2 HAZARDS IDENTIFICATION
Emergency Overview
Physical State: Solid rubber
Color: Black
Odor: No data available.
CAUTION!
Prolonged or repeated contact may dry skin and cause irritation. May cause adverse reproductive effects -
such as birth defects, miscarriages, or infertility based on animal data. Possible cancer hazard - may cause
cancer based on animal data. Rubber compounds generally do not pose a health hazard unless heated.
Under normal conditions of processing and use, exposure to the chemical constituents in this product is
unlikely. All ingredients are tightly bound in a polymeric matrix that has a negligible vapor pressure so
there is a low potential for inhalation or ingestion of ingredients. Skin (dermal) contact is possible.
Potential Health Effects
Inhalation: Grinding and sanding this product may generate dust. Dust may irritate throat and respiratory
system and cause coughing. Lower concentrations of fumes from burning this material may cause
respiratory irritation with coughing, difficulty in breathing, or shortness of breath. High concentrations
may cause severe irritation, pulmonary edema (body fluid in the lungs) with coughing, wheezing, and
abnormal lung sounds. Symptoms may progress to severe shortness of breath, central nervous system
effects, and collapse. Symptoms may be delayed and progressively worsen.
Eye Contact: Grinding and sanding this product may generate dust. Dust may irritate the eyes.
Decomposition products may cause eye irritation. Contact with hot material can cause thermal burns which
may result in permanent damage.
Skin Contact: Prolonged or repeated skin contact may cause irritation. Individuals sensitive to small
amounts of curing agents present may develop a rash (dermatitis). Contact with hot material can cause

Chloroprene (Neoprene) Rubber 'Final' 29-June-2006
thermal burns which may result in permanent damage.
Ingestion: No adverse effects due to ingestion are expected.
Chronic Health Effects: Repeated exposure may cause skin dryness or cracking. Danger of adverse
health effects by prolonged exposure. May impair fertility. Possible human cancer hazard. Carbon black
has caused cancer in experimental animals. These ingredients are bound within the rubber and release is not
expected.
Target Organ(s): | Reproductive system | Skin |
Potential Physical / Chemical Effects: This product is not flammable.

4 FIRST AID MEASURES
General: For contact with hot polymer: Flush eyes with lukewarm water for at least 15 minutes.
Immerse skin in cool water. DO NOT attempt to remove polymer from skin as this can cause further
damage. Get immediate medical attention. Prompt medical attention is required if decomposition products
are inhaled.
Inhalation: If fumes from heated product are inhaled: Move into fresh air and keep at rest. Move the
exposed person to fresh air at once. For breathing difficulties oxygen may be necessary. If breathing stops,
provide artificial respiration. Consult a physician for specific advice.
Eye Contact: Dust in the eyes: Flush eyes thoroughly with water, taking care to rinse under eyelids. If
irritation persists, continue flushing for 15 minutes, rinsing from time to time under eyelids. If discomfort
continues, consult a physician.
Skin Contact: Remove contaminated clothing immediately and wash skin with soap and water. If

irritation occurs, get medical assistance.
Ingestion: Rinse mouth thoroughly. Drink plenty of water. Get medical attention if symptoms occur.
5 FIRE-FIGHTING MEASURES
Extinguishing Media: This product is not flammable. Use fire-extinguishing media appropriate for
surrounding materials.
Unsuitable Extinguishing Media: Not applicable.
Special Fire Fighting Procedures: Use standard firefighting procedures and consider the hazards of other
involved materials.
Unusual Fire & Explosion Hazards: The product is non-combustible. If heated, toxic vapors may be
formed. Burning this material, or exposing it to temperatures above 300 癈 may result in the release of
irritating fumes.
Hazardous Combustion Products: Alcohols, Aldehydes, Carbon Dioxide, Carbon Monoxide,
Hydrocarbons, Hydrogen Chloride
Protective Measures: Self contained breathing apparatus and full protective clothing must be worn in case

Engineering Controls: Provide adequate ventilation. If dust or fumes are generated during use, use local
exhaust in combination with general ventilation as necessary to remove fumes/dust from the workers'
breathing zone and to ensure exposures do not exceed applicable limits.
Respiratory Protection: No protection is ordinarily required under normal conditions of use and with
adequate ventilation. During dust-raising work or inhalation of hot/molten material: Use a
NIOSH-approved respirator (See 29 CRF 1910.134, respiratory protection standard).
Eye Protection: If contact with hot material may occur, safety glasses and face shield are recommended.
Hand Protection: Wear suitable gloves. When material is heated, wear gloves to protect against thermal
burns.
Skin Protection: It is a good industrial hygiene practice to minimize skin contact. Thermally protective,
chemical resistant apron and long sleeves are recommended when volume of hot material is significant.
Hygiene Measures: Always observe good personal hygiene measures, such as washing after handling the
material and before eating, drinking, and/or smoking. Routinely wash work clothing and protective
equipment to remove contaminants.

Listed Carcinogens: The rubber industry is listed as an exposure circumstance that is known to be
carcinogenic to humans (Group 1). Carbon black: Certain carbon blacks have proved carcinogenic in
animal studies. Inhalation animal studies of high concentrations resulted in chronic inflammation, lung
fibrosis and lung tumors. Epidemiology studies of workers include findings of bronchitis, pneumonia,
emphysema and excess cancer. Substances bound in a polymer or other matrix should present little or no
hazard.

Product Information
Other Acute: The principal components used in this product have been reacted and are no longer present
in their original form. The finished polymerized product is an inert polyacrylic rubber, and exposure to the
original constituents would not be expected under normal conditions. Like most high-molecular weight
polymers, this product is not known to exhibit any adverse acute or chronic health effects. Burning this
material or exposing it to temperatures in excess of 300 癈 can generate irritating and toxic fumes. The type
of compounds generated depends upon temperature and conditions. Health effects from these fumes can
range from transient to severe eye, skin and respiratory rritation, pulmonary edema, headache, nausea,
drowsiness as well as a variety of other effects. Some decomposition products are toxic if absorbed through
the skin in sufficient quantities. Grinding and sanding this product may generate dust. Dusts may irritate
the respiratory tract, skin and eyes. Repeated exposure to high concentrations of dust may adversely affect
the lungs. Dust inhalation can also inhibit the clearance of toxic particles from the lung by decreasing the
mobility of alveolar macrophages.
Chronic Toxicity: Repeated exposure may cause skin dryness or cracking. May impair fertility. Possible
cancer hazard - may cause cancer based on animal data.
