Subject: [DCHAS-L] On laboratory fume hoods and chemicals cabinets
I am seeking guidance on locating up-to-date information regarding the following:
- Guidelines for laboratory fume hoods designed exclusively for handling chemical agents. How can I determine if an older laboratory fume hood complies with current standards?
- Requirements for chemical cabinets used to store flammable chemicals. My question about the fume hood also applies here.
While we plan to conduct a thorough risk assessment based on the range of chemicals to be used, I would appreciate clear guidance on where to find information that can help us assess the suitability of existing infrastructure post-assessment.
