Guidance on Safe Use

First-aid measures

First-aid measures

General advice: Remove victims out of the danger area without endangering your own safety. Remove contaminated clothing and shoes immediately.

In case of skin contact: The contaminated parts of the body must be wiped off and preferably washed with plenty of water and soap. In case the body or limbs have been contaminated, shower the whole body and pay proper attention to the cleaning of the hair and nails. In case of skin irritation, consult a physician.

In case of eye contact: In case of contact with eyes flush immediately with plenty of flowing water for 10 to 15 minutes holding eyelids apart and

consult an ophthalmologist.

If inhaled: In case of inhalation of products, affected person should be moved into fresh air, loosed any tight garments and kept still and warm. In case breathing has stopped or interrupted, use artificial (mouth-to-mouth) respiration. If respiration is hampered, use oxygen respiration. Prevent the inbreathing of any vomit. Seek medical advice.

If swallowed: Obtain immediate medical attention. DO NOT induce vomiting. If accidentally swallowed rinse the mouth with plenty of water (only if the person is conscious).

Notes to physician: The product irritates the respiratory tract and may trigger sensitisation of the skin and respiratory tract. Treatment of acute

irritation or bronchial constriction is primarily symptomatic. Following severe exposure the patient should be kept under medical review for at least 48 hours.  

Fire-fighting measures

Fire-fighting measures

Suitable extinguishing media: Foam, CO2 or dry extinguishing powder. Water spray may be used if no other is available and then in copious quantities. Prevent washings from entering water courses, keep fire exposed containers cool by spraying with water.

Unsuitable extinguishing media: High volume water jet.

Special hazards, combustion products: Combustion products may include: carbon oxides (CO, CO2), nitrogen oxides (NO, NO2 etc.), hydrocarbons and ammonia. When in contact with oxidizing substances may result in sudden reactions, possibly fire.

Special protective equipment: Wear self-contained breathing apparatus and full protective suit.

Accidental release measures

Accidental release measures

Personal precautions: Immediately contact the emergency personnel. Evacuate the affected area. Areas of leakage must be closed down if this can be done without personal injury. Avoid the inhalation of dust. Clean-up should only be performed by trained personnel.

People dealing with major spillages should wear full protective clothing including respiratory protection. Use suitable protective equipment (section Exposure Controls/Personal Protection). Keep away from sources of ignition. Provide adequate ventilation. Keep unauthorized persons away.

Environmental precautions: Avoid dispersal of spilt material and runoff and contact with soil, waterways, drains and sewers. The material must be stopped from entering the drainage system, manholes and sewage system. Protect spread of the material by encircling it with suitable absorbent material (sand, soil, perlite). A hazard is posed for drinking water sources when larger quantities enter the groundwater. Inform the relevant authorities.

Methods for cleaning up: Wash the contaminated surfaces with plenty of hot water and collect the washing water after suitable pre-treatment discharge to waste water sewage. Other adsorbent materials should be collected and considered as hazardous wastes.

Other information: Remove any ignition sources. Basic and/or acidic dilutions can not be used for clean-up.  

Handling and storage

Handling and storage

Handling: Handle the material with care. Ensure proper ventilation including floor level. Refill and handle product only in closed systems; vented air should pass scrubbers / filters prior to being released to the environment. The efficiency of the ventilation system must be regularly monitored due to the possibility of blockage. When using do not eat, drink, smoke. Avoid contact with skin and eyes and inhalation of vapours. Eye bath and emergency shower are required. Handling is allowed only by trained employees in properties of the material and trained in proper use of personal protective equipment with an emphasis on the disposal of contaminated gloves and clothing. The personal protective measures described below must be observed. Due to the risk of self-ignition originating from quick oxidation, avoid the use of glass-wool insulations. Prevent electrostatic charge, sources of ignition should be kept sufficiently clear and fire extinguishers should be kept at hand. Take organizational measures to limit any potential exposure.. The floor must be solvent resistant.

Do not leave container open. Use leak-proof equipment with exhaust for refilling or transfer.

Fill only into a labelled container. Use solvent resistant utensils.

Storage: Store in accordance with local regulations. Store in the original container protected from direct sunlight in a dry, cool and well-ventilated area, away from incompatible materials, food and drink. Keep container tightly closed and sealed until ready for use. Containers that have been opened must be carefully resealed and kept upright to prevent leakage. Do not store in unlabelled containers. Use appropriate containment to avoid environmental contamination.

Suitable containers: steel, stainless steel.

Unsuitable containers: copper, copper alloy and galvanised surfaces.

Other information: Use explosion-proof electric appliances.

Personal protection:

a. Respiratory protection: Required if vapours are formed; gas-filter for vapours of organic compounds (boiling point > 65 °C, e. g. EN 14387 Type A); gas mask (EN 136), A2 type filter (EN 141, EN 143) or self-contained breathing apparatus (EN 139, EN 132).

b. Hand protection: Chemical resistant protective gloves (EN 374, EN 388). Suitable material also with prolonged, direct contact (recommended: Protective index 6, corresponding > 480 minutes of permeation time according to EN 374): butyl rubber (butyl) or viton.

Check the tightness before wear. Gloves should be well cleaned before being removed then stored in a well ventilated location. Pay attention to skin care. Textile or leather gloves are completely unsuitable. Use additional heat protection gloves when handling hot molten masses (EN 407), e. g. of textile or leather.

c. Eye protection: goggles/face protections (EN 166). Wear glasses with side protection. If the eyes may potentially come in contact with the liquids, chemical safety goggles are necessary.

d. Skin protection: The substance can be absorbed through the skin. Wear suitable, flameproof antistatic protective clothing (EN 340) and protective shoes (EN 345, EN 346, EN 347). The protection of clothing should be solvent resistant.

Remarks: Proper personal hygiene. Before a break wash hands and face with soap and water, take a shower after work if applicable. Apply fatty skin-care products after washing. Take off immediately all contaminated clothing. Before a break it might be necessary to change clothes. If at risk of contamination, foods, tobacco, beverages and other articles of consumption must not be stored or consumed at work areas. Special areas are to be designated for these purposes. In NO case drink any alcohol. Provide washrooms with showers and rooms with separate storage for street clothing and work clothing if there is a possibility of contamination of work clothes.

Stability and reactivity

Stability and reactivity

Conditions to avoid: Mineral acids (e.g. sulphuric acid, phosphoric acid etc.), organic acids (e.g. acetic acid, citric acid, etc.), oxidizing agents (e.g. perchlorates, nitrates, etc.), sodium and calcium hypochlorite, glass-wool insulation. Reacting with slightly alkaline mineral acids, the product forms water-soluble amine salts. These salts resist oxidation better than “basic” amines. Reactions with peroxides may result in the quick decomposition of peroxides.

Hazardous decomposition products: The product is stable, no spontaneous polymerization occurs.

It is oxidized when in contact with air, which generates coloured paint and tar. This reaction takes place the quickest at high temperatures, e.g. when the substance is melt.  

Disposal considerations

Disposal considerations

Dispose in compliance with environmental regulations, waste disposal regulations and regional local authority requirements.

Product: Useless product, any by-products and residues shall be treated as dangerous wastes. Collection vessels must be clearly labelled with a systematic description of their contents and hazard symbol and the R and S phrases. Store the vessels in a well-ventilated location. Entrust them to the appropriate authorities for disposal.

Package: After containers have been emptied as thoroughly as possible (e.g. by pouring, scraping or draining until "drip-dry"), they can be sent to an appropriate collection point. After cleaning with hot water and/or steam it can be recycled. Packs that cannot be cleaned should be disposed of in the same manner as the contents.
