Trade Names:
Microlite庐 AA Blankets OWR; Microlite庐 AA Blankets; Microlite庐 B Blankets
Microlite庐 AA Blankets WRP; Microlite庐 AA Premium NR;
Use:
Formed from resin bonded borosilicate 902 biosoluble glass fibers, Microlite庐 AA Blankets provide optimum thermal and
acoustical insulating performance for applications up to 450掳F. These blankets help control thermal and acoustical
transmission in a variety of aerospace applications, and are particularly well suited for insulating the fuselage wall cavities of
commercial and private aircraft.
Microlite庐 B Blanket is formed from flame attenuated borosilicate glass fibers and bonded with a thermosetting phenolic resin
binder. It is designed for applications in which good thermal and acoustical properties are required and where temperatures
are not in excess of 450掳F (232掳C). It is ideally suited for use in aircraft and other equipment applications where the higher
performance characteristics of Microlite庐 AA are not required.
Section 2 - Hazards Identification
Emergency Overview
Inhalation of excessive amounts of dust from the product may cause temporary upper respiratory irritation and/or congestion--
remove individual to fresh air.

Section 4 - First Aid Measures
First Aid: Inhalation
If dust is inhaled in excess of exposure limits referenced in section 8 of this safety data sheet, remove individual to fresh air.
Drink water to clear throat, and blow nose to remove dust. A saline spray in the nose may help clear any fibers.
First Aid: Skin
Wash gently with soap and water to remove dust and fibers. Alternatively, fibers can be removed from the skin by use of
ordinary masking or wrapping tape. Should irritation persist, seek medical attention.
First Aid: Ingestion
Rinse mouth with water to remove dust and fibers and drink plenty of water to help reduce irritation. If irritation persists, seek
medical attention.
First Aid: Eyes
Do not rub or scratch eyes. Dust particles may cause the eye to be scratched. Flush eyes with large amounts of water until
irritation subsides. If irritation persists, seek medical attention.
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
Dust from the product may cause mechanical irritation of the eyes, skin, and upper respiratory tract. Treat symptomatically.
Irritating gases may be released under conditions of high heat or humidity. At high levels, these could cause severe upper
respiratory and eye irritation. Formaldehyde gas is a skin and respiratory sensitizer. Treatment should be directed toward
removing the source of irritation with symptomatic treatment as necessary.

Section 6 - Accidental Release Measures
Clean-Up Procedures
Pick up large pieces. Vacuum dusts. If sweeping is necessary, use a dust suppressant such as water. Do not dry sweep dust
accumulation. These procedures will help to minimize potential exposures.
Section 7 - Handling and Storage
Handling Procedures
Use protective equipment as described in Section 8 of this safety data sheet when handling uncontained material. Handle in
accordance with good industrial hygiene and safety practices.
Storage Procedures
Warehouse storage should be in accordance with package directions, if any. Material should be kept clean, dry, and in original
packaging.
Section 8 - Exposure Controls / Personal Protection
The Occupational Safety and Health Administration (OSHA) has not adopted specific occupational exposure standards for
fiber glass. Fiber glass is treated as a nuisance dust and is regulated by OSHA as a particulate not otherwise regulated (total
dust) shown in CFR 1910.1000 Table Z-3.
Respirable fraction 5 mg/m3
Total dust 15 mg/m3
JM has adopted the fiber glass industry voluntary Product Stewardship Program (PSP), formerly the NAIMA-OSHA Health and
Safety Partnership Program (HSPP). Under the PSP, JM recommends that exposures be limited to the voluntary concentration
of 1 f/cc TWA for fibers longer than 5 microns with a diameter less than 3 microns. This will help minimize potential irritation
effects. The PSP also includes the PPE recommendations described below.
Component Exposure Limits
Formaldehyde (50-00-0)
OSHA: 0.75 ppm TWA
0.5 ppm Action Level; 0.75 ppm TWA; 2 ppm STEL (Irritant and potential cancer hazard - see 29
CFR 1910.1048)
3 ppm TWA (unless specified in 1910.1048)
ACGIH: 0.3 ppm Ceiling
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: Ears
Use ear protection (earplugs, hood, or earmuffs) to prevent airborne dust or fibers from entering the ear, if necessary.
Personal Protective Equipment: Skin
Leather or cotton gloves should be worn to protect against mechanical abrasion. See also Personal Protective Equipment:
General, below.
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 referenced in Section 8 of this SDS. Wear a NIOSH-certified disposable or reusable particulate respirator with
an efficiency rating of N95 or higher (per 42 CFR 84) when dust or fiber concentrations exceed the applicable exposure limits.
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.
Ventilation
In fixed manufacturing settings, local exhaust ventilation should be provided at areas of cutting, milling or other processing to
remove airborne dust and fibers.
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 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.

Section 11 - Toxicological Information
Acute Toxicity
A: General Product Information
Dust from this product is a mechanical irritant, which means that it may cause temporary irritation or scratchiness of the throat,
and/or itching of the eyes and skin.
Exposure to formaldehyde 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.

Formaldehyde (50-00-0)
Inhalation LC50 Rat: 0.578 mg/L/4H; Oral LD50 Rat:500 mg/kg
Carcinogenicity
A: General Product Information
Exposure to formaldehyde has been associated with the development of nasopharyngeal cancer in laboratory animals and
humans. Formaldehyde has been classified as a known human carcinogen, Group 1, by the International Agency for Research
on Cancer (IARC). The US Occupational Safety and Health Administration (OSHA) and the US National Toxicology Program
(NTP) consider formaldehyde to have carcinogenic potential. OSHA specifically regulates formaldehyde under 29 CFR
1910.1048.
B: Component Carcinogenicity
Fiber Glass Wool
ACGIH: A3 - Confirmed animal carcinogen with unknown relevance to humans
NTP: Reasonably Anticipated To Be A Human Carcinogen (respirable size)
IARC: Group 3 - Not Classifiable (IARC Monograph 81 [2002] (listed under Man-made mineral fibres),
Monograph 43 [1988])
Formaldehyde (50-00-0)
ACGIH: A2 - Suspected Human Carcinogen
OSHA: 0.5 ppm Action Level; 0.75 ppm TWA; 2 ppm STEL (Irritant and potential cancer hazard - see 29
CFR 1910.1048)
NTP: Reasonably Anticipated To Be A Human Carcinogen (Possible Select Carcinogen)
IARC: Group 1 - Known Human Carcinogen
Chronic Toxicity
The U.S. Department of Health and Human Services, National Toxicology Program (NTP 1998, 2000, 2002) classified glass
wool (respirable size) as reasonably anticipated to be a human carcinogen, based on sufficient evidence of carcinogenicity in
animals. This assessment was originally prepared in 1993-1994 for the 7th Report on Carcinogens (NTP 1994), but has not
been updated since then in the 8th, 9th, or 10th Reports on Carcinogens (NTP 1998, 2000, 2002).
