Excerpt:
Acetic acid (glacial or concentrated solutions): nitrile gloves (incidental contact); neoprene or butyl rubber gloves are recommended if contact with acetic acid above 10% is probable for an extended period of time.
Acetic anhydride: double glove with heavier weight (8 mil) nitrile gloves (incidental contact) Acetic anhydride is very corrosive to human tissues (skin, eyes, mucus membranes) and a poison by inhalation. For handling larger quantities of pure material only heavier weight (.28-.33 mm) butyl rubber or neoprene gloves are recommended.
Acetone: heavier weight (8 mil) natural rubber (incidental contact); for extended contact with acetone the only recommended glove type is butyl rubber.
If you are cleaning parts with acetone, or have any other use of acetone where there is more than incidental contact, you must use butyl rubber gloves. Natural rubber gloves have about a 10 minute breakthrough time and are for incidental contact only. Nitrile gloves have a less than four minute breakthrough time and are not recommended for any use of acetone.
Acetonitrile: nitrile gloves or double glove with nitrile gloves (incidental contact)
For transfer of acetonitrile or for large scale use, only heavier weight butyl rubber or poplyvinyl acetate gloves are recommended. Acetonitrile permeates though disposable latex exam gloves in a matter of seconds and latex gloves should never be used to handle this material.
Acrylamide: nitrile gloves or double glove with nitrile gloves (incidental contact); butyl rubber gloves are recommended for extended contact (such as repackaging pure acrylamide into smaller containers)
Acrylamide is readily absorbed through unbroken skin. Acrylamide is a carcinogen, mutagen, teratogen and a potent neurotoxin with no known antidote, so adequate hand protection is essential when using this chemical. Note that once acrylamide solutions are polymerized the resulting gels are no longer hazardous and, assuming that they are not contaminated with other hazardous materials, they may be disposed of in the ordinary trash.
Note: See Heavy Metal Salts for proper disposal of gloves and other dry waste contaminated with acrylamide.
bis- Acrylamide: nitrile gloves
bis- Acrylamide (N,N’-dihydroxy-ethylene-bis-acrylamide) does not share the more
extreme toxic characteristics of acrylamide. However, its toxicological properties have not been fully investigated and it should be treated as a hazardous material.
Alkali metals (lithium, sodium, potassium, rubidium, cesium): nitrile gloves
Note: It is very important that all work with alkali metals be conducted in the absence of water. Water forms hydrogen gas on contact with alkali metals. As this is a very exothermic reaction, working with alkali metals presents a severe fire hazard. All labs working with alkali metals must have a Class D fire extinguisher available.
Ammonium hydroxide: nitrile gloves; for extended contact heavier weight neoprene or butyl rubber gloves are superior to nitrile gloves
Benzotriazole, 1,2,3-: nitrile gloves
Butanol (and isomers): nitrile gloves (incidental contact); for extended contact, heavier weight butyl rubber or nitrile gloves are recommended
Butyric acid: nitrile gloves (incidental contact); butyl rubber or neoprene gloves are recommended if contact with butyric acid is probable for an extended period of time.
Carbon disulfide: double glove with heavier weight (8 mil) nitrile gloves (incidental contact) or use 15 mil or heavier nitrile gloves; remove outer glove at once if exposed to carbon disulfide
Most nitrile gloves have a breakthrough time of only 8 to 20 minutes and thus offer little protection when exposed to carbon disulfide. For operations involving the use of larger amounts of carbon disulfide, when transferring carbon disulfide from one container to another or for other potentially extended contact, the only gloves recommended are viton and polyvinyl acetate (PVA).
Carbon tetrachloride: double glove with heavier weight (8 mil) nitrile gloves (incidental contact) or use 15 mil or heavier nitrile gloves; remove outer glove at once if exposed to carbon tetrachloride
Most nitrile gloves have a breakthrough time of only a few minutes and thus offer little protection when exposed to carbon tetrachloride. For operations involving the use of larger amounts of carbon tetrachloride, when transferring carbon tetrachloride from one container to another or for other potentially extended contact, the only gloves recommended are viton. Viton gloves are expensive, but they are the standard glove to use with carbon tetrachloride.
Carbon tetrachloride is a poison, carcinogen, mutagen and teratogen. It is readily absorbed through unbroken skin. Alcohol and acetone are known to enhance the toxicity of carbon tetrachloride. The dose required to cause poisoning in humans varies significantly, with the ingestion of as little as 2 ml. having caused death. Carbon tetrachloride is also a substantial ozone depleting chemical and its use has been banned commercially. If you can find a substitute for carbon tetrachloride, it is strongly recommended that you use an alternative material.
Catechol: nitrile gloves
Chloroform: double glove with heavier weight (8 mil) nitrile gloves (incidental contact) or use 15 mil or heavier nitrile gloves; remove outer glove at once if exposed to chloroform
Thin (3-4 mil) Nitrile gloves have a 4 minute breakthrough time and thus offer little protection when exposed to chloroform. For operations involving the use of larger amounts of chloroform, such as transferring chloroform from one container to another or for large-scale extractions, etc., the only gloves recommended are viton or polyvinyl acetate (PVA). Viton gloves are expensive, but they are the standard glove to use with chloroform.
Chlorosulfuron: nitrile gloves
Cobalt chloride: See Heavy Metal Salts.
Copper (cupric) sulfate: nitrile gloves
Cryogenic liquids (liquid nitrogen, argon, helium, etc.): Cryogenic materials handling-rated gloves. Cryo-Gloves®, made by Tempshield, Inc., are highly recommended. Note that these gloves are made for handling very cold objects, but that they are not for immersion in liquid nitrogen or other extended contact with cryogenic liquids.
3,3'-Diaminobenzidine (DAB): nitrile gloves (incidental contact); double glove with nitrile gloves when handling the pure material or concentrated stock solutions
Note: See Heavy Metal Salts for proper disposal of gloves and other dry waste contaminated with DBA.
Diazomethane in ether (a derivatizing reagent): double glove with heavier weight (8 mil) nitrile gloves (incidental contact) or use 15 mil or heavier nitrile gloves; remove outer glove at once if exposed to diazomethane in ether.
For possible extended contact, such as when transferring diazomethane in ether or when making reagent solutions containing this material, the only recommended glove would be a Norfoil glove, due to the extreme hazards associated with this material. Diazomethane is an extreme poison, a cancer suspect agent, extremely flammable, easily detonated and has an autoignition temperature of 100° C. (an ordinary light bulb would cause a sufficient quantity of the vapor in air to autodetonate). This is easily one of the most dangerous materials in use in labs at Cornell. If there is any way you can substitute another material for diazomethane in ether it is strongly recommended that you do so.
Dichloromethane: See Methylene Chloride.
2,4-Dichlorophenoxy acetic acid (2,4-D): nitrile gloves
Diethyl pyrocarbonate: nitrile gloves (incidental contact); double glove with nitrile gloves when handling the pure material or concentrated stock solutions
Dimethyl sulfoxide (DMSO): heavier weight natural rubber gloves (15-18 mil; not 4 mil latex exam gloves) (incidental contact); butyl rubber gloves are recommended for extended contact; if you are allergic to natural latex products you may double glove with heavier weight (8 mil) disposable nitrile gloves (incidental contact) or use 15 mil or heavier nitrile gloves; remove outer glove at once if exposed to DMSO.
Nitrile gloves are not recommended for use with DMSO if extended contact with the hands is expected. Some brands of nitrile gloves have degradation times of five minutes when used with DMSO. DMSO freely penetrates the skin and may carry dissolved chemicals with it into the body, so hand protection is especially important if you are working with any hazardous materials dissolved in DMSO.
1,4-Dioxane (dioxane): double glove with heavier weight (8 mil) nitrile gloves (incidental contact) or use 15 mil or heavier nitrile gloves; remove outer glove at once if exposed to dioxane
Most nitrile gloves have a breakthrough time of only a few minutes and thus offer little protection when exposed to dioxane. For operations involving the use of larger amounts of dioxane, when transferring dioxane from one container to another or for other potentially extended contact, the only gloves recommended are butyl rubber gloves. Dioxane is one of the few commonly used lab chemicals that readily degrades viton gloves.
Dioxane is only moderately toxic, but it is a listed carcinogen, mutagen and teratogen. It is readily absorbed through unbroken skin so hand protection is especially important when working with this material.
Dithiothreitol (Cleland's Reagent): nitrile gloves
Ethanol: nitrile gloves
Ethidium bromide (EtBr): nitrile gloves (incidental contact); double glove with nitrile gloves when handling the pure material or concentrated stock solutions
Note: See Heavy Metal Salts for proper disposal of gloves and other dry waste contaminated with EtBr
Ethyl acetate: double glove with heavier weight (8 mil) nitrile gloves (incidental contact)
Nitrile gloves are not serviceable for extended contact as even heavy weight nitrile gloves (36 mil) have a breakthrough time of only 8 minutes and thus offer little protection when exposed to ethyl acetate. For operations involving the use of larger amounts of ethyl acetate, when transferring ethyl acetate from one container to another or for other potentially extended contact, the only gloves recommended are butyl rubber and polyvinyl acetate (PVA).
Ethyl ether (diethyl ether, ether): double glove with heavier weight (8 mil) nitrile gloves (incidental contact) or use 15 mil or heavier nitrile gloves; remove outer glove at once if exposed to ether
Ether is one of those chemicals that attacks almost all known commonly used glove materials.
It permeates through viton, butyl rubber, neoprene, nitrile and natural rubber in a matter of minutes. The only recommended glove material for extended contact is polyvinyl acetate (PVA), such as the PVA™ brand made by Ansell Edmont.
Formaldehyde: nitrile gloves
Formamide: nitrile gloves (incidental contact); butyl rubber gloves are the only gloves recommended for direct contact with the pure material.
Formamide is often used in the pure form. If you use pure formamide in a procedure where there is probable contact with the skin, it is strongly recommended that you wear butyl rubber gloves.
Formic acid: double glove with heavier weight (8 mil) nitrile gloves (incidental contact) Formic acid is very corrosive to human tissues (skin, eyes, mucus membranes). For handling larger quantities of pure material only heavier weight (.28-.33 mm) butyl rubber or neoprene gloves are recommended.
Gallic acid: nitrile gloves
Geneticin: nitrile gloves
Glutaraldehyde: nitrile gloves
Heavy metal salts (especially those that are easily soluble in water): nitrile gloves or double glove in some cases*
For most inorganic (ionic) salts of heavy metals the human skin is usually an effective barrier against absorption of the heavy metal ions. If there are cracks in the skin, areas of inflammation, insect bites, cuts or other breaches of the integrity of the skin, heavy metal ions may be passed directly through the skin. The salts of many heavy metals are toxic or highly toxic and rated as poisons: arsenic, bismuth, cadmium, chromium, cobalt, lead, mercury, nickel, osmium, silver and uranium. Some of these materials are also listed as corrosives (chromium trioxide), inhalation hazards (osmium tetroxide), known or suspect carcinogens and mutagens (lead and lead salts, mercury and its salts, etc.) or radioactive (uranium). Disposable nitrile gloves are generally acceptable for the use of the pure salts and stock (concentrated) or dilute solutions for the common salts of the above metals (acetates, chlorides, sulfates, nitrates, anhydrides, oxides, hydroxides, etc.) where only incidental contact will be made with these materials or their solutions.
Several heavy metal salts are more easily absorbed by the skin than others. Osmium tetroxide is readily absorbed by the skin and is very toxic. Lead acetate is absorbed 1-1/2 times more easily than other lead salts.
Mercuric chloride can be absorbed fairly easily, especially if there are cracks, cuts or other breaks in the skin. It is also very toxic. It is recommended to *double glove* with nitrile gloves when using these materials, especially when handing the pure compounds or their strong solutions.
It is important that used gloves, and other dry materials, contaminated with heavy metals are not disposed of in the ordinary trash. Place all heavy metal contaminated gloves in a separate waste stream (container). The College of Veterinary Medicine maintains a Medical Waste Program. Gloves (and other dry waste items) contaminated with trace amounts of heavy metals may be sent to the Vet College for disposal. EH&S can furnish the guidelines provided by the Vet College or you may contact Dr. Larry Thompson at 253-3966 or Denver Metzler at 253-3288 for information on this program. It is important that the materials being disposed of are clearly identified on the Medical Waste Tracking Tag you will be required to complete as part of the disposal process, such as "Trace contaminated with lead acetate." (Note that this method of disposal is also acceptable for trace contaminated gloves and other dry waste generated from the use of carcinogens, mutagens and other materials that can not be disposed of in the ordinary trash.) Uncontaminated or decontaminated gloves may be disposed of as ordinary trash.
Heptane: double glove with heavier weight (8 mil) nitrile gloves (incidental contact) or use 15 mil or heavier nitrile gloves
For extended contact, as when using heptane for large scale extractions, refilling secondary containers or as a cleaning fluid, a heavier weight nitrile (35 mils or thicker), viton or PVA gloves are recommended. Note that the permeation time for heptane through 4 mil nitrile gloves is about 8 minutes and through latex exam gloves is even less time; subsequently, these gloves are not recommended for use with heptane.
Hexamethylenediamine (1,6-diaminohexane): heavier weight (8 mil) nitrile gloves (incidental contact); use a heavier weight neoprene glove when handling the pure material or concentrated stock solutions (extended contact)
Hexane: double glove with heavier weight (8 mil) nitrile gloves (incidental contact) or use 15 mil or heavier nitrile gloves
For extended contact, as when using hexane for large scale extractions, refilling secondary containers or as a cleaning fluid, a heavier weight nitrile (35 mils or thicker), viton or PVA gloves are recommended. Note that the permeation time for hexane through 4 mil nitrile gloves is about 12 minutes and through latex exam gloves is only about 5-6 minutes; subsequently, these gloves are not recommended for use with hexane.
Hydrochloric acid (concentrated and strong solutions): nitrile gloves (incidental contact)
A heavier weight neoprene or butyl rubber glove would be superior for long-term use with more concentrated solutions, such as cleaning glassware that has been soaking in an HCl bath or other larger-scale use of HCl.
Hydrofluoric acid (HF): double glove with heavier weight (8 mil) nitrile gloves (incidental contact) or use 15 mil or heavier nitrile gloves
Note that additional protective equipment must always be worn when using larger quantities of HF. Nitrile or rubber sleeves, rubber aprons, face shields and splash goggles (not safety glasses) should also be worn. All users of HF must maintain an HF first aid kit in their lab.
HF users are advised to contact EH&S for an “HF Users Information Packet.”
Hypophosphorous acid: double glove with nitrile gloves (4 mil) (incidental contact) or use 8 mil or heavier nitrile gloves

Laser dyes: nitrile gloves
Lead acetate: See Heavy Metal Salts.
2-Mercaptoethanol:
Mercuric chloride: See Heavy Metal Salts.
Mercury: nitrile gloves
Methanol (methyl alcohol): nitrile gloves
Methanol should never be allowed to make contact with the skin, as it is fairly easily absorbed by the skin. Methanol is a poison.
Methylene chloride: double glove with heavier weight (8 mil) nitrile gloves (incidental contact)
Methylene chloride will permeate through thin (3-4 mil) nitrile gloves in four minutes or less. If you are double gloved, as recommended, and you splash or spill methylene chloride on your gloves, stop what you are doing and change the outer glove immediately. If you allow methylene chloride to remain on the outer nitrile glove for more than two to four minutes you must discard both sets of gloves and re-double glove. Methylene chloride permeates disposable latex exam gloves in a matter of seconds and latex gloves should never be used to handle this material.
For use of methylene chloride where contact with the glove is anticipated, such as stripping paint or gluing plastics, only polyvinyl acetate (PVA) or viton gloves are recommended. These gloves come in .28-.33 mm thickness. PVA offers the best protection.
Methylphosphonic acid: double glove with nitrile gloves (4 mil) (incidental contact) or use 8 mil or heavier nitrile gloves
Methyl sulfonic acid, ethyl ester (EMS) (ethyl methanesulfonate): nitrile gloves (incidental contact); double glove with nitrile gloves when handling the pure material or concentrated stock solutions
Note: See Heavy Metal Salts for proper disposal of gloves and other dry waste contaminated with EMS.
Monoethanolamine: nitrile gloves
Nickel chloride: See Heavy Metal Salts.
Nitric acid: double glove with heavier weight (8 mil) nitrile gloves (incidental contact); remove outer glove at once if exposed to nitric acid
Light weight nitrile gloves are not recommended for any use with nitric acid as they are degraded very quickly. Even heavier weight nitrile gloves last only five minutes or less in contact with nitric acid. For handling larger quantities of concentrated nitric acid, or for extended contact, only heavier weight (.28-.33 mm) butyl rubber or neoprene gloves are recommended.
N-Methylethanolamine: : double glove with heavier weight (8 mil) nitrile gloves (incidental contact); remove outer glove at once if exposed to N-methylethanolamine

Osmium tetroxide: See Heavy Metal Salts.
Paraformaldehyde: nitrile gloves
Pentane: double glove with heavier weight (8 mil) nitrile gloves (incidental contact)
Thin nitrile gloves are quickly degraded by pentane. For extended contact with pentane only heavier weight neoprene gloves or viton gloves are recommended.
Pesticides: heavier weight unlined nitrile gloves (8-20 mils) or a glove specified by the pesticide label.*
A wide variety of pesticides are in use at Cornell. Each EPA registered pesticide is provided with an MSDS-like label. The pesticide label may have a glove selection category listed on the it which is based on the “EPA Chemical Resistance Category Selection Chart.” The glove selection category is listed as A through H, with each category representing a group or class of pesticides.
The EPA glove selection chart is available on the Web at:
http://oeh.cals.cornell.edu/EPAChemRes.html (http://oeh.cals.cornell.edu/EPAChemRes.html)
If the label specifies a glove type, the applicator must wear the specified glove. Additional information on the selection of gloves for the use of various pesticides may be obtained from Mary-Lynn Cummings at 255-2557 or the Pesticide Management Education Program at 255-1866
Perchloroethylene (tetrachloroethylene): Double glove with heavier weight (8 mil) nitrile gloves (incidental contact); remove outer glove at once if exposed to perchloroethylene.
For extended contact, such as parts washing, heavier weight nitrile gloves (22 mil or heavier, such as Ansell Edmont Sol-Vex brand, #37-165) may last up to five hours.
Viton gloves are recommended for repeated extended contact with perchloroethylene.
Thin (4 mil) nitile gloves have a breakthrough time of 4 minutes or less.; neoprene and vinyl glove have a breakthrough time of less than 10 minutes; none of these materials are suitable for use with perchloroethylene.
Petroleum ether: nitrile gloves (incidental contact); or heavy weight nitrile or viton for extended contact.
Phenol: double glove with heavier weight (8 mil) nitrile gloves (incidental contact); neoprene or butyl rubber gloves are recommended for extensive use of phenol such as working with the pure material or making solutions.
Nitrile gloves have a 30-minute breakthrough time with phenol. If working with double gloved nitrile gloves, change the outer glove frequently if exposed to this material.
Phenol-chloroform mixtures: Double glove with heavier weight (8 mil) nitrile gloves (incidental contact) or use 15 mil or heavier nitrile gloves; remove outer glove at once if exposed to mixture.
Viton gloves are recommended for work with phenol-chloroform mixtures when probable exposure to the mixtures exists (extended contact), such as when making up the mixtures.
Phenylmethylsulfonyl fluoride (PMSF): nitrile gloves (incidental contact); double glove with nitrile gloves when handling the pure material or concentrated stock solutions
Phenylmethylsulfonyl fluoride is corrosive (causes burns) on contact with the skin, eyes and mucus membranes. It is also a highly toxic cholinesterase inhibitor and central nervous system poison. Avoid all contact.
Note: See Heavy Metal Salts for proper disposal of gloves and other dry waste contaminated with PMSF.
Phosphonic acid: double glove with nitrile gloves (4 mil) (incidental contact) or use 8 mil or heavier nitrile gloves
Phosphoric acid: double glove with nitrile gloves (4 mil) (incidental contact) or use 8 mil or heavier nitrile gloves
Picloram (4-amino-3,5,6-trichloropicolinic aicd): nitrile glove
Polychlorinated biphenyls (PCBs): For weighing out of pure or concentrated materials, wear an 8 mil or heavier nitrile glove over a neoprene glove. For dilute solutions in corn oil (1 p.p.m. or less) neoprene gloves (20 mil) are recommended.
Note: See Heavy Metal Salts for proper disposal of gloves and other dry waste contaminated with PCBs.
Polyoxyethylenesorbitan monolaurate (Tween 20): nitrile gloves
Potassium ferricyanide: nitrile gloves
Potassium ferrocyanide: nitrile gloves
Potassium permanganate: nitrile gloves
Propanol: nitrile gloves
Propionic acid: nitrile gloves (incidental contact); neoprene or butyl rubber gloves are recommended if contact with propionic acid is probable for an extended period of time.
Propylene oxide: heavier weight (17 mil or greater) butyl rubber or neoprene gloves (incidental contact); norfoil gloves are the only glove recommended for extended contact
Propylene oxide attacks almost all common glove materials. It passes directly through latex gloves and the breakthrough time for nitrile gloves ranges from seconds to a few minutes.
Ordinary 4 mil latex and nitrile lab gloves should never be used with this material. Propylene oxide has a breakthrough time of only 10 minutes with viton gloves which are completely resistant to most common lab chemicals. The breakthrough time for neoprene and butyl rubber gloves is on the order of 45-50 minutes. Use heavier weight gloves (17 mil or greater), check the gloves often and discard after 40 minutes or so or of continuous use when there is contact of propylene oxide with the glove. When possible, use a norfoil glove with a heavier weight (8 mil) nitrile
Psoralen: nitrile gloves (incidental contact); double glove with nitrile gloves when handling the pure material or concentrated stock solutions Psoralen is corrosive (causes burns) on contact with the skin, eyes and mucus membranes. It is anticipated to be a carcinogen, it is a mutagen and a strong photosensitizer. Avoid all contact.
Note: See Heavy Metal Salts for proper disposal of gloves and other dry waste contaminated with psoralen.
Pump oil: butyl rubber gloves
If you are changing pump oil or servicing pumps where contact with the oil may occur, the only recommended glove type is butyl rubber.
Silane based silanization or drivatization compounds: double glove with heavier weight (8 mil) nitrile gloves (incidental contact) or use 15 mil or heavier nitrile gloves; remove outer glove at once if signs of degradation occur
Silver nitrate: See Heavy Metal Salts.

Spermidine: nitrile gloves Sulfuric acid: heavier weight (8 mil) nitrile gloves (incidental contact); heavier weight (20 mil or greater) neoprene or butyl rubbber gloves (extended contact)
Sulfuric acid: heavier weight (8 mil) nitrile gloves (incidental contact); heavier weight (20 mil or greater) neoprene or butyl rubbber gloves (extended contact)
Tetrahydrofuran (THF): double glove with heavier weight (8 mil) nitrile gloves (incidental contact) or use 15 mil or heavier nitrile gloves; remove outer glove at once if THF contacts glove
For extended contact, such as when using THF for larger scale reactions, refilling secondary containers or as a cleaning fluid, only Norfoil gloves are recommended. Polyvinyl acetate (PVA) gives some limited protection (up to 1-1/2 hours for some gloves) but are inferior to the Norfoil gloves. Note that the permeation time for THF through 4 mil nitrile gloves and latex exam gloves is almost instantaneous; subsequently, these gloves are not recommended for use with THF.
3,3',5,5'-Tetramethylbenzidine (TMB): nitrile gloves (incidental contact); double glove with nitrile gloves when handling the pure material or concentrated stock solutions
Note: See Heavy Metal Salts for proper disposal of gloves and other dry waste contaminated with TMB.
N, N, N’, N’-Tetramethylethylenediamine (TEMED): nitrile gloves (incidental contact); double glove with nitrile gloves when handling the pure material or concentrated stock solutions TEMED is corrosive (causes burns) on contact with the skin, eyes and mucus membranes.
