What action should a worker take immediately if hot-melt rubberized asphalt or molten thermoplastic contacts their skin?

1. Cool the affected skin area immediately with cold water; do NOT peel material off.
2. Scrub the hot material aggressively off the skin using solvent thinners right away.
3. Cover the molten material with hot sand and wrap tightly with dry gauze.
4. Apply grease or petroleum jelly over the molten material to loosen it.
