The overtorqueing sometimes results in the failure (breakage and forceful scattering) of any of the items in the jury rig (e.g., socket, breaker bar, wrench, pipe) or of the components being worked on (e.g., nut, bolt, loadbinder), and when it does so, the fragments can injure workers in the line-of-fire.
A breaker bar is able to create a larger amount of rotational force compared to a standard socket wrench. A standard breaker bar is strong enough to allow the user to apply up to 2,500 pound-feet (3,400 N⋅m) of torque without breaking the bar. [3] A high-end 1/2" socket wrench can withstand a maximum of 500 pound-feet (680 N⋅m) of torque. [4]
A crash bar (also known as a panic exit device, panic bar, or bump bar) [1] [2] is a type of door opening mechanism which allows users to open a door by pushing a bar. While originally conceived as a way to prevent crowd crushing in an emergency, crash bars are now used as the primary door opening mechanism in many commercial buildings.
Angie's List and NBC Bay Area both highlighted an October 2002 ruling in a New Jersey Superior Court, which found that FPE (Federal Pacific Electric), the manufacturer of the Stab-Lok breakers and panels, "knowingly and purposefully [sic] distributed circuit breakers which were not tested to meet UL standards as indicated on their label".
A distribution board (also known as panelboard, circuit breaker panel, breaker panel, electric panel, fuse box or DB box) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits while providing a protective fuse or circuit breaker for each circuit in a common enclosure.
Utilizing a breaching tool is unnecessary if the door is unlocked and easy to open. [5] [3] [6] [1] If the door is locked, breachers can attempt to force inward-opening doors with a strong kick. The breacher will aim to hit the door near the locking mechanism, but not kick the doorknob itself as one can easily twist an ankle doing so. [7]
A drawbar is a defensive implement used to secure a door or gate in a medieval or Early Modern building such as a castle, [1] [2] but also churches and townhouses. When drawn across the full length of the door, it prevents the door or gate from being opened. To open the door or gate, the drawbar is pushed into a drawbar slot in the wall.
The Breakers is a Gilded Age mansion located at 44 Ochre Point Avenue, Newport, Rhode Island, US. It was built between 1893 and 1895 as a summer residence for Cornelius Vanderbilt II , a member of the wealthy Vanderbilt family .
