| Storage and Leakage Handling |
[Leakage disposal]: evacuate people living in polluted areas to a safe area, prohibit unrelated persons from entering contaminated areas,
Recommended emergency personnel wearing self-contained breathing apparatus, wear chemical protective clothing.
Do not directly contact the spill, plugging to ensure safety.
Mixed with sand or other non-flammable absorbent absorption, and then transported to the collection and disposal of waste disposal sites.
Can also be washed with plenty of water, diluted by washing water into the wastewater system.
Such as large leaks, the use of dike embankment, and then collect, transfer, recycling or harmless disposal.
[Other]: After work, take a shower. Pay attention to personal hygiene.
