Hot Stick and Insulated Boom Truck Protectant
Polywater® Wax was formulated especially for hot sticks and insulating boom arms to haze quickly and buff out easily. This carnuba-based wax restores the luster of the fiberglass to help protect the gel coat. It beads water on the insulating surface to inhibit tracking. Waxing the insulating portion of boom arms and buckets after cleaning them with Polywater Boom™ Wash, or following dielectric testing, is a recommended maintenance practice. See the sidebar for boom truck cleaning guidelines.
OSHA states that hot sticks, booms, and other live-line tools “… can become electrically unsafe because of … a combination of wetting, surface contamination, and a loss of surface gloss …” and ” … the best defense against accidents is a clean, glossy stick that causes water to bead up …”
The ANSI A92.2-1990 Standard (Section 5.4.3) also addresses proper dielectric testing intervals and field inspections for aerial truck testing. By following manufacturer and industry guidelines on the maintenance of boom trucks, aerial fleets will be safer and last longer. Polywater Wax and Boom Wash aid conformance to these industry practices.
Specifications and Applications:
Best Practice: Once a boom has been properly cleaned with Polywater Boom Cleaner (Polywater B-1, Polywater B-D72), Polywater Wax should be used to protect the gel coat surface and force water beading during misty or wet weather. All products used on boom trucks, including cleaners and protectants designed specifically for fiberglass booms, should be approved by the aerial lift manufacturer. American Polywater products are approved by boom truck manufacturers. Refer to the boom truck cleaning and maintenance best practice for more detailed information to keep your fleet in proper working order. www.polywater.com/wp-content/uploads/ pdf/LIT-BOOMguide.pdf
Industry Recommendations: Companies should follow boom truck manufacturer guidelines on the frequency of dielectric testing, proper cleaning practice, and other maintenance procedures. The ANSI A92.2-1990 Standard (Section 5.4.3) also addresses proper dielectric testing intervals and field inspections for aerial truck testing. Follow manufacturer and industry guidelines on the maintenance of boom trucks for safe and long-lasting aerial fleets
