The Exposure Is Wider Than Most People Think
When researchers and journalists discuss bisphenol exposure from thermal paper, the conversation almost always centers on retail cashiers. And for good reason — a cashier at a busy supermarket may handle 300 to 500 receipts in a single shift.
But thermal paper is not just used for point-of-sale receipts. It is the printing technology of choice wherever a fast, ink-free, low-maintenance printout is needed. That means thermal paper shows up in hospitals, optometry clinics, pharmacies, parking garages, courthouses, shipping warehouses, and dozens of other environments — and the people working in those environments are handling it every day, often without knowing what it contains.
This article documents every major use of thermal paper we have identified, and the workers most exposed in each setting.
Part 1: Retail and Food Service
Cashiers and Checkout Staff
The most studied group. Supermarket, pharmacy, department store, hardware store, and convenience store cashiers handle point-of-sale receipts continuously throughout their shifts. Studies have measured urinary BPA levels in cashiers at two to three times the levels found in non-cashier workers. The combination of high receipt volume, frequent hand sanitizer use, and the tactile nature of the job (handling the receipt, tearing it, handing it to the customer) creates the highest-exposure occupational scenario documented in the literature.
Restaurant and Café Staff
Kitchen order tickets in many restaurants are printed on thermal paper. Servers, line cooks, and expeditors handle these tickets repeatedly throughout service. In high-volume kitchens, a single cook may handle dozens of order tickets per hour. Many kitchens also use thermal paper for table checks, delivery manifests, and credit card processing slips.
Food Delivery Drivers
Delivery platforms and restaurant POS systems commonly print thermal paper manifests, packing slips, and order confirmations. Drivers handle these documents at pickup and often again at delivery. Those working for multiple platforms simultaneously may handle dozens of thermal printouts per shift.
Deli and Butcher Counter Staff
Deli scales and meat department scales in supermarkets print thermal paper weight and price labels. Staff handle these labels repeatedly throughout the day, pressing them onto packaging by hand.
Bakery Staff
In-store bakery scales produce thermal labels for custom orders and pre-packaged items. Staff handle these labels continuously during production and packaging.
Part 2: Healthcare and Clinical Settings
Pharmacists and Pharmacy Technicians
Pharmacy prescription labels are commonly printed on thermal label paper. Pharmacists and technicians handle dozens to hundreds of prescription labels per shift — pressing them onto bottles, checking them, filing them. Pharmacy staff also frequently use hand sanitizer as part of infection control protocols, dramatically increasing their absorption risk with every label handled.
Optometrists and Optometry Staff
This is one of the least-recognized high-exposure groups. Multiple instruments in a standard optometry practice produce thermal paper printouts:
- Lensometers (focimeters): Print thermal paper readings of existing lens prescriptions. A busy optometrist may run a dozen or more lensometer printouts per hour during frame checks and prescription verifications.
- Autorefractors: Print thermal paper objective refraction measurements for every patient.
- Non-contact tonometers (air puff): Many models print thermal paper intraocular pressure readings.
- Corneal topographers: Print thermal paper corneal mapping results.
- Visual field analyzers: Print lengthy thermal paper perimetry reports.
An optometrist seeing 20 patients per day may handle 60 to 100 thermal paper printouts — and optometry practices have among the highest hand sanitizer usage rates of any clinical setting due to the close-contact nature of the work.
Audiologists
Audiometry equipment commonly produces thermal paper printouts of hearing test results (audiograms). Audiologists handle these printouts for every patient and frequently annotate them by hand, requiring extended contact with the paper surface.
Electrocardiogram (ECG/EKG) Technicians
ECG machines in hospitals, clinics, and cardiology offices almost universally use thermal paper for their printouts. A single 12-lead ECG produces a multi-page thermal paper strip. Cardiac monitoring units, Holter monitor reports, and stress test printouts are also commonly thermal. ECG technicians in busy hospitals may handle dozens of these printouts daily.
Ultrasound Technicians (Sonographers)
Ultrasound machines commonly use thermal paper printers for producing still-image printouts during examinations. Sonographers handle these printouts for every examination, and in obstetric settings, patients often want multiple copies — increasing the number of sheets handled per appointment.
Nurses and Clinical Staff
Vital signs monitors, infusion pumps, and bedside monitoring equipment in hospital settings frequently print thermal paper strips showing readings and alarms. Nurses document, file, and handle these strips throughout their shifts. In ICU settings especially, the volume of printed monitoring data can be substantial.
Physical Therapists and Rehabilitation Staff
Some electromyography (EMG) equipment and biofeedback devices used in rehabilitation settings produce thermal paper output. Staff handling these printouts in high-volume rehabilitation clinics accumulate meaningful exposure.
Veterinarians and Veterinary Technicians
Veterinary practices use the same diagnostic equipment as human medicine — ECG machines, ultrasound units, blood analyzers — and these commonly produce thermal paper output. Veterinary staff handle these printouts while also using hand sanitizer frequently due to biosecurity protocols.
Part 3: Transportation and Logistics
Airline Gate and Check-in Staff
Boarding passes printed at airport kiosks and check-in counters are thermal paper. Gate agents handle hundreds of boarding passes per flight — scanning them, tearing them, returning stubs. At busy hubs, a gate agent may process several flights per shift.
Baggage Handlers
Baggage tag labels used by most airlines are thermal paper. Ground crew attach these labels to bags by hand throughout their shifts.
Taxi, Rideshare, and Limousine Drivers
Receipt printers in taxis and rideshare vehicles produce thermal paper. Drivers who process cash transactions and print receipts handle these throughout their shift.
Parking Attendants and Garage Staff
Parking garage tickets and exit receipts are almost universally thermal paper. Attendants at staffed booths handle these continuously. Automated systems that require attendant assistance for validation also produce thermal paper.
Shipping and Receiving Staff
Shipping labels produced by major carriers (FedEx, UPS, USPS, DHL) are thermal paper labels. Warehouse staff in high-volume shipping operations attach, handle, and process hundreds of these labels per shift. Packing slips included in shipments are frequently thermal paper as well.
Train and Transit Staff
Ticket conductors on commuter and intercity rail handle thermal paper tickets throughout their shifts. Transit fare inspectors similarly handle thermal paper tickets and receipts.
Part 4: Financial Services
Bank Tellers
ATM receipts and bank counter transaction receipts are thermal paper. Bank tellers process transaction receipts for every cash transaction, wire transfer, and deposit. In busy branches, this can amount to hundreds of receipts per day.
ATM Technicians
Technicians who service and restock ATMs handle large rolls of thermal paper and process test printouts during maintenance visits.
Lottery and Gaming Staff
Lottery ticket receipts, gaming machine printouts, and casino cash-out tickets are thermal paper. Staff at lottery retailers and gaming facilities handle these continuously.
Part 5: Legal, Government, and Administrative Settings
Court Reporters and Court Staff
Many courthouses use thermal paper for timestamped document receipts, docket printouts, and fee receipts. Court clerks handle these throughout their working day.
Law Enforcement
Police officers issue thermal paper citations, parking tickets, and field interview cards from handheld printers. Traffic enforcement officers may issue dozens of thermal paper tickets per shift. Evidence receipt tags in some jurisdictions are also thermal paper.
Government Benefits and Social Services Staff
Benefits offices and social services agencies use thermal paper for queue tickets, appointment receipts, and transaction confirmations. Staff in high-volume offices handle these continuously.
Part 6: Event and Entertainment Venues
Box Office and Ticketing Staff
Event tickets printed at venue box offices and will-call windows are frequently thermal paper. Staff process these tickets for every transaction and handle returned stubs at entry gates.
Casino and Gaming Floor Staff
Beyond the cash-out tickets mentioned above, casino dealers and floor staff handle thermal paper player tracking receipts, comp vouchers, and transaction slips throughout their shifts.
Part 7: The Compounding Factors
Several factors make certain workers' exposure especially significant:
Hand sanitizer use: Healthcare workers, food service staff, and anyone in a setting with infection control protocols uses hand sanitizer frequently. As documented in our Cashier's Safety Guide, this can increase dermal absorption of bisphenols by up to 100 times (Hormann et al., 2014) compared to dry hands. A hospital nurse who uses sanitizer 20 times per shift and handles thermal paper printouts each time has a dramatically higher exposure than their sanitizer use frequency alone would suggest.
Extended handling: Workers who annotate, sort, file, or fold thermal paper — rather than simply passing it along — have longer skin contact time and higher exposure.
Heat and humidity: Thermal paper releases more bisphenol compound when warm. Workers in hot kitchen environments, or who store paper in warm pockets, may face higher transfer rates.
Lack of awareness: Unlike cashiers, who have been the subject of public health campaigns and some workplace safety discussions, most of the workers in this article have never been informed that the paper they handle contains endocrine-disrupting chemicals. This means they have taken no protective measures whatsoever.
For anyone in these groups who is planning a family or concerned about reproductive health, the research on bisphenols and fertility is worth reading in full.
Part 8: What Every At-Risk Worker Can Do
Regardless of your industry, the protective measures are the same:
The Dry Hands Rule: Never handle thermal paper immediately after using hand sanitizer or lotion. Wait until hands are completely dry — at least 5 minutes.
Backside Handling: The bisphenol coating is on the printed (shiny) side. Handle printouts from the unprinted back where possible.
Nitrile Gloves: High-dexterity nitrile gloves provide a complete barrier. They are available in sizes suitable for fine work including clinical and laboratory settings.
Advocate for Phenol-Free: Ask your employer, equipment supplier, or institution to switch to phenol-free thermal paper. For medical equipment printouts, contact the device manufacturer to ask whether phenol-free paper is compatible with your equipment. You can check whether your employer has switched using our 2026 Retailer Receipt Paper Scorecard.
Digital Alternatives: Many of the thermal paper uses described in this article have digital alternatives. Electronic health records reduce the need for printed diagnostic output. Digital receipts eliminate point-of-sale paper. E-tickets replace paper event tickets. Advocating for digital workflows where they exist is the most complete solution.
A Note on Research Gaps
The cashier population has been studied. Most other groups in this article have not. The absence of published research on bisphenol exposure in optometrists, ECG technicians, or parking attendants does not mean the exposure is absent — it means no one has looked yet. The thermal paper these workers handle contains the same chemicals as receipt paper. The skin absorption pathway is the same. The hand sanitizer interaction is the same.
The occupational health research community has significant work to do. In the meantime, the precautionary measures described above are available to every worker in every industry — and they cost almost nothing to implement.
