For substances see 3.1.
In case of accident or if you feel unwell, seek medical advice immediately (show the label where possible). Never give anything by mouth to an unconscious person. Place patient in recovery position and ensure airway patency.
Ventilate the premises. Inhale fresh air. If difficulties with breathing do not stop, search for medical help.
Areas of the body that have come into contact with the product must be rinsed immediately with plenty of running water. If symptoms develop and persist, seek medical attention.
Immediately flush eyes with plenty of water while keeping eyelids apart (at least 15 minutes). Consult a physician immediately! Recommendation (based on practical experience): wash with plenty of water or with 3% boric acid solution.
Rinse mouth thoroughly with water. Drink 2 glasses of water. Do not induce vomiting! Consult a physician.
Intoxication, vertigo, headache, nausea.
Itching, redness, pain.
Prolonged or repeated exposure causes slight skin inflammation: signs/symptoms: localised redness, swelling, itching and dryness.
Redness, tearing, pain.
Symptoms may include: rubescence, edema, pain and lachrymation.
May cause abdominal discomfort.
Signs and symptoms: headache, dizziness, fatigue, confusion, drowsiness, salivation, abdominal convulsion, weakness, diarrhoea, vomiting, unconsciousness, paralyse breathing.
Use the usual extinguishing measures (carbon dioxide (CO2), dry chemical, foam; water spray)
Full water jet.
In case of fire or heating do not breathe fumes/vapours.
Select according to conditions and other factors.
Use personal protective equipment (Section 8). Avoid contact with the eyes and skin.
Ensure adequate ventilation.
Do not allow product to reach water/drains/sewage systems and ground water. If accidental large entry into water or ground occurs, inform responsible authorities.
Absorb with inert material (sand, flinstone (diatomite soil), universal binder, sawdust). Pick up mechanically and remove it in accordance with regulation.
See also Sections 8 and 13.
Ensure adequate ventilation.
Avoid contact with skin and eyes. Do not breathe vapours/mist. Do not eat, drink or smoke while working. Use good personal hygiene practices – wash hands at breaks and when done working with material.
Keep in cool and well ventilated area. Keep in tightly closed container.
