Even more rarely, there are sometimes trace amounts of latex found in nitrile gloves, which causes a latex allergy that is falsely attributed to the nitrile glove. If possible, opt for less toxic formulations and brands to limit toluene exposure. Such monitoring may be accomplished by collecting urine at the end of the exposure period and analyzing it for certain metabolites of DMF. Organotropic carcinogenic effects of 65 different N-nitroso compounds on BD rats. Assistant Surgeon General DMF is a potent liver toxin.

The symptoms vary widely and mild episodes may involve skin flushing, itching, or tingling with hives that have blanched or white centers. Toxicology 26:207-212. A solvent effect on the mutagenicity of tryptophan-pyrolysate mutagens in the salmonella/mammalian microscope assay. Disposable nitrile, natural latex, and vinyl gloves, often referred to as thin-mil gloves, are used in a variety of distinct applications. NIOSH [1983]. PHN: Apply up to four patches for 60 minutes. Training. The reports described above suggest an increase in cancer among workers exposed to DMF, but the evidence is not conclusive at this time. These innovative latex-free gloves provide the feel and elasticity you expect from latex, but without the challenging side effects. Standard single-use gloves provide a non-permeable barrier that safely protects workers’ hands in light duty work environments. Hepatic tumors and other chronic changes in rats following a single administration of aflatoxin. Respirators may be required by workers in certain situations such as emergencies and maintenance operations. The embryotoxic and teratogenic effects of dimethylformamide (translated). [1988] recently investigated a fabric-coating plant and found workers exposed to DMF (and other solvents) in poorly ventilated areas without appropriate skin protection. Threshold limit values and biological exposure indices for 1989- 1990. 33. Studies on acetamides and formamides for embryotoxic and teratogenic activities in the rabbit (translated). Nitrile is perfect for demanding applications, especially cleaning and dishwashing. A recommended standard for occupational exposure to acrylonitrile. Scailteur V, Lauwerys RR [1987]. However, DMF is known to have induced malformation in the offspring of mice [Scheufler and Freye 1975] and rabbits [Merkle and Zeller 1980].

Employers should use appropriate engineering controls to ensure that exposure to DMF in the workplace does not exceed the current NIOSH REL or OSHA PEL of 10 ppm as an 8-hr TWA [29 CFR 1910.1000; NIOSH 1988]. Lyon, France: World Health Organization, International Agency for Research on Cancer. CDC [1988]. Hazard Awareness. This chemical is easily absorbed through the skin and can cause liver damage and other adverse health effects. Wearing goggles and neoprene or nitrile gloves can lessen the chances of toluene coming into contact with the skin and eyes. Cincinnati, OH: U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, DHHS (NIOSH) Publication No. J Urol 136:834-836. The OSHA has suggested substituting water-based paints, adhesives, and cleaners in lieu of those made with toluene. Some reports also suggest an increase in cancer among workers exposed to DMF, but the evidence is not conclusive at this time. Cs Hyg 24(9):432-436. The National Institute for Occupational Safety and Health (NIOSH) estimates that more than 100,000 workers may be exposed to DMF in the United States [NIOSH 1983]. Koudela K, Spazier K [1981]. Although tobacco use alone can cause cancer of the mouth or throat, it is not known whether exposure to DMF might increase this risk by increasing absorption of carcinogens such as those present in tobacco (DMF is known to increase the absorption of some substances [Reiss 1966]). These men were exposed to a number of chemicals, including DMF, by inhalation of spray aerosols and by skin contact as they leaned over a conveyer belt to spread dye mixtures. Compared to latex gloves which many people complain of being allergic to, nitrile has no allergic side effect. Pros and Cons of Thick vs Thin Disposable Gloves Cincinnati, OH: U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, DHHS (NIOSH) Publication No. Testicular cancer in leather workers–Fulton County, New York.

DMF is also known to cause skin problems and alcohol intolerance. Currently, there is only one producer of DMF in the United States; annual production is between 50 and 60 million pounds [Porta 1988]. 1967; Carnaghan 1967; Herold 1969]. Hand pain, at the base of the thumb on the palm side of the hand, can be the result of wearing ambidextrous gloves, which force the thumb into a non-neutral position. The reproductive effects of DMF in humans have not been adequately studied. ACGIH [1989]. On the basis of the information outlined in this Alert, NIOSH concludes the following: NIOSH recommends the following measures to reduce exposure to DMF in the workplace. NIOSH [1990a]. Limitations of Use: The safety and efficacy have not been established for the treatment of … Biological surveillance of workers exposed to dimethylformamide and the influence of skin protection on its percutaneous absorption. NBR (nitrile butadiene rubber) is used in many different products – aeronautical application, footwear, any kind of molded goods, adhesives, sealants, sponges, foam, and also, of course, gloves. Disadvantages Although it isn’t as likely as with latex or rubber gloves, there is a slight risk of an allergic reaction to nitrile. Effects of dimethylformamide on human peripheral lymphocytes. Table 1 lists the types of respiratory protection recommended for DMF under various exposure conditions. Diseases caused by dimethylformamide. Therefore, the excess cancer observed could have resulted from exposure to one of these agents or to a combination of them; or the cancers could have been due to chance alone. Toxicological investigations on dimethylformamide. These exposure limits are based on the acute effects of DMF (primarily injury to the liver). CDC twenty four seven.
