Two controls do most of the work, and both are commonly done in a way that feels protective and is not.

Nitrile, and the data sheet names it

Section 8 specifies the glove material for that product. Nitrile is the usual answer for epoxy; latex is not a barrier to it and vinyl is poor. Choosing by what is in the drawer is the mistake, and it is invisible because a glove you cannot see through feels like protection.

Change them, do not wash them

Once resin is on the outside of a glove it stays there, and reusing it holds the material against your skin for the next session. Gloves are a consumable in this craft, used in quantity, and treating them as equipment rather than supplies is a false economy with a permanent cost.

Take them off the right way

Peeling a contaminated glove off so that the outside ends up on your hand undoes the entire exercise. It takes ten seconds to learn and most people never do.

Ventilation means air leaving the room

A fan that stirs the air moves vapor around; it does not remove it. What is wanted is air drawn across the work and out of the building, with replacement air coming in. A spare bedroom with the door closed is the opposite arrangement and it is where a lot of this craft happens.

Respirators, if the sheet calls for one

A dust mask is not a respirator and does nothing about vapor. If section 8 specifies a cartridge type, that is the specification, and a cartridge has a service life that runs whether or not you are wearing it.

Protect the surface too

A covered bench means a spill is thrown away rather than cleaned with solvent, which removes an exposure rather than managing one. It is the cheapest control on this page.
