Washing hands and hygiene: duties, methodology and evidence in the company

Handwashing is the single most effective measure for reducing infection transmission. The Robert Koch Institute has been pointing out in the KRINKO recommendations for years that correctly carried out hand cleaning can reduce the germ load by a factor of 10 to 1,000. In a business context, however, hand hygiene is not just a medical recommendation, but a documented obligation. It is specified in the Infection Protection Act (§§ 35 ff. IfSG), the Food Hygiene Ordinance (LMHV), the Workplace Ordinance (ArbStättV § 6) and the Technical Rule for Biological Agents TRBA 250. Violations lead to fines, in the food industry to company closures and in healthcare facilities to liability issues, which regularly affect the management personally in civil law proceedings.

This article explains which legal obligations regarding hand hygiene apply in the company, what the correct methodology looks like according to DIN EN 1499 and the KRINKO recommendation and how hygiene officers document enforcement in a audit-proof manner. As a compliance platform and officer-as-a-service, CIVAC supports hygiene officers in gastronomy, care, food production and industry with templates, training registers and control protocols. Licence the workspace for your internal representatives or have our representatives order it. You will find out which steps are involved in DIN-compliant hand washing, when disinfection is also required, how you can sanction violations in a robust manner without triggering labour law issues, and which gaps cause the most common audit complaints.

The legal obligation to practice hand hygiene is derived from several legal sources, the scope of which partly overlaps. In §§ 35 ff. IfSG, the Infection Protection Act requires regular instruction and verifiable hygiene practices for employees in communal facilities, in food processing as well as in medical and nursing facilities. The Food Hygiene Regulation refers to Regulation (EC) No. 852/2004, whose Annex II, Chapter VIII, regulates the personal hygiene of staff in contact with food. The Workplace Ordinance § 6 obliges employers to provide suitable washing and sanitary rooms, including the necessary cleaning agents and drying facilities.

Industry-specific details result from the Biological Substances Ordinance and TRBA 250 for activities with a risk of infection in the healthcare sector, as well as from TRBA 500 for general biological agents. In the healthcare sector, the recommendations of the Commission for Hospital Hygiene and Infection Prevention (KRINKO) are also relevant. Although they are formally only recommendations, they are considered the state of the art when it comes to liability issues. Non-compliance regularly leads to difficulties in providing evidence in civil disputes. In food production, IFS Food and BRCGS Global Standard supplement the regulatory requirements with auditable industry standards.

Hygiene officers coordinate the implementation of these obligations. The term is not defined in a single law, but results from the hospital hygiene regulations of the federal states, the medical device operator regulations and DIN 10514 for food production. CIVAC offers hygiene officers a complete set of notices, training templates, control checklists and reporting lines at civac.de/roles/hygienepflichter. The role is linked to all relevant legal references in the workspace, so that every measure is automatically assigned to a legal basis. When the law changes, the framework changes centrally without all notices having to be replaced manually.

The standard DIN EN 1499 describes the methodology of hygienic hand washing as a standardised procedure in six steps. Firstly, moisten your hands under running water, ideally between 35 and 38 degrees Celsius, because water that is too hot damages the skin barrier and water that is too cold worsens the dirt solution. Secondly, the absorption of liquid soap from a touch-free dispenser. According to the RKI recommendation, bar soap is not permitted in company hygiene plans because it acts as a reservoir for germs. Refillable open dispensers are also problematic because they can become contaminated; Disposable cartridges are the reliable choice here.

Thirdly, soaping the palms of the hands, fourthly, the back of the hand including the spaces between them, fifthly, the spread fingers and sixthly, the thumbs and fingertips. The total exposure time is at least 20 seconds, in food processing and healthcare, depending on the activity, 30 to 60 seconds. This is followed by rinsing with water, drying with disposable towels and, if necessary, operating the fitting using the disposable towel to avoid recontamination. This step is not necessary for sensor-controlled fittings. According to the RKI assessment, air dryers should be viewed critically in sensitive areas due to aerosol formation.

Hygiene officers should practice the process in practical training annually and not just teach it theoretically. Observations in practice regularly show that employees shorten the steps or vary the order, which significantly reduces the hygiene effect. CIVAC provides a training template in the workspace with an exercise routine, knowledge quiz and confirmation of participation. Audit-proof, documented, § 43 IfSG-proof. This receipt is anchored in the employee's training register and can be accessed immediately during the audit without having to search through paper folders. A training video loop with a demonstration of the sequence usefully complements the written instructions and increases retention performance.

Hand washing and hand disinfection are two different processes with different goals. Washing your hands removes visible dirt and reduces the transient germ flora on the skin surface through mechanical action. Hand disinfection with alcohol-based rubs in accordance with DIN EN 1500 reduces the number of germs significantly more and is also effective against many enveloped viruses. However, it does not replace mechanical cleaning when there is visible contamination. The order is therefore always: wash first, then disinfect if the activity requires it.

In food processing, cleaning is usually the priority because the transfer of contamination and gram-negative bacteria must be prevented. In healthcare, nursing and laboratories, disinfection before and after every patient contact is mandatory according to the KRINKO recommendations and follows the logic of the WHO's five indications. In industry and administration, regular hand washing is sufficient, provided there is no risk of contamination from hazardous substances or biological agents. In the event of contact with hazardous substances, skin protection preparations and, if necessary, special cleaners are also used, which are recommended in the safety data sheet.

Hygiene officers determine in the hygiene plan industry-specific which activity triggers which method. According to Section 36 IfSG, this plan is binding for reporting institutions. The choice of disinfectant is based on the list of the Association for Applied Hygiene (VAH list) or, in the case of officially ordered measures, on the list of the Robert Koch Institute. Procurement outside of these lists will be criticized in the audit. CIVAC maintains the approved resource lists in the workspace and alerts you when changes occur so that expired listings do not create unnoticed gaps in the hygiene plan. A specification for each activity makes it easier for purchasing to make the correct procurement and systematically eliminates proliferation in procurement.

The hygiene plan is the central document for implementing hand hygiene in the company. According to Section 36 IfSG, community facilities, medical and nursing facilities as well as accommodation providers must have a written hygiene plan. The LMHV requires an equivalent document for food processing companies as part of the HACCP concept. The content is partly stipulated by law and partly specified by professional recommendations from the professional associations and the Robert Koch Institute. An off-the-shelf template is useless because it does not reflect risk areas, rooms and work processes of the specific facility.

A complete hygiene plan contains at least nine components. Firstly, the responsibilities with the name and position of the hygiene officer. Secondly, the description of the premises with risk zones. Thirdly, personal hygiene with requirements for hand washing, disinfection, jewelry and work clothing. Fourth, the cleaning and disinfection plans for surfaces and equipment. Fifth, pest monitoring. Sixth, the training requirements and the training register. Seventh, the instructions according to Section 43 IfSG. Eighth, the reporting concept for outbreaks and infection events. Ninth, the audit and control concept with sampling plan and documentation templates.

Hygiene officers review the plan at least annually and after each relevant event. CIVAC provides 490 audit templates in the workspace, several of which are designed directly for hygiene plan maintenance. Others run compliance like a filing cabinet. We run it like software. Changes to the hygiene plan are versioned and documented with a date, signature and justification. In the audit, it is always possible to see which version was in force when and which reasons led to the adjustment. From this trace, the supervisory authority can see whether the plan is actually alive or whether it is a mandatory artifact without resonance in the company.

The instruction in accordance with Section 43 IfSG is mandatory for employees in food establishments and comparable establishments. It is carried out for the first time by the health authority before the start of work and then annually by the employer. The instructions include bans on activities in the event of certain illnesses, personal hygiene including hand hygiene, handling food and the obligation to report suspected cases. The employee may not be employed without verifiable instructions, which immediately leads to complaints in the audit. Seasonal workers and temporary workers are particularly susceptible to gaps in this documentation and require their own processes.

In medical facilities, the training requirement arises from Section 35 IfSG, TRBA 250 and the state regulations on hospital hygiene. The training there also includes the five WHO indications for hand disinfection, the use of personal protective equipment and the reporting channels in the event of outbreaks. The professional association for health services and welfare also recommends annual refreshers with observations at the workplace and feedback to employees. These observations are methodically documented in the Clean Hands campaign and provide comparative figures for internal benchmarks.

Hygiene officers either carry out the training themselves or commission external trainers. What is crucial is the verifiable participation of each employee with date, content and signature. CIVAC maintains the training register in the workspace with individual receipt, automatic deadline monitoring and reminders 30 days before the end of the annual refresher. The auditor calls, the evidence is ready. A missing receipt in the audit is equivalent to a lack of training, which is why continuous documentation is not an administrative burden, but rather legal protection for management. The platform exports individual training passes for each employee upon request.

An effective hand hygiene strategy does not end with notices and training. It requires regular controls, observations at the workplace and a documented audit concept. The compliance monitoring methodology has been established in hospital hygiene for years and is coordinated under the term Clean Hands Campaign at the Charité University Hospital. Hygiene officers record the number of hand disinfections required and the number actually carried out and use this to calculate a compliance rate. Values ​​below 50% are considered a need for action, values ​​above 80% are considered a good level, which is the target in many companies. A consumption measurement of the amount of disinfectant per patient day complements the direct observation and provides objective trend data.

In food processing, the controls are less formalized, but are carried out randomly by the official food monitoring authorities of the federal states. The inspectors pay attention to the condition of the washing areas, the availability of soap and disposable towels, the cleanliness of the dispensers and proof of training. Complaints are usually associated with short periods of time for improvement and, in the event of repeated violations, can lead to fines of up to 50,000 euros according to Section 60 LFGB. In severe cases or in the event of danger, a temporary ban on operations is also possible.

Hygiene officers carry out their internal controls using the 490 audit templates from the CIVAC workspace. Each inspection leaves an auditable trail with date, area, observation and corrective action. The appointment certificate, signed, filed, verifiable. This trace is just as valuable in the audit as the hygiene plan itself because it shows that the plan is actually being lived and does not just exist in the filing cabinet. It is precisely this gap between plan and practice that is the most common complaint from supervisors and the most common reason for overtime after unannounced inspections.

Hand hygiene requirements vary significantly depending on the industry. In nursing facilities, the WHO logic of five indications applies: before patient contact, before aseptic activities, after contact with body fluids, after patient contact and after contact with the patient environment. Hand disinfection is the rule here, hand washing is the exception when visibly dirty. Compliance monitoring is carried out by hygiene officers and hygiene specialists, whose function is specifically described in the state regulations on hospital hygiene. In nursing homes, home supervision supplements the density of controls.

In food processing, handwashing dominates before starting work, after every interruption, after going to the toilet, after breaks and after contact with raw food that can come into contact with ready-to-eat products. The IFS Food standard, version 8, requires a documented training matrix and visible marking of the washing areas. On construction sites, the requirements of the Construction Site Ordinance and DGUV Regulation 1 apply, supplemented by the requirements of the construction trade association for sanitary facilities. Mobile washing facilities with sufficient fresh water are a standard issue here that many construction management fail.

The regulatory requirements are lowest in administration, but the Federal Institute for Occupational Safety and Health (BAuA) recommends posting notices at all washing areas with DIN-compliant instructions. CIVAC supports industry-specific configurations in the workspace, so that care facilities, restaurants and industry receive different catalogues of duties without leaving the framework of the platform. The configuration is done once during setup and is automatically called up during the annual hygiene plan review so that industry-specific changes are not overlooked. If locations change their main activity, the configuration can be adjusted without losing historical evidence or archiving the old plan chain manually. This saves time when changing locations.

Frequent hand washing and disinfecting puts considerable strain on the skin barrier. Occupational dermatoses are recorded under number 5101 in the list of notifiable occupational diseases and are among the most common occupational diseases in Germany. In the healthcare sector, in cleaning and in food processing, hand eczema occurs in up to 30% of employees, which the professional association for health services documents in regular surveys. Hygiene officers must therefore not only keep hygiene in mind, but also skin protection and integrate it into the hygiene plan. Overlooked skin exposure not only leads to employee absence, but also to compliance breaches because employees shorten the steps to avoid pain.

A complete skin protection concept includes three components. Firstly, protect your skin before activity with suitable skin protection products, which should not be confused with skin care products. Secondly, skin cleansing with mild surfactants and without brushes, which mechanically damage the skin barrier. Thirdly, skin care after work with moisturizing preparations. The selection is made industry-specific and in coordination with the company doctor and the occupational safety specialist. The skin protection plan must be kept as a notice in the sanitary area and integrated into the instruction.

DGUV Information 250-010 describes the skin protection concept in detail and is the relevant technical reference. CIVAC integrates the skin protection concept into the hygiene plan and maintains it in the same workspace in which hand hygiene is also documented. The platform reminds us to review annually and adapt when changing areas of activity, so that employees with high skin exposure do not end up in standard configurations that do not meet their risk profile. Anyone who introduces skin monitoring early on will reduce sick leave rates and fluctuation in particularly stressful jobs in the long term.

The framed notice on the sink with the six steps of hand hygiene is the most visible measure, but rarely the most effective. It only works when it is embedded in a resilient organisation: appointed hygiene officer with an appointment certificate, written hygiene plan, annual training with receipts, regular checks with documentation and a reporting concept for outbreaks and abnormalities. These five elements form the minimum standard that supervisory authorities, health insurance companies and professional associations use to check. Anyone who cannot maintain one of the elements will be noticed in the audit, regardless of the quality of the remaining elements.

CIVAC is a compliance platform and officer-as-a-service with workspace, audit templates, appointment certificates, reporting lines and EU data residency. Licence the workspace for your internal representatives or have our representatives order it. Hygiene officers receive a preconfigured set for their industry, which contains all the building blocks from the appointment certificate to the hygiene plan to the training register. The auditor calls, the evidence is ready. The CIVAC SLA of 2 working days replaces the usual response window and closes the gap between theory and everyday operations. In replacement situations, the platform takes care of reminders and escalations without employees having to improvise.
