When to Replace a Bucket Liner

A bucket liner, also known as a bucket insert, is made of insulating material such as polyethylene, and it sits inside the bucket of a utility truck where operators stand while working. Users will determine by their safety work rules if liners are used. If they are used, the liner must be inspected and tested to verify it provides the protection expected. The liner must rest on the platform floor and be retained to prevent loss when traveling. Testing and replacing a bucket liner as needed is an essential part of maintaining the safety and integrity of a bucket truck. Here are some key considerations for determining when to replace a bucket liner: 

Visible Damage

Inspect the bucket liner regularly for any signs of damage, such as cracks, punctures, or wear. Even minor damage can compromise the insulation and safety of the liner, which may require replacement. Damage which created thin spots of the liner wall thickness reduces the insulating value. Do not drill holes in a liner below the lip. Holes can be drilled in the top lip only to retain the liner in the platform, never in the walls or floor. Scuff pads can be installed on the floor of the liner to reduce the wear and damage from tools. 

Age and Usage

Bucket liners have a finite lifespan, and their durability can be affected by factors such as frequency of use and environmental conditions. Replacement is dependent on the condition and the requirement to pass the electrical tests annually. The liner condition determines when it should be replaced. 

Electrical Testing

Bucket liners are designed to provide electrical insulation to protect workers from electrical hazards when working near live power lines. Regular electrical testing will assess the integrity of the insulation and identify any weaknesses or failures. If the liner fails, the electrical test it must be replaced promptly. Some users repair liners, if repaired it must have a qualification test performed before returning to service. 

Regulatory Compliance

Regulatory agencies such as OSHA (Occupational Safety and Health Administration) may have specific requirements regarding the inspection and maintenance of bucket trucks, including the condition of bucket liners, if equipped. Compliance with these regulations is essential for ensuring the safety of workers and avoiding potential fines or penalties. 

Manufacturer Recommendations

Follow the liner manufacturer's recommendations for maintenance and replacement of bucket liners. Manufacturers may provide specific guidelines based on the type of liner, environmental conditions, and usage patterns. Users should consider liners with interior steps and clips or covers to retain when traveling. 

Safety First

When in doubt, err on the side of caution and replace the bucket liner if there are any concerns about its safety or integrity. The safety of workers should always be the top priority when operating bucket trucks or any other aerial lift equipment.
