The Operative Sentence

What this publication does

Every claim here is a claim about what a document says. We retrieve the primary document — the codified rule, the agency letter of interpretation, the state administrative code, the sewer-use ordinance, the study — read it in full, print the sentence that does the work, and record the date we retrieved it. Where a document does not contain the thing everyone says it contains, we publish the keyword scan that shows it, with its method and its date. Where we could not obtain a document, we say that instead of paraphrasing someone who summarised it. Nobody who writes these pages has worked in an operating room, nothing here is legal or clinical advice, and this publication sells nothing and recommends nothing. How we work, and where it could be wrong, is set out at Method and Editorial standards.

Registers and the claims ledger

Registers are maintained tables, not articles. Every row carries its source, its citation, the verbatim primary text where one exists, the date we retrieved it, and one of four status labels. Rows are never deleted; a superseded row is struck, dated and replaced beneath. The status vocabulary is closed and is published at Editorial standards.

• State rules on liquid blood to the sanitary sewer

  Register A. What each state’s own administrative code or statute says, quoted, with the states we have not read published as rows.

• Sewer-use ordinances of large POTWs

  Register B. Eleven publicly owned treatment works, read for blood and for medical or infectious waste, with the retrieval method for each.

• State surgical-smoke statutes

  Register C. One row per enacted instrument: bill number, chapter or public-act number, signing date, effective date, and what is obligated. There is no enforcement column, and the register says why.

• Claims ledger

  One anchored row per circulating claim, traced hop by hop. A broken chain is a finding about the record, not about the world; every row also says what the record does support.

Articles

All ten are published. This is the slate we committed to before any of it was written, printed here so it can be held against us. Each carries the date it was published and the date it was last read against its own sources; when those two dates diverge, the second one is the one that matters.

1. OSHA’s bloodborne pathogens standard does not mention drains, sewers, solidifiers or pouring

   Its only disposal provision defers to state and local law, and the duty it does impose attaches to the technique of pouring, not the destination.

   AnswersDoes OSHA say whether surgical fluid waste may go down a drain?

2. Three layers of law decide whether blood may go to the sanitary sewer, and OSHA defers to all of them

   The answer is set by a state medical-waste rule, then by a sewer-use ordinance, then by facility policy — in that order.

   AnswersWho actually decides whether liquid blood may be poured into a sanitary sewer?

3. Six figures that anchor the surgical-waste business case, traced to the documents they came from

   Each figure is followed hop by hop to its source; several chains break, and the ones that hold are named with their limits.

   AnswersWhere did the numbers in every surgical-waste presentation actually come from?

4. The business case for fluid-management systems runs on a disposal price about a third of the current benchmark median

   Rebuilt on current primary inputs, with every assumption in a table a reader can override, and no method declared the winner.

   AnswersWhat does surgical fluid waste cost, and which assumptions move the number?

5. What makes something regulated waste is a definition in 1910.1030(b), and “it looks contaminated” is not in it

   The federal definition has five limbs, the compression test is only one of them, and state law adds to all five.

   AnswersWhat has to go in a red bag, and who decides?

6. What published guidance says happens after a blood or body-fluid splash to the eye

   A source-by-source account of what each retrieved guideline says, and what the employer must provide and pay for. We synthesise no schedule.

   AnswersWhat do the published guidelines say after a blood or body-fluid splash to the eye?

   Published 2026-08-06 · Last reviewed 2026-08-06

7. In the studies that looked, most operating-room blood exposures were not recognised by the people exposed

   The interesting number is not frequency but recognition — and the surveillance everyone cites is a convenience sample with no sampling frame.

   AnswersHow often does blood reach an operating-room worker’s face, and how often is it noticed?

   Published 2026-08-06 · Last reviewed 2026-08-06

8. How much fluid a surgical case produces, by procedure, from the published series

   Volumes assembled from the procedure literature, each with its n and its setting, so a reader can compute a number instead of estimating one.

   AnswersHow much fluid does a given procedure actually generate?

   Published 2026-08-06 · Last reviewed 2026-08-06

9. “Three-quarters full” is a manufacturer’s fill line, not an OSHA requirement

   The standard contains no percentage anywhere; the three-quarters line is moulded into the plastic, and that is a different obligation with a different route.

   AnswersWhere does the three-quarters rule for sharps containers come from?

10. State surgical-smoke laws mostly require a written policy, not a device — and the published count of twenty is out of date

    Sixteen of the seventeen operative mandates oblige a written policy rather than equipment, and two states on every tracker have no mandate at all.

    AnswersWhich states require surgical smoke evacuation, and what exactly do they require?
