NR-26 was originally published in 1978, based on articles 166 and 167 of the Consolidation of Labor Laws (CLT). Classified as a special regulation, NR-26 focuses on the use of colors in the workplace for safety equipment identification, area demarcation, and warning about risks. The original text also covered labeling of hazardous products.
The 2011 revision introduced significant changes, maintaining the use of colors for safety purposes but with less detailed specifications. It also mandated compliance with official technical standards and required the classification of chemicals according to the Globally Harmonized System (GHS), along with providing Safety Data Sheets for hazardous chemicals.
In 2015, specific adjustments are made, exempting sanitizing products notified or registered with the National Health Surveillance Agency (ANVISA) from labeling obligations, following ANVISA’s rules.
