Dilution Stations: Correct Strength Without Guesswork

Know the hazard

Team: Commercial Cleaners. Topic: Chemical Safety.

A dilution station can make correct mixing easier, but a dispenser is only as reliable as its setup. A mismatched concentrate, loose pickup tube, wrong metering tip, or unlabeled bottle can send the wrong strength to the cleaning cart. More concentrate can increase exposure, damage finishes, and leave residues without improving the intended result.

Use the controls

Match the product, approved dispenser connection, and receiving bottle before filling. Use the PPE and ventilation specified for concentrate handling. Inspect hoses and connections visually without opening pressurized components. Follow the manufacturer procedure for checking output; never taste a solution or use skin irritation as a strength test. Report a change in color, foaming, consumption, or performance instead of adjusting an unfamiliar dispenser.

Work within the safe plan

Fill only approved containers, maintain workplace identification, and prevent overflow into electrical equipment or incompatible stored products. If the dispenser fails, use an approved backup method with measured amounts and written directions, or postpone the task. A supervisor should control who services metering components. Today our crew will identify what a normal fill looks like and who receives a fault report, so workers do not compensate for a mechanical problem by pouring extra concentrate into every bottle.

Discuss with the crew

A new concentrate fits the shelf but requires a different dispensing connection.

Question: Does shelf location confirm compatibility?
Answer guidance: No; match the approved product and dispenser configuration.

Question: What is the backup when output seems wrong?
Answer guidance: Stop dispensing and use only a supervisor-approved measured method.

Prepare, act, and follow up

Leader preparation: Bring the dilution chart and a disconnected example bottle.

Put it into practice: Compare one station, bottle, and chart as a group.

Supervisor follow-up: Repair and verify faulty dispensers before returning them to use.
