Guidance on Safe Use

First-aid measures

1 Description of first aid measures
Eyes: remove any contact lenses. Wash immediately with plenty of water for at least 15 minutes, opening the eyelids well. Consult a doctor if the problem persists.
Skin: take off contaminated clothing. Wash immediately and abundantly with water for at least 15 minutes. If irritation persists, consult a doctor. Wash the contaminated garments before reusing them.
Inhalation: take the person to fresh air. If breathing is difficult, call a doctor right away.
Ingestion: consult a doctor immediately. Induce vomiting only on medical advice. Do not give anything by mouth if the subject is unconscious and if not authorized by the doctor.

2 Most important symptoms and effects, both acute and delayed
No specific information on the symptoms and effects caused by the product is known.

3 Indication of any immediate medical attention and special treatment needed
Note to physicians: supportive care only is required for adult ingestion of less than a few grams of the product. For ingestion of larger amounts, maintain fluid and electrolyte balance and maintain adequate kidney function. Gastric lavage is only recommended for heavily exposed, symptomatic patients in whom emesis has not emptied the stomach. Hemodialysis should be reserved for patients with massive acute absorption, especially for patients with compromised renal function.

Fire-fighting measures

1 Extinguishing media
Suitable extinguishing media: the extinguishing media are traditional ones, that is carbon dioxide, powder and nebulized water.
Unsuitable extinguishing media: none.

 

2 Special hazards deriving from the mixture
Avoid breathing combustion products.

 

3 Advice for firefighters
General information: cool the containers with jets of water to avoid product decomposition and the development of substances potentially hazardous to health. Always wear full fire protection equipment. Collect the extinguishing water which must not be discharged into the sewers. Dispose of the contaminated water used for extinguishing and the residue of the fire according to current regulations.
Equipment: normal fire-fighting clothing, such as self-contained open-circuit compressed air breathing apparatus (EN 137), flame retardant suit (EN 469), flame retardant gloves (EN 659) and fire brigade boots (HO A29 or A30)

Accidental release measures

1 Personal precautions protective equipment and emergency procedures
Stop the loss if there is no danger.
Wear suitable protective equipment (including personal protective equipment referred to in section 8 of the safety data sheet) to prevent contamination of skin, eyes, and personal clothing. These indications are valid for both processing workers and emergency interventions.

 

2 Environmental precautions
Prevent the product from entering sewers, surface water, groundwater.

 

3 Methods and material for containment and cleaning up
Suck up the leaked product into a suitable container. Evaluate the compatibility of the container to be used with the product, checking SDS section 10. Absorb the remainder with inert absorbent material.
Provide sufficient ventilation of the place affected by the leak. The disposal of contaminated material must be carried out in accordance with the provisions of SDS point 13.

Handling and storage

1 Precautions for safe handling
Handle the product after consulting all the other sections of this safety data sheet. Avoid the dispersion of the product into the environment. Do not eat, drink, or smoke during use. Remove contaminated clothing and protective equipment before entering the eating area.

2 Conditions for safe storage, including any incompatibilities
No special handling precautions are required, however storage in a closed and dry place is recommended.
Keep only in the original container. Keep the containers tightly closed. Keep containers away from any incompatible materials, checking SDS section 10.
To preserve the integrity of the packaging:
• manipulate the bags based on the principle "first-in, first-out"
• tore in cool, dry, and well-ventilated place, away from strong reducing agents
• keep preferably at a temperature between 20°C and 35°C.
• avoid high air humidity
• avoid sunlight exposure
• avoid temperatures under -5 °C and over 40°C.

Exposure controls / personal protection

1 Control parameters
Occupational exposure limits: in the absence of national occupational exposure limit values an internal occupational exposure limit 5mg/m3 is recommended.

DNELs/PNECs: see LR dossier

 

2 Exposure controls
The use of adequate technical measures should always have priority over personal protective equipment, ensure good ventilation in the workplace through effective local aspiration.
For the choice of personal protective equipment, if necessary, ask your chemical suppliers for advice.
Personal protective equipment must bear the CE marking which certifies their compliance with current regulations. Provide an emergency shower with face and eye basin.
Hand protection: if contact with the product is protract, hands protection with work gloves is recommended (ref. Standard EN 374). For the final choice of the material of the work gloves it is necessary to consider compatibility, degradation, breakage time and permeability. Remember that latex gloves can be give sensitize reaction.
Skin protection: wear category I work clothes with long sleeves and safety footwear for professional use (ref. Regulation 2016/425 and standard EN ISO 20344). Wash with soap and water after removing protective clothing.
Eye protection: it is recommended to wear airtight safety goggles (ref. Standard EN 166).
Respiratory protection: not necessary, unless otherwise indicated in the chemical risk assessment.
Environmental Exposure Controls: Emissions from production processes, including from production equipment, should be controlled for compliance with environmental protection legislation.
