Occupational hygiene and chemical product regulation in Brazil

In the field of occupational hygiene, there is a growing concern that the ability to measure worker exposure with sophisticated instruments has led to a focus on compliance rather than prevention. Experts suggest that treating exposure limits as a finish line—where any value below the threshold is considered acceptable—is a mistake. Instead, the focus should remain on reducing exposure as much as possible or replacing hazardous substances with safer alternatives, even when current levels are technically within legal limits.

Additionally, there is a critical distinction between hazardous and controlled products in industrial management. Hazardous products are classified by their physical risks, such as toxicity, flammability, or corrosivity, primarily affecting transport and handling safety. Controlled products are those subject to oversight by public bodies, such as the Federal Police or the Brazilian Army, due to risks regarding illicit use, public security, or national defense. Because these categories are independent, a substance may fall into one, both, or neither, and misclassification can lead to legal, logistical, and safety errors.
