Section 3 - Hazards Identification
Emergency Overview
APPEARANCE AND ODOR: Yellow or gray fibrous glass blanket. Mild formaldehyde odor.
Inhalation of excessive amounts of dust from the product may cause temporary upper respiratory irritation and/or congestion--
remove individual to fresh air.
Products designed for high temperature applications (above 177潞C/350潞F) may release gases irritating to the eyes, nose and
throat during initial heat-up. In tightly confined or poorly ventilated areas, use air supplied respirators during the first heat-up
cycles.
Potential Health Effects
Summary
Breathing dust from this product may cause a scratchy throat, congestion, and slight coughing. Getting dust or fibers on the
skin, or in the eyes may cause itching, rash, or redness. Due to the thick diameters of continuous glass filament, the fibers
cannot be inhaled into the lower lung. Therefore, the effects of glass filament are limited to irritation of the upper respiratory
tract (nose, throat, upper airways).
When subjected to high heat and humidity, this product may release formaldehyde gas. Formaldehyde is irritating to the eyes
and respiratory system and is known to cause nasopharyngeal cancer (based on animal and human studies). Formaldehyde
may cause skin or respiratory sensitization (allergy).

Other irritating vapors, such as phenol and ammonia may also be released during curing or heat treatment. Phenol (vapor or
liquid) can be absorbed through the skin and may result in shock, collapse, coma, convulsions, cyanosis (skin turning blue),
and death. Long-term absorption may result in liver and kidney damage.
Hexamethylenetetramine (hexamine) exposure is not expected because it is physically fused to the product; however it is a
known skin irritant and sensitizer and its dust can irritate nose, mucous membranes and upper respiratory tract.
Inhalation
Irritation of the upper respiratory tract, coughing, and congestion may occur in extreme exposures. Severe irritation of the
mouth, nose, and throat, as well as signs of central nervous system depression (drowsiness, dizziness, headache), may occur
upon inhalation of vapors or gases.
Skin
Temporary irritation (itching) or redness may occur. Skin irritation and sensitization may result from contact with vapors, or
prolonged contact with uncured product.
Absorption
Although phenol can be absorbed through unprotected skin, the amount of free phenol in this product should not cause any
adverse effects. Absorption of phenol may result in paleness, weakness, sweating, headache, and ringing in the ears. Severe
exposures may result in shock, collapse, coma, convulsions, cyanosis (skin turning blue), and death. Formaldehyde is a skin
sensitizer.
Ingestion
Product is not intended to be ingested or eaten under normal conditions of use. If ingested, it may cause temporary irritation
to the gastrointestinal (GI) tract, especially the stomach.
Eyes
Temporary irritation (itching) or redness may occur. Exposure to vapors generated during the curing process may cause
irritation and burning in eyes.
Ears
Temporary irritation (itching) or redness may occur.
Primary Routes of Entry (Exposure)
Inhalation (breathing dust, fibers, or vapors), skin, and eye contact.
Target Organs
Throat, upper respiratory passages, lungs, skin, eyes, liver, and kidneys.
Medical Conditions Aggravated by Exposure
Pre-existing chronic eye, skin, respiratory, liver, or kidney diseases or conditions
Section 4 - First Aid Measures
First Aid: Inhalation
Remove to fresh air. Drink water to clear throat, and blow nose to remove dust.
First Aid: Skin
Wash gently with soap and water to remove dust. Wash hands before eating or using the restroom. If a rash develops, seek
medical attention.
First Aid: Ingestion
Product is not intended to be ingested or eaten. If this product is ingested, irritation of the gastrointestinal (GI) tract may occur,
and should be treated symptomatically. Rinse mouth with water to remove fibers, and drink plenty of water to help reduce the
irritation. No chronic effects are expected following ingestion.
First Aid: Eyes
Do not rub or scratch your eyes. Dust particles may cause the eye to be scratched. Flush eyes with large amounts of water for
5-15 minutes. If irritation persists, contact a medical professional.
First Aid: Ears
Wash exposed skin with soap and water. If irritation develops in the inner ear, seek medical attention.
First Aid: Notes to Physician
Irritating gases may be released under conditions of high heat or humidity. At high levels, these could cause severe upper
respiratory and eye irritation. Components of this product (formaldehyde, hexamethylenetetramine) are skin and respiratory
sensitizers. Treatment should be directed toward removing the source of irritation with symptomatic treatment as necessary.

PERSONAL PROTECTIVE EQUIPMENT
Personal Protective Equipment: Eyes/Face
Safety goggles are recommended to keep dust, fibers, gases, and vapors out of the eyes.
Personal Protective Equipment: Ears
Use ear protection (earplugs, hood, or earmuffs) to prevent airborne dust or fibers from entering the ear, if necessary.
Personal Protective Equipment: Skin
During prolonged contact with wet, uncured product, impervious gloves (butyl rubber and viton-fluorocarbon rubber) should be
worn to prevent excessive skin contact with phenol. Barrier creams may help reduce skin contact and irritation caused by fiber
glass, but may be ineffective against formaldehyde vapors that may be released during curing.
Personal Protective Equipment: Respiratory
A respirator should be used if ventilation is unavailable, or is inadequate for keeping dust and fiber levels below the applicable
exposure limits. In those cases, use a NIOSH-certified disposable or reusable particulate respirator with an efficiency rating of
N95 or higher (under 42 CFR 84) when working with this product. For exposures up to five times the established exposure
limits use a quarter-mask respirator, rated N95 or higher; and for exposures up to ten times the established exposure limits
use a half-mask respirator (e.g., MSA's DM-11, Racal's Delta N95, 3M's 8210), rated N95 or higher. Operations such as
sawing, blowing, tear out, and spraying may generate airborne fiber concentrations requiring a higher level of respiratory
protection. For exposures up to 50 times the established exposure limits use a full-face respirator, rated N99 or higher.
When heating uncured material, if vapor exposures exceed levels listed in Section 8B, use a full-face air-supplied respirator
(NIOSH-approved) to protect against irritating gases.
Ventilation
In fixed manufacturing settings, local exhaust ventilation should be provided at areas of cutting to remove airborne dust and
fibers. General dilution ventilation should be provided as necessary to keep airborne dust and fibers below the applicable
exposure limits and guidelines. The need for ventilation systems should be evaluated by a professional industrial hygienist,
while the design of specific ventilation systems should be conducted by a professional engineer.
Personal Protective Equipment: General
Wear a cap, a loose-fitting, long-sleeved shirt and long pants to protect skin from irritation. Exposed skin areas should be
washed with soap and warm water after handling or working with fiber glass. Clothing should be washed separately from other
clothes, and the washer should be rinsed thoroughly (run empty for a complete wash cycle). This will reduce the chances of
fiber glass being transferred to other clothing.

Chronic Toxicity
Continuous Filament Glass Fiber: No chronic health effects are known to be associated with exposure to continuous filament
fiber glass. Long-term epidemiologic studies do not show any increases in respiratory cancer or other disease among
employees who manufacture this product. In 1987, the International Agency for Research on Cancer (IARC) classified
continuous filament fiber glass as a Group 3 substance, "not classifiable as to its carcinogenicity to humans." In 2001, IARC
re-affirmed this designation. Because of the large diameter of continuous filament fibers, these fibers are not considered
respirable.

Exposure to formaldehyde gas (released under conditions of high heat or humidity) may cause eye and upper respiratory
irritation, and possible respiratory or skin sensitization (allergy). If sensitization occurs, subsequent exposures to formaldehyde
may worsen asthma or other respiratory problems, and cause allergic type reactions.
Exposure to formaldehyde gas has been associated with the development of nasal tumors in laboratory animals.
Formaldehyde has been classified as a probable human carcinogen, Group 2A, by the International Agency for Research on
Cancer (IARC). The US Occupational Safety and Health Administration (OSHA) and the US National Toxicology Program
(NTP) considered formaldehyde to have carcinogenic potential. OSHA specifically regulates formaldehyde under 29 CFR
1910.1048.
Phenol, present in the uncured product and in vapors generated during the curing process, may be absorbed through
unprotected skin. Absorption of phenol may result in paleness, weakness, sweating, headache, convulsions, cyanosis (skin
turning blue), and, in extreme cases, death.
Hexamethylenetetramine exposure is not expected to occur because this chemical is physically fused to the product. A 1955
study (Watanabe and Sugimoto) reported that hexamethylenetetramine produced tumors in rats when injected
subcutaneously. Hexamethylenetetramine is not listed by the International Agency for Research on Cancer as carcinogenic to
humans. Long-term studies in which rodents were fed hexamethylenetetramine in their drinking water showed no evidence of
carcinogenicity. Prolonged skin contact may produce a rash in humans similar to that of poison ivy.
