4 FIRST AID MEASURES
Eye contact: Flush immediately with large amounts of water for at least 15 minutes after
removing any contact lenses. Eyelids should be held away from the eyeball to
ensure through rinsing. Do not rub eyes. Seek medical advice as good work
safety practice in all cases of eye contamination.
Skin contact: In case of skin irritation, remove contaminated clothing. Rinse affected areas
thoroughly with water and wash gently with soap and water. Do not rub or
scratch exposed skin. Using a skin cream or lotion after washing may be
helpful. If effects persist, seek medical advice.
Inhalation: Inhalation of the product is not anticipated. If it does take place, remove
exposed person/s from source of exposure to fresh air, drink water and blow
nose. Recovery should be rapid, but if effects persist seek medical advice.
Ingestion: Ingestion is unlikely, but if it does occur do not induce vomiting, rinse mouth
with water immediately. Product should be excreted naturally but if effects
persist, seek medical attention.
Advice to doctor: Acute effects are essentially temporary irritation in nature.

8 EXPOSURE CONTROLS AND PERSONAL PROTECTION
National Exposure Standards
No exposure standard has been established for this product by NOHSC, however National Exposure
Standards for the ingredients are shown below:
TWA STEL
Ingredient 3
mg/m3
fibres/ml mg/m fibres/ml
Synthetic mineral fibres* 0.5 2 - -
(inspirable dust)
Fumed silica - 2 - -
(respirable dust)
(Silicon dioxide, amorphous)
* There is no Exposure Standard specifically for AES fibres so the Exposure Standard of 0.5 fibres/ml for
all forms of synthetic mineral fibres has been applied. For situations where almost all the airborne
material is fibrous, a secondary, yet complementary, Exposure Standard of 2mg/m3 of inspirable dust is
applicable to minimise upper respiratory tract irritation. This dust standard is not to take precedence over
the respirable fibre standard.
Engineering Control Measures
Review the application in order to identify potential sources of dust exposure. This product is mastic.
Once dried out, it may generate dust.
Where possible, use exhaust ventilation and dust collection devices to reduce airborne fibre and dust
levels. Maintain workplace clean. Use vacuum cleaner fitted with a HEPA filter. Avoid brushing and
compressed air.
Where engineering control measures are not feasible or do not reduce airborne fibre/dust levels to below
0.5fibres/ml and/or 2mg/m3, or product has been exposed to greater than 900掳C, more extensive
precautions are required as outlined below in 鈥淧ersonal Protective Equipment鈥? .
Personal Protective Equipment
(i) For the installation of the product, the following is recommended:
Eye/Face protection: Where overhead work is involved, wear goggles or safety glasses with side
shields and head covering.
Skin protection: Wear long sleeve, loose fitting clothing and rubber gloves. Clothing should be
washed separately from other clothing to avoid cross-contamination.
Respiratory protection: For fibre/dust concentrations below the Exposure Standards (expected during
installation of product as per handling specified in this material safety data sheet),
respiratory protection is not required. A half-face respirator (Class P1, as
classified under AS/NZS1715 & 1716) may be used on a voluntary basis.

(ii) For the removal of the product in same condition as installed but in a dry state, the following is
recommended:
Eye/Face protection: Wear goggles or safety glasses with side shields and head covering.
Skin protection: Wear disposable coveralls or long sleeve, loose fitting clothing and rubber gloves.
Clothing should be washed separately from other clothing to avoid cross-
contamination.
Respiratory protection: Wear a half-face respirator (Class P1 or P2, as classified under AS/NZS1715 &
1716).
(iii) When the product has been exposed to temperatures greater than 900掳C for sustained periods, the
amorphous silicate (AES fibres and filler) begin to transform to mixtures of crystalline phases
including cristobalite, a form of crystalline silica. The occurrence and extent of crystalline phase
formation is dependant on the duration and temperature of exposure and the reaction occurs at the
鈥渉ot-face鈥? of the product. The presence of cristobalite can be confirmed only through laboratory
analysis.
The National Exposure Standard for cristobalite is 0.1mg/m3 TWA (Interim). The International
Agency for Research on Cancer (IARC) has classified crystalline silica inhaled in the form of quartz
or cristobalite, as Group 1 鈥淓stablished human carcinogen鈥?.
For the removal of the embrittled product likely to contain cristobalite or the removal is being
conducted in a poorly ventilated or enclosed space, the following is recommended:
Eye/Face protection: Wear goggles or safety glasses with side shields and head covering.
Skin protection: Wear disposable coveralls or long sleeve, loose fitting clothing and rubber gloves.
Clothing should be washed separately from other clothing to avoid cross-
contamination.
Respiratory protection: Wear a Class P2 half-face respirator (as classified under AS/NZS1715 & 1716).
In some circumstances where excessive levels of dust are created, the limitations
of filter loading capacity and facial seal may necessitate the use of:
鈥? A full-face (Class P3) cartridge respirator; or
鈥? A full-face (Class P3), powered air-purifying respirator; or
鈥? A full-face, positive pressure, demand airline respirator.

11 TOXICOLOGICAL INFORMATION
Irritant Properties
The definition of 鈥渋rritant鈥? contained in Appendix A of the Hazard Communication Standard 29 CFR
1900.1200 published by OSHA (Occupational Safety & Health Administration) of the U.S. Department
of Labour is 鈥溾? reversible inflammatory effect on living tissue by chemical action鈥︹?? AES fibres in this
product are an inert product, which do not interact chemically with exposed skin. When tested using
approved methods (European Commission Directive 67/548/EC, Annex V, Method B4- a European
Union publication), AES fibres give negative results for irritation. All man made mineral fibres, like
some natural fibres, can produce a mild irritation resulting in itching or rarely, in some sensitive
individuals, in slight reddening. Hence, there is a possibility that exposure to this product may cause
temporary mechanical irritation to the eyes, skin or respiratory tract (nose, throat, lungs). Unlike other
irritant reactions, this is not the result of allergy or chemical skin damage but as mentioned earlier, it is
caused by a temporary mechanical effect. This temporary irritation can be mitigated with proper handling
practices designed to minimise exposure and the use of personal protective equipment.
Other Animal Studies
The AES fibres in this product possess a fibre chemistry within the definition set by the European Union
under the classification of synthetic mineral fibres as a 鈥渕an-made vitreous fibre with random orientation
with alkaline oxide and alkaline earth oxide (Na2O + K2O + CaO + MgO + BaO) content greater than
18% by weight鈥?. These fibres have been designed to allow rapid clearance from lung tissue. This low
biopersistence has been confirmed in many studies on AES fibres using European Union protocol
ECB/TM/27 (rev 7) Nota Q, Directive 97/69/EC. The results for the short term biopersistence test by
inhalation was 6 days, well below the regulatory threshold of 10 days cited in the Directive 97/69/EC.
Based on these testing results, AES fibres based products are not regarded as potential carcinogens and
they are exempt from European (and therefore Australian) classification as such. When inhaled, even at
very high doses, they do not accumulate to any level capable of producing a serious adverse biological
effect. In lifetime chronic studies there was no exposure-related effect more than would be seen with any
鈥渋nert鈥? dust. Subchronic studies at the highest dose achievable produced, at worst, a transient mild
inflammatory response. Fibres with the same ability to persist in tissue do not produce tumours when
injected into the peritoneal cavity of rats.
Epidemiology
This product has not been the subject of epidemiological study. The IARC monograph on the evaluation
of carcinogenic risks to humans from man-made vitreous fibres reports that the Working Group elected

not to make an overall evaluation of the newer developed fibres designed to be less biopersistent such as
the alkaline earth silicate fibres. This decision was 鈥渕ade in part because no human data were available,
although such fibres that have been tested appear to have low carcinogenic potential in experimental
animals, 鈥︹??
