Long Term (Chronic) Health Hazards:   None currently known.

Section 4: First Aid Measure

Medical Conditions Aggravated by Exposure: None known

Eye Contact:   Flush eyes with water for at least 15 minutes – seek medical attention

Skin Contact: Rinse contact areas with room temperature to cool water, then wash gently with Mild soap.  If glass fiber becomes embedded, seek medical attention:

Inhalation: If irritation persists, seek medical attention.  IF SWALLOWED: Seek medical attention.

Section 5: Fire-fighting Measures

Flash Point, Flammable Limits, Extinguishing Media:

Water is the preferred extinguishing media.  Non-burning, Exposure to ignition source will burn-off surface binder leaving a bare glass residual similar to the initial product.

Unusual Fire and Explosion Hazards: Not applicable

Fire Fighting Procedures:

In any sustained fire, wear self-contained breathing apparatus (SCBA).  Every company should have written, MFPA & OSHA compliant, fire/evacuation policies including training for all facility employees.

Special Exposure Hazards from Fire:

Hazardous decomposition products of combustion from sizing and binders may be released in a sustained fire.  The larger part of the product is non-flammable E-glass. In a sustained fire, sizing and binders may decompose, releasing combustion products including carbon dioxide, carbon monoxide and water.  Additionally, there are many

chemicals that can evolve during any partial decomposition of chemical products.  The amounts or identities cannot be predicted and can differ in each situation.

Section 6: Accidental Release Measure

Steps to be taken upon Release of Spill:

Use vacuuming or wet sweeping methods instead of dry sweeping.

Waste Disposal Method:

Dispose in accordance with governmental regulations.  Keep debris minimal by locating waste disposal equipment near work areas.

Section 7: Handling and Storage


Keep airborne dust concentrations below regulated levels.  For optimum performance, store at 25 degree Celsius or less and relative humidity less than 65%.  Not an electrical conductor.  Can accumulate static charge.

Section 8: Exposure Controls Personal Protection

Respiratory Protection:

Some application of these products may not required respiratory protection for fiberglass.  However, if airborne fibrous glass concentrations exceed regulatory limits, respiratory protection approved for nuisance dusts is recommended.


Local exhaust ventilation (if needed) to minimize airborne dust levels.

Skin/Eye Protection:

Good personal hygiene and the use of barrier creams, caps, protective gloves, cotton coveralls, or long sleeved loose fitting clothing will maximize comfort.  Vacuum equipment may be used to remove fibers from clothes.  Work clothing should be laundered separately from other clothing.  Wear appropriate eye protection, which may

be safety glasses/side shields if there is a chance of airborne glass fibers contacting eyes.

Exposure Limits:

The American Conference of Governmental Hygienist  [ACGIH] has adopted a Threshold Limit Value [TLV] of 5mg/m3 for 8 hour time weighted average [TWA] exposure for fibrous glass dust, inhalable fraction.  The Occupational Safety and Health Administration [OSHA] does not prescribe Permissible Exposure Limit [PEL] for fibrous glass but relies on the PEL-TWAs for nuisance dust of 15 mg/m3 (total) and 5 mg/m3 (respirable).  Available air sampling/analytical methods: Gravimetric total dusts NIOSH Sampling & Analytical Method 0500; the Gravimetric respirable dusts NIOSH Method 0600 and the NIOSH 7400, B Fiber Counting Rules.  The later two methods may be performed as redundant verification that there are no respirable glass fibers.

Section 11: Toxicological Information

Factors in the fiber toxicity include: fiber dimensions and degree of exposure

Fiber Dimensions: Fibers are either non-respirable or respirable.  Respirable fibers can penetrate to thedeep” lung area.  According to the World Health Organization [WHO], man made-mineral fibers with diameters equal to or greater then 3.0 microns 9um) are nonrespirable.  According to the National Institute for Occupational Safety and Health [NIOSH], fibers with diameters equal to or greater than 3.5 micron (um) are nonrespirable.  The narrow, bending passages of the human respiratory system, do not permit the relatively larger, nonrespirable fibers to enter thedeep” lung area.  Instead, they stride the surfaces of the upper respiratory tract, nose or pharynx, and stop.  Nasal hairs or other natural mechanisms may then filter them.  Due to the manufacturing process used, the fiber glass products have diameters greater than 3.5 micron

and are considered to be nonrespirable.  The fibers do not become

respirable fibers upon the sanding/machine processing activities typical of our customers.  Upon breakage, the fibers may bread horizontally into smaller lengths but not longitudinally into smaller diameters.  As with any sanding/grinding activity, respirable dust may be generated.

Degree of Exposure:   According to Johnson ET. Al., in a 1969 US study of four fibrous glass production plants,  the results in terms of airborne concentrations of glass fibers and total dust would indicate that the workmens exposure to these materials is negligible”.

Carcinogenicity: The International Agency for Research of Cancer [IARC] is part of the World Health Organization [WHO].  LARC concludes that continuous fiberglass filaments are not classifiable as to their Carcinogenicity in human (Group 3) because there is inadequate evidence on the Carcinogenicity of these materials in humans or experimental animals. In a 1987 European study (over 20 years latency), there was no excess of respiratory cancer found.  In both studies, there was no increasing trend with an estimated time-weighted measure of exposure.  In a study

administering large diameter glass filament (> 3 um) intraperitionally to rats, no statistically significant tumor response was found.  The

American Conference of Governmental Hygienist [ACGIH] gives continuous filament fiber glass an A4 designation meaning there is adequate data to classify it as carcinogen.  Continuous filament fiberglass is not listed in the National Toxicology Program [NTP] 7th Annual Report on Carcinogens, nor is it regulated by OSHA as a carcinogen.

Section 12: Ecological Information

Fiberglass is generally considered to be an inert solid waste, and no special precautions should be taken in case it is released or spilled.  These products do not contain, nor are manufactured with; Class I or Class II Ozone-Depleting Chemicals [CFCs] identified in the Clean Air Act Amendment, 1990 List of Ozone Depleting Chemicals.

Section 13 and 14: Disposal and Transportation Consideration

Fiberglass is considered non-hazardous per EPA, RCRA, 40CFR, PART 361, 1990, considered an inert soled waste.  Local, state and national regulations should be consulted to ensure proper disposal procedures.  Fiberglass products, which are part of a reinforced plastic or uncured resin system, must be disposed of in accordance with applicable requirements for those plastics or resin when they exist.  Not regulated by the Department of Transportation [DOT].

Section 15: Additional Regulatory Information


Exempt from Canadian Environmental Protection Act [CEPA] reporting on the Domestic Substance Lists as these products are considered “articles.  Exempt from Workplace Hazardous Materials Information System [WHMIS] labeling & MSDS requirement.  However, fibrous glass is on the Ingredient Disclosure List.  It must be listed as an ingredient on MSDS for “controlled products” with fiberglass concentration greater than 1.0%.

European Economic Committee (EEC) Labeling Classification: Fiberglass does

not meet the classification for adangerous substance according to 67/548/EEC.  The E-glass composition has been incorporated in the EINECS under NR-65997-17-3 as a generic substance.

Japan: Chemical Substances Control Law: Fiberglass is exempt from this law.

United States: EPA Toxic Substances Control Act [TSCA]: Fiberglass carries no Chemical Abstracts Index name, CAS registry number or EPA code designation number.  Fiberglass is an “article as defined in Section 710.2[f].  It is exempt from Section 5 and 8[b] reporting requirements.  These products are exempted from EPA SARA Title III reporting as they do not meet its health or physical hazards definitions nor contain any SARA 313 chemical ingredients in excess of EPAs de minimous concentrations.

OSHA Hazard Communication Standard: Subject to the applicable requirements of this regulation.  Per this MSDS revision date, these fiber glass products are not known to contain chemical ingredients listed by the Pennsylvania, New Jersey or Massachusetts Right to Know Law or California’s Proposition 65 Law in excess of the amounts requiring reporting on such substance’s MSDS or labels.


NOTICE: Contact with fibrous glass may cause temporary skin irritation.  Wear long-sleeved, loose fitting clothing when handling the material.  Gloves and eye protection may be appropriate in certain operations.  Wash with soap and warm water after handling.  Use of a disposable mask in accordance with Occupational Safety and Health Administration 1910.134 respiratory protection requirements designed for nuisance dust is advisable where high dust levels may be encountered.  The International Agency for Research on Cancer [IARC] has designated continuous filament fiberglass as a group 3 not classifiable as to human carcinogenicity, meaning that evidence is not sufficient to link that fiber to cancer.
