This guidebook contains information on hazardous chemicals and recommendations for the selection of chemical protective clothing materials based on published and unpublished scientific test data. Most of the chemical resistance data are generated in accordance with the standardized test methods. NO attempt has been made to ensure either the accuracy or precision of these compiled data. The Guide also does not take into consideration the intended use or physical demands (resistance to tear, puncture resistance, etc. or heat and flames) of the chemical protective clothing. These factors are critical in the selection process. A person competent in the selection of chemical protective clothing such as an Industrial Hygienist or a Safety Professional with training in this area ensures the selections based on this Guide are carried out properly.
The Guide only addresses chemical protective clothing against chemical hazards and exposures. Clothing without barrier materials such as laboratory coats are not included in this Guide.
The revised and updated version of the sixth edition of the Quick Selection Guide to Chemical Protective Clothing includes additional selection recommendations from a large number of new test data. We urge the users of the Guide to get familiar with the new products and the revised names of existing products on the market listed in Sections II and VII before going into the selection process.
The chemical index includes many new chemicals or mixtures of chemicals, additional synonyms, CAS numbers, and risk codes to alert the user, which may be of most concern for user protection.
The Trade Name Table contains 13 generic materials listings and 30 proprietary composition materials vs. a test battery of 21 chemicals. The Trade Name Table includes several multilayers of generic materials not included in the Master Chemical Resistance Table.
The color-coded recommendations in the Master Chemical Resistance Table still contain 27 representative barrier materials. However, one glove material and one suit material have been replaced by two new products, that is, Kemblok® and Chemprotex® 300. We believe these barrier listings include a wide range of gloves and suits on the market today.
We hope that this revised and updated edition will receive the same enthusiastic response as the prior editions. The purpose is to arm supervisors, industrial hygiene and safety professionals; hazardous materials spill responders, and others with sufficient knowledge and insight in selecting and using the right CPC. Selecting the most appropriate CPC can be an effective and efficient action preventing illnesses and injuries from hazardous chemical exposure where other control methods are not feasible.

The intent of the Quick Selection Guide to Chemical Protective Clothing is to assist workers, supervisors, safety and health professionals, spill responders, industrial hygienists, and others in the initial selection of protective clothing materials against specific chemical challenges on the job. This is accomplished by use of the color-coded tables, which summarize the chemical breakthrough performance of 27 common barrier materials against approximately 1000 chemicals organized in 98 chemical classes based on functional groups and 10 categories of multicomponent/commercial chemicals.
The three-step process in this guide completes the selection of barriers offering the best chemical resistance (see Figure 1).
First, the chemical name or synonym is found in the alphabetically sorted chemical index. The second step is to use the chemical class number, which appears to the left of the chemical name to search the selection recommendations tables. The master chemical resistance table is in numerical order by the chemical class. The final step is to find the chemical within the class listing and note the color-coded recommendations by barrier material. For example, to find the recommendations for protection from acetaldehyde, the user must first find the chemical class number in the Chemical Index. We find the chemical acetaldehyde listed second in the chemical index in Section III. This listing shows a class number of 121. This is the chemical class for aldehydes (aliphatic and alicyclic) under the ASTM F-1186, Standard Classification System for Chemicals According to Functional Groups. This listing also shows the chemical abstract service (CAS) number assigned to acetaldehyde as 75-07-0. The main purpose for listing the unique CAS number is to be sure that this chemical is the one that we are interested in and not another chemical by a similar name. The next column lists the “Risk Code” for hazard ratings. For acetaldehyde, it is listed as an “X.” This means that the chemical has received a designation of “harmful” to skin. The next step is to go to the selection recommendations tables in Section IV and find chemical class number 121 in the master chemical resistance table. Acetaldehyde is listed first within this group. Reading the color codes from left to right, we find, for example, butyl rubber as the recommended barrier (color-coded green) with “>8” representing greater than eight-hours resistance to acetaldehyde.
This three-step process is your fast track to the barrier offering the best chemical resistance against a chemical of interest. The full process from assessment of hazards to disposal of the protective clothing is described in Section II. In Section II, you will also find the concept of “Penetration, Degradation, and Permeation” described.
You have to be aware that skin is a significant route of chemical entry into the body, which may promote cancer or genetic damage. Chemical exposure also relates to skin irritation, burns, and sensitization. Hazards from chemical exposure are described in Section III.
Hazards are not limited to different types of chemical exposure. In the selection of the most appropriate protective clothing, biological and thermal exposure may be assessed as well.
