N,N-dimethylbutylamine

Guidance on Safe Use

First-aid measures

First aider needs to protect himself.

If inhaled:       Move to fresh air. Keep patient warm and at rest. Call a physician immediately.

In case of skin contact: Take off all contaminated clothing immediately. Wash off with 3% acetic acid (e.g. food vinegar)

and plenty of water. Immediate medical treatment is necessary as untreated wounds from corrosion of the skin heal slowly and

with difficulty.

In case of eye contact: In case of eye contact, eventually remove contact lens, and rinse immediately with plenty of water,

also under the eyelids, for at least 15 minutes. Call a physician immediately.

If swallowed       : Call a physician immediately. Do not induce vomiting without medical advice.

Most important symptoms and effects, both acute and delayed:

Shortness of breath, spasm, Coughing

Aspiration may cause pulmonary oedema and pneumonitis. Ingestion gives rise to a risk of perforation of the oesophagus and stomach.

For physicians:

Treatment: Analogue to other alkaline substances. If ingested, irrigate the stomach. Later control for pneumonia and lung oedema. Treat skin and mucous membranes with antihistamine and corticoids. Symptoms of poisoning may appear several hours after contamination. Keep under medical supervision for

at least 48 hours.

Fire-fighting measures

Suitable extinguishing media: Alcohol-resistant foam, Dry powder,  Carbon dioxide (CO2), Water spray jet

Unsuitable extinguishing media: high volume water jet

Specific hazards during fire-fighting: Flash back possible over considerable distance. Vapours are heavier than air and

may spread along floors. Development of toxic combustion gases possible: Carbon monoxide (CO), Carbon dioxide (CO2),

Nitrogen oxides (NOx)

Special protective equipment for firefighters:  In the event of fire, wear self-contained breathing apparatus.

Cool containers/tanks with water spray. Keep people away from and upwind of spill/leak. Use extinguishing measures that

are appropriate to local circumstances and the surrounding environment. Please observe escape and rescue routes!

Accidental release measures

Personal precautions:  Avoid contact with eyes. Avoid inhalation of vapour or mist. Keep people away from and upwind of spill/leak.

Ensure adequate ventilation, especially in confined areas. Remove all sources of ignition.

Environmental precautions       : Prevent further leakage or spillage if safe to do so. Prevent spreading over a wide area (e.g. by containment

or oil barriers). Do not discharge product into the aquatic environment without pretreatment (biological treatment plant). Contain contaminated

water/firefighting water.

Methods for cleaning up: Soak up with inert absorbent material. Unsuitable material for picking up: Sawdust

If liquid has been spilt in large quantities clean up promptly by scoop or vacuum. Keep in suitable, closed containers for disposal.

Containers in which spilt substance has been collected must be adequately labelled. When picked up, treat material as prescribed under

heading "Disposal".

Handling and storage

Observe general rules of handling chemicals at industrial sites. Do not get on skin or clothing. Avoid contact with eyes. Avoid breathing vapours,

mist or gas. Handle and open container with care. Ensure that eyewash stations and safety showers are close to the workstation location.

Keep away from sources of ignition - refrain from smoking. Take necessary action to avoid static electricity discharge (which might cause

ignition of organic vapours). Observe the general rules of industrial fire protection. Geman Temperature class: T4

Hygiene measures: Do not eat, drink or smoke during work time. Keep away from food and drink. Clean hands and face during work intervals

and after work. Observe general rules of industrial hygiene.

Requirements for storage areas and containers: Keep containers tightly closed in a cool, well-ventilated place.

Protect from moisture. Keep under nitrogen.

Advice on common storage: Incompatible with strong acids and oxidizing agents.

German Storage class (TRGS 510): 3, Flammable liquids

Recommended storage temperature: -1 - 38°C

SpecialProvisions

Exposure controls / personal protection

Engineering measures: Apply technical measures to comply with the occupational exposure limits. This should be achieved by a good general extraction and -if practically feasible- by the use of a local exhaust ventilation. Use explosion-proof equipment.

Eye protection: Safety glasses with side-shields conforming to EN166. Tightly fitting safety goggles. If splashes are likely to occur, wear:

Face-shield

Hand protection: Choose gloves to protect hands against chemicals depending on the concentration and quantity of the hazardous substance and specific

to place of work. The selected protective gloves have to satisfy the specifications of the standard EN 374. Take note of the information given by the producerconcerning permeability and break through times, and of special workplace conditions (mechanical strain, duration of contact).

Suitable: Nitrile rubber gloves. PVC gloves.

Gloves must be inspected prior to use. Gloves should be discarded and replaced if there is any indication of degradation or chemical breakthrough.

Gloves must be rinsed thoroughly after use.

Skin and body protection:       Choose body protection in relation to its type, to the concen-tration and amount of dangerous substances, and to the specific

work-place. Long sleeved clothing.

Wear as appropriate: Impermeable protective clothing.

Suitable:

Protective clothing  Category III, type 3 - liquid-tight

Protective clothing  Category 3, type 6 - Limited splash-tight

Take off all contaminated clothing immediately. Wash contaminated clothing before re-use.

Respiratory protection: In the case of vapour formation use a respirator with an approved filter. Respiratory protection complying with DIN EN 14387.

Multi-purpose filter ABEK.

Stability and reactivity

Stable under recommended storage conditions. No decomposition if used as directed. In case of fire hazardous gases may be formed.

May react violently with strong acids and oxidizing substances.

Avoid heat, flames and sparks.

Avoid strong acids and oxidizing agents

Disposal considerations

Product: Dispose of contents/ container to an approved waste disposal plant. Observe local authority regulations

Contaminated packaging: Empty remaining contents. Can be used after re-conditioning. Packaging that cannot be cleaned should be disposed of as product waste.
