Occupational exposure to chemical agents is the contact between the chemical agent and the worker's body, which may occur through the respiratory tract (inhalation), dermal or ocular (contact and/or absorption). Such exposure has the potential to cause local and/or systemic damage to health. The risk of damage to health is reduced by adopting several preventive measures, among which the following stand out: 1. Proper use of Personal and Collective Protective Equipment (PPE/EPC): According to NR-6, PPE is defined as a product or device for the exclusive use of the worker, designed to protect him/her from occupational risks present in the work environment. It is important to note that only equipment that has a valid Certificate of Approval (CA) issued by the Ministry of Labor and Employment (MTE) is authorized for sale or legal use. 2. Training and awareness: Continuous training of workers, focusing on the correct use of PPE and CPE, as well as the identification and management of risks related to the handling of chemical and biological agents, is essential to ensure safety in the workplace and prevent accidents. These measures, when correctly implemented, contribute significantly to the reduction of chemical and biological risks and ensure the protection of worker health.
