| RE: | Workplace Chemical Exposure — Thermal Paper Receipts |
This memo is to bring your attention to a documented occupational health concern affecting retail cashiers. Thermal paper receipts used in most point-of-sale systems contain bisphenol compounds (BPA or BPS) — chemicals classified as endocrine disruptors by multiple health agencies.
1. The Regulatory Context
Washington State enacted a full ban on bisphenols in thermal paper effective 2026 (RCW 70A.222). California AB 1604 is currently pending, which would extend similar protections statewide. These laws reflect a growing scientific consensus that receipt chemical exposure poses a measurable health risk to workers who handle receipts daily.
2. The Risk to Your Staff
- Cashiers handle hundreds of receipts daily, resulting in significantly higher bisphenol exposure than the general population.
- Dermal absorption increases by up to 100× when hands are wet with sanitizer or lotion at time of contact.
- “BPA-Free” paper typically contains BPS, which carries equivalent health risks — the label does not indicate a safer product.
3. Recommended Actions
Listed from lowest to highest cost.
Instruct staff to dry hands fully before handling receipts, and to handle receipts from the edges or unprinted back side. No procurement required.
Provide thin nitrile gloves at point-of-sale stations. Note: vinyl and latex gloves are not effective — bisphenols penetrate them. Use nitrile only.
Switch to phenol-free thermal paper such as Blue4est or equivalent. Pricing is comparable to standard thermal paper and eliminates bisphenol exposure at the source.
