What must be visible and legible during business hours?

The requirement for a visible and legible telephone number during business hours is essential because it ensures that customers can easily reach out for assistance, inquiries, or emergency situations. A visible telephone number enhances communication, fosters trust, and reflects professionalism, as it shows a business is accessible and responsive to its clientele. Additionally, having a clear line of communication supports customer service and safety protocols, which are particularly important in the LP-gas industry due to its regulatory and safety implications.

While training certifications, license documents, and company policies are also important in the context of compliance and operational integrity, they do not carry the same immediate urgency for customer access during business hours as a telephone number does. Customers need to have a direct means to communicate effectively with the business at any time, especially in situations involving gas safety or service inquiries.
