EN 1263-1 “Safety Nets – Part 1: Safety Requirements, Test Methods.” In construction, personnel safety nets are usually used in conjunction with other fall protection systems, such as anchors, guard rails, or harnesses.
5. Edge protection nets
Edge protection nets are safety nets that help prevent falls from the edge or fulcrum point of a building. They are installed in open perimeters to prevent workers or objects from falling in. Edge protection nets are easy to install and do not require complex anchorage points or structures. They are ideal for use in building construction and renovation and offer high flexibility and superior fall protection.
6. Cantilever crane loading nets
Cantilever crane loading nets are used when loading and unloading construction materials using a cantilever crane. They help protect workers by securing the load area and preventing falls from heights. Cantilever crane loading nets consist of horizontal and vertical cords connected at regular intervals and are engineered to support heavy loads.
7. Barrier nets
Barrier nets are safety nets designed to guide and protect workers and pedestrians from construction sites. They direct pedestrians towards a safe walking zone while providing a visual barrier to prevent unauthorized individuals from entering the construction site. Barrier nets can also be used in combination with other safety nets such as vertical debris nets or fall protection nets.
|No||Type of Safety Net||Usage|
|1||Vertical safety nets||To catch falling objects or debris close to working surfaces|
|2||Horizontal safety nets||To catch people and objects that fall from elevated areas|
|3||Debris safety nets||To enclose construction sites and prevent debris from falling|
|4||Personnel safety nets||To protect workers from falls from exposed edges or floor openings|
|5||Edge protection nets||To prevent falls from the edge or fulcrum point of a building|
|6||Cantilever crane loading nets||To secure the load area when using a cantilever crane|
|7||Barrier nets||To guide pedestrians and protect unauthorized entry from construction sites|
Standards for Safety Nets for Construction Sites
The use of safety nets in construction sites must follow certain standards set by international organizations. A safety net must be made from materials that can withstand certain impacts depending on the fall height. The mesh holes of the safety net must also be sized appropriately to prevent workers’ fingers or toes from getting caught. Here are some of the standards set by the International Organization for Standardization (ISO) and the Occupational Safety and Health Administration (OSHA):
The ISO 9001:2015 focuses on quality management systems in industrial environments. It provides guidelines on how to manage work processes and ensure that products and services meet customers’ requirements. In the context of safety nets, the ISO 9001:2015 provides guidelines on how to ensure that safety nets are made from high-quality materials, installed correctly, and inspected regularly.
OSHA Standard 1926.502(b)
OSHA Standard 1926.502(b) requires employers to provide safety nets when workers are exposed to falling objects or from heights above 6 feet. The safety nets must be installed as close as possible underneath the work area and extend outward from the work area to a distance that is equal to the fall height. The OSHA standard also requires that safety nets be capable of absorbing the impact of a dropped object and ensure that the fall height does not exceed 30 feet.
“Following safety net standards set by international organizations is crucial in ensuring the safety of workers in construction sites. It is important to choose safety nets made from high-quality materials and properly installed to prevent accidents and injuries.”

How Safety Nets are Supposed to Be Installed
Proper installation of safety nets is critical in preventing accidents and injuries in construction sites. Safety nets should be installed as close as possible to the work area and extend outward for a distance equal to the fall height. The safety net should be suspended over the workers, and the edges should be securely fastened to the structure or framework. The installation must be performed by qualified personnel with experience in safety net installation.
Types of Safety Nets
Safety nets are usually classified into three types, each with its unique design and function:
1. Vertical Safety Nets
Vertical safety nets are designed to surround the perimeter of the building or structure to protect workers and passerby below. It is usually installed on scaffolding, high-rise buildings, and bridges. The mesh size of vertical safety nets should not be more than 10cm to prevent workers and equipment from falling through.
2. Horizontal Safety Nets
Horizontal safety nets are installed beneath the working platform to catch falling workers and debris. It is usually used in high-rise construction or demolition work. The mesh size of horizontal safety nets should not be more than 6cm to minimize the risk of injury to workers who may fall onto the net.
3. Debris Safety Nets
Debris safety nets are used to prevent falling debris from damaging equipment or injuring workers below the construction site. It is usually installed beneath the roof or other elevated structures.
Each type of safety net comes with its benefits and limitations. Depending on the type of construction work, a combination of multiple nets may be used for optimal safety.

They are made of high-density polyethylene and are tied to the scaffolds or building structures to cover the area of the construction site. Debris nets are installed horizontally and vertically and can be recycled and reused for other projects.
2. Fall Arrest Nets
These are nets used when working at heights above the ground, which catches anyone who falls. They are made of synthetic fiber materials and have a high tensile strength that can withstand the weight of a person and absorb any energy that occurs during an impact. Fall arrest nets should be installed in a way that will protect the workers according to the requirements stated in the law.
3. Safety Nets for Roofing
Roof work is one of the riskiest types of construction work, and therefore safety nets for roofing are essential. They are made of nylon or polypropylene. They are stretchable, lightweight, and easy to install or remove. Roofing nets are designed to protect workers from falls or slips, especially during repairs or installation of roofs and gutters.
4. Personnel Safety Nets
These nets protect people who are working at lower levels and may suffer injuries from falling objects. Personnel safety nets are typically made from nylon mesh materials, which can be customized with various sizes to fit in required areas. These nets are ideal for use in construction projects where there are several levels, balconies, or roofs that require protection from falling objects.
5. Lifting Nets
Lifting nets are an essential piece of equipment when carrying equipment or materials from one floor of a building to another, or when moving construction materials from one area to another. They are available in different shapes and sizes, can be customized, and have reinforced edges to make them resistant to tearing. Lifting nets are made from high-strength synthetic materials such as nylon and polyester and can lift up to several tons.
6. Edge Protection Nets
These are nets used to safeguard the edges of work surfaces that are near openings, access points, or other places where people could fall. Edge protection nets are typically made of dense and dense fiber that has high elasticity and prevents people from falling. On construction sites, these nets are often used as safety barriers to avoid fall from heights.
7. Mesh Nets
Mesh nets are durable, lightweight, and easy to handle. They are ideal for working at heights, and they prevent falling debris from causing accidents. They can also be used as scaffold fencing, as they maintain visibility from the outside while providing an adequate amount of privacy for workers. Mesh nets are made of high-density polyethylene materials.
Benefits of Safety Nets for Construction Sites
Implementing safety nets in construction sites offers many benefits both for the workers and the overall project. Here are some advantages of having safety nets:
1. Protect Workers from Fatal Injuries
The primary purpose of safety nets is to catch any falling debris or workers and prevent fatal injuries in construction sites. According to the Bureau of Labor Statistics, falls cause the most deaths in construction sites, and safety nets can reduce these numbers significantly.
2. Increase Productivity
By providing safety nets, construction workers can focus more on the task at hand without worrying about their safety. This can boost productivity levels since they can work more efficiently without compromising their safety.
Although implementing safety nets requires an initial cost, it is a cost-effective solution in the long run. Workers’ compensation claims and medical expenses can cost more than the safety net installation and maintenance expenses.
