2. Hazard(s) Identification
2.1 Classification of the substance or mixture. While this material is not considered hazardous according to the OSHA Hazard Communication Standard (29CFR 1910.1200), this SDS contains valuable information critical to the safe handling and proper use of the product. This SDS should be retained and available.
2.2 Label elements
Hazard statements and symbols/Precautionary statements: None
2.3 Other hazards
Acute: Fumes from hot work on or near polyurethane products can be irritating and lead to coughing. These fumes could contain traces of TDI, and/or MBOCA. Skin or airborne exposure to isocyanates may produce an asthma-like lung sensitization, with shortness of breath, wheezing or cough, which may occur after re-exposure to very low levels. Skin contact with some polyurethane products may result in skin sensitization or an asthma-like
lung sensitization. Chronic: Animal studies indicate that chronic inhalation or overexposure of dusts may cause inflammation of the lungs, fibrosis, and airway destruction.
Severe Immediate Hazards
Dusts from grinding operations may aggravate existing lung disorders when proper protection is not used.
OSHA Regulatory Status
POLYURETHANE ELASTOMERS ARE FULLY REACTED POLYMERS FORMING ARTICLES WHICH ARE NOT CONSIDERED HAZARDOUS UNDER OSHA’s CRITERIA 29 CFR 1910.1200. HOWEVER, HAZARDOUS DUSTS, VAPORS, GASES, OR FUMES MAY BE RELEASED BY MECHANICAL OR THERMAL PROCESSING, OR BY
3. Composition/Information on ingredients
Component Synonyms CAS# Concentration (wt%) Cast polyurethane n/a >99.9% 4,4’ methylene bis (2-chloroaniline) MBOCA or MOCA 104-14-4 <0.1%
4. First aid measures
4.1 Description of the first aid measures
Route of Exposure Instructions
Inhalation Move to an area free from the risk of further exposure. If not breathing, or breathing is difficult, obtain medical attention. Eye Contact If dust from grinding causes irritation, rinse with water immediately for 5
minutes. Seek medical attention if irritation persists. Skin Contact Wash exposed skin with soap and water. Ingestion Not a route of exposure.
4.2 Most important symptoms and effects, both acute and delayed
Delayed: Sensitizing effects possible from dusts/fumes
4.3 Indication of any immediate medical attention and special treatment needed. No antidotes known
5. Fire Fighting Measures
5.1 Extinguishing media
Suitable media includes carbon dioxide, dry chemical, foam, or water spray.
5.2 Special hazards arising from the substance or mixture
Toxic and/or irritating fumes can be produced during burning of this material.
Decomposition products may be hazardous (see section 10 for details on decomposition
5.3 Advice for Firefighters
Firefighters should wear self-contained breathing apparatus and full protective clothing.
Downwind personnel should be evacuated. Do not reseal contaminated containers as pressure buildup may rupture them.
6. Accidental Release Measures
6.1 Personal precautions, protective equipment, and emergency procedures
Evacuate personnel. Wear suitable PPE as described in section 8.
6.2 Environmental precautions
No environmental precautions required.
6.3 Methods and materials for containment and cleaning up. Pick up and handle as any other solid material.
7. Handling and Storage
7.1 Precautions for safe handling. None in normal use.
7.2 Conditions for safe storage, including anything that is incompatible. Store material at ambient temperature and pressure. Keep away from sources of flame, sparks, or other ignition sources. Material is stable under normal conditions.
7.3 Specific end use(s) No specific requirements needed
8. Exposure Controls/Personal Protection
8.1 Control parameters
Permissible Exposure Limits (PELS TLVs BEIs). There are no applicable exposure limits for cured polyurethane materials. There are limits for TDI and MDI which may be released under some heat processing activities.
The current OSHA Permissible Exposure Limit for both TDI and MDI is 0.02 ppm (Ceiling). A ceiling limit is not to be exceeded. The current American Conference of Governmental Industrial Hygienists (ACGIH). Threshold Limit Value (TLV)for TDI is 0.005 ppm for an 8 hour TWA, with a 15 minute Short Term Exposure Limit (STEL) of 0.02 ppm. TDI is also indicated as a “Sensitizer” by ACGIH. The 8 hour TLV for MDI is 0.005 PPM TWA. The TLV for TDI is under the 2006 ACGIH notice of intended changes. The proposed change is to lower the TLV for TDI to
0.001 ppm for an 8 hour TWA, with a 15 minute STEL of 0.003 ppm. The proposal for TDI also recommends adding a “Skin” notation and making the cancer designation “A3 – Confirmed Animal Carcinogen with Unknown Relevance to Humans”.
8.2 Exposure controls
Local exhaust recommended for thermal processing operations, as required to rethermal processing operations (including potentially some grinding operations) wear a NIOSH approved air-purifying respirator with organic
cartridge or supplied-air respirator if ventilation is inadequate. Replace cartridge according to respirator manufacturer’s changeout schedule.
