Chemical

Each letter stands for a tested chemical from a fixed list, for example A for methanol and K for sodium hydroxide. The type above it, A, B or C, indicates against how many of those substances the glove holds up for at least 30 minutes: type A against six, type B against three and type C against one.

Check the manufacturer's chemical resistance list, not just the letters on the glove. It lists the breakthrough time per substance in classes, from less than 10 minutes to more than 480 minutes. That time runs from first contact, even if you take the glove off in between.

The symbol with the text VIRUS means the glove has been tested according to EN ISO 374-5 for protection against viruses, in addition to bacteria and fungi. A glove without that marking only protects against bacteria and fungi. This distinction is important in healthcare, in laboratories and in cleaning work where you come into contact with potentially contaminated material.

You choose a disposable glove for short contact or splashes, such as laboratory work, painting or topping up fluids; you take it off as soon as it is dirty. A reusable glove is thicker and suitable for prolonged contact or immersion, such as cleaning and degreasing. With reusable gloves, pay attention to the breakthrough time, as it continues across multiple uses.

The deeper you put your hands into a liquid, or the more splashes are released, the longer the glove needs to be. A standard glove ends at the wrist, while models of 35 to 45 cm also protect your forearm. Fold the cuff over slightly when you work with your hands raised, so that liquid does not run down the inside towards your arm.
