1.Title Block & Document Control

SOP Title {{SOP Title}}
SOP ID {{SOP ID}}
Version {{Version}}
Effective Date {{Effective Date}}
Review Date {{Review Date}}
Document Owner {{Document Owner}}
Approver {{Approver}}

Keep this block on page one so anyone can audit the document at a glance. Set a Review Date 6–12 months out and assign a single Document Owner who is accountable for keeping it current.

2.Purpose

State in one or two sentences why this procedure exists and what result it delivers when followed correctly.

Write the “why”, not the steps. Example: “This SOP ensures every customer refund is processed accurately, within policy, and within two business days.”

3.Scope

Define which teams, locations, systems, and situations this SOP applies to — and explicitly note what it does not cover.

Naming the boundaries prevents the procedure from being applied to the wrong cases. List any exclusions on their own line.

Preventive Maintenance Schedule

Asset / equipmentMaintenance taskFrequencyOwner
{{Asset ID / name}}{{Inspection or service task}}{{Daily / Weekly / Monthly / Quarterly}}{{Technician / role}}
{{Asset}}{{Task}}{{Frequency}}{{Owner}}
{{Asset}}{{Lubricate / replace / calibrate}}{{Frequency}}{{Owner}}

List each asset and the recurring task that keeps it running, with a frequency based on hours, cycles, or the manufacturer’s schedule. A PM schedule you actually follow is what prevents the breakdowns that cost the most.

Work Order Priority & Response

PriorityDefinitionResponse target
{{Emergency}}{{Safety risk or full stoppage}}{{Immediate}}
{{Urgent}}{{Degraded but running}}{{Same day / 24h}}
{{Routine}}{{Scheduled or minor}}{{Next PM window}}

Classify each request so the most important work goes first. Log every job — planned and reactive — in your CMMS or work-order log so history, parts, and downtime are traceable.

4.Definitions & Abbreviations

TermDefinition
{{Term}}{{Plain-language definition}}
{{Abbreviation}}{{What it stands for}}

Only define terms that could be misread by someone new to the process. If there are none, keep this section and write “None” — auditors expect it to exist.

5.Roles & Responsibilities

RoleResponsibility
{{Role}}{{What this role is accountable for in this procedure}}
{{Role}}{{What this role is accountable for in this procedure}}

Assign responsibilities to roles, not named individuals, so the SOP survives staff changes. Keep each role to one or two lines.

6.Prerequisites, Materials & Equipment

  • {{Access or permission required before starting}}
  • {{Tool, system, or login needed}}
  • {{Material or document that must be on hand}}

List everything that must be ready before step one. A short checklist here prevents half-finished runs.

7.Safety & Compliance

Note any safety precautions and the regulations or internal policies this procedure must comply with.

If this procedure has no safety or compliance angle, keep the section and write “N/A”. Reference the specific policy or regulation by name where one applies.

8.Procedure (Step-by-Step)

StepActionOwnerExpected Result
1{{Start with a verb — one action per step}}{{Role}}{{What “done right” looks like}}
2{{Next action}}{{Role}}{{Expected result}}
3{{Next action}}{{Role}}{{Expected result}}

Aim for roughly 5–15 numbered steps. Begin each with a verb, keep it to one action, and make the Expected Result observable so anyone can confirm the step is complete.

9.Quality Checks & Acceptance Criteria

  • {{Measurable check that confirms the work was done correctly}}
  • {{Second acceptance criterion}}

Write 2–4 checks that are measurable — a reviewer should be able to answer each with a clear yes or no.

10.Troubleshooting & Exceptions

Failure scenarioWhat to doEscalate to
{{Common thing that goes wrong}}{{Corrective action}}{{Role / contact}}
{{Edge case}}{{How to handle it}}{{Role / contact}}

Capture the failures you have actually seen. Naming the escalation point keeps exceptions from stalling.

A worked example for quarterly preventive maintenance of rooftop HVAC units at a facility.

1.Title Block & Document Control

SOP Title Rooftop HVAC Preventive Maintenance
SOP ID MNT-022
Version 1.0
Effective Date June 1, 2026
Review Date June 1, 2027
Document Owner Maintenance Supervisor
Approver Facilities Manager

2.Purpose

This SOP keeps the rooftop HVAC units running efficiently and prevents unplanned failures by performing scheduled preventive maintenance, so comfort, air quality, and energy cost stay under control.

3.Scope

Covers quarterly preventive maintenance of the packaged rooftop units (RTUs) at the main facility. It does not cover refrigerant repairs requiring an EPA-certified technician (MNT-030) or controls/BAS programming, which the contractor handles.

5.Roles & Responsibilities

Maintenance SupervisorSchedules PMs, reviews work orders, orders parts
Facilities ManagerApproves the SOP and the maintenance budget

6.Prerequisites, Materials & Equipment

  • Open work order in the CMMS for the asset
  • Correct filters, belts, and lubricant on hand
  • Ladder/roof-access permit and fall-protection gear
  • Multimeter, gauges, and basic hand tools
  • LOTO locks and tags

7.Safety & Compliance

Follow the roof-access and fall-protection policy. Confirm the unit is in a safe state before opening panels. Recover refrigerant only if EPA Section 608 certified — otherwise stop and create a separate work order.

8.Procedure (Step-by-Step)

9.Quality Checks & Acceptance Criteria

  • All scheduled PM tasks completed and logged in the CMMS
  • Operating readings (temperature split, amp draw) within the expected range
  • No active alarms or refrigerant leaks observed
  • Work order closed with parts and labor recorded

Frequently asked questions

What should a maintenance SOP include?

A maintenance SOP should cover a preventive-maintenance (PM) schedule listing each asset, task, and frequency; how work orders are prioritized and logged; the step-by-step procedure; and lockout/tagout safety. This template includes a PM schedule and a work-order priority table on top of the standard SOP sections, with a worked HVAC example.

What is preventive maintenance?

Preventive maintenance (PM) is scheduled, recurring work — inspections, lubrication, filter and part changes — done to keep equipment running and prevent failures, based on time, hours, or cycles. It contrasts with reactive maintenance, which fixes things after they break. The template’s PM schedule is where you list each asset and its interval.

What is the difference between preventive and reactive maintenance?

Preventive maintenance is planned work done on a schedule to avoid breakdowns; reactive (corrective) maintenance is unplanned work to fix something that has already failed. A good program does most work as PM and logs the reactive jobs as prioritized work orders — both of which this SOP supports.

Does a maintenance SOP need lockout/tagout?

Yes. Any procedure that involves servicing equipment should reference lockout/tagout (LOTO) per OSHA 29 CFR 1910.147, isolating every energy source before work begins. This template includes a LOTO safety note; adapt it to the specific energy sources on your equipment.
