EN ISO 23907 Protection against Cutting Tool Injuries - Requirements and Test Methods

The “EN ISO 23907 Protection against sharp instrument injuries - Requirements and test methods” standard, developed by the International Organization for Standardization (ISO) and later published as a European standard within the scope of harmonization efforts, consists of the following sub-sections published under the same title:

• The standard “EN ISO 23907-1 Part 1: Disposable sharps containers” describes the requirements for disposable sharps containers designed to contain potentially hazardous sharps medical waste, such as scalpel blades, trocars, hypodermic needles, and syringes, with or without sharps protection features. This standard applies to disposable sharps containers supplied complete by the manufacturer and to containers supplied in components for assembly by the user.

Sharps containers (sharps boxes or puncture-resistant containers) are essential for the safe disposal of potentially hazardous medical sharps waste. These include hypodermic needles, syringes, scalpel blades, trocars, and other sharp medical instruments that can cause needle stick injuries, infections, or exposure to bloodborne pathogens.

This standard specifically targets disposable (single-use) sharps containers to minimize the risk of sharps injury during use, handling, and disposal. It specifies minimum requirements and standardized test methods to ensure these containers provide reliable protection against puncture, leakage, and accidental access to contents.

This standard does not apply to:

• Reusable cutting tool containers
• External transport containers for full disposable containers.

This standard applies to disposable sharps containers supplied by the manufacturer as complete units or as user-assembled components. These containers are designed to safely contain sharps medical waste, with or without additional sharps protection features (e.g., needle guards or retractable mechanisms in the devices themselves).

The primary goal is to prevent cuts by ensuring the container has the following properties:

• It should resist penetration by sharp objects.
• Prevents content leakage.
• Enables safe, one-handed disposal of the cutting tool without manual manipulation.
• It includes features such as secure shutdown and clear labeling.

This standard includes performance criteria and mandatory tests, including the following:

• Penetration resistance: The container walls and lid must withstand forces from simulated cutting tools without being punctured.
• Impact resistance: The ability to withstand drops and impacts without opening or revealing the contents.
• Leak prevention: Prevents leakage of liquid contents under specified conditions.
• Accessibility and tamper resistance: The design must allow for easy (usually one-handed) placement of cutting tools while preventing manual entry or unauthorized access.
• Handles and stability: Carrying handles (if any) and stability requirements to prevent tipping.
• Marking and labeling: Clear instructions, warnings (e.g., biological hazard symbols), capacity indicators, and manufacturer information.
• Assembly and usability: Instructions and tests for user-assembled systems ensure correct operation.

These tests simulate real-world health scenarios to verify safety and reliability.

Sharps injuries remain a serious occupational hazard for healthcare workers, laboratory personnel, and waste handlers. Compliance with the EN ISO 23907-1 standard helps reduce these risks and supports regulatory compliance in many countries.

This standard plays a vital role in promoting safer medical waste management globally.

• The standard “EN ISO 23907-2 Part 2: Reusable sharps containers” describes the requirements for reusable sharps containers designed to contain potentially hazardous sharps medical waste, such as scalpel blades, trocars, hypodermic needles, and syringes, with or without sharps protection features. This standard applies to sharps containers supplied complete by the manufacturer and those supplied in components for user assembly. It does not apply to single-use sharps containers (for such containers, the EN ISO 23907-1 standard applies).

This standard includes design functionality for user safety, lifecycle simulation, cleaning and decontamination, microbiological validation, quality monitoring, and performance testing.

In the design process of cutting instrument containers, risk assessment principles and human factors must be considered to prevent improper use such as incorrect assembly and overfilling. The ISO 14971 standard applies when containers are classified as medical devices. Unless local regulations specify otherwise, the dominant base color should be yellow. Visibility of the fill level should be a design requirement for the containers. When evaluated according to this standard, the container should not show any rupture, leakage, or deterioration that could negatively affect its safe use or functionality.

In healthcare settings, sharp instruments (such as needles, scalpels, knives, and other sharp medical tools) pose a significant risk of injury and infection transmission to healthcare workers, patients, and waste handlers. Proper storage of these sharp instruments is crucial to prevent sharp instrument injuries that can lead to exposure to bloodborne pathogens such as hepatitis B, hepatitis C, and HIV.

The EN ISO 23907-2 standard contains detailed requirements and test methods for reusable sharps containers designed to safely contain potentially hazardous medical sharps waste.

Unlike single-use containers (EN ISO 23907-1), reusable versions are designed for multiple cycles: collection, safe transport, professional cleaning/disinfection, revalidation, and reuse. This standard ensures that these containers maintain their safety and performance throughout their lifecycle.

The main objectives are as follows:

• Minimizing the risk of sharp objects falling out, spilling, or accidentally being accessed.
• To prevent injuries from sharp objects during use, closing, transport, and handling.
• To ensure the container remains effective even after repeated cleaning and disinfection processes.

This standard includes, but is not limited to, mandatory performance criteria and test protocols:

• Physical strength and endurance: Resistance to impact, puncture, drops, and pressure tests.
• Sharp object protection: Design features such as limited openings, tamper-resistant locks, and mechanisms to prevent overfilling or access via pinpointing.
• Sealing and closure: Secure final closure that cannot be easily reopened without tools or damage.
• Leak resistance: Even when filled with liquid or inverted.
• Reusability features: Verified that cleaning, disinfection, and sterilization processes do not degrade performance (material integrity, functionality after multiple cycles).
• Marking and labeling: Clear instructions for use, maximum fill line, reuse indicators, manufacturer information, and conformity marking.
• Color coding and symbols: Consistent with international conventions for biological hazardous waste.

The EN ISO 23907-2 standard defines rigorous, repeatable testing procedures (typically mechanical, environmental, and simulated use tests) to verify conformity. Examples include:

• Drop tests from specified heights.
• Puncture resistance with standardized needles or forces.
• Impact and stacking tests.
• Simulated overfilling and inversion tests.
• Accelerated aging and repeated cleaning cycles to simulate the real-world life cycle.

Manufacturers must demonstrate compliance through independent testing, and many consider EN ISO 23907-2 to be the gold standard for reusable cutting tool containers for healthcare waste management.

• The standard “EN ISO 23907-3 Part 3: Containers for the safe storage of sharps and medical waste” focuses on sharps containers designed for the safe storage and disposal of sharps and medical waste that is safely contained and disposed of. Safe sharps generally refers to sharps (such as needles, knives, syringes, trocars, or other items that carry a risk of puncture) whose injury-preventing features are already activated or otherwise made safe (e.g., by retractable mechanisms, caps, or blunting).

This standard includes:

• Requirements for the design, construction, and performance of these vessels.
• Suggestions for improving security, usability, and effectiveness.
• Test methods to verify compliance ensure that containers prevent accidental access to contents, resist punctures, leaks, and unauthorized opening, and maintain their integrity during handling, transport, and final disposal.

This standard applies only to containers designed for already secured cutting tools (not for unsecured or unprotected cutting tools). This distinguishes it from previous or related standards covering general or disposable cutting tool containers.

Cutting tool waste containers that comply with this standard help to:

• It minimizes the risk of sharps injuries during waste processing and transportation.
• It ensures compliance with safe disposal protocols in hospitals, clinics, laboratories, and other medical facilities.
• It meets regulatory and best practice expectations in many countries.

Manufacturers must demonstrate compliance through rigorous testing (e.g., drop tests, penetration resistance, leakage, and functional performance under simulated operating conditions).
