A significant portion of the workforce speaks Spanish, creating a multilingual environment where cross-cultural collaboration is part of day-to-day operations. The plant emphasizes strict adherence to health, safety, and environmental policies, including the consistent use of approved personal protective equipment (PPE), such as respirators when required, and compliance with respirator fit standards.
