I researched it for work years ago, we were using it as a cleaning agent and they had very strict chemical substance controls. That being said, I wouldn’t inhale it, i.e., maintain good ventilation, and I would wear gloves when using. Aside from people potentially passing out from inhalation, I could only find one instance of contact exposure, but the patient was soaking rags and applying it to their arms daily. Ignoring flammability concerns, I think the resin poses a greater health risk than the isopropyl.
