• safety goggles

• protective face mask

• neoprene gloves

• boots or closed shoes

Preparing the Alkaline Cleaning Solution

Always add caustic soda to water. Never pour water onto caustic soda. Mixing it with water

creates heat that could ignite other materials. For information see DOC-08380, “Working with

Alkaline Cleaning Solution”.

Waste Disposal

Fully cured models present no special safety or health-related issues. However, check if local

regulations regard cured and partially cured resins as hazardous industrial waste, and comply

with all applicable regulations governing their disposal.

Dispose of the alkaline cleaning solution according to local regulations.

Consult your company safety officer before handling the solution to check if you need

to take additional protective measures.
