According to OSHA standards, which of the following is NOT a requirement for laboratory coats?

The correct choice highlights a detail about laboratory coat requirements according to OSHA standards. Laboratory coats are indeed expected to be made of cloth fabric that can be readily laundered, as this allows for proper cleaning and maintenance to reduce contamination risks. However, it's important to note that while many laboratory coats are designed to be laundered, the specific requirement does not stipulate that they must be made of this material or that such a fabric is an absolute necessity — other materials may also be compliant as long as they provide adequate protection.

In contrast, items that are required by OSHA standards — like water resistance, long sleeves for better protection, and the expectation that coats be worn buttoned — are established safety protocols meant to protect workers from hazardous materials and potential biological contaminants in the laboratory environment. Thus, the focus on launderability, while important, does not establish a standalone requirement that excludes other acceptable materials from being used for lab coats, making the correct answer relevant in understanding the nuances of the OSHA standards in laboratory settings.
