Introduction

The installation of gabion baskets involves the labor-intensive process of unfolding and assembling wire mesh containers by hand at the desired location, securing them together to form a stable structure. This method allows for precise placement and alignment, ensuring that the gabion baskets fit the specific requirements of the site. The process also entails filling the baskets either by hand placement or using an excavator, depending on the scale and time efficiency required. Meticulous preparation and execution are crucial to achieve the desired outcome in erosion control, retaining walls, and other applications.

Hazards

Main hazards/dangers associated with the installation of gabion baskets include the following:

1. Manual handling: The process of unfolding and assembling wire mesh containers can involve lifting and carrying heavy materials, which can put strain on workers’ backs, shoulders, and other musculoskeletal systems. This can lead to injuries such as strains, sprains, and even more serious conditions like hernias or disc problems.

2. Falls from height: Depending on the location and scope of the installation, workers may need to work at heights to properly position the gabion baskets. This can increase the risk of falls if proper safety measures are not in place, such as working from secure scaffolding, using appropriate fall protection equipment, or ensuring stable ground conditions.

3. Machinery operation: When using an excavator to fill gabion baskets, there is a risk of accidents or injuries related to the operation of heavy machinery. This includes the potential for collisions, entanglement hazards with moving parts, and risks associated with improper machinery maintenance or misuse.

4. Falling objects: During the process of filling the gabion baskets, there is a risk of rocks or other materials falling and striking workers below. This can cause serious injuries, such as head trauma, fractures, or lacerations.

5. Manual handling of fill material: If the baskets are filled manually, workers may face hazards related to lifting and carrying heavy rocks or other fill material. This can lead to the same risks associated with manual handling, such as strains or sprains.

6. Eye and respiratory hazards: Dust and debris generated during the installation process can pose risks to workers’ eyes and respiratory systems. This is especially true when using machinery to fill the baskets, as the movement of rocks and materials can create airborne particles that can irritate or damage the eyes and lungs.

7. Environmental hazards: Depending on the location and nature of the project, workers may be exposed to potential hazards from the environment, such as extreme weather conditions, unstable ground conditions, or exposure to wildlife or poisonous plant species.

It is essential to identify these hazards and implement appropriate control measures to minimize the risks associated with the installation of gabion baskets.

Installation of Gabion Baskets : Rules

  • Do conduct a thorough site inspection and risk assessment prior to commencing work. Identify potential hazards, such as unstable ground, overhead power lines, or nearby structures, and implement appropriate control measures.
  • Do ensure that all workers involved in the installation process receive proper training and instruction on the safe handling and assembly of gabion baskets. This includes understanding the correct use of tools and equipment.
  • Do wear appropriate personal protective equipment (PPE) such as safety helmets, high visibility vests, steel-toe boots, and gloves, to protect against potential hazards on-site.
  • Do follow safe manual handling practices when lifting and carrying gabion baskets, ensuring that bending and lifting techniques are used to minimize the risk of back or musculoskeletal injuries.
  • Do inspect the gabion baskets for any defects or damage prior to installation. Damaged baskets should not be used as they may compromise the integrity of the structure. Any defects should be reported and replaced before proceeding.
  • Do use sufficient manpower when installing gabion baskets manually to avoid overexertion or strain. Collaboration and teamwork are key to ensuring safe and efficient installation.
  • Do secure the gabion baskets together firmly during assembly using approved fastening methods, such as lacing wire or hog rings, to prevent displacement or collapse during filling or adverse weather conditions.
  • Do ensure that all fill materials are properly placed and distributed within the gabion baskets, following the specified guidelines and design requirements, to achieve the desired stability and durability of the structure.
  • Do adhere to manufacturer’s instructions and industry best practices when using equipment, such as excavators, for filling larger gabion baskets. Ensure operators are competent and familiar with the specific machinery being used.
  • Do regularly inspect and maintain equipment to prevent malfunctions or breakdowns that could jeopardize worker safety. Ensure all machinery is properly serviced and in good working condition.
  • Remember, these are just some of the safety-related “Dos” associated with the installation of gabion baskets. It is essential to consult with relevant regulations, industry standards, and specific site requirements to develop a comprehensive safety plan.

Installation of Gabion Baskets : Warnings

  • Don’t attempt to install gabion baskets without proper training or instruction. Be sure to receive proper training and supervision before carrying out any installation tasks.
  • Don’t work alone. Always work in teams of two or more individuals to ensure safety and provide assistance if needed.
  • Don’t overload the gabion baskets with excessive fill material. Follow the manufacturer’s guidelines and specifications regarding the maximum weight and capacity of the baskets.
  • Don’t stack the gabion baskets higher than the recommended height. Exceeding the maximum height can compromise the stability of the structure.
  • Don’t ignore weather conditions. Avoid working in extreme weather conditions such as high winds, heavy rain, or snow, as these conditions can increase the risk of accidents or injuries.
  • Don’t neglect to wear suitable personal protective equipment (PPE). Always wear appropriate PPE, including safety goggles, gloves, hard hats, and steel-toed boots, to protect yourself from potential hazards.
  • Don’t use damaged or defective gabion baskets. Inspect the baskets before installation and do not use any that are bent, torn, or otherwise compromised.
  • Don’t place your fingers or hands inside the gabion baskets while filling them with rock or fill material. Use appropriate tools or equipment to avoid potential injuries.
  • Don’t stand directly underneath a suspended load when using an excavator or other machinery to fill the gabion baskets. Stay clear of the path of any lifting equipment or machinery to prevent injury.
  • Don’t rush the installation process. Take your time to ensure proper alignment and securing of the gabion baskets. Rushing can lead to mistakes or accidents.
  • Remember, this list of safety-related “Don’ts” is not exhaustive. It is essential to conduct a comprehensive risk assessment and develop a specific method statement for your gabion basket installation project to address all relevant safety considerations.
