Chemistry Fundamentals

1. Label all chemicals and concentration units clearly.
2. Set PPE and ventilation rules before mixing.
3. Use clean measuring tools and controlled records.
4. Never scale formulas until small-batch tests pass.

• Add acid to water, never reverse.
• Never mix unknown chemicals.
• Use dedicated containers for each process.
• Keep neutralization and rinse station ready.

Most chemistry injuries come from rushed handling and poor labeling.

• Mistake: guessing concentrations. Fix: measured ratios only.
• Mistake: poor recordkeeping. Fix: lot, date, operator log.
• Mistake: no compatibility checks. Fix: compatibility table at station.
• Mistake: storage near heat/light. Fix: cool dark controlled shelf.

Drill 1: Label Failure Event

1. Inject unlabeled bottle into workflow.
2. Execute quarantine protocol.
3. Run corrective log and cleanup.
4. Goal: zero unknowns re-enter process.

Drill 2: pH Correction Run

1. Start with off-spec solution.
2. Bring into target pH safely.
3. Hold and verify stability.
4. Goal: correct without overshoot.
