When energized conductors or equipment require temporary support or repositioning for maintenance, line workers depend on insulated conductor support tools to ensure their safety. These essential tools isolate energized components from ground potential and other phases, playing a vital role in jobsite safety. This guide covers best practices for testing, storing, and maintaining insulated tools, helping you ensure safety and reliability.

Factory Testing for Insulated Support Tools

Before insulated support tools leave the factory, they undergo rigorous testing to meet stringent safety standards:

• High-Voltage Testing: Each tool is tested at 100 kV per foot during production.

• Identification: A label is added, showing the testing date.

• Comprehensive Production Testing: Includes checks for electrical leakage after moisture exposure, atmospheric wicking, dimensional accuracy, deflection, crushing resistance, and visual inspections.

In-Service Testing and Maintenance Essentials

To ensure continued performance, regular testing of temporary support tools is crucial, adhering to ASTM and OSHA standards.

ASTM Testing Guidelines:

• Follow ASTM F3121 standards for periodic equipment testing.

• Test equipment at 75 kV per 12 inches under wet conditions, as outlined in the standard.

OSHA Electrical Testing Requirements:

• Conduct electrical testing at least every two years, per OSHA 1926.957(b)(3)1926.957 - Live-line tools. | Occupational Safety and Health Administration, or whenever the tool’s insulating properties are in doubt.

• Perform testing before returning any repaired tool to service.

• Clean the tool thoroughly before testing, avoiding silicone or wax, as they can produce false positives if the surface finish is worn.

Maintenance Best Practices

Proper maintenance extends the life of insulated tools and ensures optimal performance.

• Keep Tools Clean: Maintain a glossy surface finish to support dielectric performance.

• Inspect and Clean Regularly: Use silicone wipes before each use to remove contaminants.

• Store Properly: Protect tools from physical damage, pollutants, and UV exposure by storing them in a bag, truck or trailer rack, or other protective enclosures after use.

• Remove Damaged Tools Immediately: If damage is found or suspected, remove the tool from service. Tools with exposed fiberglass must be destroyed to prevent potential safety risks.

By following these best practices for testing, maintaining, and storing insulated tools, you can enhance jobsite safety and ensure these critical tools perform reliably over time.
