I want to know the answer to the following question:
What does REL stand for?
All the background I'm provided with is that "The National Institute for Occupational Safety and Health (NIOSH) has set a recommended exposure limit (REL) of 0.2 mg/m3 over an 8-hour workday and a short-term limit of 0.6 mg/m3.". Is that enough to answer the question?
Answer: yes
