Guidance on Safe Use

First-aid measures

Description of first aid measures:

Pay attention to self-protection. Remove victims from hazardous area. Immediately remove soiled or soaked clothing and remove it to a safe distance. Keep victim warm, in a stabilized position and covered. Do not leave victims unattended. If the casualty is unconscious: Place the victim in the recovery position.

Skin contact:

Wash off affected area immediately with plenty of water for at least 15 minutes. If symptoms persist, consult a physician for treatment.

Ingestion:

Rinse out mouth. Immediately give large quantities of water to drink. Consult a physician immediately.

Most important symptoms and effects, both acute and delayed:

Indication of any immediate medical attention and special treatment needed:

The initial focus is only on the local action, possibly characterized by a progressive tissue irritation. In the eye, irritating liquids cause, depending on the intensity of exposure, irritation of the conjunctiva and, in exceptional cases, damage to the cornea. There is a danger of blindness if corneas are damaged! Superficial irritations and only infrequent damage with ulcerations develop on the skin. An irritation of the mucous membranes may develop and lead to coughing after inhalation.

Fire-fighting measures

Suitable extinguishing media:

CO2, foam, dry powder, water spray

Unsuitable extinguishing media:

high volume water jet

Special hazards arising from the substance or mixture:

Hazardous fumes in fires, specific to the product: Carbon monoxide, nitrogen oxides (NOx), further toxic gases/vapours

Special protective equipment for fire-fighters:

wear a self contained respiratory apparatus. Wear suitable protective clothing.

Advice for firefighters:

Water used to extinguish fire should not enter drainage systems, soil, or stretches of water Ensure there are sufficient retaining facilities for water used to extinguish fire. Contaminated fire-extinguishing water must be disposed of in accordance with the regulations issued by the appropriate local authorities. Fire residues should be disposed of in accordance with the regulations.

Retention of fire-extinguishing water in Germany: see FireExtinguishing Water Retention Directive "LoeRueRL":

Accidental release measures

Personal precautions, protective equipment and emergency procedures:

Wear personal protective equipment.

Environmental precautions:

Prevent product from entering drains. Do not allow entrance in sewage water, soil or stretches of water.

Methods and material for containment and cleaning up:

Take up mechanically or with an absorbent material. Suitable binder: sand (for damming up), universal absorbent, ground limestone, vermiculite

Handling and storage

Handling:

Precautions for safe handling:

Observe the rules usually applicable when handling chemicals. Wear personal protective equipment. Use permissible in closed systems only.

Exposure controls / personal protection

Control parameters:

Engineering measures:

Provide for good ventilation if vapours/aerosols are formed. Refill and handle product only in closed system. Leak detection recommended Wastewater can be added to a biological wastewater treatment plant. Minimization of emissions by means of suitable technical measures such as flanges and valves with low leakage rates, recirculation of vapours. All precautionary measures indicated have to be observed.

Exposure controls:

The substance must be handled under strictly controlled conditions in accordance with Article 17/18 of the REACH Ordinance.

Personal protective equipment:

Respiratory protection:

In case of dusts/vapours/aerosols being formed or if the limit values like TLV are exceeded: use respiratory equipment with suitable filter or wear a self contained respiratory apparatus

Hand protection:

Accidental release measures:

suitable protective gloves: Glove material butyl-rubber

Material thickness: 0,5 mm

Break through time: > 480 min

Method: DIN EN 374

Glove material: Polychloroprene (PCP), PVC

Material thickness: 0,5 mm

Break through time: > 240 min

Method: DIN EN 374

Eye protection:

safety glasses with side-shields conforming to EN166

Hygiene measures:

Observe the rules usually applicable when handling chemicals. Wash off immediately in the event of contact with the skin (rinsing agent: glycol polyethylene 400), rinse off afterwards with copious amounts of water. No eating, drinking, smoking, or snuffing tobacco at work. Wash face and/or hands before break and end of work. Take off clothing and shoes contaminated with product. Clean before reuse.

Protective measures:

The personal protective equipment used must meet the requirements of directive 89/686/EEC and amendments (CE certification). All precautionary measures indicated have to be observed. Risk assessment and risk monitoring of all work places required. Health, Safety and Emergency Management System recommended. Regular safety training is a must. Written approval necessary in case of non-routine jobs, e.g. maintenance activities.

Stability and reactivity

Hazardous decomposition products: Decomposition products from hydrolysis in water, toxic gases/vapours, methanol

Further information:

decomposition with: oxidizing agents, alkalis, acids

Disposal considerations

Product:

With respect to local regulations, e.g. dispose of to suitable waste incineration plant. Strictly controlled conditions during disposal or treatment to air, wastewater and waste. Wastewater can be added to a biological wastewater treatment plant. Bring wastewater containing AOX for professional disposal.

Uncleaned packaging:

Do not reuse empty containers and dispose of in accordance with the regulations issued by the appropriate local authorities.

Waste Key Number:

The waste key number must be determined as per the European Waste Types List (decision on EU Waste Types List 2000/532/EC) in cooperation with the disposal firm / producing firm / official authority.
