Recognizing and responding to heat illness in the workplace is crucial for protecting team member health and ensuring a safe working environment. Heat-related illnesses escalate rapidly and become life-threatening if not addressed promptly. By staying vigilant for symptoms and taking early action, we can help foster a culture of safety and care.
