Isolate leakage contaminated areas and restrict access. Cut off the source of fire. Emergency responders are advised to wear self-contained breathing apparatus and firefighting protective clothing.
Small leaks: Collect in a dry, clean, covered container using a non-sparking tool. Transfer recycling.
Lots of leakage: Cover with plastic sheeting, canvas to reduce scattering. Use a non-spark tool to collect, transfer, and recycle.
