Ensuring Safe Air Quality in Medical Device Storage with ASPRA at XPO Logistics
Protecting Workers and Compliance: ASPRA L-C Air Purification for Carcinogenic Gas Removal
Medical devices disinfected with carcinogenic gases release harmful VOCs slowly throughout the supply chain, during transport and storage. With strict international regulations in place, maintaining safe air quality in warehouses is a critical challenge for logistics providers.
XPO Logistics, a global leader in supply chain management, implemented ASPRA L-C recirculation air purifiers from VFA Solutions to capture dust, pathogens, and harmful gases such as ethylene oxide (EtO). The result: EtO concentrations were reduced to less than 20% of the maximum allowable concentration (MAC), ensuring safe working conditions and regulatory compliance.
About the Project
Medical storage facilities face a unique challenge—many medical devices are disinfected using ethylene oxide (EtO), a carcinogenic gas that continues to release harmful VOCs into the air long after transport and storage. These emissions must be controlled to comply with strict international safety regulations and protect warehouse workers.
To address this, XPO Logistics partnered with VFA Solutions, implementing ASPRA L-C recirculation air purifiers. This modular and high-performance solution effectively removes particulate matter (PM), VOCs, pathogens, and gases, reducing EtO concentrations in the warehouse to just 0.1 ppm—well below regulatory limits. By ensuring clean and safe air, ASPRA technology enables XPO Logistics to operate in compliance with health and safety standards while protecting employees.

Detailed Approach
Problem Description
Medical devices disinfected with ethylene oxide (EtO) slowly release harmful gases into warehouse air throughout transport and storage. These emissions pose a severe health risk to employees and must be controlled to comply with strict global safety regulations.
Conventional ventilation methods often fail to effectively capture and remove fine particulate matter, pathogens, and VOCs, necessitating an advanced air purification solution that ensures both safety and compliance.
The Solution
XPO Logistics implemented ASPRA L-C recirculation air purifiers across its warehouses to provide a sustainable, high-performance air purification solution. The ASPRA system efficiently captured and removed VOCs, dust, and airborne pathogens, directly addressing the challenge of EtO emissions.
With modular and adaptable deployment, ASPRA L-C units were strategically placed to optimize air circulation, ensuring maximum gas capture and clean air throughout the facility while maintaining energy efficiency.
The Result
ASPRA L-C significantly reduced hazardous gas concentrations in the warehouse, achieving EtO levels of just 0.1 ppm, well below the maximum allowable concentration (MAC). This ensured regulatory compliance and provided employees with a safer and healthier working environment.
By eliminating the need for costly external degassing procedures, XPO Logistics also benefited from long-term operational cost savings while reinforcing its commitment to workplace safety and sustainability.
