Guidance on Safe Use

First-aid measures

4.1. Description of first aid measures

In case of doubt or in the presence of symptoms contact a physician, and show him/her the material safety data sheet. In case of severe symptoms, call your local health care emergency number. Call a poison control center in order to receive toxicological advice for the clinical management of poisoning. Do not administer anything by mouth to an unconscious person.

Inhalation

Move the person to fresh air. In the case of respiratory symptoms (cough, dyspnea) place the person in a semi-seated position and administer oxygen. Provide artificial respiration if the person is not breathing.

Skin contact

Flush the skin with copious amounts of water (and soap, if possible) for at least 15 minutes. Consult a physician if there are symptoms of skin irritation and/or pain.

Eye contact

Remove contact lenses, if present and easy to do. Flush the eyes, kept open, with copious amounts of running water for at least 15 minutes. Consult a physician, especially if there are symptoms of eye irritation and/or pain.

Ingestion

Do not induce emesis. Do not administer anything by mouth unless advised to do so by a poison control center. Rinse the mouth and consult a physician.

4.2. Most important symptoms and effects, both acute and delayed

Most important symptoms and effects, both acute and delayed, are described in the end-point study records.

4.3. Indication of any immediate medical attention and special treatment needed

Need for immediate medical attention

If the victim has severe symptoms, immediately call your local health care emergency number to request the intervention of a physician. Refer to each case a poison control center for advice and medical toxicology specialist from the early stages of the rescue. Consult a physician if in any case any symptoms, even mild, persists.

Special treatment needed and antidotes to be available on the workplace

Freshwater for washing skin and eye. Oxygen. Activated charcoal, to be administered after toxicological advice.

Personal protective equipment for first aid responders

Wear appropriate protective equipment to prevent the contamination of the first aid responder from the victim.

SPECIAL PROTECTIVE EQUIPMENT FOR FIRE-FIGHTERS

Hardhat with visor, fireproof clothing (fireproof jacket and trousers with straps around arms, legs and waist), work gloves (fireproof, cut proof and dielectric), a depressurized mask with facemask covering the whole of the operator`s face or a self-respirator (self-protector) in the event of large quantities of fume.

(b) send away individuals who are not suitably equipped.

6.1.2. For emergency responders

(a) do not handle damaged containers or leaked product before donning appropriate protective gear (Section 8 of the safety data

    sheet) to prevent any contamination of skin, eyes and personal clothing;

(c) if there are no contraindications, spray powder with water to prevent the formation of dust and provide sufficient ventilation.

6.2. Environmental precautions

The product must not penetrate the sewer system, surface water, ground water and neighboring areas.

6.3. Methods and material for containment and cleaning up

6.3.1. Appropriate advice on how to contain a spill

(a) make sure the leakage site is well aired.

6.3.2. Appropriate advice on how to clean up a spill

(a) use spark proof mechanical tools to collect the leaked product and place in a plastic container;

(b) if there are no contraindications, use jets of water to eliminate product residues.

6.3.3. Any other information relating to spills and releases,including advice on inappropriate containment or clean up techniques

(a) contaminated material should be disposed of in compliance with the national provisions.

Handling and storage

7.1. Precautions for safe handling

7.1.1. Protective measure

Measures to prevent fire

(a) eliminate sources of ignition (cigarettes, flames, sparks, etc.);

(b) wear antistatic cloths and shoes when handling this substance;

(c) use antistatic primary packagings;

(d) avoid shaking the powder or creating dust clouds;

(e) ground and bound equipment; work as much as possible with inertization systems to avoid the formation of potentially explosive atmospheres;

(f) use spark proof mechanical tools to collect the leaked product.

Measures to prevent aerosol and dust generation

(a) avoid shaking packagings when filling/empting them;

(b) keep containers tightly sealed when not in use.

Measures to protect the environment

(a) general ventilation;

(b) LEV;

(c) filters or water scrubbers on exhaust ventilation.

7.1.2. Advice on general occupational hygiene

(a) not to eat, drink and smoke in work areas;

(b) to wash hands after use;

(c) to remove contaminated clothing and protective equipment before entering eating areas.

7.2. Conditions for safe storage, including any incompatibilities

Technical measures and storage conditions

Store away from oxidizing agents and strong alkalies.

The substance should be stored in a manner to prevent degradation, contamination, and cross-contamination, keeping material in properly labeled tightly closed containers.
