Description of above components:
NOMEX® fiber products are of two forms, staple and continuous filament. NOMEX® staple is of three categories, (1) 100% NOMEX®, (2) NOMEX® - KEVLAR® blends with up to 60 % KEVLAR® and (3) NOMEX® /KEVLAR® blends with anti-static fibers. NOMEX® fiber is composed principally of a solid organic polymer (meta-aramid) composed of carbon, oxygen, nitrogen and hydrogen. The fiber contains moisture depending upon storage and use conditions, a small amount of residual dimethylacetamide (DMAc) from the manufacturing process and surface coatings of lubricating and anti-static finishes. Additives designed to enhance specific product performance such as coloring agents, ultra-violet light blockers, etc. are contained in the fiber structure and do not present any known hazardous exposure in handling or use.
Many NOMEX® staple products contain KEVLAR® fiber. KEVLAR®, is composed of a solid organic polymer (para-aramid) made of carbon, oxygen, nitrogen and hydrogen.
Anti-static fibers are sheath-core fibers. The ultra-thin conductive core is carbon black enclosed in polyethylene membrane. The protective sheath is nylon. The anti-static fiber is blended with NOMEX® at such low levels that normal textile processing is not significantly affected.
3. HAZARDS IDENTIFICATION
Based on over 30 years of experience in commercial use and extensive toxicological testing, NOMEX® fiber products present minimal risk to human health and the environment.
NOMEX® fiber is a creamy white yarn, staple, or floc that may be blended with similar forms of gold-colored KEVLAR® brand fiber. As-shipped these products pose no immediate hazard. Processing and handling can produce airborne respirable KEVLAR® fibrils (subfibers.) Animal studies indicate that prolonged overexposure to such fibrils has the potential to cause lasting lung damage. Use ventilation or a respirator to minimize fibril inhalation.
During a fire, NOMEX® fiber products are unlikely to release many respirable fibers, but may release toxic and irritating gases, much like wool. KEVLAR® and NOMEX® will burn only with added heat, but dust may smolder. Dusts of KEVLAR® and NOMEX® do not present an explosion hazard.
NOMEX® aramid fibers of 2 denier per filament contain 0-2% dimethylacetamide (DMAc.) Heavier fibers may contain up to 3% DMAc. Processing and handling may result in exposure via skin absorption and inhalation. Prolonged and repeated overexposure to DMAc can cause liver damage. Wash hands after handling. Avoid exposure to hot processing in confined spaces. Use adequate ventilation. Industrial experience shows that minimal absorption of DMAc occurs from room temperature handling of NOMEX®. DMAc can be released by heating above 200C or by extracting with liquids, especially during dyeing.
NOMEX® and KEVLAR® fibers are non-biodegradable and non-toxic to aquatic life; they pose no unusual environmental hazard in a spill or fire.
POTENTIAL HEALTH EFFECTS:
Fiber fly and dust may cause slight mechanical irritation. NOMEX® and KEVLAR® are untested for eye irritancy.
Based on animal and human skin patch tests, neither KEVLAR® nor NOMEX® cause sensitization (allergic reaction) and have little potential for skin irritation. Continual rubbing of fibers and fiber pieces on the skin (as when trapped under cuffs or collar, or when constantly handled as fabrics) may cause skin irritation.
Based on animal studies, NOMEX® and KEVLAR® are nontoxic when eaten.
NOMEX® and KEVLAR® fibers are too big to inhale into the lungs, but fiber dust and fly from processing may be breathed into the nose and throat. Working unprotected in dusty conditions may cause upper respiratory irritation and cold-like symptoms.
Processing NOMEX® containing KEVLAR® may create KEVLAR® fibrous dust in the air small enough be breathed into the lungs. Based on animal tests, breathing KEVLAR® fibrous dust at very high concentrations repeatedly over a long time may cause lung injury (fibrosis.) Long term animal tests of NOMEX® dust instilled into the lungs produced no lung damage.
At room temperature DMAc does not normally come out of the fiber. When NOMEX® fiber products are processed at elevated temperatures, the residual DMAc may be volatilized and accumulate in poorly ventilated areas. Washing, scouring, dyeing, or other operations that expose the NOMEX® products to solutions and liquids may extract the residual DMAc into the processing solutions and liquids. DMAc is rapidly absorbed through the skin and can be harmful if inhaled or absorbed in sufficient amounts. Animal studies have shown high levels of DMAc exposure can cause liver, kidney and retinal damage and eye and skin irritation.
None of the components present in this material at concentrations equal to or greater than 0.1% are listed by IARC, NTP, OSHA or ACGIH as a carcinogen. Carbon black is listed by IARC as 2B -- possible human carcinogen.
No cancer was produced in rats held two years after NOMEX® dust was instilled into their lungs.
IARC classed p-aramid (KEVLAR®) respirable fibrils as Group 3, "not classifiable as to carcinogenicity in humans," in October, 1996. That is, after reviewing all published toxicological literature on p-aramid, they found no convincing evidence of carcinogenicity.
NOMEX® may contain up to 5% anti-static fibers (carbon core sheathed with nylon.)
The wearing of garments containing anti-static NOMEX® minimizes the possibility of sparking due to fabric-to-fabric rubbing. Grounded footwear and flooring and other safety procedures and precautions must still be used in flammable atmospheres.
Based on animal studies, none of the anti-static fiber components present a significant health hazard.

4. First Aid Measures
If large amounts of fumes, dust or fibers are inhaled, remove to fresh air. If persistent cough or other symptoms develop, get medical attention. If exposed to excessive levels of DMAc, remove to fresh air and get medical attention if symptoms persist.
Wash with soap and water. Wash contaminated clothing and gloves before reuse. Use hand creams to soothe and moisten irritated skin. Get medical attention if irritation persists after contact stops.
In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Get medical attention if irritation persists or develops later.
Not a probable route. However, in case of gastro-intestinal distress following accidental ingestion, call a physician.
5. Fire Fighting Measures
Flash point: Not applicable
Explosive limits: Not applicable
Auto-ignition temperature: Not available
NOMEX® fiber is inherently flame resistant, but can be ignited
(Limiting Oxygen Index = 28.)
Burning normally stops when the ignition source is removed.
Dust accumulations may continue to smolder if once ignited.
NOMEX® and KEVLAR® fiber dusts do not present an explosion hazard.
FIRE AND EXPLOSION HAZARDS
Burning NOMEX® and KEVLAR® produce hazardous gases similar to those from wool.
These are mostly carbon monoxide, carbon dioxide, nitrogen oxides and small amounts of hydrogen cyanide, ammonia, aldehydes, aliphatic hydrocarbons and other toxic gases depending on conditions of burning.
Use water, foam, carbon dioxide (CO2) or dry chemical.
FIRE FIGHTING INSTRUCTIONS
Keep personnel removed and upwind of fire.
Wear self-contained breathing apparatus.
Wear full protective equipment (full Bunker gear.)
6. Accidental release measures
NOTE: Review FIRE FIGHTING MEASURES and HANDLING sections before proceeding with cleanup.
Use appropriate PERSONAL PROTECTIVE EQUIPMENT during cleanup.
Wash, shovel or mop up fibers and place in solid waste containers. Avoid the use of dry sweeping or air jet blowing of fibers and dust; these can re-suspend respirable dust in the air.
Clean up dusts containing KEVLAR® fibrils with high efficiency particulate air (HEPA) filtered vacuum equipment, by wiping, or by wet cleaning.
Fiber is not biodegradable; do not flush to drains.
7. handling and storage
Do not touch moving threadlines of NOMEX® and KEVLAR®. Entanglement with this high strength yarn can severely cut, or even sever fingers.
NOMEX® and KEVLAR® are degraded by ultraviolet light. Do not store in direct sunlight. Fluorescent lighting will cause discoloration, but will not affect fiber mechanical properties.
8. exposure controls, personal protection
GENERALLY APPLICABLE CONTROL MEASURES AND PRECAUTIONS
Use only with adequate ventilation. Avoid dust generation. Do not consume food, drink or tobacco in areas where they may become contaminated with this material.
If fumes, fiber fly or dusts are generated, use engineering controls (where technically feasible) whenever necessary to control exposures below applicable limits. Isolation, enclosures, exhausts, ventilation, wetting and dust collection systems may be used.
If ventilation and exhaust air is recirculated, it should be filtered and conditioned to eliminate respirable fibers, dust and fumes. While HEPA filters are effective for dust removal from local exhausts, they have high pressure drops and require frequent maintenance. Larger airflow can be effectively cleaned of non-respirable fibers and particles by screens and coarse filter media. However, respirable particles can be removed only by secondary filtration equipment designed for fine particles (less than 10 micrometers aerodynamic diameter) or water curtains. Where respirable dust may be generated, recirculated air should be periodically monitored to determine if fibrils are being adequately removed. Air monitoring should be done using the standard asbestos test method, NIOSH 7400 (B). Method 7400(A) can also be used, counting only fibers less than 3 micrometers in diameter.
Processes that heat NOMEX® fibers may release DMAc vapors to the air. Use un-recirculated ventilation to remove DMAc from the air when using such processes.
During dyeing with carriers, the DMAc in NOMEX® fibers is extracted to the bath. Dye baths should be dumped through closed piping directly to closed sewers or water treatment systems. Normal precautions to reduce exposure to organic carriers should be sufficient, since the amount of DMAc is small compared to the carrier.
Fumes and smoke from laser cutting or machining of fabrics of NOMEX® should be well exhausted or removed by ventilation.
PERSONAL PROTECTIVE EQUIPMENT (PPE)
Where airborne dust and fibril concentrations are expected to exceed applicable exposure limits, or where there is potential for irritation of the nasal passages by the mechanical action of the fibers, NIOSH-approved respirators should be used.
An air-purifying respirator with a dust/mist/fume cartridge or canister may be permissible under certain circumstances.
Disposable dust masks (3M model N95 8210, or equivalent) may also be used.
When NOMEX® is used at elevated temperatures, or in a way that might create airborne DMAc or decomposition products in excess of applicable exposure limits, wear NIOSH-approved organic vapor cartridge respirators.
Wear safety glasses with side-shields.

10. stability and reactivity
Stable at normal temperatures and storage conditions.
CONDITIONS TO AVOID:
See Decomposition, below.
Heating NOMEX® fiber above about 200°C (392°F) will rapidly drive out the DMAc (0-3% by weight in un-dyed fibers.) This will not harm the fiber, but the DMAc vapors may present an inhalation hazard in confined spaces.
INCOMPATIBILITY WITH OTHER MATERIALS:
None are reasonably foreseeable.
HAZARDOUS DECOMPOSITION PRODUCTS:
NOMEX® polymer begins to thermally degrade rapidly above 300°C (572°F). Fiber finishes can thermally decompose above 200°C (392°F). The thermal degradation rate increases with temperature. Decomposition can produce irritating and toxic gases.
Polymerization will not occur.
11. toxicological information
NOMEX® and KEVLAR® are untested for eye irritancy. As with other particles, mechanical action of fibers in the eye may cause slight irritation.
DMAc is an eye irritant in animals and man.* Eye contact may include eye irritation with discomfort, tearing, or blurring of vision.
NOMEX® and KEVLAR® brand fibers are not skin irritants, or skin sensitizers in animals.
None of three tests using guinea pigs produced sensitization (KEVLAR®.)
Skin sensitization has not been observed in human patch tests or in industrial experience. NOMEX® and KEVLAR® fiber have been used in direct contact with the skin in industrial gloves and protective apparel for many years.
The mechanical action of the fibers may cause slight skin irritation at clothing binding points. Repeated harsh rubbing of the skin with fibrous dust or supported fiber structures (e.g., sized, coated or impregnated fabrics, paper edges, etc.) may cause abrasion, with resulting irritation and rash. Symptoms disappear following cessation of skin contact.
DMAc skin absorption toxicity: LD50 for rabbits is 2240mg/kg (moderately toxic by skin absorption.) DMAc is a skin irritant, but not a skin sensitizer in animals. In humans, skin contact can cause irritation with discomfort or rash.
ACUTE ORAL EFFECTS:
NOMEX® and KEVLAR® have very low toxicity by ingestion.
Oral ALD >7500mg/kg in rats.
DMAc is slightly toxic by ingestion.
LD50 is 4930mg/kg in female rats.
ACUTE INHALATION EFFECTS:
Industrial experience shows that inhalation of fibrous dust and fly may cause mechanical irritation of the mucous membranes of the nose and throat with resulting dry cough, scratchy throat and runny nose. Symptoms cease upon cessation of exposure.
DMAc skin absorption toxicity: ALD for rabbits, when applied in single doses, is 5000mg/kg body weight.
Human health effects of overexposure to DMAc by inhalation or skin absorption may initially include nonspecific discomfort such as nausea, headache, or weakness; temporary nervous headache, confusion, loss of coordination and loss of consciousness; abnormal liver and kidney functions as detected by laboratory tests or jaundice (liver). Skin permeation occurs rapidly and can occur in amounts capable of producing the effects of systemic toxicity. There are no reports of human sensitization. Individuals with pre-existing diseases of the liver may have increased susceptibility to the toxicity of excessive exposure.
SUBCHRONIC INHALATION EFFECTS:
In a two week inhalation study with rats (1983), respirable fibrils (subfibers) of KEVLAR® at concentrations of 1000-2000 fibrils per cubic centimeter (f/cc) caused mild non-progressive fibrosis (lung scarring that shrinks with cessation of exposure) and nonspecific effects such as weight loss, and irritation. There were no effects at concentrations of 280f/cc or less.
A two-week subchronic test in which mice were exposed to DMAc via inhalation showed liver and testicular effects at high exposure concentrations (300, 500 and 700ppm.) No adverse effects were observed at 100ppm.
CHRONIC INHALATION EFFECTS:
NOMEX® and KEVLAR® Fibers:
NOMEX® fiber does not break down into fibrils when abraded, instead it produces non-fibrous particles. A 2.5mg dust sample of NOMEX®, prepared by grinding NOMEX® paper, was instilled once into rat lungs. Tissue response was measured histopathologically in groups of rats at periodic sacrifices from 2 days to 2 years. No sign of adverse response to the NOMEX® dust was seen.
A two year inhalation study with KEVLAR® pulp (refined to increase its respirable fibril content) showed fibrosis at concentrations of 25, 100, and 400 f/cc, and lung lesions in some rats in the group exposed to respirable fibers at concentrations of 100 and 400 f/cc. A panel of 12 pathologists from North America and Europe reviewed these lesions and diagnosed them as "proliferative keratin cysts." They agreed that the lesions are not malignant neoplasms and are most likely not neoplastic. This unique lesion is not found in humans and may be indicative of a nonspecific biological response to the respirable material, rather than an indication of the toxicity of KEVLAR®. No fibrosis was seen in animals exposed to 2.5 f/cc for two years (and very little at 25f/cc.) At no concentrations were fibers found to have migrated beyond the lungs and associated lymph system. Four experiments at fibril concentrations of 2.5f/cc to 400f/cc have shown that KEVLAR® fibrils in the lungs of rats are shortened with time, probably by enzymatic clipping of the polymer chain. (This effect has been independently confirmed in rats by two other laboratories and by DuPont in hamsters. In-vitro tests show fibrils of KEVLAR® are shortened in proteolytic enzyme solutions.) While not all fibrils disappear, long fibers are cut to an average of less than 5 micrometers and gradually removed. The lower the exposure, the faster fibrils are broken down.
IARC (International Agency for Research on Cancer, the cancer research arm of the United Nations World Health Organization,) completed an in-depth review of all valid scientific data relating to para-aramid fibrils in October, 1996. They classified the fibrils as in Group 3, "not classifiable as to their carcinogenicity to humans." That is, the experts found no convincing evidence of carcinogenicity. (While IARC has no regulatory authority, its expert opinions are used for guidance by regulatory authorities worldwide.)
Toxic effects described in animals from exposure by inhalation, ingestion or skin contact include retinal, liver, lung and kidney effects, reduced spermatogenesis, bone marrow effects and ataxia. Tests in animals demonstrate no carcinogenic activity.
If there is significant potential for skin contact with DMAc, biological monitoring should be done to measure the level of DMAc metabolites in urine specimens collected at the end of the shift. It is DuPont practice to limit individual end-of-shift DMAc metabolites in urine levels to 40ppm or below, expressed as N-methylacetamide (MMAc) and to control average DMAc metabolite in urine levels for the job to 20ppm or below, expressed as MMAc.
MUTAGENIC, DEVELOPMENTAL AND REPRODUCTIVE EFFECTS:
In an in vitro assay, fibrils of KEVLAR® produced no chromosomal aberrations in cultured human peripheral blood lymphocytes.
No animal tests have been run to define mutagenic, developmental or reproductive hazards of either NOMEX® or KEVLAR® fibers.
Tests in mammalian cell cultures demonstrate no mutagenic activity. In laboratory tests, application of DMAc to the skin of pregnant rats has caused fetal deaths when the doses were close to the lethal dose level for the mother. Embryonal malformations have been observed at dose levels 20% of the lethal dose and higher. However, when male and female rats were exposed to mean concentrations of DMAc at 31ppm, 101ppm, and 291 ppm for 6 hours per day over several weeks, no reproductive effects were observed.
12. ECOLOGICAL INFORMATION
NOMEX® and KEVLAR® fiber are essentially non-biodegradable in the environment, and do not leach material toxic to flora or fauna.
Finishes and additives used with NOMEX® are routinely tested for their potential effects on manufacturing wastewater treatment systems. Biocompatibility and aquatic toxicity tests give the following results:
None appear to be inhibitory or toxic to microbes commonly found in biological treatment
Biodegradation and normal anti-foam treatments control foaming.
Discharge of scoured finishes should not result in increased effluent toxicities.
Finishes are completely or substantially biodegradable.
Since concentrations and treatment conditions vary, the above should be considered indicative only.
13. disposal considerations
NOMEX® and KEVLAR® fibers are not hazardous wastes as defined by regulations implementing the Resource Conservation and Recovery Act (RCRA). In general, waste materials of NOMEX® and KEVLAR® may be treated, stored, transported and disposed of in accordance with the state and local regulations governing the disposal of other common or non-RCRA regulated waste materials.
Waste such as air-washer sludge or dust from air filters may be enriched in respirable fibrils of KEVLAR®. Bag securely, label as containing respirable fibers, and dispose as non-hazardous industrial waste.
Since the fiber is essentially non-biodegradable, do not flush to surface water or sanitary sewer system.
DMAc in wastewater streams contributes to the Biological Oxygen Demand (BOD), but is readily biodegradable in conventional biological sewage treatment systems. Wastewater containing DMAc is not a RCRA hazardous waste. Wastewater containing DMAc should be disposed of in accordance with state and local regulations for wastewater discharges.
