Editorial Standards

Opora Supply www.oporasupply.com Effective Date: June 2, 2026

Opora Supply publishes educational content for building service contractors (BSCs), facility managers, EVS managers, and procurement officers. This page describes the editorial standards that govern everything published on the Site: how we source information, how we verify it, when we update it, and how we handle errors. These standards are the public-facing complement to our internal Voice & Style Guide and are binding on all writers, editors, and contractors who contribute to the Site.

Questions about these standards: Contact us

1. Our editorial mission

Opora Supply exists to give cleaning industry operators the same quality of sourced, specific, regulation-grounded information that finance professionals get from Bloomberg or the Economist — applied to the decisions that actually govern a BSC's operations: labor costs, chemical compliance, bidding, workforce management, and facility-specific operational protocols.

This means:

  • Every claim that can be sourced is sourced — to a primary government or standards-body document, not to a news article that cited a study that cited the original source.
  • Specificity is the standard. "A typical production rate" is not acceptable. "1,200 square feet per hour for restroom cleaning under ISSA 447 production rate tables, adjusted for traffic class" is.
  • Regulation citations include the code section. "OSHA requires..." is not a citation. "OSHA 29 CFR 1910.1030(d)(2) requires..." is.
  • Content is written for operators who have priced a contract, argued with an insurer, and managed a crew — not for someone discovering the industry.

We do not publish content we cannot source. We do not publish claims we cannot verify. We correct errors when they are found.

2. Sourcing standards

2.1 Primary sources required

Every factual claim — a rate, a regulation, a benchmark figure, a deadline — must be sourced to a primary source wherever one exists. The primary source hierarchy for Opora Supply content is:

  • Labor and wage data: U.S. Bureau of Labor Statistics (BLS) — specific series, survey, and date required
  • Workplace safety regulations: OSHA — 29 CFR section and subsection required
  • Environmental regulations: EPA — specific rule, list, or database citation required
  • Workers' compensation rates and classification: NCCI or applicable state rating bureau
  • Industry production rate standards: ISSA — specific document title, edition, and section required
  • Demographic and business count data: U.S. Census Bureau — specific survey and vintage year required
  • State labor law and minimum wage: Applicable state Department of Labor — with effective date
  • State environmental regulations: Applicable state environmental agency — with effective date
  • PFAS restrictions: State environmental or consumer protection agency — verified against current regulatory text
  • VOC limits: Applicable state air quality management district

Secondary sources — trade publications, industry association reports, third-party surveys — are permitted only when:

  1. No primary government or standards-body source covers the claim, and
  2. The secondary source is identified as such in the article, and
  3. The secondary source itself cites its methodology and data vintage.

Secondary sources are labeled in the article. We do not pass off trade press statistics as primary-source data.

2.2 No data from aggregators without primary backup

We do not cite data aggregators (data.world, Statista, industry blog roundups, etc.) as sources, even when they compile government data. We go to the primary source. If the primary source is unavailable at the time of publication, we wait or omit the claim.

3. Citation policy

3.1 Inline citation format

Citations appear inline, immediately after the claim they support — not in a footnote block or bibliography at the end of the article. The citation is a markdown link with descriptive anchor text.

The anchor text describes the source or the specific data being cited. It never says "source," "click here," "learn more," or any generic navigation phrase. The sentence reads naturally with the link removed.

Correct:

"The median hourly wage for janitors and building cleaners was as of May7.71 as of May 2024, per BLS Occupational Employment and Wage Statistics, NAICS 561720."

Incorrect:

"Wages have risen in recent years (source)."

3.2 Date specificity required

Every citation of data includes the data vintage — not just the source name. "BLS data" is not a citation. "BLS Occupational Employment and Wage Statistics, May 2025" is.

For regulatory citations: include the effective date or most recent amendment date where available.

3.3 Publication date and last-reviewed date on articles

Every article published on the Site carries:

  • A Published date (original publication)
  • A Last reviewed date (date of most recent editorial review, even if no changes were made)

These dates are visible on the article page. They allow readers to assess source currency themselves.

4. Fact-checking process

No article is published without completing a two-pass editorial review:

First pass (writer self-review):

  • Every statistic verified against the primary source cited
  • Every regulation citation checked against the current regulatory text at the issuing agency
  • Every production rate figure verified against the stated ISSA source or equivalent
  • Every date (effective dates, data vintages, amendment dates) confirmed
  • Calculations reviewed for arithmetic accuracy

Second pass (editor review):

  • A separate editor independently verifies every numeric claim and regulation citation
  • Internal cross-links confirmed to resolve to the correct destination
  • Disclaimer overlay assigned and confirmed correct for content category
  • Article structure, headers, and citation format reviewed against the Voice & Style Guide

An article that fails second-pass review returns to the writer. It is not published with known errors and a plan to fix them later.

5. Update cadence

Content accuracy degrades over time as regulations change, wage data is updated, and industry conditions shift. We operate on a defined update schedule:

  • General operational articles (bidding, labor management, workforce): Annually — each article reviewed within 12 months of last review date
  • Regulatory content (OSHA, EPA, PFAS, VOC, state labor law): Quarterly — or immediately upon notification of regulatory change
  • Tool and calculator methodology pages: On data-source release cycle — e.g., BLS OEWS updates trigger wage rate refresh in tools that use wage inputs
  • Benchmark content ($/sqft, production rates, bid margins): Annually at minimum; more frequently when primary data sources publish new vintages
  • Glossary entries: Annually

When a review results in a substantive change to published content, the Last Reviewed date is updated. When the change corrects a factual error, the Corrections Policy governs the notice process.

6. Corrections handling

When a factual error is identified — whether through our own review process, a reader report, or a change in the underlying source — we correct it. The full process is described in the Corrections Policy.

The short version:

  • Typos and formatting errors: silent fix.
  • Non-material factual errors (e.g., a misattributed statistic that does not affect a reader's decision): visible correction notice at the article footer.
  • Material factual errors (errors that could affect a business or compliance decision): visible correction notice, notation in the public corrections log, and email notification to subscribers when applicable.

Editorial staff who identify a potential error in their own prior work are expected to flag it immediately. Suppressing an error is not an option.

7. Conflict of interest

Opora Supply is an editorially independent publisher. Our editorial decisions are not influenced by commercial relationships.

Specifically:

  • No paid placement: We do not accept payment to mention, feature, or review any product, vendor, or service in editorial content. Mentions of named vendors (chemical manufacturers, software providers, equipment brands) in editorial content are factual references — not placements.
  • No vendor sponsorship of articles: Article topics are chosen based on reader relevance and search demand, not sponsor relationships.
  • Affiliate disclosure: Where Opora Supply earns a referral fee or commission from a product link (including Shopify product pages), that relationship is disclosed in the article using the label: "Opora Supply may earn a commission on purchases made through links in this article."
  • Product comparisons: Feature comparisons of software, equipment, or services are built on factual feature matrices — not on vendor-supplied marketing materials. Vendors may be asked to verify factual accuracy, but editorial conclusions are our own.
  • Opora Supply products: Where we reference our own tools or products in editorial content, we note the relationship. Editorial content is not written to drive sales of specific Opora Supply products — it is written to inform readers.

8. Byline policy

Standard byline: Opora Editorial Team

All content published on www.oporasupply.com carries the collective byline "Opora Editorial Team." This reflects our editorial review process: every published piece is the product of research, drafting, and at least two editorial review passes — not a single author's unreviewed work.

Individual contributor names are not published in bylines. The editorial team's credentials and review process are disclosed on the Methodology page.

Guest contributions: The Site accepts guest contributions from industry practitioners (licensed safety professionals, insurance specialists, operations consultants) on a selective basis. Guest contributions:

  • Must meet the same sourcing, citation, and style standards as in-house content
  • Are edited by the Opora editorial team before publication
  • Carry a modified byline format: "Contributed by [Name, Credentials] — Reviewed by Opora Editorial Team"
  • May not use the byline or article to promote the contributor's products, services, or firm in editorial text (a contributor bio is permitted)
  • Are selected based on editorial relevance, not on the contributor's commercial interest in the topic

Guest contributions are rare. Inquiries: Contact us.

9. Reader trust

We publish corrections visibly. We disclose methodology. We cite primary sources. These are not marketing positions — they are the operational standards we hold ourselves to because our readers make real business decisions based on what they read here.

If you find an error, report it. We review every report. See the Corrections Policy for the process.

If you believe a sourcing decision or methodology choice is wrong, contact us. We explain our reasoning. If the reasoning is wrong, we fix it.

Reader trust is earned by doing the work correctly, not by claiming to.
