Lab coats used in histology must meet certain safety standards to ensure they provide adequate protection. These standards are set by organizations such as the Occupational Safety and Health Administration (OSHA) and the American National Standards Institute (ANSI). Lab coats should be flame-resistant, chemical-resistant, and provide sufficient coverage to protect the wearer from potential hazards. It is important to choose lab coats that meet these standards to ensure a high level of safety in the lab.
