"Avoid touching it or getting it in your eyes", the Hawaii County Civil Defense Agency said.
Lava gushed across and then along a roadway that leads from the commercial centre of Pahoa toward smaller towns and rural farmlands to the east.
The occurrence of new lava vents, or fissures, now numbering about two dozen, have been accompanied by flurries of earthquakes and intermittent eruptions from the summit crater, including a magnitude 5.3 tremor measured on Wednesday. The lava that is now coming to the surface is the hottest and most fluid to date.
"Rather than shock and surprise it was more of a resolve that, OK, it's come to us now", Steven Neill, a Kapoho evacuee, told CNN affiliate KGMB/KHNL on Wednesday.
Some feared a breach if lava penetrated the well shafts that tap steam and hot water to make electricity. "And if you add sulfuric acid (in vog, for example) to sugar, you get a pretty spectacular reaction".
Officials said the lava destroyed the electric utility's equipment on the highway which led to power losses at the Vacationland and Kapoho Beach lots.
Civil defense officials have previously said about 2,000 residents in and around Leilani Estates were displaced at the outset of the current eruption, which began on 3 May.

As of 6:15 a.m., the lava flow was about 2 miles west of the Four Corners intersection, said USGS volcanologist Jessica Ball. As lava rushed past the property, a USGS crew that was flying the drone used the aircraft to lead rescue teams to the stranded person.
A man was arrested in Leilani Estates after police say he fired a gun and assaulted another man after demanding that the man and his friends leave the area Tuesday.
The Hawaii community hardest hit by the Kilauea Volcano was ordered sealed off under a strict new mandatory evacuation on Thursday as the eruption marked its fourth week with no end in sight. They hope the roadway will provide an alternative escape route if lava cuts off more roads to the north. The strands can cause irritation and respiratory problems when it comes in contact with people.

Besides spouting fountains of lava around the clock, the fissures have released high levels of toxic sulfur dioxide gas on a near constant basis, posing an ongoing health hazard.
