What should happen in a new chemical program's first 90 days?

This plan fits cooling water, boiler water, metalworking fluid and similar plant chemical programs where a supplier and the plant share the work. It does not cover permit startup periods for wastewater discharges, which the permit sets, or product trials run before a supplier is chosen.

What do you need before a new chemical program starts?

Before a new chemical program starts, you need a written scope, the safety data sheet (SDS) for every new product, a test method for each controlled parameter, and named owners on the plant and supplier sides. Without these, the first 90 days go into arguing about what was agreed.

The scope lists each system covered, such as a cooling tower, a boiler, a closed loop or a central coolant system, with its volume, materials and operating conditions (illustrative examples). The SDS set should reach the plant before the first delivery, for operator training and the plant's chemical records. Write down the test method per parameter with the kit or instrument used, since a reading taken by a different method is not comparable with the baseline. ISO 9001:2026 includes clause 7.1.5, Monitoring and measuring resources (ISO, 2026), which is where a certified plant keeps its rules for test equipment.

Then name the owners: who on the plant side takes readings, who approves changes to the program, and who on the supplier side reviews the results and answers questions.

Which baseline readings should you take before a new chemical program starts?

Take baseline readings of every parameter the new chemical program will control, plus the equipment condition it is meant to protect, before the first dose and under recorded operating conditions. A baseline taken after the first dose cannot show what the new program changed.

For a cooling water program, the baseline might include makeup and system water chemistry, corrosion coupon data, deposit and fouling observations, and microbiological counts; for a metalworking fluid, it might include concentration, pH, tramp oil, bacterial counts, tool life and machine cleanliness (illustrative examples). Record the operating conditions with each reading, such as load, temperature, makeup rate and production volume, because a change in conditions can look like a program effect.

Take more than one reading where values swing. The HSE's COSHH guidance on control measures says checks may be needed quite frequently at first, and that after this baseline period the records should show the pattern of deterioration or sustained effectiveness (HSE, accessed 2026). Store the baseline with the date, method, unit and who measured, in a place both the plant and the supplier can open.

Running the first 90 days of a new chemical program, step by step

Running the first 90 days of a new chemical program takes five steps, each ending in a record; the day markers are illustrative.

1. Days 1 to 10: take the baseline readings under recorded conditions, before the first dose. If the new product replaces another, empty or flush tanks and feed lines first and check both SDSs (Section 10, Stability and reactivity) for incompatibility (OSHA, 2026).

2. Days 1 to 10: agree target ranges in writing, with minimum, maximum, unit, method and who agreed each one.

3. Before first handling: train the operators who will handle the product or take readings on the SDS, the test method and the action outside the range.

4. Days 10 to 80: take the plant-owned readings at the agreed frequency and send them to the supplier on a fixed day.

5. By day 90: hold the first review, compare results with the baseline and the target ranges, and decide what changes.

Readings are usually taken more often in the first weeks and reduced once results are stable, in line with the HSE's advice that check frequency can be adjusted after an initial baseline period (HSE, accessed 2026). In a building water system with a Legionella water management program, the CDC guide lists changes in treatment products as a reason to review and revise that program (CDC, 2025), so the new chemical program should also start that review.

How do you agree target ranges for a new chemical program?

Agree target ranges for a new chemical program by writing, for each controlled parameter, a minimum, a maximum, the unit, the test method and the action when a reading falls outside, and by having both the plant and the supplier sign off. The CDC water management guide says control limits for a chemical or physical parameter should include a minimum and a maximum value (CDC, 2025).

Start from the supplier's product documents and the plant's equipment limits, then check the proposed ranges against the baseline. A range the baseline already meets proves nothing about the program, and a range the plant cannot measure with its own kit will not be followed. Record why each range was chosen, such as an equipment maker's limit, a past failure or a discharge permit condition (illustrative examples), so a future manager can keep the range instead of reopening it.

Mark the ranges that are provisional until the first review, so both sides know which numbers may change at day 90 and which are fixed by safety, equipment or permit limits.

What training do plant operators need in a new chemical program?

Plant operators in a new chemical program need training on the hazards of each new product from its safety data sheet (SDS), on the test methods they will run, and on the action when a reading falls outside its range, before they first handle the product. In the US, the Hazard Communication Standard requires employers to provide effective information and training on hazardous chemicals at the time of initial assignment, and whenever a new chemical hazard the employees have not previously been trained about is introduced into their work area (OSHA, 2026).

In Great Britain, the HSE's COSHH guidance tells employers to inform and train all employees on the hazards and risks from substances with which they work and on the use of control measures (HSE, accessed 2026). Check the equivalent rule in the plant's own jurisdiction.

Keep the training practical: where the SDS is kept, which personal protective equipment the SDS names, how to take and record each reading, and whom to call. Record who was trained and when; late joiners and shift crews who missed the session need the same training before handling the product.

Which readings should the plant take itself in a new chemical program?

The plant should take the frequent, simple readings that show whether the new chemical program is in range from day to day, such as concentration, pH, conductivity or residual, while the supplier takes the periodic tests that need a lab or specialist equipment. Each plant-owned reading needs a method, a frequency, a person and a place to record it.

Write the split down, because each side tends to assume the other is measuring. A short list per system works: parameter, method, frequency, who takes it and where it is recorded (illustrative layout). Keep the plant's list to readings someone uses for a decision. The HSE notes that routinely measuring and recording no change over long periods is among the things most likely to make people stop taking checks seriously (HSE, accessed 2026).

Agree how the readings reach the supplier, through a shared log, a form or a regular file sent on a fixed day. Retyping values from photos and emails adds errors, a problem covered in collecting site readings from customers without retyping.

When should the first review of a new chemical program happen?

The first review of a new chemical program should happen within the first 90 days, once enough readings exist to compare with the baseline, and sooner if readings stay outside the target ranges. The date is an agreement between the plant and the supplier rather than a general rule. In a different field, a California water board allowed a startup period of up to 90 days for biological treatment units to meet effluent limits (North Coast Regional Water Quality Control Board, 2020).

The review compares results with the baseline, confirms or changes the provisional ranges, and resets the reading frequency. The check table below tests each part of the first 90 days.

The baseline row decides the most: if it fails, the review cannot show what the program changed. After the first review, the CDC guide's rule of reviewing a water management program at least once per year (CDC, 2025) is a reasonable floor for building water systems.

When should you call a specialist about a new chemical program?

Call a specialist about a new chemical program when readings stay outside target ranges after feed and dosing have been checked, when equipment condition gets worse than the baseline, or when the program adds a hazardous feed such as an acid, oxidizer or biocide.

Persistent excursions after the dose is verified point to a demand or chemistry the program was not designed for, and the CDC guide lists control measures persistently outside control limits as a reason to review a water management program (CDC, 2025). Corrosion, deposit or microbiological results worse than the baseline need someone who can read coupons, deposit analyses or culture results. A new acid, oxidizer or biocide feed should be checked against each product's SDS and label before it starts, with operators trained under the Hazard Communication Standard, 29 CFR 1910.1200(h) (OSHA, 2026), or the COSHH duties in Great Britain (HSE, accessed 2026).

The startup record is easier to review when baseline, readings and documents sit in one place for both sides. In Lubinpla, a supplier records the operating conditions and baseline values in a project, receives the plant's readings through site data requests that become project records once the supplier's team approves them, and shares startup documents with the plant contact through Field Care.
