Introduction
The latest update from the European Agency for Safety and Health at Work (EU OSHA) highlights a significant shift in workplace safety, particularly for healthcare workers who handle Hazardous Medicinal Products (HMPs).1
This update stems from the most recent changes to Directive 2004/37/EC, which now incorporates reprotoxic substances and features an indicative list of HMPs.2 These developments aim to increase worker safety, particularly for healthcare professionals prone to exposure from preparation and administration of HMPs.
A Brief Background
Understanding Directive 2004/37/EC
Directive 2004/37/EC, commonly referred to as the Carcinogens, Mutagens, and Reprotoxic substances Directive (CMRD), is a key piece of legislation aimed at protecting workers from exposure to hazardous substances.
Initially, it addressed carcinogens and mutagens, ensuring worker safety from risks such as cancer and genetic anomalies. Through amendments, most notably Directive 2022/431/EU, the scope has widened to cover reprotoxic substances—agents harmful to human reproduction.
The significance of this expansion can’t be understated, as it includes many hazardous medicinal products, making this legislation more responsive to the risks encountered by healthcare and related sectors.
The Importance of the Recent Update
The EU Commission’s latest OSHA update establishes an indicative list of HMPs to assist employers in identifying potential hazards. This list couples with enhanced guidelines that stress replacing harmful substances wherever possible or relying on tools, such as closed systems and CSTDs, to minimize exposure.
Key Changes in the Update
The most noteworthy alterations include the following:
/ Addition of Reprotoxic Substances
Reprotoxic substances are now fully recognized under the CMR framework. This step amplifies protection for workers handling substances linked to fertility issues, birth defects, or developmental disorders.
/ Indicative List of Hazardous Medicinal Products
For the first time, there’s an EU-endorsed indicative list of HMPs. This includes antineoplastics, immunosuppressants, and antiviral medicines, among others. These drugs, while vital for treating patients, present risks to healthcare workers due to their classification as Category 1A or 1B carcinogens, mutagens, or reprotoxic agents.
This list offers clarity for employers performing risk assessments and deciding on safety measures.
/ Expanded Employer Obligations
Employers are now mandated to introduce robust safety protocols. This includes offering regular worker training, conducting detailed risk assessments, substituting hazardous substances where feasible, and using closed systems to prevent exposure.

Employer Responsibilities
Under these updated guidelines, employers are required to adopt a proactive approach to minimize workplace hazards. Here’s a breakdown of what’s expected:
1. Comprehensive Risk Assessment
Employers must evaluate all possible exposure routes—dermal, respiratory, and oral—when handling HMPs. Data must be renewed regularly and made available to authorities upon request.
2. Implementation of Closed Systems
Where substitution isn’t possible, a closed technological system must be employed. Closed System Transfer Devices (CSTDs), like those offered by EQUASHIELD®, play a important role here, preventing exposure and minimizing contamination.
3. Worker Training and Information
Employers must ensure all workers handling HMPs receive regular training. This includes understanding potential risks, proper handling protocols, and how to react in case of exposure incidents.
4. Hygiene and Safeguards
Worker safety goes beyond prevention—employers are required to provide protective clothing, hygiene facilities, and regular health surveillance to detect early signs of exposure-related conditions.

Impact on Healthcare Workers
A Healthier Workplace for Medical Professionals
These updates are set to transform how healthcare workers like pharmacists, oncology nurses, and pharmacy technicians handle cytotoxic medications. With exposure linked to serious health risks—including cancer, miscarriages, and respiratory issues—the provision of safer environments is long overdue.
For example, studies reveal nurses handling cytotoxic drugs are three times more likely to develop malignancies compared to those not exposed.3 The new OSHA recommendations emphasize protective measures to reduce these distressing statistics.
Safety with CSTDs
In the life cycle of HMPs from manufacture to disposal, as set out in the European Commission Guidance for the Safe Management of HMPs at work 2023, a closed system in healthcare means the use of biological safety cabinets (BSCs), containment isolators and closed system transfer devices (CSTDs). Isolators and BSCs are effective in preventing contamination and occupational exposure in the preparation of HMPs in the pharmacy, whilst CSTDs are effective across the whole life cycle of HMPs and in particular in the administration of HMPs on the wards.
EQUASHIELD® CSTDs offer industry-leading solutions. With features like a closed-back syringe plunger and leak-proof design, these devices minimize contamination better than other alternatives.4
Complementary Solutions and Prevention
When discussing protective measures, CSTDs are just the beginning. Employers and healthcare facilities can also reduce exposure risks by leveraging pharmacy automation systems.
The Role of Automation in HMP Handling
Advanced technologies like EQUASHIELD® Mundus Mini HD automate processes, reducing manual manipulation and potential exposure points. Robots and automated systems ensure precision, decrease errors, and boost staff safety.
Cross-sector Applications
Beyond healthcare, these updates emphasize protective measures in waste disposal, veterinary care, and even hospital cleaning staff working with contaminated linens or equipment.
By using a combination of CSTDs, automation, and routine safety training, all industries involved in HMP handling can meet OSHA’s directives while fostering safe working conditions.
Taking Action for Safer Workplaces
Employers, healthcare professionals, and safety managers must align their practices with these updated OSHA regulations.
If you’re unsure where to start, EQUASHIELD®’s EQ Academy offers incredible resources—including tutorials and webinars—on safe HMP handling practices. Their closed system transfer devices and pharmacy automation solutions are trusted by industry leaders to meet the highest safety standards.
Consider the following actionable steps to ensure compliance and protect workers handling HMPs:
/ Perform an updated risk assessment for all hazardous materials.
/ Transition to closed systems like EQUASHIELD® CSTDs.
/ Train all relevant staff using OSHA-aligned education programs.
/ Explore automation solutions to further minimize handling risks.

Safeguarding the Future for Healthcare Workers
The EU OSHA update represents a fundamental step forward in protecting workers from the risks posed by Hazardous Medicinal Products. By emphasizing preventative systems like CSTDs and prioritizing worker well-being, employers can create safer, more efficient work environments.
Businesses have a responsibility to not only meet these updated standards but also to safeguard their teams and reduce the long-term impacts of exposure. With comprehensive strategies and advanced solutions like those from EQUASHIELD®, compliance is not just achievable—it’s a path to a healthier workforce.
