Análise do estresse térmico pelas normas NR 15 (2011) e ISO 7243 (1989) em uma central de esterilização de instrumentos odontológicos

Abstract

This study aimed to analyze the thermal situation of a dental instruments sterilization central in Ponta Grossa by applying the WBGT index. This index is standardized nationally by NR 15 (2011) and internationally by ISO 7243 (1989), which have the same method of calculation, but different modes of interpretation. For the interpretation of NR 15 (2011), the environment was considered inadequate as the value found for IBUTG was higher than the tolerance level, and modifications are required. On the other hand, according to the international standard ISO 7243 (1989), the environment was considered adequate, but despite the average WBGT is below the tolerance limit values, the value was very close to the limit. It is suggested that the work environment is changed so as to isolate the autoclaves of benches, allowing enclose the heat generated by the operation of the equipment.
