OSHA REGULATORY STATUS
As shipped this material is an inert aramid fiber reinforced honeycomb, which is coated with cured phenolic
resin. While this material is not classified as hazardous under OSHA regulations, this MSDS contains valuable
information critical to the safe handling and proper use of the product. This MSDS should be retained and
available for employees and other users of the product.

3. HAZARDS IDENTIFICATION
Flat sheets and blocks, brown in color, with slight characteristic odor. Decomposition and combustion products
may be toxic. Can decompose in a fire emitting toxic fumes and gases, carbon dioxide, carbon monoxide,
hydrogen cyanide, oxides of nitrogen and other toxic and irritation gases can be produced depending on
condition of combustion.


POTENTIAL HEALTH EFFECTS
Dusts may cause irritation or scratch the surface of the eye.
EYE:
Skin contact with dust and fibers of this product may produce itching and transient
SKIN:
mechanical irritation.
Ingestion is not expected to be a route of exposure. If ingestion occurs, treat
INGESTION:
symptomatically.
Inhalation of dust may result in itching and upper respiratory tract irritation.
INHALATION:

CHRONIC EFFECTS/ CARCINOGENICITY
This product is an aramid fiber reinforced honeycomb, which is coated with cured phenolic resin. While OSHA
does not regulate an aramid (aromatic polyamide) paper as a carcinogen, aramid fiber has been studied by the
scientific community for many years it presents a minimal risk to human health and the environment. When
mechanically working with these products, some dust may be generated. A percent concentration ratio of
Nomex paper is 19-77% (w/w). Generated dust can cause eye irritation, coughing and sneezing. Repeated
excessive exposures may cause chronic lung disorders. Repeated exposure to dust may cause chronic lung
disorders. None of the components present in aramid fiber at concentrations equal to or greater than 0.1% are
listed by IARC, NTP, OSHA or ACGIH as a carcinogen.




There are no hazardous components in this material as received, however, cutting, milling, drilling, routing or
otherwise fabricating this material may produce the following: particles - not other wise regulated, total dust. By
OSHA PEL TWA = 15mg/m3, ACGIH TLV is not listed.
Release of this material during processing as respirable and non-respirable dust should be controlled by
adequate local exhaust ventilation, good work practices, and use of personal protective equipment as needed.


MEDICAL CONDITION GENERALLY AGGRAVATED BY EXPOSURE

Persons with a history of chronic lung disease may be at increased risk from exposure to excessive levels of
nuisance dusts. Persons with medical conditions generally aggravated by mechanical irritants in the air or on
the skin may be at increased risk for a worsening of the underlying condition if exposed.

POTENTIAL ENVIRONMENTAL EFFECTS

This product as shipped is inert and should pose no significant hazard to the environment.




4. FIRST AID MEASURES
Flush with water for 15 minutes. Seek medical attention if irritation persists.
EYE:
Wash exposed area with soap and water. Do not rub or scratch irritated area. If fiberglass
SKIN:
becomes imbedded, seek medical attention.
Avoid ingestion. Treat symptomatically.
INGESTION:
Move individual to fresh air. Seek medical attention if irritation persists.

6. ACCIDENTAL RELEASE MEASURES
HEPA vacuum or wet wipe dusts and place in a disposal container. Avoid excess dust generation.


7. HANDLING AND STORAGE
Avoid contact with eyes. Avoid breathing dust. Minimize dust generation and accumulation. Store indoors in
dry area to protect material.


8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Provide local exhaust ventilation to maintain airborne levels below the
ENGINEERING
exposure limits. Minimize dust generation and accumulation.
CONTROLS:
Where dust is generated use a NIOSH approved half or full face air purifying
RESPIRATORY
respirator with dust/mist filter cartridges. Use in accordance with OSHA
PROTECTION:
regulations under 29 CFR 1910.134
Wear gloves impermeable to glass fibers. Wear loose fitting, long sleeved
SKIN PROTECTION:
clothing and long pants.
If dust is generated, wear chemical goggles or full-face respirator.
EYE PROTECTION:




GENERAL HYGIENE CONSIDERATIONS:
The health hazards associated with this material when used as recommended are mechanical skin, eye and
respiratory irritation associated with the generation of fiberglass composite dusts during machining or cutting.
The following general hygiene considerations are recognized as common, good industrial hygiene practices:

?? Wash hands after use and before eating
?? Shower at the end of the workday.
?? Wash work clothes separately and wipe out washer at the end of the cycle.
?? Avoid breathing dust
?? Wear safety goggles
