Well, if this is an ionic "liquid," this is erroneous advice:
Eye/face protection Safety glasses with side-shields conforming to EN166 Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).
Should be splash goggle not safety glasses with side sheilds
I would not begin to hazard a guess without reviewing the rest of the SDS, or at the very least, Section 1 and the toxicology section.
This section 8 seems to have been written for industrial quantities and processes, rather a usual thing to do, and perhaps has "benefited" from legal review and editing.

From: ACS Division of Chemical Health and Safety <DCHAS-L**At_Symbol_Here**Princeton.EDU> On Behalf Of Murphy, Dr. Ruth Ann Sent: Friday, September 3, 2021 3:57 PM To: DCHAS-L**At_Symbol_Here**Princeton.EDU Subject: [DCHAS-L] Quick Question
Greetings and Happy Labor Day Weekend,
Should a compound (ionic liquid) with the following SDS statement be safe to use in small amounts, e.g., 5 g, in a fume hood, without a respirator? We would just be making solutions and running them through a viscometer. Students are enthusiastic about this project, but I am cautious. The highlighted info in the SDS statement below about a risk assessment seems a bit cryptic.
SECTION 8: Exposure controls/personal protection 8.1 Control parameters Components with workplace control parameters Contains no substances with occupational exposure limit values. 8.2 Exposure controls Appropriate engineering controls Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the end of workday. Personal protective equipment Eye/face protection Safety glasses with side-shields conforming to EN166 Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU). Skin protection Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique (without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands. Body Protection Impervious clothing, The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace. Respiratory protection Where risk assessment shows air-purifying respirators are appropriate use a full- face respirator with multi-purpose combination (US) or type ABEK (EN 14387) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator. Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU).
Thank you!
