Disposable nitrile gloves offer protection for short-term contact with small amounts of certain lab chemicals. However, they are not suitable for extended contact with chemicals.

Here Are Some Guidelines:

  • Check for rips or punctures before use.
  • Select the correct size.
  • Remove and replace gloves immediately with new ones when chemical spills or splashes on them or there are signs of obvious contamination.
  • Never wash or reuse disposable gloves.
  • Always remove gloves before touching common objects such as doorknobs or door handles.
  • Do not wear gloves in hallways, offices, break rooms, elevators, restrooms, or any other public areas.
  • Glove removal (or "doffing") must be done carefully to avoid contact with the outside of the glove.
  • Dispose of chemically contaminated gloves in the yellow hazardous waste bag and biologically contaminated gloves in biohazardous waste bags

Nitrile gloves are preferred over latex because of their chemical resistance, their tendency to visibly rip when punctured, and to prevent possible latex allergies.

In addiKon to their chemical resistance profile, another reason that nitrile gloves are used instead of latex is to avoid skin allergies that can be caused by the proteins in the latex rubber. It is possible, however, for some individuals to be sensitive to the accelerators (chemical addiKves) in nitrile. Please report any allergies to reportit.kaust.edu.sa for recommendations and support.

Some More Information About Glove Tests And Information In Product Specifications

The EN ISO 374 standard ensures consistency in glove testing and helps users and safety professionals as they determine their chemical protection needs. Glove materials are evaluated on three criteria when exposed to chemicals: Penetration, Permeation and Degradation. The following information can be displayed in the product specifications or directly in the packing material.

Penetration

The EN ISO 374 standard ensures consistency in glove testing and helps users and safety professionals as they determine their chemical protection needs.

Permeation

The rubber and plastic films in gloves are the barriers to chemicals. It is therefore necessary to measure breakthrough times, or the time taken for the hazardous liquid to come in contact with the skin. Each chemical tested is classified in terms of breakthrough time performance level 0 to 6.

BBT (mins) Performance Level
>10 Level 1
>30 Level 2
>60 Level 3
>120 Level 4
>240 Level 5
>480 Level 6

Degradation

Sometimes chemical protective gloves can act as sponges, soaking up the liquids and holding them against the skin. This degrades the glove. Degradation is the change in one or more physical characteristics of a glove caused by contact with a chemical. Indications of degradation are flaking, swelling, disintegration, embrittlement, colour change, dimensional change, appearance, hardening, softening, etc.
