The Pentagon has sent inspectors to Afghanistan to examine electrical wiring on U.S. bases, a step called for after several incidents of troops and civilians being electrocuted on U.S. bases in Iraq.

According to several media reports Thursday and Friday, the Defense Department’s office of the inspector general sent the teams in April, though their findings are still being compiled and have not yet been scheduled for release.

Several servicemembers have been killed in Iraq by electrocution, whether in faulty showers or other electrical incidents. Investigations there have shown that around a third of the U.S. bases in Iraq have “major” electrical problems, according to The Associated Press.

Those concerns have led officials to examine the bases in Afghanistan, which, in many cases, have been built or wired by the same contractors hired for Iraq work.

A Senate committee has also scheduled a Capitol Hill hearing for next week to examine the electrical work on the U.S. bases and the Pentagon’s response, the AP said.
