| B | Some substances (acids, bases, etc.) are placed on the market in aqueous solutions at various concentrations and, therefore, these solutions require different classification and labelling since the hazards vary at different concentrations. In Part 3 entries with Note B have a general designation of the following type: "nitric acid … %". In this case the supplier must state the percentage concentration of the solution on the label. Unless otherwise stated, it is assumed that the percentage concentration is calculated on a weight/weight basis. |

Remove contaminated clothing. Never give anything by mouth to an unconscious person. Place patient in recovery position and ensure airway patency. When in doubt or if feeling unwell seek medical assistance. Show the safety data sheet and label to the physician.
No action shall be taken involving any personal risk or without suitable training. When it is suspected, that there may still be harmful vapours/fumes present in the air, respiratory protection (mask; self contained breathing apparatus) must be used. Wash contaminated clothing with water before removing or use gloves. It may be dangerous to the person providing aid to give mouth-to-mouth resuscitation.
Remove patient to fresh air - move out of dangerous area. In case of unconsciousness bring patient into stable side position and seek medical attention. Seek medical help immediately. If breathing is irregular or respiratory arrest occurs provide artificial respiration. Keep at rest in a position comfortable for breathing.
Take off all contaminated clothing. Wash affected skin areas thoroughly with plenty of water and soap. If symptoms develop and persist, seek medical attention.
Immediately flush eyes with running water, keeping eyelids apart. After 5 minutes of rinsing, remove contact lenses, if present, and continue rinsing. Consult a physician immediately!
Do not induce vomiting! Rinse mouth and drink plenty of water (only if the person is conscious). If vomiting occurs, the patient should hold the head lower than the hips, because it reduces the possibility of aspiration. Immediately consult a doctor. Show the physician the safety data sheet or label.
Excessive exposure to spray mist, fog, or vapours may cause respiratory irritation.
Symptoms may include cough, sneezing, nasal discharge, headache, hoarseness, nose and throat pain.
May cause localised redness, swelling, itching, intense pain, blistering, ulceration and tissue destruction.
Redness, pain, burning sensation, tearing, can cause permanent damage to the eyes.
May cause corneal injury.
May cause abdominal discomfort.
May cause nausea/vomiting and diarrhea.
Harmful to health.
If ingested, may cause burns of the mouth and throat, as well as perforation of the esophagus and stomach.
Treat symptomatically. Have eye wash facilities in place close to the operators’ work area to provide immediate first aid prior to medical attention. Severe cases of eye contact and ingestion should receive medical attention immediately.
Carbon dioxide. Dry chemical powder. Water spray. Alcohol resistant foam. Use extinguishing measures that are appropriate to local circumstances and the surrounding environment.
Full water jet.
In case of a fire toxic gases can be generated; do not inhale gases/smoke.
In case of fire or heating do not breathe fumes/vapours. Cool containers at risk with water spray. If possible remove containers from endangered area. No action shall be taken involving any personal risk or without suitable training.
Firefighters should wear appropriate protective clothing for firefighters (including helmets, protective boots and gloves) (EN 469) and self-contained breathing apparatus (SCBA) with a full face-piece (EN 137).
Contaminated firefighting water must be disposed of in accordance with the regulations; do not allow to reach the sewage system.
Use personal protective equipment (Section 8).
Ensure adequate ventilation. Keep away from sources of ignition and/or heat; No smoking! Prevent access to unprotected personnel. No action shall be taken involving any personal risk or without suitable training. Evacuate the danger zone. Do not breathe vapour or mist. Avoid contact with skin, eyes and clothing.
During intervention, use personal protective equipment (Section 8).
Do not allow product to reach water/drains/sewage systems or permeable soil. In case of release into the environment, inform the relevant authorities.
Stem the spill if this does not pose risks.
Absorb product (with inert material), collect it in special container and dispose it to a licensed hazardous-waste disposal contractor. Prevent release into the sewer, water, basements or confined areas. Dispose in accordance with applicable regulations (see Section 13).
See Section 7: safe handling. See Section 11 for additional information on health hazards. Dispose of in accordance with the instructions from Section 13.
See also Sections 8 and 13.
Ensure adequate ventilation. Take precautionary measures against static discharges. Keep away from sources of ignition - no smoking. Use spark-proof tools.
Use general or local exhaust ventilation to prevent inhaling vapours and aerosols.
Do not discharge into drains, surface water and soil. After use immediately close container tightly.
Do not eat, drink or smoke while working. Do not breathe vapours/mist. Use good personal hygiene practices – wash hands at breaks and when done working with material. Avoid contact with skin, eyes and clothes. Remove contaminated clothes and wash them before reuse. Wear suitable protective equipment; see Section 8.
Protect from open fire, heat and direct sunlight. Keep away from food, drink and animal feeding stuffs. Keep in a cool, dry and well ventilated place. Store below 30°C. Keep away from incompatible products (see section 10).
Store only in original container.
Close opened containers after use. Put the containers upright to prevent from leaking. Do not store in unlabelled containers.
