How to Specify Operator Training in an RECD Purchase Order

Look at almost any RECD quotation and you will find the same line near the bottom: “Training to operators: included.” It costs nothing to write, and it is often worth about the same.

When training is left as a one-line promise, it usually becomes a fifteen-minute walk-around on commissioning day, delivered to whoever happens to be in the plant room, with a manual handed over at the end. Six months later, the night-shift operator does not know what a rising backpressure reading means, the maintenance team has never opened the inspection port, and nobody can find the manual.

The fix is not complicated. Treat training as a deliverable with a defined audience, content, duration, format, evidence and acceptance test, and write all of that into the purchase order. This guide explains how to specify operator training in an RECD purchase order, module by module, with a sample clause you can adapt and the common traps to avoid.

Why RECD Training Needs Its Own PO Clause

A Retrofit Emission Control Device changes how a generator should be watched and maintained. Before the retrofit, the exhaust was a pipe. After it, the exhaust contains a component whose condition affects engine health, compliance status and safety. If you want a refresher on the device itself, see what an RECD is and how it works.

That change affects people who were never part of the purchase discussion:

• Shift operators who start and stop the set
• Maintenance technicians who service the engine and exhaust
• The facility or EHS person who answers to the pollution control board
• Security or housekeeping staff who may be first to notice smoke or a leak

Poorly trained operators are a leading cause of avoidable RECD problems: ignored backpressure warnings, skipped cleaning, unsafe handling of hot surfaces, and missing records during inspections. A clear training clause is cheap insurance against all of them.

Step 1: Define Who Must Be Trained

Training aimed at “operators” usually reaches one or two people. Instead, list every role that interacts with the generator, then decide what each one needs to know. A simple audience matrix in the PO, or its annexure, prevents disputes later.

Role	Typical number	Depth of training	Focus
DG shift operators (all shifts)	3 to 8	Practical, hands-on	Daily checks, readings, alarms, logbook
Maintenance technicians	2 to 4	Detailed	Inspection, cleaning, gasket and bellows checks, safe isolation
Electrical / facility supervisor	1 to 2	Detailed plus diagnostic	Interpreting trends, escalation, coordinating with vendor
EHS / compliance officer	1	Overview plus records	Documentation, inspection readiness, legal requirements
Facility or plant manager	1	Short briefing	What “normal” looks like, when to call the vendor, budget for upkeep
Security / housekeeping (optional)	As needed	Awareness only	Spotting smoke, leaks, hot-surface hazards

Specify the minimum number of participants per role, and require that every shift is represented. Night and weekend operators are routinely left out of commissioning-day training because they are not on site at the time.

Step 2: Specify the Training Content, Module by Module

Rather than writing “training on operation and maintenance,” list the modules. Each module should have a short learning outcome so you can check later whether it was delivered. Use the outline below as a starting point and adjust to your device and site.

Module 1: How the Installed System Works

Outcome: Participants can describe, in their own words, what the device does, where it sits in the exhaust, and why its condition matters to the engine.

Cover the exhaust path, the device’s main components, what it captures and how it is cleaned or regenerated, and how the installation differs from the old exhaust. Keep it visual and site-specific, using the actual installation rather than a generic slide.

Module 2: Daily and Pre-Start Checks

Outcome: Operators can complete the daily checklist independently and record results correctly.

Include visual checks for leaks and soot streaks at flanges, the condition of the flexible bellows, supports and clamps, insulation and guards, rainwater ingress, and any gauge or indicator readings. Integrate these with the existing generator routine rather than creating a separate ritual; our monthly maintenance checklist for diesel generators is a useful base to extend.

Module 3: Reading Backpressure and Other Indicators

Outcome: Operators can read the backpressure gauge or display, know the normal range for their set, and know which value requires escalation.

This is the most important module and the one most often skipped. Require the vendor to write the normal operating band and the action threshold on a laminated card fixed near the gauge. Background reading: how exhaust backpressure affects a DG set.

Module 4: Start-Up, Load and Shutdown Practices

Outcome: Operators understand which operating habits help or harm the device.

Cover warm-up practices, the effect of prolonged idling or very light loading, cold starts, and cool-down before shutdown where relevant. Sites with frequent short runs need extra attention here; see RECD selection for DG sets with frequent short start-stop cycles and can an RECD work reliably during cold starts.

Module 5: Recognising Abnormal Conditions

Outcome: Operators can identify warning signs and take the correct first action.

Include: visible smoke after warm-up, changes in exhaust sound, unusual smell, rising backpressure, engine power loss or hunting, overheating alarms, and leaks. Link each symptom to a first response (“reduce load and inform supervisor,” “shut down and isolate,” “log and monitor”). Our guides on black smoke, white smoke and blue smoke help operators distinguish engine problems from device problems.

Module 6: Routine Maintenance Tasks

Outcome: Maintenance technicians can perform the scheduled tasks the vendor considers within the owner’s scope, and know which tasks must be left to the vendor.

Define clearly which activities the site team may perform (inspection, external cleaning, gasket checks, retightening) and which require the vendor (internal cleaning, element replacement, recalibration). This boundary often decides warranty claims. Use the RECD maintenance guide to prepare questions in advance.

Module 7: Safety Around the Device

Outcome: All participants can identify the hazards and follow safe work practices.

Cover hot surfaces and burn risk, safe cool-down periods, lock-out and tag-out before work, working at height for elevated devices or sampling ports, confined or congested plant rooms, and personal protective equipment. Where relevant, reference your site’s existing safety procedures and guidance from bodies such as the Directorate General Factory Advice Service & Labour Institutes (DGFASLI). Site layout matters too; see insulation and heat shields in your RECD site plan and safe access to sampling ports on tall chimneys.

Module 8: Records and Compliance Readiness

Outcome: The compliance officer and supervisors know which records to keep, where to keep them, and what to show an inspector.

Cover the logbook format, running hour records, backpressure log, service reports, type approval and installation certificates, and the documents typically requested during inspections. Our article on what happens during a pollution control board inspection and the environmental compliance checklist for generator owners provide a useful structure.

Module 9: Escalation and Vendor Contact

Outcome: Everyone knows whom to call, how to log a complaint, and what information to give.

Include the vendor’s helpline, escalation contacts, ticket process and the information the vendor needs (set number, running hours, readings, photos). Tie this to the service commitments in your contract, covered in our guide on RECD service response commitments.

Step 3: Specify Duration, Format and Language

Vague training becomes short training. Fix the basics in writing.

• Minimum duration: For example, “not less than four hours of classroom and hands-on training for operators and technicians, plus a one-hour briefing for managers.” Larger or multi-set sites may need more.
• Number of sessions: At least two sessions, or one per shift, so that all shifts are covered.
• Location: On site, at the installed device, with the generator available to run during the practical part.
• Hands-on component: Specify that each operator must personally perform the daily checklist and take a backpressure reading during training.
• Language: Training and materials in a language the operators are comfortable with, for example Hindi and English, or the local language.
• Trainer qualification: The trainer should be the vendor’s commissioning or service engineer, not only a sales representative.

Step 4: Specify the Training Deliverables

Training leaves a trail. List what the vendor must hand over, and make delivery a condition of acceptance.

Deliverable	Format	Purpose
Operation and maintenance manual, site-specific	Printed copy plus PDF	Reference for operators and technicians
Daily checklist and logbook format	Printed pad plus editable file	Standardised daily records
Laminated quick-reference card at the DG set	Fixed near gauge	Normal ranges, action thresholds, helpline
Training presentation and photos of the installation	PDF	Refresher material and onboarding of new staff
Attendance sheet with names, roles, signatures	Signed copy	Evidence of who was trained
Competency assessment results	Signed sheet per participant	Evidence that learning occurred
Training completion certificate	Signed by vendor and owner	Formal closure of the training scope
Short video of key checks (optional)	Video file	Useful for multi-shift and remote sites

The site-specific manual matters. A generic product manual will not show your exhaust route, your gauge location or your access arrangements.

Step 5: Build In a Competency Check

Attendance proves presence. A short competency check proves understanding. It need not be formal or intimidating. A practical observation works well:

• The operator completes the daily checklist on the actual set while the trainer watches.
• The operator reads the backpressure and states whether it is normal.
• The operator describes the first action for two or three abnormal scenarios.
• The technician demonstrates safe isolation and an inspection.

Record a simple pass or “needs repeat” for each person. Specify in the PO that anyone not passing receives a repeat session at no extra cost.

Step 6: Tie Training to Project Milestones and Payment

Training slips when it has no consequence. Anchor it in the contract.

• Timing: Training to be completed after commissioning and before the final handover certificate is issued. Some buyers also require a short pre-commissioning briefing so operators can watch the commissioning tests.
• Acceptance: Final acceptance, or release of the retention amount, conditional on receipt of all training deliverables and the signed completion certificate.
• Punch list: Treat incomplete training as an open punch item. Our guide on closing an RECD project punch list before final handover explains how to manage it.

Step 7: Plan for Refresher Training and Staff Turnover

Operator turnover in plant rooms is high. A person trained during commissioning may have left within a year. Build continuity into the PO.

• Refresher session: One refresher, for example six or twelve months after commissioning, included in the price.
• Seasonal briefing: In regions with seasonal restrictions, a short refresher before the peak usage season is valuable. In NCR, that means before winter and the GRAP period; see GRAP stages 1 to 4 and what changes at each level.
• New staff: A rate for additional sessions, agreed now, so you do not negotiate under pressure later.
• AMC linkage: If an annual maintenance contract follows, include a short annual training session in its scope.

A Sample Operator Training Clause for an RECD Purchase Order

Adapt the wording below to your organisation’s contract style and have it reviewed by your legal or procurement team.

Clause [x]: Operator and Maintenance Training

[x].1 The Supplier shall provide on-site training on the operation, routine maintenance, safety and record-keeping of the Retrofit Emission Control Device supplied under this Order, as installed on DG Set(s) [identification].

[x].2 Training shall cover, at minimum, the modules listed in Annexure [T]: system overview; daily and pre-start checks; reading and interpreting backpressure and other indicators; start-up, loading and shutdown practices; recognising abnormal conditions and first response; routine maintenance within the Purchaser’s scope; safety around the device; records and compliance readiness; and escalation procedure.

[x].9 Additional training sessions requested by the Purchaser beyond the above shall be charged at Rs [amount] per session, valid for [period].

An Example Training Schedule for a Two-Set Site

Writing the schedule into an annexure removes any doubt about what “training” will look like on the day. The example below is for a commercial building with two DG sets, three operator shifts and an in-house maintenance team. Adapt the timings to your site.

Session	Audience	Duration	Content	Location
Pre-commissioning briefing	Supervisors, EHS, one operator per shift	45 minutes	System overview, what commissioning tests will show, safety zones during commissioning	Plant room
Session A (morning shift)	Operators, technicians	4 hours	Modules 1 to 7, hands-on daily checks and backpressure readings with set running	Plant room and DG set
Session B (evening shift)	Operators, technicians	4 hours	Repeat of Session A for second shift	Plant room and DG set
Session C (night shift)	Operators	2.5 hours	Condensed Modules 2, 3, 5 and 7, hands-on checks	Plant room and DG set
Records and compliance	EHS, facility manager, supervisor	1 hour	Module 8, logbook review, document file walkthrough	Office
Management briefing	Facility head	30 minutes	Normal operation, escalation, maintenance budget	Office
Competency checks	All operators and technicians	15 minutes each	Practical observation at the set	DG set

Notice that the night shift gets its own, shorter session rather than being asked to attend in the afternoon. Schedules that ignore shift patterns are the main reason night operators are never trained.

How to Judge Whether Training Actually Worked

The real test of training comes weeks after the vendor has gone. Two or three simple checks tell you whether it stuck:

• Look at the logbook after a month. Are readings recorded every day, on every shift, in the format agreed? Gaps usually point to a shift that was missed.
• Ask an operator to explain the quick-reference card. If they can tell you the normal band and the action threshold without reading it, training has done its job.
• Review the first escalation. When an operator first calls the vendor, did they give the set number, running hours, readings and photographs? If yes, Modules 5 and 9 worked.

If any of these checks fail, use the refresher session early rather than waiting for the twelve-month date.

Special Situations Worth Writing Into the PO

Unattended or Remote Sites

Telecom towers, pumping stations and remote warehouses may have no permanent operator. Training then shifts to the field technicians who visit periodically, and to whoever monitors alarms remotely. Specify training for the actual visiting team, and require the vendor to include remote indicators in the content. Our guide on RECDs for telecom sites and unattended operation covers this situation.

Outsourced Operators or AMC Contractors

If your DG sets are run by a facility management company or an AMC contractor, their staff must be trained, not just yours. Write in that the Purchaser may nominate third-party personnel. Also decide who owns the logbook. The trade-offs are discussed in in-house maintenance vs AMC for generators.

Multi-Site Organisations

For chains of hotels, hospitals or retail sites, consider a “train the trainer” model at one site, plus short sessions at each other site. Specify which sites get full training and which get abbreviated sessions.

Regulated Environments

In pharmaceutical, food or healthcare facilities, training may need to follow your quality system: approved training records, controlled documents and version control. State this in the PO so the vendor provides material in an acceptable format. See RECD for pharmaceutical plants and change control.

Common Mistakes When Specifying RECD Training

• “Training included” with nothing else. Leaves scope entirely to the vendor.
• Training only on commissioning day. Operators are distracted, the set may not be available, and other shifts are absent.
• Training managers instead of operators. The people who run the set at 2 a.m. need it most.
• Generic manuals. Not useful when something goes wrong on your specific layout.
• No backpressure threshold. Operators read a number but do not know what it means.
• No evidence. Without attendance and competency records, you cannot prove training happened, which matters both for disputes and inspections.
• No refresher. Knowledge evaporates as staff change.
• Payment released before training. Removes the vendor’s incentive to finish it properly.

How Training Connects to the Rest of the Contract

Training does not stand alone. It works with the other parts of a well-structured RECD purchase:

• Your approval note should mention that training is in scope, so the cost is approved upfront.
• Your vendor evaluation should check, at reference sites, whether operators were properly trained. See how to evaluate a vendor’s RECD reference installation.
• Your service commitments determine what happens when trained operators escalate a problem.
• Your punch list process ensures training is not quietly dropped at the end.

Frequently Asked Questions

How long should RECD operator training take?

For a typical single-set installation, a half day covering both classroom and hands-on elements is a reasonable minimum for operators and technicians, plus a short management briefing. Multi-set sites, complex layouts or regulated facilities may need more.

Should training be charged separately?

Basic operator training is usually included in the supply and installation price. What matters is that its scope is written down. Additional or refresher sessions can be priced separately at a pre-agreed rate.

Can training be delivered online?

The classroom part can be online for refreshers or remote sites, but the initial hands-on part should be on site at the installed device. Reading a gauge and checking a bellows are physical skills.

Who should sign the training completion certificate?

The vendor’s trainer and the owner’s responsible engineer or facility manager. Attach the attendance sheet and competency records.

What if our operators change after training?

Use the refresher session, the recorded training material and the quick-reference card to onboard new staff. Agree a rate for additional sessions in the PO so you can call the vendor back without fresh negotiation.

Does training affect warranty?

It can. Many warranty terms exclude damage from improper operation or maintenance. Documented training, combined with proper logbooks, strengthens your position if a warranty claim is ever disputed.

Final Thoughts

An RECD is only as good as the people looking after it. Specifying training properly costs a few paragraphs in the purchase order and a few hours on site, and it protects the investment, the engine and your compliance record for years. Define the audience, list the modules, fix duration and language, demand evidence, test competence and link it to payment.
