Sterilization traceability in a Dutch tattoo studio is not a luxury — NEN-EN 17169:2020 has been the designated safety code under the Warenwetbesluit on tattooing and piercing since 1 May 2022 (Stcrt. 2022, 4132). NVWA supervision reports for 2024 show that roughly half of unannounced inspections found one or more shortcomings — sterilization documentation is a recurring issue. This guide details every step, from instrument intake to archiving the cycle record, for a studio that is always ready for a GGD or NVWA visit.
At the end of each session, reusable instruments (tubes, grips, forceps) are immediately placed in a pre-disinfection tray with enzymatic or detergent-disinfectant solution. Single-use instruments (needles, tips, ink cups) are disposed of in the regulated waste container according to the LCHV hygiene guideline for tattooing. Never mix the two categories. Immediate separation protects staff during subsequent handling and prevents cross-contamination.
After pre-disinfection (duration depends on the product, typically 15-30 minutes), instruments are rinsed with clean water, thoroughly dried, and placed in sterilization pouches (heat-sealable paper/plastic). Each pouch is sealed and marked with a process indicator (autoclave tape). Thorough drying before packaging is essential -- moisture trapped inside a pouch compromises packaging integrity and sterilization efficacy.
Pouches are loaded into the autoclave following the manufacturer's loading instructions (do not overload, do not stack pouches). The recommended cycle is 134 degrees C for 18 minutes (prion cycle). The autoclave generates a report at the end of the cycle -- this report is the proof that sterilization parameters were reached. NEN-EN 17169:2020 ("Tattooing -- Safe and hygienic practice", designated as the safety code since 1 May 2022 via Stcrt. 2022, 4132) and NEN-EN 13060 (class B autoclave) are the applicable standards for Dutch tattoo studios.
Before the first load of the day, run a Bowie-Dick or helix test to verify steam penetration.
After the cycle, each pouch receives a traceability label showing: the cycle number, the sterilization date, the use-by date (typically 1-2 months for a single-layer pouch), and the identification of the contents. With traceability software like SecuSteri, the label includes a QR code linking the pouch directly to the autoclave cycle report.
The pouch is opened in front of the client to demonstrate that the instrument is sterilized and within its use-by date. This is particularly important in tattoo and piercing, where client trust depends on process transparency.
Sterilized pouches are stored in a clean, dry, enclosed space away from dust. The first-in, first-out (FIFO) principle applies: the oldest pouches are used first. The storage area must be separated from the work area -- the LCHV hygiene guideline requires a clear separation between the contaminated zone (pre-disinfection), the clean zone (packaging and autoclave), and the sterile storage area.
Each cycle is recorded with: date, time, cycle number, parameters (temperature, pressure, duration), result (pass/fail), and operator identity. The autoclave report is retained (in paper or digital format). For patient-record-linked sterilizations the 20-year WGBO retention applies (BW Article 7:454, in force since 1 January 2020). The reprocessing protocol must clearly define documentation obligations.
Additionally, each tattoo or piercing session must document: client data (name, identification document, signed informed consent), description of the work performed, instruments used (with reference to the sterilization cycle), inks or products used (batch number, manufacturer, traceability per REACH Annex XVII Entry 75 -- EU Regulation 2020/2081), and any incidents.
The Dutch regulatory framework for tattooing and piercing is nationally uniform -- there is no provincial or regional variation. The Warenwetbesluit on tattooing and piercing (BWBR0021605, Stb. 2007, 114), in force since 1 June 2007, governs permitting and hygiene requirements at the national level. The Warenwetregeling on tattooing and piercing (BWBR0021915) contains the implementing rules. NEN-EN 17169:2020 has been designated as the safety code since 1 May 2022 via Stcrt. 2022, 4132 -- this is the operational technical standard. The LCHV hygiene guideline for tattooing and piercing (National Center for Hygiene and Safety, RIVM) is the practical implementation guide.
Every studio needs a three-year permit from one of the 25 GGD regions (mandated by the Ministry of VWS). The NVWA exercises national supervision on inks and colorants under REACH Annex XVII Entry 75 (EU Regulation 2020/2081). Tattoo artists who work at conventions in other regions face the same national standard -- a digital, portable register like SecuSteri lets you demonstrate compliance to any GGD inspection or NVWA visit, regardless of region.
NVWA supervision reports for 2024 show that roughly half of unannounced tattoo studio inspections found one or more shortcomings -- sterilization documentation being a recurring item. At the three-year permit renewal the GGD also checks that batch documentation is complete and searchable.
Not filling in the record immediately after the cycle (forgetting). Not marking the use-by date on the pouch. Storing pouches in an open or humidity-exposed drawer. Not performing the daily Bowie-Dick test. Not keeping autoclave reports. Using a pouch past its use-by date without reprocessing. Not documenting inks with batch number and REACH traceability. Not obtaining informed consent from the client before each session.
