O erro que invalida avaliações de óleo mineral na Higiene Ocupacional - HR#278

Many professionals use NIOSH 5026 in machining fluids without realizing that the result may be technically biased. 🔥Secure your ticket for the third edition of the Hands-on Chemical Risks Challenge! 🔗 https://r.hofacil.com.br/youtube-ingr... The problem isn't the equipment. Nor the laboratory. It's the technical decision of those who choose the method without understanding its limitations. Machining fluid is not pure mineral oil. And ignoring the additives present in the mixture completely compromises the interpretation of occupational exposure. In this video, you will understand: • The difference between NIOSH 5026 and NIOSH 5524 • Why calibration directly interferes with the result • How additives affect infrared readings • And the common error that invalidates many occupational risk assessments --- Hi, are you breathing well over there?
