MARKING:

All gloves and sleeves are clearly and permanently marked with a label identifying the name of the manufacturer, the appropriate ANSI/ASTM number (ANSI/ASTM D 120 for gloves and ANSI/ASTM D 1051 for sleeves), type, class and size (and right or left for sleeves). This nonconducting label is the color specified for each voltage class and is confined to the cuff portion of the glove or the shoulder flap area of the sleeve.

Class 00 – Beige

Class 0 – Red

Class 1 – White

Class 2 – Yellow

Class 3 – Green

Class 4 – Orange

Gloves and sleeves manufactured for European Community (EC) are marked as above. In addition to this marking, gloves and sleeves are marked with a Category III CE marking and the marking requirements of the relevant EN standard. This additional marking includes the name of the manufacturer, class/category, month and year of manufacture, size, a double triangle symbol and a rectangular band permitting the marking of the date of entry into service and the dates of periodic inspections and tests. WHITE RUBBER STRICTLY PROHIBITS THE PUNCHING OF HOLES IN ANY CLASS OF GLOVES OR SLEEVES AS A MEANS OF IDENTIFYING PERIODIC TESTS AND INSPECTIONS.

CUSTOM MARKING AND BANDING OF PRODUCTS IS AVAILABLE. CONTACT WHITE RUBBER DIRECTLY FOR ADDITIONAL INFORMATION.

STORAGE:

Gloves and sleeves should be stored in their container or package. Care should be taken to ensure that the gloves or sleeves are not compressed or folded, or stored in close proximity to steam pipes, radiators or other sources of artificial heat or exposed to direct sunlight, artificial light or other sources of ozone. It is recommended that the ambient storage temperature be between 10° C (50° F) and 21° C (70° F).

EXAMINATION BEFORE USE:

Gloves should be inflated to check for air leaks. Before each use, gloves or sleeves should be visually inspected on both the inside and outside surfaces. If either a pair of gloves or sleeves is thought to be unsafe, the complete pair shall not be used and should be returned for testing.

PRECAUTIONS IN USE:

Gloves or sleeves should not be exposed unnecessarily to heat or light be allowed to come in contact with oil, grease, turpentine, white spirits, strong acid or compounds containing copper (such as those found in some wood preservatives).

Soiled gloves and sleeves should be washed with mild soap or mild nonbleaching detergent and water, thoroughly dried and dusted with talc. If compounds such as tar and paint continue to stick to the glove or sleeve, the affected parts should be wiped immediately with a suitable solvent, avoiding excessive solvent use, and then immediately washed and treated as prescribed. Petrol, paraffin or white spirits should not be used to remove such compounds. Gloves and sleeves which become wet in use or by washing must be dried thoroughly, but not in a manner that will cause the temperature of the gloves or sleeves to exceed 65° C (149° F).

PERIODIC INSPECTION AND ELECTRICAL TESTING:

Gloves of Classes 00, 0, 1, 2, 3, and 4, held in storage, should NOT be used unless they have been tested within a maximum period of 6 months. The tests shall consist of an air inflammation to check for air leaks, visual inspection while inflated, and then a routine dielectric test in accordance with the EN and ASTM standard for the Class being tested. In-service gloves shall be retested at a minimum of every 6 months.

Sleeves of Classes 0, 1, 2, 3, 4, held in storage, should NOT be used unless they have been tested within a maximum period of 12 months. In-service sleeves shall be retested at a minimum of every 12 months.

Gloves and sleeves in storage as new product shall be tested at a minimum of every 12 months.
