Hazard Statements
- H302: Harmful if swallowed.
- H312: Harmful if absorbed through skin.
- H315: Irritating to skin.
- H332: Harmful if inhaled.
- H350: This product is or contains a component that is classified (ACGIH, IARC, NTP, OSHA) as a possible cancer hazard.
- H351: The consistent finding in animal studies with PCBs is that they produce liver injury and are suspected of causing cancer following prolonged and repeated exposure by any route, if the exposure is of sufficient degree and duration. Liver injury is produced first, and by exposures that are less than those reported to cause cancer in rodents. Therefore, exposure by all routes should be kept sufficiently low to prevent liver injury.
- H360: California Proposition 65 Warning: This product contains a component (or components) that may cause cancer and genetic effects in a concentration greater than or equal to 0.1%.
- H371: May cause liver damage.
- H413: May cause long-term adverse effects in the aquatic environment.
Precautionary Statements
- P262: Do not get in eyes, on skin or clothing.
- P202: This product should only by used by persons trained in the safe handling of hazardous chemicals.
- P233: Store in a tightly closed container.
- P260: Do not breathe dust.
- 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.
- P340: Inhalation: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention.
- 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.

Emergency First Aid Measures
Critical first aid procedures for chemical exposure incidents and medical emergencies
🫁 Inhalation Exposure
Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention. (P340)
🖐️ Skin Contact
Immediately wash skin with soap and plenty of water. Remove contaminated clothing. Get medical attention if symptoms occur. Wash clothing before reuse. (P360)
👁️ 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. (P338)
🍽️ Ingestion/Swallowing
Do NOT induce vomiting or give any oily laxatives.
Medical Treatment
A petroleum-based ophthalmic ointment may be applied to the eye to relieve the irritating effects of PCBs. If large amounts are ingested, gastric lavage is suggested.
