2 GUIDE TO CHEMICAL-RESISTANT GLOVES THE MOST COMPLETE SINGLE USE NITRILE RANGE Chemical permeation testing of personal protective equipment is performed under laboratory conditions that cannot emulate every real world application. single use nitrile gloves can offer a variety of protection, from single splash protection (minor chemical exposure) to full chemical immersion applications, depending on the frequency and duration of exposure with any given chemical. Additional tests can be done by Lab for various chemicals and conditions upon requests. BREAKTHROUGH TIME AND PERMEATION PERFORMANCE LEVEL INDEX The level (0 to 6) indicates the time required for different chemicals to permeate through the glove. CHEMICAL PERMEATION CHART BREAKTHROUGH TIME PERFORMANCE LEVEL 1 minute Level 0 Not recommended 1 to 5 minutes - Splash protection only; change the glove immediately after contact! 6 to 10 minutes - Splash protection only; change the glove immediately after contact! > 10 minutes Level 1 Short contact only; change the glove after 10 minutes max! > 30 minutes Level 2 Medium protection, 30 minutes contact. > 60 minutes Level 3 Medium protection, 60 minutes contact. > 120 minutes Level 4 Good protection level. > 240 minutes Level 5 Very good protection level. > 480 minutes Level 6 Excellent protection level. TTL : total immersion chemical permeation breakthrough time. INT : intermittent contact chemical permeation breakthrough time, one minute immersion out of every ten, repeatedly. 2

CHEMICAL TERMS AND PROCESSES TO NOTE CAS NUMBERS The Chemical Abstract Services identification numbers provide unique identifiers for easy cross-reference to Material Safety Data Sheets (MSDS).

BREAKTHROUGH TIME The number of minutes from initial contact with a test chemical until it is first detected on the inside of the protective glove measured using sensitive analytical testing.

DEGRADATION Degradation is the physical change in a glove after chemical exposure: splash or immersion.

3 CHEMICAL TERMS AND PROCESSES TO NOTE CAS NUMBERS The Chemical Abstract Services identification numbers provide unique identifiers for easy cross-reference to Material Safety Data Sheets (MSDS). Some chemicals are widely known by other names. Several well-known synonyms appear in this guide and have the same CAS Number. BREAKTHROUGH TIME The number of minutes from initial contact with a test chemical until it is first detected on the inside of the protective glove measured using sensitive analytical testing. It is essentially the time period during which the glove is impermeable in contact with the given chemical. DEGRADATION Degradation is the physical change in a glove after chemical exposure: splash or immersion. The deleterious change in one or more physical properties of a protective glove material due to contact with a chemical. Degradation changes may include delaminating, discoloration, hardening, loss of tensile strength. HEAVY EXPOSURE In permeation testing this term refers to constant total immersion of the protective glove material in the test chemical that represents the worst type of heavy exposure. The ASTM F739 Test Standard and EN 374 Test Standard refers to this type of exposure. PERMEATION The process by which a chemical moves through protective gloves materials at the molecular level. The passage of a liquid or gas through protective gloves consists of three steps; absorption, diffusion and desorption. PENETRATION The process by which a substance moves through a closure, seam or pinhole in protective glove on a non-molecular level. CONCENTRATION The amount or mass of a constituent divided by the total mass of a solution. Acids and Caustics are solutions in water. In permeation testing of acids in particular, the concentration will affect the breakthrough time. More concentrated acids will permeate sooner than dilutions. CHEMICAL PERMEATION CHART 3

Choosing the right chemical protective glove is a very difficult task for health and safety managers.

Our tables give a comparable chemical protection level against 21 established chemicals, representing 19 different chemical classes.

These chemicals were chosen to give a wide range in potential chemical/barrier interactions, not on the basis of toxicity, although several of these materials are widely used in hazardous chemicals.

10 Choosing the right chemical protective glove is a very difficult task for health and safety managers. Choices are made following multiple criteria such as chemical, time of immersion, splash protection or heavy exposure, repetitiveness of tasks, etc. Our tables give a comparable chemical protection level against 21 established chemicals, representing 19 different chemical classes. These are generally the smallest molecules in their class and are readily available and reasonably easy to handle in a laboratory. These chemicals were chosen to give a wide range in potential chemical/barrier interactions, not on the basis of toxicity, although several of these materials are widely used in hazardous chemicals. The ChemRest laboratory can conduct more tests in case of uncertainty concerning the choice of protective glove with a given chemical.
