Hazard pictograms
Corrosion | Exclamation mark | Health Hazard |
Hazard statements
Harmful if swallowed. Causes severe skin burns and eye damage. May cause an allergic skin reaction. Causes damage to organs: blood or blood-forming organs |
Prevention
Do not breathe dust/fume/gas/mist/vapors/spray. Wear protective gloves, protective clothing, and eye/face protection. Do not eat, drink or smoke when using this product. Wash thoroughly after handling. Contaminated work clothing must not be allowed out of the workplace.
Response
IF INHALED: Remove person to fresh air and keep comfortable for breathing. IF ON SKIN (or hair): Take off immediately all contaminated clothing. Rinse skin with water/shower. IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Immediately call a POISON CENTER or doctor/physician. If skin irritation or rash occurs: Get medical advice/attention. Wash contaminated clothing before reuse. IF SWALLOWED: Rinse mouth. Do NOT induce vomiting. Specific treatment (see Notes to Physician on this label).
Storage
Store locked up.
Disposal
Dispose of contents/container in accordance with applicable local/regional/national/international regulations. Notes to Physician: Overexposure to this product may result in methemoglobinemia. Methemoglobinemia may be clinically suspected by the presence of clinical "cyanosis" in the presence of a normal PaO2 (as obtained by arterial blood gases). Routine pulse oximetry may be inaccurate for monitoring oxygen saturation in the presence of methemoglobinemia, and should not be used to make the diagnosis of this disorder. If the patient is symptomatic or if the methemoglobin level is >20%, specific therapy with methylene blue should be considered as part of the medical management.
2.3 Other hazards
May cause chemical gastrointestinal burns. 25% of the mixture consists of ingredients of unknown acute oral toxicity. 27% of the mixture consists of ingredients of unknown acute dermal toxicity.
