A 47-year-old worker died Thursday after sustaining severe burns at the Haifa Bay area factory where he worked.
Police were investigating whether the man, from the Western Galilee Arab town of Mazra’a, was electrocuted.
Emergency services pronounced him dead at the scene.
Yoel Levinger, a paramedic for the Magen David Adom rescue services, said the man had suffered significant burns all over his body.
An eyewitness, who said that the factory dealt with glass, described seeing smoke but no flames.
Earlier in the week, a worker aged around 30 was seriously hurt after falling at a building site in the southern city of Beersheba.
On Monday, a 22-year-old laborer was moderately injured when he was electrocuted at work in Jerusalem.
The rate of worker deaths in Israel is among the highest in the West, and double that of the European Union average, according to the findings of an Economics Ministry and National Insurance Institute report published in May 2016.
