Respirator basics

A 3M 6000 series half-face respirator with P100/OV (organic vapor) cartridges covers contact cement fumes, spray paint, resin, and heated foam. Cost: $25 to $35 for the mask, $12 to $18 for replacement cartridges. Replace cartridges when you start smelling through them.

• N95 masks are NOT enough for chemical fumes. Only use them for dust (sanding, Dremel).
• P100/OV cartridges handle organic vapors from cement, spray paint, and resin.
• Fit the mask tight. If air leaks around the edges, size down or try a different model.
• Store cartridges in a sealed bag between uses to extend their life.

Ventilation is not optional

Work near an open window with a box fan pointing out. Contact cement, spray paint, and resin all produce fumes that cause headaches, nausea, and long-term damage in enclosed spaces. If you can smell it through your respirator, your ventilation is not enough.

Common injuries and how to avoid them

Craft knife slips cause the most cosplay injuries. Always cut away from your body, use a sharp blade (dull blades slip), and keep your off-hand behind the cut line. Hot glue burns are second. Let the glue cool for 2 to 3 seconds before pressing pieces together.
