MATERIAL SAFETY DATA SHEET
Target organs:
Lungs, Eyes, Skin.
Primary route(s) of entry:
Inhalation.
Acute effects:
Upper respiratory irritation, including irritation of throat. Irritation and inflammation to eyes
on contact and to the skin on prolonged contact.
Chronic effects:
The international agency for research on Cancer (IARC) reviewed the carcinogenicity data
on man-made vitreous fibers (including RCF) in 1987. IARC classified RCF as 鈥減ossibly
carcinogenic to humans鈥? Group 2B. IARC鈥檚 classification of RCF was based on sufficient
evidence of carcinogenicity in experimental animals in the absence of data on the
carcinogenicity of RCF to humans. Additionally, IARC classified cristobalite, which may be
found in after-service RCF, and quartz, which may be found at low levels in some of the
raw materials as 鈥淜nown Human Carcinogens 鈥? Group 1. NTP lists the respirable
polymorphs of crystalline silica (cristobalite and quartz) amongst substances which may
鈥渞easonably be anticipated to be carcinogens鈥?. The long-term, excessive inhalation of
respirable RCF and/or dust particulate containing crystalline silica in the respirable size
range, may contribute to the development of industrial bronchitis reduced breathing
capacity, and lead to increased susceptibility to other lung disease.
Signs & symptoms of overexposure:
Eye contact:
Fiber and/or particulate may contribute to the development of moderate eye
irritation.
Skin Contact:
Abrasiveness of fiber may contribute to the development of skin irritation.
Inhalation:
Inhalation of airborne particulate can irritate upper respiratory system as well as the
throat.
Ingestion:
An unlikely route of exposure. If ingested in sufficient quantity, may cause
gastrointestinal disturbances. Symptoms will include irritation and may include
nausea, vomiting and abdominal pain.
IV FIRST AID MEASURES
Eye contact:
Flush eyes, including under the eyelids, with large amounts of water. If irritation persists,
seek medical attention.
Skin contact:
Wash affected areas with mild soap and water.

MATERIAL SAFETY DATA SHEET
Inhalation:
Remove victims from adverse environment to fresh air.
Ingestion:
Ingestion is an unlikely route of exposure. If ingested in sufficient quantity and victim is
conscious, give 1-2 glasses of water or milk. Never give anything by mouth to an
unconscious person. Leave decision to induce vomiting to qualified medical personnel,
since particles may be aspired into the lungs. Seek immediate medical attention.
V FIRE FIGHTING MEASURES
NFPA Code: Flammability: 0 Health: 0 Reactivity : 0 Special : 0
Fire and Explosion:
Product is not considered flammable nor combustible, but some flame may be observed
(from starch component) if the product is involved in a fire. Product will emit smoke and
fume upon initial exposure to high temperature.
Products of combustion:
Products of combustion may include CO, CO2, SOx . The exact composition of the gases
will depend on conditions of combustion.
Extinguishing Media:
Use extinguishing media appropriate to combustibles in area of fire.
Fire fighting instructions:
Firefighters should wear NIOSH-approved, positive pressure, self-contained breathing
apparatus and full protective clothing when appropriate.
VI ACCIDENTAL RELEASE MEASURES
Spill procedures:
Carefully, cleanup and place material into a suitable covered container, being careful to
avoid creating any airborne dust; Use EPA filtered vacuum equipment if available, if not,
use a dust suppressant with sweeping; do not use compressed air. Clean-up personnel
should wear approved respiratory protection, gloves, and goggles to prevent irritation from
contact and/or inhalation.
VII HANDLING AND STORAGE
These products are stable under all conditions of storage. Store in original container in a dry area.
Keep container closed when not in use. Avoid creating dust.
VIII EXPOSURE CONTROLS AND PERSONAL PROTECTION
Engineering controls:
Pending results of long-term health effects studies, engineering controls (i.e. ventilation)
and work practices to control levels of airborne fibers to the lowest level attainable. Provide
sufficient ventilation, in both volume and airflow patterns, to control the fiber/dust
concentrations below allowable exposure limits.
Page 3 of 8
MATERIAL SAFETY DATA SHEET
Personal protective equipment:
Goggles, gloves, respirators, long sleeve clothing and head covering.
Respiration protection:
Nutec Fibratec currently recommends an exposure limit of 0.5 fibers per cubic centimeter
(0.5 f/cc) for respirable airborne ceramic fiber as an 8-hour time weighted average
exposure. Provide workers with NIOSH/MSHA-approved respirators in accordance with
requirements of 29 CFR 1910.134 when airborne concentrations of respirable fiber and/or
cristobalite exceed the recommended limits.
The following are recommended respirator types for varying respirable airborne concentrations of
ceramic fiber and/or cristobalite.

3M 7800 with 7255 filters) or powered air-purifying respirator
(PAPR) with HEPA filtered cartridge.
> 2.5 mg/m3
> 25 f/cc Any supplied-air respirator operated in positive pressure mode
(example: 3M 7800 with W9435 hose and W3196 regulator
connected to clean air supply).
Airborne fiber and cristobalite concentrations are determined by time-weighted air samples
collected and analyzed using NIOSH method 7400 (鈥淏鈥? counting rules) and 7500, respectively.
Exposures are expressed as 8-hour time weighted averages.

XI TOXICOLOGICAL INFORMATION
Epidemiology:
Industry epidemiologic investigations of RCF production workers and surveillance of
1
customer鈥檚 employees using RCF is ongoing. Preliminary interim results , obtained from
employees in RCF manufacturing facilities, is as follows:
1. - There is no evidence of any fibrotic lung disease (interstitial fibrosis) on x-ray.
2. - There is no evidence of any lung disease among those employees exposed to RCF
that have never smoked.
3. - A statistical trend was observed in exposed population between the duration of
exposure to RCF and a decrease in some measures of pulmonary function. These
observations are clinically insignificant. In other words, if these observations were made on
an individual employee, the results would be interrupted as being with in the normal range.
4. 鈥? Pleural plaques (thickening along the chest wall) have been observed in a small
number of employees who had a long duration of employment. There are several
occupational and non-occupational causes for pleural plaque. It should be noted that
plaques are not pre-cancer nor are they associated with any measurable effects on lung
function.
Toxicology:
The International Agency for Research on Cancer (IARC) reviewed the carcinogenicity data
on man-made vitreous fibers (including ceramic fiber, glasswool, rockwool, and slagwool)
and classified MMVF as a possible human carcinogen (Group 2B). IARC鈥檚 2B classification
was based on sufficient evidence of carcinogenicity in the experimental animals and
inadequate evidence (no data) of the carcinogenicity in the experimental of ceramic fiber
to the humans.
A number of studies on the health effects of inhalation exposure of rats and hamster have
recently been completed. In a lifetime nose-only inhalation study2,3, rats exposed the
Maximum Tolerated Dose of 30 mg/m3 (approximately 200 fibers /cc) developed
progressive lung damage and cancers of the lung and of the pleura (lining of the chest wall
and lung). In contrast, hamsters similarly exposed developed interstitial fibrosis and pleural
cancer, but no lung cancer. Cancer of the pleura is called mesothelioma.

In another lifetime nose-only inhalation study 4,5, rats were exposed to three different
concentrations of RCF (3,9, and 16 mg/m3 , approximately 25 , 75 and 115 fibers per cc
respectively). The data from this study demonstrated a dose-response relationship in the
biological affects of RCF in rats. There is no RCF related increase in lung tumors at 3, 9, or
16 mg/m3 . A pleural fibrosis and mesothelioma were seen in single rat in the mid-dose (9
mg/m3) group. In addition, no consistently diagnosed fibrosis was seen below 9 mg/m3.
Pulmonary fibrosis was observed at 9 and 16 mg/m3.
