3、r ANSI DIN CSA ISO Ansell Protective Products Chemical Resistance Guide 3.0 BACKGROUND INFORMATION The most effective and preferred way of dealing with potential risks in the workplace/environment is to eliminate them through engineering or administrative controls. When this is not feasible, actions

4、 must be taken to protect people from the harmful effects of the particular hazard. This may be done with the use of personal protective equipment (PPE), in this case protective gloves. Since PPE does not eliminate the risk, the equipment must be properly selected and employees must be sufficiently

5、trained to ensure adequate protection is achieved. A risk assessment must be performed in each workplace by a qualified health and safety professional to determine if hazards are present or are likely to be present. Based on this assessment, equipment will be selected which when used properly, preve

6、nts the employee from being affected by the hazardous condition.

7、ion Alliance (GDA) representative. The GDA representative can also provide product information including specifications for each of the approved products. 3.1 TRAINING Once appropriate PPE has been identified, training must be provided to ensure employees understand the following: Conditions and loc

8、ations where PPE is required; Type of PPE required; How to properly put on, wear, adjust, and take off PPE; PPE maintenance; PPE limitations, useful life, and disposal process. If the wrong equipment is used, or if the right equipment is used improperly, the person will not be fully protected and ma

9、y suffer harmful effects. 3.2 HAND PROTECTION When hands are exposed to hazards such as skin absorption of harmful substances, cuts and lacerations, abrasions, punctures, chemical burns, ionising radiation, electrical hazards or extreme heat or cold; the appropriate type of hand protection must be p

10、rovided. In most cases, suitable gloves will provide the necessary protection. In some cases, cuffs and sleeves may be needed. Occasionally, gloves may introduce additional risks. (Example, gloves should not be worn when working with rotating parts or equipment.) Choosing the right glove for the job

11、 is important since the wrong type may provide no protection at all. The Chemical Fact Sheet, Material Safety Data Sheet, and the safety professional should be consulted when choosing the proper glove. 3.3 SUPERVISOR RESPONSIBILITIES If you suspect Personal Protective Equipment is needed because of

12、exposures or potential exposures, contact a safety professional for an evaluation. Know PPE requirements for your area, availability and how to obtain it.

13、ing PPE as required, and enforce the use of PPE by others. Ensure PPE has been approved for use, is stored properly, and that employees have been trained as specified above. Where PPE is required, ensure an adequate supply is available, employees use PPE properly, and that damaged or defective equip

14、ment is not used. 3.4 SELECTION AND USAGE OF CHEMICALLY RESISTANT GLOVES Chemical resistant gloves are an important aspect of protection against hazardous materials. It is critical that users select the correct glove material based on the chemicals used and the gloves permeation data. Inappropriate

15、use of glove material may actually injure a worker as chemicals can quickly permeate the barrier. Please review the manufacturers, test data, and the included glove usage recommendations. Together the information will allow you to select the best glove material for your application. The appropriate

16、glove materials should be secured through the Qualified Source List. GUIDELINES FOR USE OF CHEMICALLY RESISTANT GLOVES All gloves are permeable Permeation is a process in which chemicals seep through glove material. This process does not always leave the glove visibly changed, which makes understand

17、ing the permeation process essential when selecting gloves. Breakthrough is the time lapse between first contact of the chemical and glove and the time to detection inside the glove. Degradation may cause such noticeable changes as swelling, discoloration, hardening or softening. There is no such th

18、ing as a “universal” chemically resistant glove Some laminate gloves offer protection against a wide range of hazardous chemicals, however, there may be limitations in dexterity, tactile sensitivity, ability to grip when wet, tear and puncture resistance.

19、Standard Number SB1 Issue Date: 02/17/2003 Global Manufacturing Standards Rev: Disposable gloves offer a decreased range of protection against hazardous chemicals but offer greater dexterity and mobility. Multiple gloves can be worn together Wearing one pair of thinner, more dexterous gloves over a

20、flexible laminate combines the advantage of both. When using this approach, be sure to use the smallest laminate size that will fit comfortably. This allows the greatest dexterity when worn under the outside glove. Reusable vs. Disposable gloves Care of re-usable gloves Immersion or prolonged contac

21、t is not common for chemical work in the laboratory. Therefore, reusable gloves do not need to be replaced very often. Inspect these gloves before each use, and replace whenever they become discolored or show signs of damage. Before reusable gloves are removed, thoroughly rinse them off and allow to

22、 air dry. Use of disposable gloves Disposable gloves provide a protective barrier when working with small amounts of chemicals for brief periods. If a disposable glove becomes degraded, remove immediately and replace with a new glove Never re-use disposable gloves. Glove Selection Glove selection mu

23、st be made from a knowledge base of the hazard, required use, and glove material. The following is a brief and incomplete guide for glove selection. As with any guide, should there be any doubts, consult a health and safety professional. Disposable:Vinyl, Latex, Nitrile o Dry Powders o Aqueous Solut

26、ithout going through pinholes, pores, or other openings. Individual molecules of the chemical enter the film and “squirm” through by passing between the molecules of the glove material. The glove may appear unchanged to the human eye. Chemical permeation can be described in simple terms by comparing

27、 it to what happens to the air in a balloon after several hours. Although there are no holes or defects, and the balloon is tightly sealed, the air gradually passes through (permeates) its walls and escapes. This simple example uses gas permeation, but the principle is the same with liquids or chemi

28、cals. Permeation data are presented in two values: Breakthrough Time and Rate. Breakthrough time: Breakthrough time (min.) is the time observed from the start of the test to first detection of the chemical on the other side of the material sample. This time represents how long a glove can be expecte

29、d to provide effective permeation resistance when totally immersed in the test chemical. Printed Copies Are Uncontrolled Page 6 of 7 Standard Number SB1 Issue Date: 02/17/2003 Global Manufacturing Standards Rev: Degradation: Degradation is a reduction in one or more physical properties of a glove ma

30、terial due to contact with a chemical. Certain glove materials may become hard, stiff, or brittle, or they may grow softer, weaker, and swell to several times their original size. If a chemical has a significant impact on the physical properties of a glove material, its permeation resistance is quic

31、kly impaired. For this reason, glove/chemical combinations rated “Poor” or “Not Recommended” in degradation testing were not tested for permeation resistance. Please note, however that permeation and degradation do not always correlate. 3.5 Definitions QUALIFIED SAFETY PROFESSIONAL A person that spe

32、nds the majority of their job in the health and safety field and has been trained in the identification and proper selection of Personal Protective Equipment, specifically gloves. LATEX Natural rubber, or latex is inherently elastic and resilient, plus it resists acids, alkalis, salts, and ketones.

33、Natural rubber latex is also blended with or dipped in other polymers to achieve a combination of features, such as the abrasion resistance of nitrile with the flexibility of latex. Latex gloves are suited for food processing, electronics assembly, and laboratory chemical handling. NEOPRENE Neoprene

34、 is a synthetic rubber developed as an oil resistant substitute for natural rubber. It is resistant to: acids caustics, alcohols, inks, refrigerants, ketones, oils, fats, grease fertilizers, cleaners, and detergents. Neoprene gloves are used in petrochemical, degreasing, refining, chemical processin

35、g, metal finishing, mechanical work, painting, bleaching, and commercial dishwashing. Printed Copies Are Uncontrolled Page 7 of 7 Standard Number SB1 Issue Date: 02/17/2003 Global Manufacturing Standards Rev: NITRILE Nitrile is a synthetic rubber that is also referred to as NBR or acrylonitrile-buta

36、diene. Nitrile gloves have superior puncture and abrasion resistance in addition to chemical protection, and they will not weaken or swell in aromatic or petroleum solvents, caustics, or animal fats. They are suited for chemical, food processing, stripping, degreasing, motor and engine manufacturing

37、, machining operation using cutting oil, coolants, electronics, acid etching, and chemical washing. NORFOIL This lightweight and flexible laminate material resists permeation by a wide range of solvents, acids, and bases. For example, Silver Shield brand gloves are often used under other gloves. The

38、y are useful for chemical and petrochemical laboratory work, spill cleanups, and HAZMAT control operations. VINYL Also known as polyvinyl chloride or PVC, vinyl is a plastic material that resists acids and alcohols, but not petroleum solvents. Economically substitutes, in many cases for natural rubber latex gloves. Vinyl gloves are used for a variety of industrial and food processing applications, intricate assembly work, laboratory research, and pharmaceutical manufacturing.
