Which two US government agencies are primarily involved in laser regulation?

The correct answer identifies OSHA (Occupational Safety and Health Administration) and FDA (Food and Drug Administration) as the two primary agencies involved in laser regulation in the United States.

OSHA is responsible for ensuring safe and healthful working conditions by setting and enforcing standards, including those related to the use of lasers in occupational settings. They establish guidelines to protect workers from hazards posed by laser use, which can include burns, damage to eyes, and other safety concerns.

The FDA plays a significant role in regulating laser products, especially those that are intended for consumer use, such as laser devices used in medical applications and cosmetic procedures. Their focus is on ensuring that these devices are safe and effective for public use, which includes evaluating the potential health risks associated with different types of lasers.

Both agencies work together, with OSHA concentrating on workplace safety and the FDA overseeing the safety and efficacy of laser devices in the consumer market, making them essential partners in laser regulation. The other options either include agencies that may not primarily focus on laser safety or represent agencies that have different regulatory focuses.
