Which organization develops guidelines and standards and has its own laser classifications?

• A. American National Standards Institute (ANSI)
• B. Food and Drug Administration (FDA)
• C. Occupational Safety and Health Administration (OSHA)
• D. Centers for Disease Control and Prevention (CDC)

Answer: (A)

The organization that develops guidelines and standards and has its own laser classifications is ANSI, the American National Standards Institute. ANSI coordinates national standards across industries and publishes the laser safety standards in the ANSI Z136 series. These standards define the laser hazard classes—ranging from Class 1 through Class 4 (with subcategories like Class 1M, 2M, and 3R)—and specify what protective measures and labeling are required for each class. This is why ANSI is the go-to reference for both guidelines and the laser classification system used to assess risk and guide safe operation. In contrast, the FDA focuses on regulatory status of devices, OSHA handles workplace safety rules, and CDC deals with public health; none of these institutes establishes the laser hazard classifications used in safety labeling.
