Demonstrate procedures to measure and mix chemicals, including volatile chemicals (e.g., furniture and floor strippers, drain cleaners).
DefinitionDemonstration should include
- selecting PPE, materials, and tools
- identifying various volumes of measuring cups
- mixing chemicals according to the manufacturer's instructions or other specified ratios.
- Why must you be familiar with various volumes of measuring cups when measuring chemicals?
- Where would instructions be found for mixing a given chemical to the manufacturer's specifications?
- Where can information on exposure precautions and limits be found?
- Why must adequate ventilation be used when mixing volatile chemicals?
- What procedures should be followed for volatile chemical spills?
