Medical Laboratory Safety

ISO 15190 is the international standard for safety in the medical laboratory. Where ISO 15189 addresses the quality and competence of the testing a lab performs, ISO 15190 addresses a different question: whether the people who work in that lab, and everyone around them, are protected from the very real hazards of handling human samples, chemicals, biological agents and laboratory equipment. It sets out the requirements for a laboratory to establish and maintain a safe working environment.

It is best understood as the safety companion to ISO 15189. Most laboratories do not pursue ISO 15190 in isolation; they implement it alongside their ISO 15189 quality system so that competence and safety are managed together. In practice, laboratories conform to and implement ISO 15190 as part of their overall management system rather than holding it as a standalone certificate — the point is demonstrable, day-to-day safety, not a plaque on the wall.

The standard covers the full range of laboratory hazards: biological (infectious samples and cultures), chemical (reagents, solvents, fixatives), physical (sharps, glass, electrical, ergonomic), and fire and emergency risks. It defines management responsibilities, safety roles, training, personal protective equipment, waste handling and emergency preparedness — the machinery a lab needs to keep its staff and visitors safe.

ISO 15190 is written for any laboratory that handles samples from the human body and the hazards that come with them. That includes:

• Hospital and clinical pathology laboratories — chemistry, hematology, microbiology, immunology and related disciplines.
• Private and reference diagnostic laboratories processing high volumes of potentially infectious material.
• Microbiology and molecular laboratories working with cultures, pathogens and reagents that carry biological or chemical risk.
• Histopathology and cytology laboratories using fixatives, solvents and sharps.
• Blood banks and transfusion services.
• Public health and specialist laboratories where staff exposure must be actively managed.

Laboratories adopt ISO 15190 because safety is inseparable from good practice — and because health systems, regulators, insurers and their own staff increasingly expect it. It is most often implemented by labs already pursuing or holding ISO 15189 accreditation, since assessors and health authorities look closely at how a lab protects its people. If your laboratory exposes staff to biological, chemical or physical hazards, ISO 15190 gives you a recognized framework for managing that exposure rather than relying on informal habits.

The standard sets out what a laboratory must have in place to manage safety systematically. The main themes are:

• Management commitment and a defined safety structure — clear responsibility for safety, including a designated safety officer or equivalent role.
• Risk assessment of biological, chemical, physical and other hazards, with controls chosen to match the level of risk.
• A documented safety program and safety manual that staff can actually find and follow.
• Personnel safety training and competence — induction, ongoing training and records that show staff understand the hazards they work with.
• Personal protective equipment — selection, provision, use and maintenance appropriate to the work.
• Handling of biological hazards — safe practices for infectious material, containment and decontamination.
• Chemical safety — storage, labeling, safety data and controls for hazardous substances.
• Waste management — safe segregation, handling and disposal of biological, chemical and sharps waste.
• Emergency preparedness — response to spills, exposures, fire and first aid, with the equipment and procedures to match.
• Incident and accident reporting and investigation, feeding into corrective action and continual improvement.

What sets ISO 15190 apart from generic workplace-safety guidance is that it is written for the specific hazards of a medical laboratory and dovetails with the ISO 15189 quality system, so safety and competence reinforce each other rather than living in separate binders.

The first reason is the most human one: protecting your staff. Medical laboratories expose people to infectious samples, hazardous chemicals and sharps every day. A structured safety program built to ISO 15190 reduces the exposures, needlestick injuries and spills that cause real harm — and the downstream cost of lost time, investigations and staff turnover.

Implementing ISO 15190 also strengthens your ISO 15189 position. Accreditation assessors and health authorities pay close attention to how a laboratory manages safety, and a mature safety program removes a common source of findings. It signals to regulators, insurers and prospective staff that your laboratory takes its duty of care seriously.

Operationally, the discipline pays off. Clear roles, proper training, correct PPE and rehearsed emergency response mean fewer incidents and faster, calmer handling when something does go wrong. Above all, it turns safety from a set of informal habits — which vary from shift to shift — into a managed system that holds up under pressure and scrutiny.

With 30+ years of building management systems and 900+ organizations guided to certification and accreditation at a 100% first-time pass rate, we know how to build a safety program that works on the bench, not just on paper — and one that sits cleanly alongside your ISO 15189 quality system.

Our 10-Step Approach takes you from a safety gap assessment through hazard risk assessment, documentation, staff training, internal audit and management review. Because most laboratories run ISO 15190 together with ISO 15189, we integrate the two so you have one coherent management system rather than two competing sets of paperwork. We write your safety documentation as single-level documentation, typically under 200 pages, mapped to your real workflows — short enough that bench staff actually read and follow it.

Most ISO 15190 programs run on a typical 6-9 month timeline, depending on the size of your laboratory, the range of hazards you handle, the number of disciplines and sites, and how mature your existing safety practices already are. We focus on the things that matter most in a lab: clear safety responsibility, honest hazard assessment, real training records and emergency readiness you can demonstrate.

• Treating safety as separate from quality. Running ISO 15190 in a silo away from ISO 15189 creates duplicate paperwork; we integrate them into one system.
• Generic risk assessments. Copy-paste hazard assessments that do not reflect the actual biological and chemical risks on your bench.
• Thin training evidence. Having a safety manual but no records showing staff were trained and understood it.
• PPE gaps. Providing equipment without clear guidance on selection, use and maintenance for each task.
• Weak waste and spill controls. Unclear segregation, handling or disposal of biological, chemical and sharps waste.
• Unrehearsed emergency response. Procedures that exist on paper but have never been practiced for spills, exposures or fire.
• Poor incident follow-through. Reporting accidents but never investigating or acting on them.
• Over-documentation. Multi-level manuals nobody reads; we keep it single-level and usable so safety stays live.
