Is UL required by OSHA?

The Occupational Safety and Health Administration (OSHA) is a regulatory body that establishes and enforces workplace safety standards in the United States. One common question many businesses have is whether Underwriters Laboratories (UL) certification is required by OSHA for their products or equipment.

Understanding OSHA Requirements

OSHA regulations are designed to ensure safe working conditions for employees and prevent workplace accidents. However, OSHA does not directly require UL certification for products or equipment used in workplaces. Instead, OSHA focuses on performance-based standards and requires employers to provide a safe environment for their workers.

While UL is not mandatory by OSHA, it is essential to understand that having UL certification can be beneficial for both manufacturers and employers. UL is an independent organization that conducts rigorous testing and evaluation of products for safety and compliance with industry standards.

The Benefits of UL Certification

Although not mandated by OSHA, UL certification offers several advantages. First and foremost, UL-listed products carry credibility and trust. UL's reputation as one of the leading product safety organizations gives manufacturers an edge in the market by demonstrating their commitment to safety and quality.

Additionally, using UL-certified products can help employers meet their general duty obligations under OSHA. By choosing products with UL certification, employers can be confident that they are providing equipment that meets high safety standards, reducing the risk of workplace accidents.

Furthermore, in specific industries such as construction and electrical work, UL certification may be necessary to comply with other regulatory bodies or codes. Many local authorities and project specifications require UL-listed products to ensure safety and compliance with building regulations.


While UL certification is not explicitly required by OSHA, it is highly recommended due to the benefits it offers. UL certification ensures that products meet rigorous safety standards and helps businesses gain a competitive edge in the market. Additionally, using UL-certified products can assist employers in meeting their obligations for providing a safe workplace. Therefore, companies should consider obtaining UL certification to ensure the safety, quality, and compliance of their products and equipment.
