Hazard statements
H300 - Fatal if swallowed. (Acute toxicity, oral, category 1) H310 - Fatal in contact with skin. (dermal, category 1) H315 - Irritating to skin. (Skin corrosion/irritation, category 2) H317 - May cause allergic skin reaction. (Sensitization, skin, category 1) H318 - Causes serious eye damage. (Eye damage/irritation, category 1) H330 - Fatal if inhaled. (Acute toxicity, inhalation, category 1) H340 - May cause heritable genetic damage. (Germ cell mutagenicity, category 1) H341 - This compound is classified as a possible mutagen. There is no acceptible exposure limit for a mutagen. (Germ cell mutagenicity, category 1) H410 - Very toxic to aquatic life with long lasting effects Precautionary Codes: P202 - This product should only by used by persons trained in the safe handling of hazardous chemicals. P233 - Store in a tightly closed container. (P404) P235 - Store in a cool dry place. P262 - Do not get in eyes, on skin or clothing. P264 - Wash thoroughly after handling. Do not take internally. Eye wash and safety equipment should be readily available. P280 - Protective gloves must be worn to prevent skin contact. P284 - Respiratory Protection: If workplace exposure limit(s) of product or any component is exceeded (see TLV/PEL), or a risk assessment shows air-purifying respirators are appropriate, use of a NIOSH/MSHA approved air supplied respirator is advised. Use a full-face respirator with multi-purpose combination (US) or type ABEK (EN14387) respirator cartridges in absence of proper environmental control. Always use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU). Engineering and/or administrative controls should be implemented to reduce exposure. P338 - Eye contact: Immediately flush with plenty of water. After initial flushing, remove any contact lenses and continue flushing for at least 15 minutes. Assure adequate flushing by separating the eyelids with fingers. P360 - Skin contact: Immediately wash skin with soap and plenty of water. Remove contaminated clothing. Get medical attention if symptoms occur. Wash clothing before reuse.
2.3 Other hazards
2.2.1 - Symptom of Exposure Health/Environment May cause allergic skin reaction. (Sensitization, skin, category 1) May cause cyanosis (blue-gray coloring of skin and lips caused by lack of oxygen). May cause heritable genetic damage. (Germ cell mutagenicity, category 1) Very toxic to aquatic life with long lasting effects May cause headache, dizziness, nausea, vomiting, general malaise, muscle twitching, and convulsions. This compound is classified as a possible mutagen. There is no acceptible exposure limit for a mutagen. (Germ cell mutagenicity, category 1)
Potential health effects
