Diquat dibromide

Guidance on Safe Use

First-aid measures

DESCRIPTION OF FIRST AID MEASURES

- General advice: Have the product container, label or Safety Data Sheet with you when calling the emergency number, a poison control center or physician, or going for treatment.

- If inhaled: Move the victim to fresh air. If breathing is irregular or stopped, administer artificial respiration. Keep patient warm and at rest. Call a physician or poison control centre immediately.

- In case of skin contact: Take off all contaminated clothing immediately. Wash off immediately with plenty of water. If skin irritation persists, call a physician. Wash contaminated clothing before re-use.

- In case of eye contact: Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. Remove contact lenses. Immediate medical attention is required.

- If swallowed: If swallowed, seek medical advice immediately and show this container or label. Do NOT induce vomiting.

MOST IMPORTANT SYMPTOMS AND EFFECTS, BOTH ACUTE AND DELAYED

- Symptoms: inflammation of the mouth, throat and oesophagus Gastrointestinal discomfort Diarrhoea.

INDICATION OF ANY IMMEDIATE MEDICAL ATTENTION AND SPECIAL TREATMENT NEEDED

- Treatment: Administer either activated charcoal (100 g for adults or 2 g/kg body weight in children) or Fuller's Earth (15 % solution; 1 litre for adults or 15 mL/kg body weight in children).

- Note: The use of gastric lavage without administration of an adsorbent has not shown any clinical benefit.

- Eye contact: Severe damage may be caused by apparently trivial contact and healing may be delayed. Medical supervision should continue until complete healing has occurred.

Fire-fighting measures

EXTINGUISHING MEDIA

- Suitable extinguishing media: Extinguishing media - small fires Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide. Extinguishing media - large fires Alcohol-resistant foam or water spray.

- Unsuitable extinguishing: Do not use a solid water stream as it may scatter and spread fire.

SPECIAL HAZARDS ARISING FROM THE SUBSTANCE OR MIXTURE

- Specific hazards during firefighting: As the product contains combustible organic components, fire will produce dense black smoke containing hazardous products of combustion. Exposure to decomposition products may be a hazard to health.

ADVICE FOR FIREFIGHTERS

- Special protective equipment for firefighters: Wear full protective clothing and self-contained breathing apparatus.

- Further information: Do not allow run-off from fire fighting to enter drains or water courses. Cool closed containers exposed to fire with water spray.

Accidental release measures

PERSONAL PRECAUTIONS, PROTECTIVE EQUIPMENT AND EMERGENCY PROCEDURES

- Personal precautions: Refer to protective measures listed further below.

ENVIRONMENTAL PRECAUTIONS

- Environmental precautions: Prevent further leakage or spillage if safe to do so. Do not flush into surface water or sanitary sewer system. If the product contaminates rivers and lakes or drains inform respective authorities.

METHODS AND MATERIAL FOR CONTAINMENT AND CLEANING UP

- Methods for cleaning up: Contain spillage, and then collect with non-combustible absorbent material, (e.g. sand, earth, diatomaceous earth, vermiculite) and place in container for disposal according to local / national regulations. Clean contaminated surface thoroughly. Clean with detergents. Avoid solvents. Retain and dispose of contaminated wash water.

Handling and storage

PRECAUTIONS FOR SAFE HANDLING

- Advice on safe handling: Avoid contact with skin and eyes. When using do not eat, drink or smoke. For personal protection see further below. Spray solutions should not be mixed, stored or applied in containers other than plastic, plastic-lined steel, stainless steel or fiberglass.

CONDITIONS FOR SAFE STORAGE, INCLUDING ANY INCOMPATIBILITIES

- Requirements for storage areas and containers: No special storage conditions required. Keep containers tightly closed in a dry, cool and well-ventilated place. Keep out of the reach of children. Keep away from food, drink and animal feedingstuffs.

SPECIFIC END USE(S)

Specific use(s): Active substance for use in plant protection products.

SPECIAL PRECAUTIONS FOR USER
- The transport classification(s) provided herein are for informational purposes only, and solely based upon the properties of the unpackaged material as it is described within this Safety Data Sheet. Transportation classifications may vary by mode of transportation, package sizes, and variations in regional or country regulations.

TRANSPORT IN BULK ACCORDING TO ANNEX II OF MARPOL AND THE IBC CODE
- Not applicable for product as supplied.

Exposure controls / personal protection

CONTROL PARAMETERS

- Contains no substances with occupational exposure limit values.

ENGINEERING MEASURES

- Containment and/or segregation is the most reliable technical protection measure if exposure cannot be eliminated.

- The extent of these protection measures depends on the actual risks in use.

- Maintain air concentrations below occupational exposure standards. Where necessary, seek additional occupational hygiene advice.

EYE PROTECTION

- Tightly fitting safety goggles.

- Always wear eye protection when the potential for inadvertent eye contact with the product cannot be excluded.

- Use eye protection according to EN 166.

HAND PROTECTION

- Material: Nitrile rubber

- Break through time: > 480 min

- Glove length: 0.5 mm

- Remarks: Wear protective gloves. The choice of an appropriate glove does not only depend on its material but also on other quality features and is different from one producer to the other. Please observe the instructions regarding permeability and breakthrough time which are provided by the supplier of the gloves. Also take into consideration the specific local conditions under which the product is used, such as the danger of cuts, abrasion, and the contact time. The break through time depends amongst other things on the material, the thickness and the type of glove and therefore has to be measured for each case. Gloves should be discarded and replaced if there is any indication of degradation or chemical breakthrough. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.

SKIN AND BODY PROTECTION:

- Choose body protection in relation to its type, to the concentration and amount of dangerous substances, and to the specific work-place.

- Remove and wash contaminated clothing before re-use.

- Wear as appropriate: Impervious clothing.

RESPIRATORY PROTECTION:

- When workers are facing concentrations above the exposure limit they must use appropriate certified respirators.

- Suitable respiratory equipment: Respirator with a particle filter (EN 143)

- The filter class for the respirator must be suitable for the maximum expected contaminant concentration (gas/vapour/aerosol/particulates) that may arise when handling the product. If this concentration is exceeded, self- contained breathing apparatus must be used.

- Filter type: Particulates type (P)

PROTECTIVE MEASURES

- The use of technical measures should always have priorit
