Operating instructions

Instructions for use

  • It is recommended to check that the gloves are suitable for the intended use, because the conditions of use at workplace may differ from the "CE"-type tests.
  • Persons sensitised to dithiocarbamates and thiazoles should not use these gloves.
  • Put the gloves on dry, clean hands.
  • Do not use the gloves in contact with a chemical for a duration in excess of the measured breakthrough time. Refer to the website www.mapa-pro.com or contact the Technical Customer Service - MAPA PROFESSIONNEL (stc.mapaspontex@mapaspontex.fr) in order to know this breakthrough time. Use 2 pairs alternatively when in long duration contact with a solvent.
  • Turn the cuff end down in order to prevent a chemical from dripping onto the arm.
  • Inspect the gloves for cracks or snags before reusing them.

Storage conditions

Store the gloves in their original packaging protected from direct sunlight and heat sources.

Laundering conditions

Before taking of the gloves, clean them as appropriate :

  • in use with a solvent (Naphta, etc...) : rub over with a dry cloth
  • in use with acids or alkalines : thoroughly rinse the gloves under running water, and rub over with a dry cloth

Caution : improper use of the gloves or submitting them to a cleaning or laundering process which is not specifically recommended can alter their performance levels.

Drying conditions

Ensure the inside of the gloves is dry before putting them on again.

*not normalized result

Overall Chemical Protection Rating

Protection rating is determined by taking into account the effects of both permeation and degradation in an attempt to provide users with an overall protection guideline when using our glove products against specific chemicals.

Used for high chemical exposure or chemical immersion, limited to BTT based on a working day.

Used for repeated chemical contact, limited to total chemical exposure i.e. : accumulative BTT based on a working day.

Splash protection only, on chemical exposure the gloves should be discarded and new gloves worn as soon as possible.

Not recommended, these gloves are deemed unsuitable for work with this chemical.

NT : Not tested

NA : Not applicable because not fully tested (only degradation OR permeation results)

The chemical test data and overall chemical protection rating should not be used as the absolute basis for glove selection. Actual in-use conditions may vary glove performance from the controlled conditions of laboratory tests. Factors other than chemical contact time, such as concentration and temperature, glove thickness and glove reuse, may also affect performance. Other glove requirements, such as length, dexterity, cut, abrasion, puncture and snag resistance, or glove grip also need to be considered in making your final selection.
