Hygiene standards for coats, hands and instruments
In short
Laboratory hygiene combines organised work, appropriate hand hygiene, suitable clothing and defined procedures for equipment and waste. Standards depend on activities and hazards. White clothing and gloves alone do not create a hygienic workflow.

Contents
Before starting
Know where personal possessions stay, which surfaces hold samples, where used instruments go and how waste is separated. Separate working materials, notes and personal objects to reduce transfer.
A simple plant class differs from microbiology, dissection or patient contact. Labels such as German S1 genetic-engineering level, biological protection level 1 and “sterile” are not interchangeable.
Clothing and gloves in the workflow
Wear work clothing only in its designated area and collect or store it appropriately afterwards. Do not mix clean and used garments casually. A contaminated coat is not suitable for home washing merely because a machine is available.
Choose and replace gloves correctly. Used gloves touching phones, bottles or handles can transfer contamination. Learn safe removal and follow the hand-hygiene plan afterwards.
Washing and disinfecting hands
They have different purposes. The activity determines which is required when. Follow application, contact-time and skin-protection instructions. Excessive unguided washing or switching agents arbitrarily can harm skin without improving control.
Instruments and surfaces
Place used tools where instructed without concealing sharps. Use approved cleaning and disinfection. Surface disinfection needs an appropriate agent, method and contact time; a quick improvised spray is not a dependable standard.
Checklist
Know instructions and controls; keep food, drinks and personal possessions away; secure long hair and follow jewellery rules; provide clean replacements and suitable sharps containers; wear gloves where appropriate; complete cleaning, waste and clothing procedures; report incidents immediately.
Read coat care, gloves and instrument care. The facility's hygiene plan governs the actual activity.
Questions
- Do all biological specimens require gloves?
- Not automatically. Risk assessment decides; unnecessary use can also cause mistakes and skin stress.
- Is a wiped case sterile?
- No. Cleaning, disinfection and sterilisation are different.
