2.2 Remarks concerning special constituents
2.2.1 Preparation
The fibre product is not toxic. It may contain up to 0.9% of a fibre finish. In cases
where the product is to be used for special applications such as in the foodstuffs
industry, the hygienic, medical or surgical sectors, please approach the
manufacturer first. When the fibre product is used as intended, no detrimental
effects on health are known to date.
Fibres and yarns are generally treated with a finishing agent to facilitate
processing. These finishes, spooling oils and sizing agents can generally be
removed in an aqueous medium if necessary.

When subjected to heat treatment at temperatures between approximately
130掳C and 190掳C, the finish coating can evaporate or decompose. If subsequent
processing involves water, resultant waste water must be directed into a
purification plant to comply with local regulations.
2.2.2 Residual solvents
Production of DOLANIT means that the fibre still contains small residual
quantities of the solvent dimethyl formamide (DMF), which can be released
when tows and fibres are subjected to further processing, especially in
conjunction with high temperatures.
In accordance with the EC guidelines, implemented in German Law in the
Hazardous Material Regulations (GefStoffV) of October 1993 (last altered in
06/1998), DMF is classified and characterised as follows:
Classification: hazard symbol T, hazard characterisation "toxic"
Characterisation:
R codes:
R61: may be toxic to foetuses
R20/21: also hazardous to health when breathed in or on contact
with the skin
R36: irritates the eyes
S-codes:
S53: avoid exposure - obtain special instructions before use
S45: seek medical attention immediately in the case of an accident
or if the subject feels ill (if possible, show this label)
In the July 1997 edition of the List of Maximum Workplace Concentrations (MAK
values list) issued by the Senate Commission for the Examination of Harmful
Materials of the German Research Co-operative, the following information on
DMF is cited:
MAK: 10 ppm; 30 mg/m鲁; peak limit: exceeding factor 4; comment: 掳H (skin
resorptive); pregnancy group B.
The following information on DMF is listed in the TRGS 905 "Index of
Carcinogenic, Gene-Altering and Reproductively Hazardous Materials"
(Verzeichnis krebserzeugener, erbgutver盲ndernder und
fortpflanzungsgef盲hrdender Stoffe), issued in June 1997 (last altered in
05/1998):
Category 2 reproductive hazard RE (developmentally damaging).
In Appendix E of the Technical Instructions for the Preservation of Air Purity (TA-
Luft) of February 1986, DMF is assigned to Class II. This means that for a mass
flow of 鈮? 2 kg/h, emissions may not exceed a mass concentration of 0.1 g/m鲁.

IARC Evaluation, version dated February 1998, in monograph no. 47:
The IARC (International Agency for Research on Cancer) has classified DMF in
Group 3. This means that, with respect to a carcinogenic effect on humans, DMF
is non-classifiable.
The results of our own tests on the concentrations of DMF in people's respiratory
air (8 hours' mean value) when processing DOLAN with appropriate ventilation
showed the following concentrations:
ring spinning < 0.1 ppm
It is known that similar concentrations have been found in conjunction with rival
products at processing companies in the USA. The concentrations measured
when our fibres are being processed are thus well below the MAK value of 10
ppm. Animal experimentation significant to changes in MAK grading only
showed damage to embryos at values above 50 ppm.
3. Possible hazards
Overview of hazards
The fibre product DOLANIT is not reactive under normal environmental conditions. It
has been manufactured and processed now for over 10 years without knowledge of
health hazards when the product is used as intended. Fibre dust can occur during
normal processing. At higher processing temperatures, finish and solvent residues can
be released at the workplace (cf. item 2.2.1).
4. First aid measures
4.1 Inhalation
If the applicable MAK values are adhered to, a health hazard from breathing this
product in is unlikely. Therefore no special treatment is necessary.
Fibre fly, dust and decomposition products are to be avoided by aspiration and
ventilation. If someone is exposed to excessive levels of fibre dust or fibre fly, he should
go into the fresh air and seek medical advice if coughing or other symptoms develop.
4.2 Eyes
The eyes should be rinsed immediately with plenty of water. If irritation persists, medical
advice should be sought.
4.3 Skin
Wash with soap and water. Medical advice should be sought if irritation develops.

4.4 Swallowing
No special measures required.
5. Fire-fighting measures
5.1 Combustion properties
Flash point: not applicable.
Product will burn in fire.
Extraneous ignition temperature: (1a) 250掳C with finish
Auto-ignition temperature: (1a) approx. 515掳C
Decomposition temperature: (1b) from 240掳C
Fire and explosion protection
Avoid or eliminate fibre fly. A build-up of fibre dust or fibre fly could represent a fire
hazard in sufficient concentrations.
Keep away from ignition sources. Observe effects of electrostatic charge.
Dangerous products of combustion:
In case of fire, dangerous flue gases are as follows: carbon monoxide, carbon dioxide,
nitrogen oxides.
Under certain conditions, tiny amounts of other toxic gases such as hydrogen cyanide
cannot be ruled out, especially in conjunction with smouldering fires.
If there is a danger that toxic combustion gases may have been breathed in during a
smouldering fire, immediate medical treatment is essential.
5.2 Extinguishing agents:
Suitable: all usual extinguishing agents.
Unsuitable: water, if the fire was caused by electrical short circuit.
5.3 In the case of fire-fighting in enclosed spaces, respiratory equipment must be used
which is independent of the ambient air.
6. Measures to be taken in case of unintentional release
Before cleansing, the following sections should be consulted: "Fire-fighting measures"
and "Handling and storage." During the cleansing procedure, use appropriate "personal
protective equipment."

7. Handling and storage
All bales must be stored in accordance with the appropriate regulations.
8. Limitation of exposition and personal protection
8.1 Avoid fibre fly, fibre dust and decomposition products from the preparation by aspiration
and ventilation.
8.2 Personal protective equipment
8.2.1 Eye protection
Protective glasses with side shields must be worn, e.g. when cutting the
package covering and straps.
8.2.2 Skin protection
Fibres which are processed at high speeds can cause injuries such as grazes
and cuts. It is good industrial practice to minimise skin contact.
8.2.3 Respiratory equipment
Normally not necessary. Necessary in cases of fire (see 5.1).
8.3 Exposition limits
General dust limit value MAK 6 mg/m3.

10. Stability and Reaction
10.1 Chemical stability: stable
10.2 Conditions to be avoided

Incompatible with aqueous lyes and amines due to yellowing.
10.4 Degradability
See 10.3: decomposition products include ammonia, nitrile, polyacrylamide, polyacrylic
acid.
Also occurs in conjunction with a thermal load above 240掳C.
10.5 Polymerisation
Polymerisation will not occur.
11. Information regarding toxicology
The preparations added to the staple fibre or short staple are not irritant according to
tests for skin and mucous membrane compatibility in accordance with the OECD
standard, tested on rabbits or rabbits' eyes.
12. Details on ecology
12.1 Eco-toxicological information
The finishes can be eliminated to over 90% in accordance with OECD 302 B (Zahn-
Wellens Test, 7 days).
12.2 Details concerning eco-chemical properties
Our own tests to investigate DOLANIT's resistance to rotting after storage in climatized
cultivated soil have shown that the product is very stable after 21 months' storage, as
shown by the determination of the tearing strength. These findings are also confirmed in
publications by other authors.
13. Notes on disposal
Waste disposal
Dispose of the fibre product as non-hazardous waste in a licensed disposal plant in
accordance with local authorities' regulations.
The material can also be burned in a licensed incineration plant.
