| introduction | n-decanethiol is a colorless liquid with a special smell, which decomposes when burned. Generates toxic gases containing hydrogen sulfide and sulfur oxides. It reacts sharply with the oxidant. There is a danger of fire. Reacts with strong acids, strong bases and strong reducing agents. Erosion of metal and rubber. |
| store | refractory equipment (condition). Store separately from strong alkali, strong acid and oxidant. |
| leak disposal | personal protection: organic gas and vapor filter respirators adapted to the concentration of the substance in the air. Collect leakage and spilled liquid in sealable containers as much as possible. Absorb the night with sand or inert absorbent. They are then stored and disposed of in accordance with local regulations. Do not let the chemical enter the environment. |
