Eye Contact: Flush eyes with water for 15 minutes. Seek medical attention.
4.2. Most important symptoms and effects, both acute and delayed  
4.3. Indication of any immediate medical attention and special treatment needed  
SECTION 5: Firefighting measures  
5.1 Extinguishing Media: Water is the preferred extinguishing media; however, use the extinguishing agent suitable for the surrounding fire.
5.2. Special hazards arising from the substance or mixture  N/A Tecsil is completely non-flammable.
5.3 Advice for firefighters In any sustained fire, wear self-contained breathing apparatus (SCBA). Every company should have written, NFPA & OSHA compliant, fire / evacuations policies including training for all facility employees.
SECTION 6: Accidental release measure  
6.1. Personal precautions, protective equipment and emergency procedures  
6.2. Environmental precautions There may be specific local reporting requirements for the release of this material at the local, regional, or state level. However, there are no specific reporting requirements for this material as supplied under the Comprehensive Environmental Response Compensation and Liability Act (CERCLA) (40 CFR 302) or the Superfund Amendment and Reauthorization Act (SARA) (40 CFR 355).
6.3. Methods and material for containment and cleaning up  Use vacuuming or wet sweeping methods instead of dry sweeping.
6.4. Reference to other sections  
SECTION 7: Handling and storage  
7.1. Precautions for safe handling For optimum performance, store at 25°C (77°F) or less and relative humidity less than 65%. Keep in closed containers or original packaging to minimize airborne dust and contamination.
7.2. Conditions for safe storage, including any incompatibilities  
7.3. Specific end use(s)  
SECTION 8: Exposure controls/personal protection  
8.1. Control parameters  
8.2. Exposure controls  
Ventilation: Local exhaust ventilation to maintain appropriate airborne concentrations below the exposure guidelines specified by OSHA or other local, state and federal regulations.
Respiratory Protection:  Respiratory protection is not normally necessary. However, if airborne fiber concentrations exceed the TLV, respiratory irritation is experienced, or emergency situations warrant, respiratory protection approved for nuisance dusts is recommended which meets the requirements for OSHA's 29 CFR 1910.134.
Skin / Eye Protection:  Good personal hygiene and use of barrier creams, caps, protective gloves, cotton overalls, or long-sleeved loose fitting clothing will maximize comfort. Wear appropriate eye protection which may be safety glasses / side shields if there is a chance of airborne fibers contacting eyes.
SECTION 9: Physical and chemical properties  
9.1. Information on basic physical and chemical properties

9.2. Other information  
SECTION 10: Stability and reactivity  
10.1. Reactivity

10.3. Possibility of hazardous reactions N/A
10.4. Conditions to avoid  
10.5. Incompatible materials Incompatible with flourine, oxygen difluoride, chlorine bifluoride and alakalines. 
10.6. Hazardous decomposition products Thermal decomposition may be hazardous if respirable crystalline silica is formed after sustained exposures beyond 982°C (1800°F) or carbon monoxide and carbon dioxide are produced. The amount of crystalline silica present will depend upon the temperature and length of service.
SECTION 11: Toxicological information  
11.1. Information on toxicological effects  
Fiber Dimensions: Tecsil fibers are considered non-respirable due to their diameter greater than 3μ. The fibers do not become respirable upon breakage, where they normally break horizontally into smaller lengths but not longitudinally into smaller diameters.
Exposure: Persons with pre-existing skin and respiratory disorders may be more susceptible to the effects of contact with this material.


The International Agency for Research on Cancer (IARC) has concluded that continuous fiber glass filaments (including silica) are not classifiable as to their carcinogenicity in humans because of the lack of inadequate evidence in 20 year latency studies where no detectable tumor response or cancer evidence was found. The American Conference of Government Industrial Hygienists (ACGIH) gives fibrous glass dust an A5 designation, meaning it is not considered to be a carcinogen.
SECTION 12: Ecological information  
12.1. Toxicity Tecsil is generally considered to be an inert solid waste, and no special precautions are necessary when it is released or spilled.
12.2. Persistence and degradability
