Key Hazards

- Splash hazards during pouring or diluting
- Exposure to fumes in poorly ventilated areas
2–3 Minute Talk Script
Chemical mixing safety is essential in water treatment, manufacturing, facility maintenance, and janitorial work. Improper mixing can cause violent reactions, dangerous fumes, or serious burns. Workers must understand compatibility and follow procedures carefully.
Always check labels and Safety Data Sheets before mixing any chemical. Many products—even common cleaners—should never be mixed. Workers must wear appropriate PPE such as goggles, gloves, and face shields.
Different industries encounter unique mixing hazards. Utility workers may dilute chlorine or add treatment chemicals. Manufacturing workers mix solvents or additives. Maintenance staff often mix cleaning concentrates or floor chemicals.
Mixing should always be done slowly, with good ventilation, and using approved containers. Workers should never guess ratios or improvise mixing methods. Clear communication and proper labeling prevent dangerous mistakes.
Safety Reminders
- Never mix chemicals without verifying compatibility.
- Wear splash-resistant PPE.
- Mix slowly and use proper containers.
- Ensure ventilation is adequate.
