Caution and warning barrier system for danger of electrical arcing
A caution and barrier system for danger of electrical arcing is disclosed. The caution and barrier system includes at least two elongate arms that attach to respective sides of a piece of equipment. The arms carry warning indicia. Some embodiments attach via traditional mounting hardware, while others mount magnetically to the equipment. The arms may also pivot and may comprise separate sections attached together by hinges. Yet other versions of the arms may be mounted on equipment using a multi-position magnetic mount. The caution and barrier system is particularly suitable for use with high voltage apparatus where electrical arcing is likely.
1. An electrical arc barrier and warning system, comprising:
a pair of elongate warning arms, each of the pair of warning arms carrying warning indicia and having an opening sized for a pin;
a pair of mounts attachable to respective sides of a piece of equipment, each of the mounts having
one or more permanent magnets attached to or arranged within a rear surface of the mounts, allowing the pair of mounts to be attached on respective sides of a piece of equipment, and
upper and lower guide blocks spaced from one another and defining a channel of sufficient width to accommodate one of the guide arms, the upper and lower guide blocks having aligned pin openings; and
pins removably arranged to extend through the pin openings of the guide blocks and the openings of the pair of warning arms to secure the pair of warning arms in positions either parallel to the channels or angled with respect to them.
2. The electrical arc barrier and warning system of claim 1 , wherein the openings sized for a pin are positioned proximate to a first end of each of the pair of warning arms.
3. The electrical arc barrier and warning system of claim 2 , wherein the openings sized for a pin extend generally vertically from a top face of each of the pair of warning arms, through a height of each of the pair of warning arms and open at a bottom face of each of the pair of warning arms.
4. The electrical arc barrier and warning system of claim 1 , wherein the pins are round.
5. The electrical arc barrier and warning system of claim 1 , wherein the pins have a polygonal cross-sectional shape.
6. The electrical arc barrier and warning system of claim 5 , wherein a shape of the openings matches the polygonal cross-sectional shape of the pins.
7. The electrical arc barrier and warning system of claim 1 , wherein the pair of warning arms are generally rectangular in shape.
8. The electrical arc barrier and warning system of claim 1 , wherein the rear surfaces of the mounts are ferromagnetic.
9. The electrical arc barrier and warning system of claim 1 wherein the warning indicia are selected from the group consisting of a color, a graphical indication, a placard, a sticker, and a word.
