A Tesla spokesperson didn’t immediately respond to a request for comment on the Cal/OSHA investigation. We’ll update the story if we hear back.

Update 7:20 PM EDT: A Tesla spokesperson responded with the following statement:

The injury rate at our Fremont factory is half what it was in the final years of the UAW plant operated by GM/Toyota immediately before us, and we care deeply about the safety and well-being of our people and strive to do better every day. Cal-OSHA is required to investigate any claims that are made, regardless of whether they have merit or are baseless (as we believe these are), and we always provide our full cooperation. Last year, a Cal-OSHA investigation into our injury reporting and record-keeping was closed without any violations found and without any further action taken. In fact, unlike other automakers who in the past have been cited by OSHA for record-keeping violations, we have never in the entire history of our company received a violation for inaccurate or incomplete injury record-keeping.
