Amazon is reportedly installing new air conditioning equipment and fans at its ewr9 warehouse in New Jersey. This comes after reynaldo Mota frias, a worker at the facility, died on July 13th. An investigation by the Occupational Safety and Health Administration is listed as ongoing.

The company has faced criticism about how it handled workloads during the increasingly warm summers. Last year, some of the company’s workers in Kent, Washington said they had to work’power hours’ during a historic heat wave.

Earlier this year, an advocacy group claimed that the company’s workers were twice as likely to be injured than people working similar jobs at other companies. Osha expanded a nationwide investigation into workplace safety at the company.

Amazon did n’t immediately respond to the verge’s request for comment on the air conditioning installation at ewr9. A spokesperson for the company said that it has safety teams that will’take action to address any temperature-related issues’.
