Zinc bis(dibutyldithiocarbamate)

Guidance on Safe Use

First-aid measures

General information: No alcohol after contact with product.

After inhalation:

Move exposed person to fresh air. Keep person warm and at rest. If not breathing, if breathing is irregular or if respiratory arrest occurs, provide artificial respiration or oxygen by trained personnel. It may be dangerous to the person providing aid to give mouth-to-mouth resuscitation. Get medical attention if adverse health effects persist or are severe. If unconscious, place in recovery position and get medical attention immediately. Maintain an open airway. Loosen tight clothing such as a collar, tie, belt or waistband. In case of inhalation of decomposition products in a fire, symptoms may be delayed.

The exposed person may need to be kept under medical surveillance for 48 hours.

After skin contact:

Wash off immediately with soap and plenty of water removing all contaminated clothes and shoes. If skin irritation persists, call a physician.

After eye contact:

Immediately flush eyes with plenty of water, occasionally lifting the upper and lower eyelids. Check for and remove any contact lenses if easy to do. Continue to rinse for at least 10 minutes. Get medical attention.

After swallowing:

Wash out mouth with water. Move exposed person to fresh air. Keep person warm and at rest. If material has been swallowed and the exposed person is conscious, give small quantities of water to drink. Stop if the exposed person feels sick as vomiting may be dangerous. Do not induce vomiting unless directed to do so by medical personnel. If vomiting occurs, the head should be kept low so that vomit does not enter the lungs. Get medical attention if adverse health effects persist or are severe.

Never give anything by mouth to an unconscious person. If unconscious, place in recovery position and get medical attention immediately. Maintain an open airway. Loosen tight clothing such as a collar, tie, belt or waistband.

Do not touch or walk through spilled material. Provide adequate ventilation. Avoid the generation of dust. Avoid contact with skin, eyes and clothing. Put on appropriate personal protective equipment, e.g. in case of dust generation wear a respirator conforming to EN140 with Type A/P2 filter or better. Wear chemically resistant gloves (tested to EN374) in combination with intensive management supervision controls. Use suitable eye protection. Wear suitable coveralls to prevent exposure to the skin.

Environmental precautions:

Very toxic to aquatic organisms. Avoid dispersal of spilt material and runoff and contact with soil, waterways, drains and sewers. Inform the relevant authorities if the product has caused environmental pollution (sewers, waterways, soil or air).

Methods and material for containment and cleaning up:

Large spill: Move containers from spill area. Prevent entry into sewers, water courses, basements or confined areas. Vacuum or sweep up material and place in a designated, labelled waste container. Dispose of via a licensed waste disposal contractor.

Small spill: Move containers from spill area. Vacuum or sweep up material and place in a designated, labeled waste container. Dispose of via a licensed waste disposal contractor.

Handling and storage

Precautions for safe handling

Avoid breathing dust.

Avoid contact with eyes and skin.

Put on appropriate personal protective equipment. Eating, drinking and smoking should be prohibited in areas where this material is handled, stored and processed. Workers should wash hands and face before eating, drinking and smoking. Persons with a history of skin sensitization problems should not be employed in any process in which this product is used. Do not get in eyes or on skin or clothing. Do not ingest. Avoid release to the environment. Keep in the original container or an approved alternative made from a compatible material, kept tightly closed when not in use. Empty containers retain product residue and can be hazardous.

Information about fire - and explosion protection:

Avoid dust accumulation. Dust/air mixtures may ignite violently upon exposure to sparks or sources of

ignition. Kst: 197 bar m/s. Maximum corrected explosion pressure: 7.3 bar.

Conditions for safe storage, including any incompatibilities

Storage

Requirements to be met by storerooms and receptacles

Store only in the original receptacle.

Store in accordance with local regulations. Store in a dry and cool place. Keep container tightly closed until ready for use. Containers that have been opened should be carefully closed. Do not store in unlabelled containers. Use appropriate containment to avoid environmental contamination.

Information about storage in one common storage facility:

Do not store together with oxidizing and acidic materials.

Further information about storage conditions: Keep container tightly sealed.

Exposure controls / personal protection

Additional Information about design of technical facilities

If this product contains ingredients with exposure limits, personal, workplace atmosphere or biological monitoring may be required to determine the effectiveness of the ventilation or other control measures and/or the necessity to use respiratory protective equipment. Reference should be made to European Standard EN 689 for methods for the assessment of exposure by inhalation to chemical agents and national guidance documents for methods for the determination of hazardous substances.

Local exhaust ventilation is strongly recommended.

Provide extract ventilation to material transfer points and other openings. Minimise exposure by partial enclosure of the operation or equipment and provide extract ventilation at openings. Ensure material transfers are under containment or extract ventilation. Handle in a fume cupboard or under extract ventilation.

Personal protective equipment:

General protective and hygienic measures:

Keep away from foodstuffs, beverages and feed.

Wash hands, forearms and face thoroughly after handling chemical products, before eating, smoking and using the lavatory and at the end of the working period. Appropriate techniques should be used to remove potentially contaminated clothing. Wash contaminated clothing before reusing. Ensure that eyewash stations and safety showers are close to the workstation location.

Respiratory protection:

Use a properly fitted, air-purifying or air-fed respirator complying with an approved standard if a risk assessment indicates this is necessary. Respirator selection must be based on known or anticipated exposure levels, the hazards of the product and the safe working limits of the selected respirator.

Protection of hands:

Chemical-resistant, impervious gloves complying with an approved standard (EN374) and considering the permeation breakthrough time should be worn at all times when handling chemical products if a risk assessment indicates this is necessary.

After contamination with product change the gloves immediately and dispose of them according to relevant national and local regulations.

Material of gloves e.g. nitrile rubber coated textile gloves

Penetration time of glove material:

The exact break through time has to be found out by the manufacturer of the protective gloves and has to be observed.

Eye protection:

Tightly sealed goggles

Body protection:

Wear suitable protective equipment. Choose body protection according to the amount and concentration of the dangerous substance at the work place.

Disposal considerations

Waste treatment methods

Recommendation

Examine possibilities for re-utilisation. Product residues and uncleaned empty containers should be packaged, sealed, labelled, and disposed of or recycled according to relevant national and local regulations. Where large quantities are concerned, consult the supplier. When uncleaned empty containers are passed on, the recipient must be warned of any possible hazard that may be caused by residues. For disposal within the EC, the appropriate code according to the European Waste List (EWL) should be used. It is among the tasks of the polluter to assign the waste to waste codes specific to industrial sectors and processes according to the European Waste List (EWL).

European waste catalogue

According to the European Waste Catalogue, Waste Codes are not product specific, but application specific.

The user based on the application for which the product was used should assign waste codes.

Uncleaned packaging:

Recommendation Disposal must be made according to official regulations.
