OPLS at the naval port in Gdynia. Polish Navy enhances CBRN contamination mitigation procedures

Advanced chemical, biological, and radiological (CBRN) contamination mitigation exercises were conducted at the naval port in Gdynia. The joint operation, involving chemical specialists from the 43rd Sappers Battalion and the crew of ORP Ślązak, aimed to refine threat identification protocols and enhance decontamination procedures aboard Polish Navy vessels.

The onboard contamination mitigation station (OPLS) is a key component of the navy’s defense system against CBRN threats. Its primary mission is the rapid detection of hazardous contamination, followed by effective decontamination, ensuring the vessel’s swift return to operational readiness.

The exercise encompassed a full decontamination cycle, including contamination identification, safety zone designation, and the application of specialized neutralizing agents. Regular training of this nature plays a crucial role in maintaining the operational readiness of naval units and ensuring the safety of their crews.

What is CBRN and what threats does it cover?

CBRN stands for chemical, biological, radiological, and nuclear threats. This term refers to hazardous substances and situations that pose serious risks to people, the environment, and infrastructure.

Types of CBRN threats:

C (chemical) – Chemical substances, including chemical warfare agents (e.g., sarin, mustard gas) and toxic industrial chemicals.
B (biological) – Biological warfare agents, pathogens (e.g., viruses, bacteria, toxins) capable of causing epidemics.
R (radiological) – Radioactive materials, radiation contamination from accidents or terrorist attacks.
N (nuclear) – Nuclear explosions, reactor failures, and fallout effects.

Armed forces, emergency response teams, and specialized military units (e.g., military chemists) train to identify, neutralize, and protect against such threats.

The continuous improvement of contamination mitigation procedures aligns with NATO’s strategy for enhancing the operational resilience of naval forces. Cooperation between specialized military units and the integration of modern CBRN protection technologies form the foundation of effective defense against chemical, biological, and radiological hazards.
