Klein Tools is recalling non-contact voltage testers with model number NCVT-5 with Laser Pointer with the following date codes 0518U-A1, 0618U-A1, 0718U-A1 and 0818U-A1. The product is being recalled due to a potential safety hazard where the NCVT-5 may not detect AC voltage in certain duplex outlets when used in the higher voltage setting, resulting in the operator falsely believing the electrical power is off, posing shock hazards. Please stop using your NCVT5 even if you have not experienced any issues. Please follow the customer instructions via the website below.

Klein Tools is recalling the CL110, CL210, CL310 and CL110KIT Digital Clamp Meters with the following date codes: 0875U-A1, 1015U-A1, 115U-A1, 1215U-A1, 0116U-A1, 0216U-A1, 0316U-A1 are included in this recall. "Klein Tools" and the model number are printed on the front of the clamp meters. The date code is printed on the back. The meters are black with a backlit LCD display and an orange trigger and clamp mechanism. The meters are rated CAT III 600 volts and measure voltage up to 600 volts and alternating current up to 400 amps. Only the meter in the CL110KIT is included in the recall. These meters are being recalled due to a fastener that can work itself loose overtime, potentially leading to a false reading when measuring voltage. This issue could indicate a reading of zero on energized systems resulting in the operator falsely believing the electrical power is off posing shock, electrocution and burn hazards. Consumers should immediately stop using the recalled digital clamp meters and contact Klein Tools to receive postage paid labels to return the clamp meters for free replacement units.

Fletcher Mining Equipment issued an important technical bulletin concerning nozzles on ANSUL fire suppression systems.

Fletcher is offering an upgrade on their equipment to the new ANSUL F-½ fire suppression nozzle. The redesigned F-½ nozzles have a rubber blow-off cap with retainer strap (Part Number 415108). The previous F-½ nozzles utilized the black plastic blow-off cap (Part Number 4120). See attached Fletcher Information Bulletin No. 117.

ANSUL F-½ nozzles (Part Number 16449) have been redesigned to accommodate a rubber blow-off cap with retainer strap. The redesign nozzle (part number is the same for both version of the F-½ nozzles) has a hole on the top the nozzle to enable the rubber cap to 'blow-off' when activated. The retainer strap keeps the cap with the nozzle. An 'R' will be stamped on the redesigned nozzle after the part number to help with identification. The blow off caps can only be used on the ANSUL F-½ fire suppression nozzle for which they were designed. See attached ANSUL Bulletin No. 5713.

Only ANSUL provided blow-off caps can be used on ANSUL fire suppression nozzles. Hydraulic hose protective caps cannot be used as blow-off caps on any ANSUL fire suppression system nozzles.

In a recent metal/nonmetal mine fatality, a mechanic was fatally injured while checking for a hydraulic leak on an Atlas Copco ST-8B Scooptram. While checking for a hydraulic leak, the victim leaned into the ejector plate relief port in the back of the loader bucket. The ejector plate of the bucket was retracted, crushing him against the back of the bucket.

Atlas Copco has developed a general hydraulic system safety notice that they are distributing to all of their LHD and Truck customers. The safety notice was developed to remind workers to take the necessary precautions before and during work on a hydraulic system.

The safety notice will be included in all Parts Books and Service Manuals for the model numbers in the attached service news.

J.H. Fletcher & Co. ("Fletcher") has previously manufactured a 2-bolt swinger L TOO. The design of this bolter (see attached drawing) has a small T-style ATRS and provides the operator the ability to install two bolts in a straight line by having a boom that can swing from side to side without resetting the ATRS. This design allows the boom to swing and in and out to address the drilling pattern. Approximately 32 machines have been distributed by Fletcher over the years with this design.

J.H. Fletcher & Co. (Fletcher) has identified a potential risk on DDR walk-thru machines with mast tilt using worm gear tilt boxes. The boxes, which are located on specific machines, provide the operator the ability to tilt the mast to different angles for drilling the roof and ribs. During a routine drilling process an operator had the mast tilted when the tilt box suddenly gave way. The mast rotated freely inward, narrowly missing the operator, who was standing at his work station.

Owners, Operators and Rebuilders of J.H. Fletcher & Co. Two-Leg Hinged Canopy
In November 2009 an accident occurred at a West Virginia mine. The information obtained by J.H. Fletcher & Co.

The damage to the tram canopy cylinder was so severe that the cylinder eye separated from the cylinder rod (Attachment 1). When this event took place the cylinder was no longer connected to the tram canopy and the canopy fell on the operator's head. The bolter had tram canopy extensions installed.

As a result of a fatal accident at the Century Mine in Ohio (USA) on August 8, 2011 involving a base lift jack, Joy has received a number of inquiries concerning whether or not our design is adequate. In this regard, it must first be noted that the base lift jack involved in the August 8, 2011, accident was not a JOY product. In addition, as a reputable supplier of equipment and systems to the mining industry, Joy Mining Machinery wants to assure our customers that we routinely review and evaluate our products for safety compliance and performance. Therefore, the purpose of this Service Bulletin is to inform users of JOY equipment that such a review has been conducted on the JOY powered roof support hydraulic base lift circuits to verify that the circuit does not have any potential issues with respect to pressure intensification as a result of design or functionality.

MSHA has been made aware of a hazardous condition that may exist in 600 volt and 1000 volt circuit breakers. This includes all frame sizes. The circuit breakers may appear to be new or rebuilt, but they have been changed from the manufacturer's original design. These mining circuit breakers, originally manufactured by Eaton Cutler-Hammer, may have been purchased either directly from the 3rd party or through a mining supply company. There is evidence that some of these circuit breakers have been modified by a 3rd party rebuilder with knock-off 600 volt and 1000 volt covers. The covers are of unknown construction and were not manufactured by Eaton. The labeling affixed to the breakers was also reproduced by the 3rd party rebuilder in an effort to make the circuit breakers look new and legitimate.

WASHINGTON, D.C. - The U.S. Consumer Product Safety Commission, in cooperation with the Petzl America Inc, announced a voluntary recall of Shock Absorbing Lanyards manufactured before May 2011 by Scorpio and Absorbica. Some lanyards are missing a safety stitch on the attachment loop, which can cause the lanyard to disconnect from the climbing harness, posing a fall hazard to consumers. One fall injury occurred in France due to this condition. Consumers should immediately stop using the lanyards and contact Petzl America Inc. for a free inspection and replacement of any non-conforming products. For additional information, mine operators should contact Petzl America Inc. at (877) 740-3826 between 8 a.m. and 5 p.m. MT, Monday through Friday or visit the firm's website at www.petzl.com.

Pyott-Boone Electronics issued a letter to inform users that Pyott-Boone Carbon Monoxide (CO) monitors may experience false detections when a radio frequency transmitter is transmitting nearby. The false detection will cause a detection spike and be recorded on the Atmospheric Monitoring System (AMS) event log. The spike will be an instant maximum value unlike a gradual increase with actual rising of CO levels.

This false detection is not limited to Pyott-Boone CO monitors. Other manufactures of CO monitors will experience the same false detections and/or erratic readings. Inspectors and mine personnel should be informed that a hand-held radio that is transmitting near a CO monitor could affect readings on the CO monitor and create inaccurate readings on the AMS.

Pyott-Boone Electronics and other manufactures are designing CO monitors to be more resistant to radio interference.
