According to the NIOSH Handbook, which of the following statements about acetic acid is correct?

• A. It is compatible with strong oxidizers
• B. It has a NIOSH REL of 10 ppm
• C. It can affect the respiratory system
• D. It is a non-hazardous chemical

Answer: (C)

The statement that acetic acid can affect the respiratory system is correct. Acetic acid is classified as an irritant, and exposure to its vapors can lead to respiratory irritation, which may manifest as coughing, difficulty breathing, or other respiratory problems. This means that workers handling acetic acid must be aware of the potential for inhalation exposure and implement appropriate safety measures to protect their respiratory health. In contrast, acetic acid is not compatible with strong oxidizers, as this could lead to hazardous reactions. While it does have a recommended exposure limit (REL), the specific value is essential for ensuring safety, along with understanding that the actual REL is not 10 ppm. Additionally, describing acetic acid as a non-hazardous chemical is misleading; it is, in fact, classified as a hazardous substance due to its corrosive properties and the potential health effects associated with exposure.
