>>6968053>Can resin be harmful to the environment it's in when it's not dusty? Once cured, synthetic resins are inert.
>Like can particles of it fall off a figure or something?No. Synthetic resins are relatively durable. When they deteriorate, they don't produce fine particulate.
>And do resin particles linger? I'm guessing it would be best not to do it in a basement, but I'm guessing it's also not something you do outside. Yes, synthetic resin particles do linger. Think of dust made out of plastic that's non-biodegradable, and it does pose a serious health hazard where symptoms can manifest immediately or years down the road. Synthetic resin dust can cause eye and respiratory irritation, lung cancer, and pulmonary fibrosis (scarring in the lungs).
>So where should I dust the resin?Do you mean "sand" the resin? If so... Protect exposed skin. Wear eye and hand protection. You absolutely need a respirator (NOT those cheap dust masks!) rated for ultra-fine particulates I.e. Respirators that use P100, HEPA rated, or organic vapour rated filtration. You should wet sand and/or use a sanding booth where the synthetic resin particulates are actually captured in a filter medium. If you don't have a sanding booth, sand in front of the intake side of a large box fan with a HEPA-rated furnace filter attached to the intake side of the fan. Ideally, the fan should be placed in an open window.
Before handling a used air filter for disposable, use a spray bottle and spray it down with water first to prevent any resin dust from accidentally becoming airborne again. Don't forget about your clothing. Dampen contaminated clothing using water and a spray bottle then wash them immediately.
When cleaning up your work space, don't use a vacuum unless it uses HEPA-rated filtration. Some of the finer resin dust particulate will pass right through a regular vacuum filter. Wipe down surfaces with a damp paper towel or disposable shop towel.
