Key Hazards
- Contact with rotating mixer paddles
- Dust exposure from dry plaster or additives
- Splashes to eyes or skin during mixing
- Electric shock from cords, plugs, or wet conditions
- Strains from lifting bags, buckets, or mixing containers
- Slips from spilled plaster, water, or wet floors
2–3 Minute Talk Script
Plaster mixers can make mixing faster, but they combine rotating equipment, dry dust, wet material, electrical hazards, and material handling.
Workers should inspect the mixer before use. Paddles, guards, handles, cords, plugs, switches, buckets, stands, and attachment points should be checked.
Dry plaster can create dust when bags are opened, poured, or dumped into containers. Workers should avoid breathing dust and use respiratory protection when required.
Hands, clothing, hair, and tools should stay away from rotating paddles. The mixer should be stopped and de-energized before reaching into the container or clearing material.
Splashes can occur when water, plaster, or additives are mixed too quickly. Eye protection, gloves, and long sleeves may be needed.
Electrical tools should be protected from wet floors, puddles, damaged cords, and improper extension cords. GFCI protection may be required.
Bags and buckets can be heavy and awkward. Workers should use safe lifting methods or assistance when needed.
Safe plaster mixer use depends on inspection, dust control, splash protection, electrical safety, stable containers, and cleaning spills before they create slip hazards.
Safety Reminders
- Inspect the mixer and paddle before use.
- Control dust when opening and pouring dry plaster.
- Keep hands and clothing away from rotating paddles.
- De-energize before cleaning or adjusting.
- Wear PPE for dust and splash hazards.
- Protect cords and plugs from wet conditions.
- Clean up spills promptly.
