OSHA Clarifies Recordkeeping Expectations Around Lithium-Ion Battery Hazards

The Occupational Safety and Health Administration has issued a new Letter of Interpretation reinforcing employer responsibilities tied to workplace risks associated with lithium-ion batteries. As battery use expands across manufacturing, logistics, energy storage, and equipment operations, OSHA is emphasizing the importance of recognizing and documenting safety and health hazards tied to battery production, use, emergency response, disposal, and recycling.

Lithium-ion batteries present unique exposure risks that extend beyond routine electrical safety. OSHA notes that potential hazards include fires, explosions, and worker exposure to hazardous chemicals released during battery failure or improper handling. These risks are increasingly relevant in environments where batteries are stored in bulk, integrated into equipment, or processed at end of life.

OSHA highlights practical prevention measures employers can implement to reduce risk:

• Applying hazard controls during battery design and production processes
• Ensuring proper ventilation in battery handling and storage areas
• Storing batteries in cool, dry, controlled environments
• Monitoring storage spaces for flammable or toxic gas buildup
• Using designated recycling facilities for disposal
• Installing safety showers and eyewash stations where battery materials are handled

For employers, this guidance reinforces that lithium-ion battery safety is not only an engineering issue but also a recordkeeping and compliance priority. Injury and exposure documentation, hazard assessment, and prevention planning must align with evolving federal expectations.

WorkCare encourages organizations to proactively review battery safety protocols, incident reporting workflows, and worker protection measures. Early hazard recognition and structured occupational health oversight help reduce escalation risk while strengthening compliance confidence.
