Health Effects
Enter text or highlight term...
Acute Health Effects: From MSDS
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.

Target Organs: Nose (nasal passages), throat, lungs, skin, eyes.
Primary Routes of Entry (Exposure): Inhalation (breathing dust), skin, and eye contact.

Potential Health Effects
Inhalation: Irritation of the upper respiratory tract (scratchy throat), coughing, and congestion may occur in extreme exposures.
Skin: Temporary irritation (itching) or redness may occur.
Absorption: Not applicable
Ingestion: This product is not intended to be ingested (eaten). If ingested, it may cause temporary irritation to the gastrointestinal (digestive) tract.
Eyes: Temporary irritation (itching) or redness may occur.
Ears: Temporary irritation (itching) or redness may occur.

Medical Conditions Aggravated by Exposure
Pre-existing chronic respiratory, skin, or eye diseases or conditions.
Chronic Health Effects: From MSDS
Refer to section on Carcinogenicity.
Carcinogenicity: From MSDS
Component Carcinogenicity
Continuous filament glass fibers (See Generic CAS # 65997-17-3)
ACGIH: A4 - Not Classifiable as a Human Carcinogen
IARC: Group 3 - Not Classifiable (IARC Monograph 43, 1988; Monograph 81, 2002)
Glass Wool Fiber (65997-17-3)
ACGIH: A3 - Confirmed animal carcinogen with unknown relevance to humans
NTP: Reasonably Anticipated To Be A Carcinogen (respirable size)
IARC: Group 3 - Not Classifiable (IARC Monograph 43, 1988; Monograph 81, 2002)
Wood dust (Not Available)
NTP: Known Carcinogen
IARC: Group 1 - Known Human Carcinogen (IARC Monograph 62, 1995)
Chronic Toxicity
Polyisocyanurate Foam: There is no evidence that dust from this material causes disease in man. There are no known animal studies of the chronic health effects of breathing dust from polyisocyanurate foam. However, a subchronic inhalation study showed no adverse respiratory effects in rats as a result of breathing 9 mg/m3 of dust from a similar foam (polyurethane foam) for 3 months (Thyssen et al., 1978). In 1987, IARC designated polyurethane as Group 3, not classifiable as to carcinogenicity
to humans (Monograph 19).
Wood Dust: Risk of a rare form of nasal cancer has been associated with wood dust exposure. In the 1960's studies relating wood dust exposure in the furniture industry with nasal cancer were first reported in England. The link was confirmed in several other European countries and furniture industries. Studies of the furniture industry in the United States have shown notably lower-to-no increased risk of nasal cancer. Studies examining chronic exposure to wood dust have also been conducted outside of the furniture industry. Results from these studies have been inconsistent with the findings from studies of the furniture industry. Studies showing a link to nasal cancer have been primarily conducted in industries using hardwood. In 1980 the International Agency for Research on Cancer (IARC) reviewed the studies and concluded that there is a known risk of cancer in the furniture industry and a possible risk of cancer for carpenters and joiners.
Wood products can be contaminated with a saprophytic fungi (alternaria species) that when inhaled can cause hypersensitivity pneumonitis, an allergic condition that can lead to chronic disease and irreversible pulmonary damage. This fungi has been detected in wood pulp, and is believed to have caused lung disease in lumber mill workers. Also, reduced pulmonary function has been reported by some observers in workers who have been exposed to excessive levels of wood dust for prolonged periods of time, however these results have not been found consistently across all studies.
Fiber Glass Wool: In October 2001, IARC classified fiber glass wool as Group 3, not classifiable as to its carcinogenicity to humans. The 2001 decision was based on current human and animal research that shows no association between inhalation exposure to dust from fiber glass wool and the development of respiratory disease. This is a reversal of the IARC finding in 1987 of a Group 2B designation (possibly carcinogenic to humans) based on earlier studies in which animals were injected with large quantities of fiber glass. NTP and ACGIH have not yet reviewed the IARC reclassification or the most current fiber glass health research; at this time

Handling/Disposal
Handling: From MSDS
Use protective equipment (see below) when handling uncontained material.
Storage Procedures
Warehouse storage should be in accordance with package directions, if any. Material should be kept dry, and protected from the elements.

Personal Protective Equipment:
Personal Protective Equipment: Eyes/Face
Safety glasses with side shields are recommended to keep dust out of the eyes.
Personal Protective Equipment: Skin
Leather or cotton gloves should be worn to prevent skin contact and irritation. Barrier creams may also be used to reduce skin contact and irritation caused by fiber glass.
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.

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.
Disposal: From MSDS
This product, as supplied, is not regulated as a hazardous waste by the U.S. Environmental Protection Agency (EPA) under Resource Conservation and Recovery Act (RCRA) regulations. Comply with state and local regulations for disposal. If you a
