Guidance on Safe Use

First-aid measures

General advice: Immediately remove contaminated clothing and shoes. First aid personnel should pay attention to their own safety. Wear protective gloves to avoid skin contamination.

Remove victims out of the danger area without endangering your own safety.

In case of skin contact: The contaminated parts of the body must be wiped off and preferably washed with a cleanser based on polyethylene glycol or with plenty of warm water and soap. (The extent of adsorption can be reduced by using water at the lowest temperature possible.) Apply protective bandage with sterile gauze. 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. Wash clothing before reuse. Clean shoes thoroughly before reuse.

Note: The substance is often transported as melt. It can cause burn when touched. In this case, immerse the burnt skin surface into cold water or flush it with cold water.

In case of eye contact: Wash affected eyes for several minutes under running water, seek medical attention.

If inhaled: Keep patient calm, remove to fresh air, seek medical attention. Turn the head of the exposed person to the side. 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.

If swallowed: Rinse mouth immediately. Seek medical advice. DO NOT induce vomiting. Gastrolavage or vomiting practices may be performed exclusively under the control of medical personnel. Never give anything by mouth to an unconscious person.

Notes to physician: No specific antidote known. 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

Suitable extinguishing media: extinguishing powder, foam, carbon dioxide (CO2); in case of large fires water spray can be used. 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 chemical-protective clothing. Fire-fighters should wear appropriate protective equipment and self-contained breathing apparatus (SCBA) with a full face-piece operated in positive pressure mode. PVC boots, gloves, safety helmet and protective clothing should be worn.

Special protective equipment for fire-fighters: Heat and fire-proof suit (ISO/DIS 11612).

Other information: Fire hazard class: “D” (moderately flammable) in Hungary

Instructions: Dispose off fire debris and contaminated extinguishing water in accordance with official regulations. Extinguishing water may be toxic to aquatic organisms. Do not allow extinguishing media enter the soil, ground-water  and surface waters. Fire in the vicinity poses risk of pressure build-up and rupture. Containers at risk from fire should be cooled with water and, if possible, removed from the danger area. Shut off sources of ignition. Stay on the upwind side. In the event of fire and/or explosion do not breathe in any fumes.

Accidental release measures

Personal precautions: Avoid contact with skin, eyes and clothing. Immediately contact the emergency personnel. Evacuate the affected area. Areas of leakage must be closed down if this can be done without personal injury. Keep upwind in order to avoid the inhalation of vapours. Clean-up should only be performed by trained personnel. People dealing with major spillages should wear full protective clothing including respiratory protection.

Keep away from sources of ignition. Provide adequate ventilation. Keep unauthorized persons away.

Environmental precautions: Do not discharge into drains/surface waters/groundwater.

Avoid dispersal of spilt material and runoff and contact with soil, waterways, drains and sewers. 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.

It is a potential hazard to the surrounding atmosphere if larger quantities of the substance escape. Inform the 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: Ensure thorough ventilation of stores and work areas. Refill and handle product only in closed systems; vented air should pass scrubbers / filters before release to the environment. Prevent electrostatic charge, sources of ignition should be kept well clear, fire extinguishers should be kept handy. Handling only by employees trained in properties of the material and trained in proper use of personal protective equipment, with emphasis on disposal of contaminated gloves and clothing. Before maintenance work, concerned storage devices and transport lines must be flushed clear; cleaning liquid has to be disposed of properly, avoidance of contamination by cleaning liquid has to be ensured.

Handle the material with care. 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 is required. These locations must be clearly signposted. When handling excessive amounts of the substance an emergency shower is required. 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. Take organizational measures to limit any potential exposure, e.g. by limiting the exposure time for critical tasks like sampling (should not take over 5 minutes per week). Keep equipment clean. The floor must be solvent resistant. Make sure that all pipelines, tanks and equipment are leak-proof. Organize work procedures so that workers should not be exposed to the effects of products. The substance must not be present at workplaces in quantities

above as required for work to be progressed. 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: Keep away from food, drink and animal feeding stuffs. Keep containment tightly closed. 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) - 0.7 mm coating thickness, nitrile rubber >= 1.3 mm coating thickness or fluoroeöastomer nitrile shell, at least 0.425 mm thickness.

neoprene, viton or fluor-elastomer safety gloves with polyacryl-nitrile coating. 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, EN 170). 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, EN 343) 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.

Environmental exposure controls: No available information.

Stability and reactivity

Hazardous reactions:

Reacts with acids. The progress of reaction is exothermic.

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

Waste code in accordance with the European waste catalog (EWC): 07 01 08

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.
