What's the difference between the Equipment Library and the Chemicals Library?

Equipment covers physical machinery — autoscrubbers, burnishers, extractors, vacs — including production rate math and warranty terms. Chemicals covers product chemistry — quat ammonium, hydrogen peroxide, sodium hypochlorite, peracetic acid — including dilution ratios, dwell times, EPA registration numbers, and surface compatibility. Most procurement decisions touch both.

Where do the pricing-by-facility numbers come from?

Three sources combined: ISSA production rate guidance (industry standard for cleaning times by surface and task), BLS Occupational Employment and Wage Statistics May 2024 release for janitor wages by metro, and an anonymized Opora benchmark database covering several thousand commercial cleaning accounts. Ranges are stated in cents per square foot per clean, with frequency and complexity tiers.

How often are library pages updated?

Chemical and equipment specs are updated when manufacturers change them — typically annually. Compliance pages update whenever a regulator issues new guidance, with OSHA penalty figures refreshed each January after the annual inflation adjustment. Pricing pages update each spring after BLS releases new OEWS wage data.

Why is there both a Compliance Library and a separate PFAS State Lookup tool?

The Compliance Library covers federal frameworks — OSHA 29 CFR 1910, EPA disinfectant registration, FDA Food Code, Joint Commission EPs, NFPA 654. The PFAS State Lookup is state-specific and changes frequently as legislatures act. As of 2026, twelve states have active PFAS legislation affecting cleaning chemistry, including California AB 1817, Maine LD 1503, and Minnesota HF 2310.

Is there a single index of every page on Opora?

Yes — start with this library hub for content libraries, the verticals hub for industry-specific pages, and the data hub for primary-source research. The by-metro and by-state indexes cover programmatic location pages. Combined, they expose every indexable page on the site.
