3. HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
Non-flammable black rubbery material. As supplied, release of ingredients
is not expected as ingredients are bound in a polymer matrix. Repeated
or prolonged skin contact may cause allergic skin reactions in workers
sensitive to nitrile rubber. Hot product may cause thermal burns. Irritating
dusts and fumes may be produced during vulcanization or other
processing operations. Equipment malfunction or overheating can
produce toxic fumes that can be harmful or fatal. Use adequate ventilation
in processing areas.
POTENTIAL HEALTH EFFECTS
EYE: None known for solid material. Hot product may cause thermal burns. Fumes released during normal processing
may cause irritation.
SKIN: Repeated contact may cause irritation and redness in workers allergic to rubber. Hot product may cause thermal
burns.
INHALATION: Inadequate ventilation during processing operations may result in inhalation of fumes that may produce
irritation, chest tightness, shortness of breath, nausea, dizziness, and headaches. Equipment malfunction or overheating
may produce significant amounts of harmful fumes (See Section 11).
CHRONIC: Epidemiologic studies among rubber products workers has noted excess deaths from various cancers.
CARCINOGENICITY: IARC: Yes NTP: Yes OSHA: Yes
IARC lists the rubber industry as an exposure circumstance that "entails exposures that are carcinogenic to humans". Fillers
in this product contain small amounts of quartz, an ingredient classified as a confirmed human carcinogen by IARC and NTP
and regulated under 29 CFR 1910.1200 by OSHA. This product also contains carbon black, a substance that has caused
cancer in experimental animals and is classified as "possibly carcinogenic to humans" (Group 2B) by IARC. These
ingredients are bound, and release is not expected under normal conditions.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Irritant properties of processing fumes may aggravate pre-
existing eye, skin, and respiratory conditions.
SIGNS AND SYMPTOMS: Processing fumes may cause eye and respiratory irritation.
TARGET ORGANS: Eyes, skin, respiratory system (processing fumes)
4. FIRST AID MEASURES
EYE CONTACT: If irritation occurs, flush eyes with lukewarm water for 15 minutes. If irritation persists, get medical
attention. If heated rubber comes in contact with the eyes, get immediate medical attention.
SKIN: Remove contaminated clothing and wash skin thoroughly with soap and water. If irritation persists, seek medical
attention. If skin comes in contact with heated rubber, immediately immerse the affected area in cold water and obtain
medical attention. DO NOT attempt to remove product as damaged skin may tear easily.
INHALATION: Acute exposure is not anticipated. If fumes from heated product are inhaled, immediately remove to fresh
air. If breathing problems occur, administer oxygen or artificial respiration as indicated. All symptoms should be treated as
potentially harmful. Get immediate medical attention.
OTHER: Not expected. Major ingredients are not highly toxic; however, no data is available for polymerized rubber.
Consult a physician.

5. FIRE FIGHTING MEASURES
FLAMMABLE PROPERTIES
FLASH POINT: Non-Flammable
LEL: No Data UEL: No data
FLAMMABLE LIMITS:
NFPA HAZARD CLASSIFICATION:
HEALTH: 1 FLAMMABILITY: 1 INSTABILITY: 0
EXTINGUISHING MEDIA: Water, dry chemical, or dry air foam. Carbon dioxide may be unsuitable as the lack of cooling
capacity may result in reignition.
FIRE AND EXPLOSION HAZARDS: Not flammable but may be difficult to extinguish once ignited. Direct water stream on
molten material may spatter or spread fire. Release of significant quantities of fine powders or dusts from this product may
cause a dust explosion. Fire may produce irritating, toxic, and flammable decomposition products that may include various
hydrocarbons, hydrogen cyanide, sulfur oxides, nitrogen oxides, ammonia, carbon oxides, and other oxidation products.
FIRE FIGHTING INSTRUCTIONS: Firefighters should wear a NIOSH-approved, full-facepiece self-contained breathing
apparatus (SCBA) operated in positive pressure mode and full turnout or bunker gear with additional chemical protective
clothing as necessary to protect against thermal decomposition products.
6. ACCIDENTAL RELEASE MEASURES
Solid material does not require special control measures. Sweep, shovel, or otherwise recover and place in closed
containers for later reuse or disposal. If spillage occurs during processing, isolate hazard area and wait for material to cool
before recovering. Processing fume condensates that form on ductwork, exhaust hoods and other surfaces are combustible
and may contain toxic components that can be absorbed through the skin. Prevent skin contact with condensates.
Periodically remove condensates to prevent accumulation. Wear appropriate personal protective equipment (See Section
8).
7. HANDLING AND STORAGE
Store below 70 癋 away from direct sources of heat and sunlight. Provide adequate ventilation during processing Equipment
malfunction, increasing processing temperature or other improper procedures may result in the formation of irritating, toxic,
or flammable decomposition products. Do not heat rubber without adequate control measures. Use proper handling
procedures for any ingredients added to this product.
DO NOT eat, drink, smoke, or apply cosmetics in work areas. DO NOT store personal items in work areas. Wash hands
before eating, drinking, smoking, and breaks. Processing equipment may contain decomposition residues that can cause
poisoning from ingestion, skin contact, or inhalation. DO NOT USE PROCESSING EQUIPMENT TO HEAT FOOD.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
RESPIRATORY PROTECTION: Under normal working conditions below acceptable exposure guidelines, none required.
Respiratory protection is dependent upon conditions and magnitude of exposure. Select NIOSH-approved respirators in
accordance with 29 CFR 1910.134.
SKIN PROTECTION: Protective gloves. Wear gloves with thermal protection when processing.
EYE PROTECTION: Safety glasses or goggles are recommended. Wear full-facepiece supplied air respirator for fumes.
ENGINEERING CONTROLS: General ventilation. Use local exhaust ventilation and enclosed processes as necessary to
control processing dusts and fumes when heating.

11. TOXICOLOGICAL INFORMATION
INHALATION: Processing fumes may cause irritation. Equipment failure and overheating may cause partial
decomposition. The composition of the fumes released is determined by the conditions. Cyanides emitted by neoprene
rubber decomposition are toxic and may adversely affect the central nervous system, lungs, and thyroid.
SKIN: Sensitive individuals may develop dermatitis with repeated contact. Cyanide compounds that may be produced from
decomposition are toxic if absorbed through the skin.
EYE: Processing fumes may cause irritation.
CHRONIC: Rubber contains carbon black and small amounts of quartz. Although release of these ingredients is not
expected, repeated inhalation of carbon black and quartz over time can cause lung disease and increase the risks of
developing cancer.
Chronic ingestion of Di(2-ethylhexyl)adipate has resulted in hepatocellular carcinomas female mice and hepatocellular
adenomas in male mice but not in rats. Skin application of 1,2-dihydro-2,2,4-trimethylquinoline resin has caused liver
damage in rats.
