Instructions for users of rubber glove and general care of rubber insulating equipment.

Warning: Death or serious bodily injury may result from the following:

  • Failure to wear gloves while working with or close to "hot" electrical lines or components;

  • Wearing gloves which are in less than good condition;

  • Failure to wear leather protectors over gloves while in use;

  • Failure to follow instructions below or safety instructions given by employer.

Important: These warnings and instructions should be given to the user of the gloves along with complete safety training and instruction in handling of "hot" electrical wire and components. These instructions cannot anticipate all of the potential circumstances the wearer of these gloves may confront. Therefore, these instructions do not contain all possible instructions. Rather, the wearer must receive complete and adequate safety training as to the use of these gloves and his/her job duties.

Care and use of insulating gloves:

  • Proper care and use of these products is essential to the safety of the user. Gloves must be inspected visually by the wearer prior to every use. Such inspection must include the inside and the outside surfaces of the gloves.

  • Gloves can be damaged by many chemicals, especially petroleum based products, such as oils, gasoline, hydraulic fluid, inhibitors, hand creams, pastes, and salves. If contact is made with these or other petroleum based products, the contaminant must be wiped off immediately. Gloves should be cleaned using a mild soap. After washing, rinse thoroughly with clear water and air dry. If any signs of physical damage or chemical deterioration are found, such as swelling, softening, hardening, stickiness, and/or ozone deterioration, the gloves must be discarded.

  • Death or serious bodily injury may result from using gloves containing signs of physical damage or chemical deterioration.

  • Gloves should be stored in a protective bag when not being used.

  • Follow your employer's safety work practices and procedures.

  • Death or serious bodily injury may result from wearing rings, watches, jewelry, or other sharp objects while wearing rubber gloves.

Leather Protectors:

  • Rubber insulating gloves should always be used with leather protector gloves. These protector gloves must be inspected at the same time the rubber gloves are inspected. Look for metal particles, embedded wire, abrasive materials or any substance that could cause puncture , abrasions, contamination or deterioration. 

  • Adequate flashover distance between the top of the protector and the bead of the rubber glove should be maintained. The minimal uncovered distance should be one inch for every 10,000 volts-AC (by glove rating).

Thank you for your business.

All retested equipment is provided with documentation on the testing performed by Skarshaug Testing Lab (STL). Enclosed is a copy of the packing list and test reports. STL keeps electronic records of every item tested. Please contact if any documentation is missing or needed. 

Packing list provided with tested equipment.

The included packing list, in general, includes details of the quantity of each type of item returned in the top section. Any additional items (new orders, replacements or backordered items) will be listed in detail toward the bottom. Please note the number of packages or cartons to ensure everything was received.


Test reports provided with tested equipment.

Test reports are provided for each type of equipment (rubber gloves, rubber sleeves, hotsticks, cover-up equipment, etc.). Each report will list the date tested, technician, the governing standard for the test (typically an ASTM standard), and an itemized listing of the test results. In general, "P" denotes a passing result and any negative or non-passing result will be defined by the type of failure. All items have both a visual and dielectric portion of the testing process. Failure at either a visual or dielectric basis is cause for the item to be removed from use.


Stamping and marking of the tested equipment.

All tested items are stamped or marked with the date of the dielectric test and the voltage tested/rated. Please note the voltage tested is typically higher than the maximum voltage at which the equipment shall be used. For example, a class 0 rubber glove has a rated voltage of 5,000 volts-AC; the gloves are tested at 5,000 volts-AC but can only be used up to 1,000 volts-AC. Failures are marked with a "REJECT" stamp and rubber gloves are also defaced by cutting off the beaded-cuff of the glove.

Please note the markings on the equipment match the test report. The test report is itemized either by serialized markings (permanent identifier) or a report number.
