If you have a question about a topic not discussed in this issue, feel free to call DIS at DSN 240-3502. Our safety and occupational health representative told us to wear these gloves, but they only seem suitable for handling doughy resin. When attaching handles to trays and smoothing the area, the gloves are worthless. Although nitrile gloves are less permeable than latex gloves, they should be changed immediately if they come in direct contact with monomer. Unfortunately nitrile gloves are the only cost-effective gloves with the required manual dexterity suitable for working with monomer.
Latex gloves are very permeable to methyl methacrylate and quickly deteriorate when exposed.
You can try to eliminate exposure to monomer when making custom trays by dipping the end of the handle in monomer and using a tool to smooth the area. Another alternative to eliminate the use of liquid monomer is to use light-cured or thermoplastic tray materials.
