PURPOSE: To analyze the legislation regarding occupational risks, highlighting those related to teacher's health and voice. METHODS: A bibliographic search of qualitative nature regarding the public policies about Health and Security at Work was carried out. The Regulatory Standards were read and their contents analyzed and organized into categories, detaching those from the scholar environment. RESULTS: The 33 regulatory standards focus the risk factors, tolerance levels, and control for health and security at work. The harmful environmental agents are multiple and their specificities, such as concentration and frequency, determine the level of tolerance to exposition. At school, the environmental risks like noise, dust, temperature and inadequate lighting, among others, are present, however in a mild degree. The acoustic, lighting and exhaust ventilation treatments are indicated for the control of such risks. The documents show situations of worsening of the workers' health in much higher degrees of risk than those from teaching activities. There is no explicitation of factors inherent to the work organization, and the care with the voice is limited to the profession of telesales workers, which can serve as a reference to the teacher's work. CONCLUSION: Labor legislation is ample to cover the diversity of work conditions and to ensure the workers' health. Teaching presents milder occupational risks to health than other professions; nevertheless, the organizational factors of work, as well as voice disorders, very frequent in this activity, demand greater attention from Brazilian legislation.
