Systems and methods of using the system for providing warning to ladder users of hazardous locations along its span are disclosed. The system comprises a contact strip or contact device located on a specific rung, step or tread on or in close proximity to the hazardous location along the span of the ladder erected for use that when engaged by the weight of a person stepping on said rung, step or tread, the contact strip or device is engaged, activating an electronic warning signal. This signal can occur in a form or combination of forms such as, but not limited to, an auditory alarm, a vibration or a light. This contact strip or device and its accompanying warning signal are powered by a form of electric current provided from any regularly available forms of power such as but not limited to, removable batteries, re-chargeable batteries or power-packs that may be directly plugged into any permanent source of power. This system may comprise a light beam transmitter; said beam can be of visible or invisible light that is generated in a concentrated-beam form across the width of the ladder where it is reflected by a reflecting device on the opposite side of the width of the ladder. Said beam spans a left-to right path across the width of the ladder. Once the user of the ladder moves into the beam as it is placed at or in close proximity to the hazardous location and said user breaks the plane of said light beam this action further activates an electronic warning signal. This signal can occur in a form or combination of forms such as but not limited to, an auditory alarm, a vibration or a light. This beam and its accompanying warning signal are powered by a form of electric current provided from any regularly available forms of power such as but not limited to, removable batteries, re-chargeable batteries or power-packs that may be directly plugged into any permanent source of power. This system may be constructed in a manner that it is installed permanently within the structure of the ladder at set locations consistently considered to be potentially hazardous locations. This system may be constructed as a self-contained unit that is portable, removable and installable at any location along the run of a ladder that its user may deem appropriate. This portable/removable unit is constructed in a housing or container that would facilitate the easy attachment to the ladder structure and made in such a manner to allow for adjustable width to facilitate a variety of installation applications across a spectrum of ladder sizes and designs.

A wrench for use with mine wall support bolts is disclosed. The wrench includes an elongated shaft shaped to be engaged and driven by a mine bolting machine. The shaft is coupled to a bolt socket by a universal joint. A removable, resilient, impermeable sleeve surrounds the universal joint. The sleeve is formed of a non-metallic material having physical properties which limit the movement of the universal joint and also seal the joint against infusion of solid and fluid matter. The sleeve is secured in place by a removable clamp.
