The Bucket Barricade protects a lineman from weather, inadvertent contact with energized equipment, and flying debris.

These are all very good reasons to have the Bucket Barricade at your work site. As with any new product, questions always arise as to the design. This slideshow answers some of those questions.

  • 1. Bucket Barricade Manufactured by Hastings Fiber Glass Products January 2012
  • 2. Protecting Lineman
    • The Bucket Barricade protects a lineman from weather, inadvertent contact with energized equipment, and flying debris.
    • These are all very good reasons to have the Bucket Barricade at your work site. As with any new product, questions always arise as to the design.
    • We will attempt to answer a few from each category by sharing our testing results.
  • 3. Protecting Lineman
  • 4. Is the “Glass” Bullet Proof?
    • While most linemen are not subjected to gun fire during the course of their work, the strength of the shield is often questioned.
    • The shield is produced from Lexan which is more impact resistance than Plexiglas, which is often referred to as bullet proof.
  • 5. Is the “Glass” Bullet Proof?
    • For the engineers, the impact resistance can be stated as:
    • Izod Impact Strength, Unnotched @ 0.125“ | 60 ft·lbs/in (no failure) | ASTM D256
    • Instrumented Impact, 0.125“ | >46 ft·lbs | ASTM D3763
    • Shear Strength @ Yield | 6,000 psi | ASTM D732
  • 6. .22 Cal Test
    • For the rest of us, we started with a .22 cal. long rifle Winchester ammunition fired from a Ruger Mark 1 pistol with a 6 7/8 inch barrel from a distance of 15 feet.
  • 7. .22 Cal Test
    • The bullet penetrated the surface and was entrapped in the material.
  • 8. .22 Cal Test
    • It almost broke through, but not quite.
  • 9. 3” .410 Shotgun Test
    • Next up was a 3” .410 shotgun shell loaded with 000 buckshot. This was fired by a Bond Arms double barreled derringer called a “snake slayer”.
    • Four of the reported five balls contained in the shell marked the Lexan.
  • 10. 3” .410 Shotgun Test
    • If you look really close, you can see a slight dent in the material, but certainly the snakes were saved.
    We have no idea where these pellets went after hitting the board!
  • 11. .45 Cal Test
    • Time for some real fire power. The next round fired was a .45 cal. fired from a Para-Ordnance P10-40 automat.
    First, the Lexan stopped the bullet! Well, stopped may not be the correct term, but it did not pass through.
  • 12. .45 Cal Test
    • The bulge in the back of the Lexan was almost as impressive as the final resting place for the bullet. Having bent somewhat in stopping the bullet, the Lexan promptly threw the bullet back towards its point of origin, allowing us to find it.
  • 13. .357 Mag Test
    • Time for the magnums!
    • The first round of the .357 mag. fired from a S&W model 19 with a 4 inch barrel made for a quick and somewhat clean hole.
  • 14. .357 Mag Test
    • The exit wound showed some melting and some fracturing depending on your point of view.
  • 15. .44 Mag Test
    • The .44 mag. also pierced the Lexan by a combination of melting and fracture. Not exactly bullet proof, but then not exactly ordinary bullets.
  • 16. Product Details
    • So who sold us this product and what did they expect us to do with it?
  • 17. Product Details
    • Kirk said this would protect us from accidentally contacting something behind us. If so, it needs to be good electrically. How good is it?
    • For the engineers, it is: Dielectric Strength, in air at 0.125" | 380 V/mil | ASTM D149
    • What does that mean for the user? Why doesn’t it have a voltage rating?
  • 18. Product Details
    • When insulating properties, Lexan is so much better than air that rating the board would be based only on how far you stay away from the edge. The material will not be punctured from too much voltage.
    • The next slide shows two pieces of metal foil are placed on each side of the Lexan and energized to 80kV. Corona from the corners along with streamers surrounding the electrodes on each side can be seen as a faint blue arc. The lights were off to make the photo more visible.
  • 19. Product Details
  • 20. Product Details
    • For a better idea of how Lexan responded to a high voltage, the next slide is a video of the Lexan with 80kV applied.
  • 21. Product Details
    • Lexan has documented thermal properties such as:
    • Coefficient of Thermal Expansion | 3.75 x 10-5 in/in/ºF | ASTM D696
    • Coefficient of Thermal Conductivity | 1.35 BTU in/hr ft 2ºF | ASTM C177
    • Heat Deflection Temperature @ 264 psi | 270ºF | ASTM D648
    • Heat Deflection Temperature @ 66 psi | 280ºF | ASTM D648
    • Brittleness Temperature | -200ºF | ASTM D746
    • Shading Coefficient, Clear 0.125" | 1.02 | ASHRAE
    • Shading Coefficient, Gray 0.125“ | 0.70 | ASHRAE
    • U factor 0.25" (summer gain, winter loss) | 0.90, 0.96 BTU/hr ft 2ºF
  • 22. Product Details
    • So what really happens when Lexan is exposed to extremely hot temperatures for a short period of time. The following video will show you (in a very unscientific but practical fashion) what happens.
