Noam Carmeli, the Central Arava Regional Council's security officer, arrived at the scene of the blast and said that the explosion occurred on a drilling facility. He reported that at least three ambulances were treating the wounded.
MDA Director-General Eli Bin expressed sorrow over the event's tragic outcomes. "This event must be examined and studied and lessons must be drawn," he said.
The Health Ministry said, "Hydrochloric acid is dangerous to anyone who comes in contact with it and leaves a burn."
Last year, a major gas leak occurred on the Eilat-Ashkelon pipeline following renovation work near the Zin nature reserve.
Raviv Shapira, southern director at the Nature and Parks Authority, estimated at the time that the leak caused serious ecological damage to the nature reserve and the wadi.
