Federal regulators are currently launching an investigation into a chemical spill that occurred at General Motors' Ultium Cells LLC battery plant located in Warren, Ohio. The incident has raised concerns about employee safety and operational protocols at the facility. Fortunately, no employees were harmed or exposed due to the spill.

The OSHA was alerted about the chemical spill on Monday. OSHA has initiated an in-depth investigation, aiming to gather comprehensive information about the incident. This includes examining Ultium Cells' response to the spill, evaluating any potential risks that employees may still face, and determining the extent of exposure resulting from the spill. The spill involved a substance called n-Methylpyrrolidone (NMP). This chemical is commonly used in cathode production to develop a polymer that holds active and conductive materials in batteries. The US Environmental Protection Agency (EPA) has classified NMP as posing an "unreasonable risk" to human health, even though no federal permissible exposure limit for the chemical has been established under OSHA regulations.

Greg Less, the technical director at the University of Michigan Battery Lab, emphasized the potential dangers of NMP, describing it as a hazardous substance. He noted that the chemical has numerous safety concerns associated with it.

In response to the incident, Ultium Cells has temporarily suspended mixing operations at the plant. The company engaged a third-party firm to assist with the cleanup and containment of the spill. Operations in the affected area of the plant will remain paused until a thorough inspection is conducted, and the space is deemed safe for use.

Ultium Cells' spokesperson, Katie Burdette, asserted that the occurrence underscores the effectiveness of the company's safety protocols and reporting procedures. Burdette emphasized that the swift and coordinated actions taken by the teams demonstrate the commitment to safety and preparedness.

However, the United Auto Workers (UAW) expressed dissatisfaction with the incident. UAW President Shawn Fain criticized General Motors for prioritizing Ultium Cells' financial performance over the safety of its workforce. He lamented the pattern of health and safety hazards experienced by employees at Ultium and called for the adoption of higher health and safety standards at the company.

Fain pointed out that these accidents are preventable and manageable, highlighting that the company's focus should be on upholding human safety rather than solely concentrating on financial outcomes. This incident, according to Fain, highlights the pressing need for Ultium to uphold the same robust health and safety standards that generations of auto workers have fought for and established at General Motors.
