POTENTIAL HEALTH EFFECTS:
EMERGENCY OVERVIEW:
KEVLAR(R) FIBER IS A GOLDEN YARN, STAPLE, FLOCK, PULP, OR FABRIC.
AS-SHIPPED THESE PRODUCTS POSE NO IMMEDIATE HAZARD. PROCESSING AND
HANDLING CAN PRODUCE AIRBORNE RESPIRABLE FIBRILS (SUBFIBERS). ANIMAL
STUDIES INDICATE THAT PROLONGED OVEREXPOSURE TO SUCH FIBRILS HAS THE
POTENTIAL FOR LASTING LUNG DAMAGE. USE VENTILATION OR A RESPIRATOR TO
MINIMIZE FIBRIL INHALATION.
DO NOT TOUCH MOVING THREADLINES OF KEVLAR(R) FIBER.
ENTANGLEMENT WITH THIS HIGH STRENGTH FIBER CAN SEVERELY CUT OR EVEN SEVER
FINGERS.
DURING A FIRE, THESE KEVLAR(R) PRODUCTS ARE UNLIKELY TO POSE A RESPIRABLE
FIBRIL HAZARD, BUT MAY RELEASE TOXIC AND IRRITATING GASES, MUCH LIKE THOSE
OF WOOL. KEVLAR(R) WILL BURN ONLY WITH ADDED HEAT, BUT PULP AND DUST MAY
SMOLDER. KEVLAR(R) PULP AND DUST DO NOT PRESENT AN EXPLOSION HAZARD.
IF PERMITTED TO DRY, PULP CAN BECOME ELECTROSTATICALLY CHARGED DURING
PROCESSING AND HANDLING.
ELECTROSTATIC DISCHARGE MAY CAUSE IGNITION OF NEARBY FLAMMABLE VAPORS.
IF PACKAGE IS OPENED, OR PUNCTURED, RE-MOISTURIZE PULP TO AT LEAST 4%
MOISTURE BEFORE USING.
KEVLAR(R) FIBERS ARE NONBIODEGRADABLE AND NONTOXIC TO AQUATIC LIFE; THEY
POSE NO UNUSUAL ENVIRONMENTAL HAZARD IN A SPILL OR FIRE.
POTENTIAL HEALTH EFFECTS:
EYE: FIBER FLY AND DUST MAY CAUSE SLIGHT MECHANICAL IRRITATION.
SKIN:
CONTINUAL RUBBING OF FIBERS AND FIBER PIECES ON THE SKIN (AS WHEN TRAPPED
UNDER CUFFS OR COLLAR, OR WHEN CONSTANTLY HANDLING FABRICS) MAY CAUSE
IRRITATION. BASED ON ANIMAL TESTS, THE FIBERS DO NOT CAUSE SENSITIZATION
(ALLERGIC REACTION).
INGESTION: BASED ON ANIMAL STUDIES, KEVLAR(R) IS NONTOXIC WHEN EATEN.
INHALATION:
KEVLAR(R) FIBER IS 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.
CHRONIC EFFECTS:
PROCESSING KEVLAR(R) OR MACHINING MATERIALS CONTAINING KEVLAR(R), MAY
CREATE FIBER DUST IN THE AIR SMALL ENOUGH TO BE BREATHED INTO THE LUNGS.
BASED ON ANIMAL TESTS, BREATHING THIS DUST AT VERY HIGH CONCENTRATIONS
REPEATEDLY OVER LONG PERIODS OF TIME MAY CAUSE LUNG INJURY (FIBROSIS).
CANCER:
IARC CLASSIFIED p-ARAMID 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. (SEE THE TOXICOLOGY SECTION AND
REFERENCES CONTAINED IN THE "OTHER INFORMATION" SECTION OF THIS MSDS.)
CARCINOGENICITY INFORMATION:
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.
| FIRST AID MEASURES | |
FIRST AID:
EYE CONTACT:
IN CASE OF CONTACT, IMMEDIATELY FLUSH EYES WITH PLENTY OF WATER FOR AT
LEAST 15 MINUTES. CALL A PHYSICIAN, IF IRRITATION PERSISTS OR DEVELOPS
LATER
INHALATION:
IF LARGE AMOUNTS OF FUMES, DUST OR FIBERS ARE INHALED, REMOVE TO FRESH AIR.
IF BREATHING IS DIFFICULT, GIVE OXYGEN AND CALL A PHYSICIAN. IF
PERSISTENT COUGH OR OTHER SYMPTOMS DEVELOP, GET MEDICAL ATTENTION.
SKIN CONTACT:
IF FIBERS IRRITATE THE SKIN, WASH WITH SOAP AND WATER. WASH CONTAMINATED
CLOTHING BEFORE REUSE. USE HAND CREAMS TO SOOTHE AND MOISTEN IRRITATED
SKIN. GET MEDICAL ATTENTION IF IRRITATION. PERSISTS AFTER CONTACT STOPS.
INGESTION:
NOT A PROBABLE ROUTE. HOWEVER, IN CASE OF GASTRO-INTESTINAL DISTRESS
FOLLOWING ACCIDENTAL INGESTION, CALL A PHYSICIAN.
| FIRE FIGHTING MEASURES | |
FLAMMABLE PROPERTIES:
FLASH POINT: NOT APPLICABLE
AUTO-IGNITION: NOT APPLICABLE
EXPLOSIVE LIMITS: NOT APPLICABLE
KEVLAR(R) FIBER IS INHERENTLY FLAME RESISTANT, BUT CAN BE IGNITED
(LIMITING OXYGEN INDEX = 29).
BURNING NORMALLY STOPS WHEN THE IGNITION SOURCE IS REMOVED.
PULP AND DUST ACCUMULATIONS MAY CONTINUE TO SMOLDER ONCE IGNITED.
KEVLAR(R) FIBER DUST DOES NOT PRESENT AN EXPLOSION HAZARD.
FIRE AND EXPLOSION HAZARDS:
BURNING KEVLAR(R) PRODUCES HAZARDOUS GASES SIMILAR TO THOSE FROM WOOL.
THESE ARE MOSTLY CARBON DIOXIDE, NITROGEN OXIDES AND SMALL AMOUNTS OF
HYDROGEN CYANIDE, AMMONIA, ALDEHYDES, ALIPHATIC HYDROCARBONS AND OTHER
TOXIC GASES, DEPENDING ON CONDITIONS OF BURNING.
CAUTION:
IF PERMITTED TO DRY, PULP CAN BECOME ELECTROSTATICALLY CHARGED DURING
PROCESSING AND HANDLING.
ELECTROSTATIC DISCHARGE MAY CAUSE IGNITION OF NEARBY FLAMMABLE VAPORS.
CLOSE PACKAGE TIGHTLY AFTER OPENING TO RETAIN MOISTURE. IF PACKAGE IS
OPENED OR PUNCTURED, RE-MOISTURIZE PULP TO AT LEAST 4% MOISTURE BEFORE
USING.
EXTINGUISHING MEDIA: WATER, FOAM, DRY CHEMICAL, CO2.
FIRE FIGHTING INSTRUCTIONS:
WEAR SELF-CONTAINED BREATHING APPARATUS.
KEEP PERSONNEL REMOVED AND UPWIND OF FIRE.
WEAR FULL PROTECTIVE EQUIPMENT (FULL BUNKER GEAR).
| ACCIDENTAL RELEASE MEASURES | |
SAFEGUARDS (PERSONNEL):
NOTE:
REVIEW FIRE FIGHTING MEASURES AND HANDLING (PERSONNEL) SECTIONS BEFORE
PROCEEDING WITH CLEAN-UP. USE APPROPRIATE PERSONAL PROTECTIVE EQUIPMENT
DURING CLEAN-UP.
SPILL CLEAN UP:
WASH, SHOVEL OR MOP UP AND PLACE IN SOLID WASTE CONTAINERS.
FIBER IS NOT BIODEGRADABLE; DO NOT FLUSH TO DRAINS.
CLEAN UP DUSTS AND PULP WITH HIGH EFFICIENCY PARTICULATE AIR (HEPA)
FILTERED VACUUM EQUIPMENT, OR BY WET CLEANING. AVOID THE USE OF DRY
SWEEPING OR AIR JET BLOWING OF FIBERS AND DUST, WHICH CAN RE-SUSPEND
RESPIRABLE DUST IN THE AIR.
| HANDLING AND STORAGE | |
HANDLING (PERSONNEL):
DO NOT TOUCH MOVING THREADLINES OF KEVLAR(R) FIBER.
ENTANGLEMENT WITH THIS HIGH STRENGTH FIBER CAN SEVERELY CUT OR EVEN SEVER
FINGERS.
STORAGE:
KEVLAR(R) IS DEGRADED BY ULTRAVIOLET LIGHT. DO NOT STORE IN DIRECT
SUNLIGHT. FLUORESCENT LIGHTING WILL CAUSE DISCOLORATION, BUT WILL NOT
AFFECT FIBER MECHANICAL PROPERTIES.
DRY AND WET KEVLAR(R) PULP IS PACKAGED IN MOISTURE-PROOF BAG OR BALES TO
PREVENT DRYING TO LESS THAN 4% MOISTURE AND POSSIBLE PICK-UP OF
ELECTROSTATIC CHARGE. IF PACKAGE IS PUNCTURED, RE-MOISTURIZE PULP TO AT
LEAST 4% MOISTURE BEFORE USING.
| EXPOSURE CONTROLS/PERSONAL PROTECTION | |
ENGINEERING CONTROLS: GENERALLY APPLICABLE CONTROL MEASURES AND PRECAUTION
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.
ENGINEERING CONTROLS:
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 AND 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 AIR FLOWS 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
FIBRILS MAY BE GENERATED, RECIRCULATED AIR SHOULD BE PERIODICALLY MEASURED
TO DETERMINE IF THEY 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.
FUMES AND SMOKE FROM LASER CUTTING OR MACHINING OF FABRICS AND COMPOSITES
OF KEVLAR(R) SHOULD BE WELL EXHAUSTED OR REMOVED BY VENTILATION.
WATER JET CUTTING OF FABRIC OR COMPOSITES OF KEVLAR(R) PRODUCES RESPIRABLE
SIZE FIBRILS IN THE CUTTING WASTE. IF DRIED, THIS WASTE CAN BECOME A SOURCE
OF AIRBORNE RESPIRABLE FIBERS. RINSE OR WIPE WASTE FROM FLOORS, WORK
SURFACES AND PARTS BEFORE IT DRIES.
PERSONAL PROTECTIVE EQUIPMENT:
RESPIRATION PROTECTION:
RESPIRATOR USE MUST BE IN ACCORDANCE WITH OSHA STANDARD 29 CFR 1910.134
(THE "RESPIRATOR STANDARD").
WHERE AIRBORNE DUST AND FIBRIL CONCENTRATIONS ARE EXPECTED TO EXCEED
APPLICABLE EXPOSURE LIMITS, OR WHERE THERE IS POTENTIAL FOR IRRITATION OF
THE NASAL PASSAGE 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 USED UNDER CIRCUMSTANCES MEETING THE RESPIRATOR STANDARD.
DISPOSABLE DUST MASKS EQUIVALENT TO 3M MODEL N95 8210 OR EQUIVALENT MAY
ALSO BE USED.
EYE PROTECTION:
WEAR SAFETY GLASSES OR COVERALL GOGGLES WHEN CUTTING OR MECHANICALLY
WORKING THIS PRODUCT, OR WHERE AIRBORNE DUST AND FLY IS PRESENT.
SKIN PROTECTION:
WHEN REPEATED FORCEFUL CONTACT WITH KEVLAR(R) FIBER STRUCTURES IS
ANTICIPATED, WEAR PROTECTIVE GLOVES AND SLEEVES TO MINIMIZE SKIN ABRASION
AND DRYING.
IF REPEATED HANDLING OF KEVLAR(R) LEADS TO DRY SKIN, USE NON-GREASY
MOISTURIZING SKIN CREAM. (BARRIER CREAMS ARE NOT RECOMMENDED, AS THEY MAY
ACTUALLY CAUSE FIBER DUST TO STICK TO THE SKIN.)

| TOXICOLOGICAL INFORMATION | |
ANIMAL DATA:
EYE EFFECTS:
KEVLAR(R) IS UNTESTED FOR EYE IRRITANCY. AS WITH OTHER PARTICLES,
MECHANICAL ACTION OF FIBERS IN THE EYE MAY CAUSE SLIGHT IRRITATION.
SKIN EFFECTS:
KEVLAR(R) FIBER IS NOT A SKIN IRRITANT, OR A SKIN SENSITIZER IN ANIMALS.
NONE OF THREE TESTS USING GUINEA PIGS PRODUCED SENSITIZATION.
SKIN SENSITIZATION HAS NOT BEEN OBSERVED IN HUMAN PATCH TESTS OR IN
INDUSTRIAL EXPERIENCED. (KEVLAR(R) FIBER HAS 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 KEVLAR(R) 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.
ACUTE ORAL EFFECTS:
KEVLAR(R) POLYMER HAS VERY LOW TOXICITY BY INGESTION.
ORAL ALD: >7500 MG/KG IN RATS.
ACUTE INHALATION EFFECTS:
INDUSTRIAL EXPERIENCE SHOWS THAT INHALATION OF KEVLAR(R) FIBROUS DUST AND
FLY MAY CAUSE MECHANICAL IRRITATION OF THE MUCOUS MEMBRANES OF THE NOSE AND
THROAT; THESE SYMPTOMS DISAPPEAR UPON CESSATION OF EXPOSURE.
SUBCHRONIC INHALATION EFFECTS:
IN A TWO WEEK INHALATION STUDY WITH RATS (1983), RESPIRABLE KEVLAR(R)
FIBRILS (SUBFIBERS) 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 PERMANENT LUNG EFFECTS AT CONCENTRATIONS
OF 280 F/CC OR LESS.
TWO-WEEK HIGH-DOSE AEROSOL EXPOSURES TO p-ARAMID FIBRILS IN RATS AND
HAMSTERS PRODUCED TRANSIENT PULMONARY INFLAMMATORY AND CELL PROLIFERATIVE
RESPONSES, ALONG WITH EVIDENCE OF PROGRESSIVE FIBER BIODEGRADABILITY
WITH INCREASING RESIDENCE TIME IN LUNG TISSUES OF EXPOSED ANIMALS. IN BOTH
STUDIES, THE LUNGS OF ANIMALS WERE ANALYZED AT SEVERAL POST-EXPOSURE TIME
PERIODS RANGING FROM IMMEDIATELY AFTER EXPOSURE THROUGH ONE YEAR
POST-EXPOSURE. LUNG TISSUE THICKENING LESIONS IN RATS, WHICH WERE MEASURED
MORPHOMETRICALLY IMMEDIATELY AFTER A 2-WEEK EXPOSURE, HAD PEAKED AT 1 MONTH
POST-EXPOSURE AND WERE REVERSIBLE AT 6 AND 12 MONTHS POST-EXPOSURE, I.E.,
NO EVIDENCE OF PULMONARY LESIONS COULD BE FOUND 6 MONTHS AFTER EXPOSURE.
CHRONIC INHALATION EFFECTS:
A TWO-YEAR INHALATION STUDY WITH KEVLAR(R) PULP (REFINED TO INCREASE ITS
RESPIRABLE FIBRIL CONTENT) PRODUCED PULMONARY FIBROSIS AT CONCENTRATIONS OF
25, 100, AND 400 F/CC, AS WELL AS ADDITIONAL LUNG LESIONS. A PANEL OF 12
PATHOLOGISTS FROM NORTH AMERICA AND EUROPE REVIEWED THE 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
NON-SPECIFIC BIOLOGICAL RESPONSE TO THE RESPIRABLE MATERIAL, RATHER THAN AN
INDICATION OF THE TOXICITY OF KEVLAR(R). 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 2.5
TO 400 F/CC HAVE SHOWN THAT KEVLAR(R) 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 DU PONT IN HAMSTERS.
IN-VITRO TESTS SHOW KEVLAR(R) FIBRILS 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.
CARCINOGENICITY:
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).
SUMMARY:
INDUSTRIAL MONITORING OF AIRBORNE FIBRIL CONCENTRATIONS INDICATE IT WOULD
BE UNLIKELY THAT HUMAN EXPOSURES WOULD APPROACH LEVELS THAT CAUSED
PERMANENT HEALTH EFFECTS IN ANIMALS STUDIES. HOWEVER, BASED ON ANIMAL
STUDIES, LONG TERM EXPOSURES TO HIGH DOSES OF RESPIRABLE FIBERS COULD
LEAD TO PULMONARY INFLAMMATION AND SUBSEQUENT DEVELOPMENT OF CHRONIC LUNG
DISEASE.
MUTAGENIC, DEVELOPMENTAL AND REPRODUCTIVE EFFECTS:
IN AN IN VITRO ASSAY, KEVLAR(R) FIBRILS PRODUCED NO CHROMOSOMAL ABERRATIONS
IN CULTURED HUMAN PERIPHERAL BLOOD LYMPHOCYTES.
NO ANIMAL TESTS HAVE BEEN RUN TO DEFINE MUTAGENIC, DEVELOPMENTAL OR
REPRODUCTIVE HAZARDS.
| ECOLOGICAL INFORMATION | |
ECOTOXICOLOGICAL INFORMATION:
KEVLAR(R) FIBERS ARE ESSENTIALLY NON-BIODEGRADABLE IN THE ENVIRONMENT, AND
DO NOT LEACH MATERIAL TOXIC TO FLORA OR FAUNA.
FINISHES AND ADDITIVES USED WITH KEVLAR(R) ARE ROUTINELY TESTED FOR THEIR
POTENTIAL EFFECTS ON MANUFACTURING WASTEWATER TREATMENT SYSTEMS.
BIOCOMPATIBILITY AND AQUATIC TOXICITY TESTS GIVE THE FOLLOWING RESULTS:
* FINISHES DO NOT APPEAR TO BE INHIBITORY OR TOXIC TO MICROBES COMMONLY
FOUND IN BIOLOGICAL TREATMENT SYSTEMS.
BIODEGRADATION AND NORMAL ANTI-FOAM TREATMENTS SHOULD CONTROL FOAMING.
* DISCHARGE OF SCOURED FINISHES SHOULD NOT RESULT IN INCREASED EFFLUENT
TOXICITY.
* MOST FINISHES ARE SUBSTANTIALLY OR COMPLETELY BIODEGRADABLE, BUT A FEW
ARE NOT.
SINCE CONCENTRATIONS AND TREATMENT CONDITIONS VARY, THE ABOVE SHOULD BE
CONSIDERED INDICATIVE ONLY.
| DISPOSAL CONSIDERATIONS | |
WASTE DISPOSAL:
KEVLAR(R) FIBER IS NOT A HAZARDOUS WASTE AS DEFINED BY REGULATIONS
IMPLEMENTING THE RESOURCE CONSERVATION AND RECOVERY ACT (RCRA). IN
GENERAL, WASTE MATERIALS OF KEVLAR(R) 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
MATERIAL.
WASTE SUCH AS WATERJET CUTTER SLUDGE OR DUST FROM AIR FILTERS MAY BE
ENRICHED IN RESPIRABLE FIBERS. BAG SECURELY, LABEL AS CONTAINING RESPIRABLE
FIBERS, AND DISPOSE OF IT AS NON-HAZARDOUS INDUSTRIAL WASTE.
SINCE THE FIBER IS ESSENTIALLY NON-BIODEGRADABLE IT SHOULD NOT BE FLUSHED
TO SURFACE WATERS OR SANITARY SEWER SYSTEMS.
