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 thiurames 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 hazardous 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 humidity, heat, at mini 5°C (41°F).

Laundering conditions

Before taking off the gloves, clean them as appropriate :

  • in use with paints, pigments and inks : wipe with a clean cloth dampened with a suitable solvent, and rub over with a dry cloth
  • in use with a solvent (diluents, etc…) : rub over with a dry cloth
  • in use with acids and alkalies : thoroughly rinse the gloves under running water, and rub over with a dry cloth

Caution : improper use of the gloves or submitting them to any 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 reusing them.


This product is not classified hazardous according to the regulation (EC) n°1272/2008 of the European Parliament and of the Council. This product does not contain more than 0.1 % of substance of very high concern (SVHC) or any substance included in the annex XVII of the regulation n° 1907/2006 of the European Parliament and of the Council (REACH).

Chemical chart

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.

Meaning of colors :

Used for high chemical exposure or chemical immersion, limited to breakthrough time based on a working day.
Used for repeated chemical contact, limited to total chemical exposure i.e. : accumulative breakthrough time 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
