4. FIRST AID MEASURES

Immediate or appropriate intervention or medical attention

Request medical intervention if there is a grounded suspicion that toxic combustion gases have been breathed, in case of carbonisation at low temperature and/or in the absence of air.

5. FIRE-FIGHTING MEASURES
The product is not inflammable, it is combustible (Fire class A – solid combustible substances)
Suitable extinguishing media	All types of extinguishing media are suitable. Cool containers exposed to fire by sprinkling with nebulised water.
Risks from exposure to the substance, the combustion products or gases produced	In case of fire toxic vapours of CO and NO_x are formed. Under certain combustion conditions, and particularly in carbonisation at low temperature, other toxic gases such as hydrocyanic acid may be formed.
Protective equipment for fire-fighting team	Self-contained breathing apparatus and fireproof overalls. In case of fire, the fire-fighting water should be let into the sewer system only after obtaining official authorisation, if possible. There should be no problem with the operation of biological treatment plants.
6. MEASURES IN CASE OF ACCIDENTAL RELEASE
Cleaning methods	Carefully sweep up the released product. Carefully clean traffic areas to prevent falls due to slipping. Examine the possibility to reuse or eliminate in conformity with existing regulations (also see sect. 13).
7. HANDLING AND STORAGE
7.1 Handling	Store preferably in compact form (bales or bags). Avoid storing outdoors if possible. In some operations involving an increase in product temperature, vapours may be generated by the finishing oils and/or residual solvent (DMAC), so a suitable exhaust system must be provided to ensure observance of TLV-ACGIHs in the workplace. Synthetic fibres, like natural fibres, may generate dust during the textile processing phase. The fibre is physiologically inert, but the concentration of breathable dust in the environment must be kept below the levels indicated in the TLV-ACGIHs. Keep away from flames and sparks. Beware of electrostatic charges.
Recommended equipment and procedures	Safety goggles, protective gloves and face-mask.
Prohibited equipment and procedures	The wearing of contact lenses should be avoided.
7.2 Storage
Specific design of areas and containers	Protect containers from physical damage and the action of heat (with roofs, sprinkler cooling systems, etc.).
Storage conditions	Store containers or bales in a cool, well-ventilated place. Keep away from flames and sparks. Do not smoke.
Special electrical system	Use adequate safety devices and provide electrical connections earthed against the accumulation of static electricity.
Packing used	Tow: bales of 400 kg – 500 kg – 1000 kg Staple: bales of 400 kg.
7.3 - Particular use	In case of particular use the manufacturer should be consulted beforehand.
8. EXPOSURE CONTROL/PERSONAL PROTECTION
Precautions and technical measures to adopt during use to minimise worker exposure	Regular cleaning of machinery, work areas and work clothing is recommended. Avoid inhaling dust.
Specific control parameters:
A) Environmental	ACGIH TLV-TWA: 10 mg/m³inert powders (Tab. 2006) TLV-TWA: 3 mg/m³ for the breathable fraction
B) Medical	D. Lgs n° 25/2000
Equipment that can provide adequate personal protection:	Gloves, goggles, face masks and safety shoes.
Specific hygiene measures	Wash hands carefully with soap and water before eating or smoking and after work.

10. STABILITY AND REACTIVITY
The product is stable under normal temperature and pressure conditions. It is chemically stable and resistant to dilute alkaline and acid solutions.
Conditions to avoid	Formation of inflammable mixtures with air (see sect. 9).
Hazardous decomposition products	Acrylic polymer decomposes at over 200°C. In case of combustion, depending on the temperature and quantity of air, the gases contain carbon monoxide, nitrogen oxides, carbon dioxide, water vapour, ammonia, nitrile, hydrocyanic acid and lower hydrocarbons.
11. TOXICOLOGICAL INFORMATION
Hazardous effects deriving from exposure to the substance		The products are not toxic. When properly used, the fibre products have never been known to have hazardous effects on the health. Quantities of less than 1% of finish normally applied to them have not been reported as irritating for the skin or mucous membranes. If special uses are contemplated for the products, such as in the food or healthcare industries, the manufacturer should be consulted beforehand.
	Indications on DMAC: DMAC is classified toxic for reproduction (category 2), harmful by inhalation and by contact with the skin. No labelling is requested for products which have DMAC content lower than 5%. The exposure limit is not changed. According to ACGIH (Table 2006) and EU Directive: TLV-TWA, OEL: 10 ppm = 36 mg/m3 Note: danger of cutaneous absorbtion.
Information on various exposure routes:
Inhalation	It may cause irritation. The fibres are normally retained in the upper respiratory tract. The literature indicates a value of LC50 on mice for inhalation of the gases developed by the combustion of 32 g/m³/10 min of acrylic fibre (3).
Ingestion	rat LD50 = > 2000 mg/kg performed with acrylic polymer (4).
Contact with skin and eyes	Not reported to be irritating to skin (5) or eyes (6) in tests performed with acrylic fibre.
Delayed and immediate effects to brief and prolonged exposure :
Sensitisation	No sensitisation caused by contact in guinea pigs (7).
Carcinogenesis	N.D.
Mutagenesis	No mutagenic activity was noted in the Ames test (8) (9)
Toxicity for reproduction (including teratogenesis)	N.D.
Narcosis	N.D.
12. ECOLOGICAL INFORMATION
Aquatic toxicity and other ecotoxicological data Behaviour in residual water treatment plants		The products are inocuous from the ecological standpoint. The residual solvent introduced into the waste water following hot/humid treatment of the products is readily biodegradable according to the MITI test (EU Directive 92/69) (10). During thermal treatment at temperatures between 130 and 190 °C, the finishing oil applied and the residual DMAC may volatilize. The waste water formed in the successive water processing must be sent to a water treatment plant in conformity with official provisions.
13. DISPOSAL CONSIDERATIONS
Suitable disposal methods	Pursuant to existing regulations, the product when it must be disposed of as waste falls into the category of special non-hazardous waste.
Incineration	Thermal destruction with energy recovery is possible in suitable incinerators.
EU regulations on waste	Directive 75/442 of 15 Jul 75 and amendments. Directive 91/689 of 12 Dec 91 and amendments Directive 94/67 of 16 Dec 94.
National provisions in force (in the absence of EU regulations)	According to specific national law.
14. TRANSPORT INFORMATION
Not classified as hazardous for purposes of national and international transport. (RID/ADR, FS Annex 7, M.M.M, IMO, IATA).
15. REGULATORY INFORMATION
EU labeling not required.
