Confined spaces on cargo ships present unique challenges for workers, requiring careful navigation and adherence to strict safety protocols. These spaces, including boilers, pressure vessels, cargo holds, and void spaces, are characterized by restricted access, lack of windows for fresh air, and are not designed for continuous occupation. In this blog post, we will explore the importance of safety measures and equipment in these confined environments.

Understanding Confined Spaces

Confined spaces are defined by their limited access points and potential hazards such as low oxygen levels, toxic gases, or the risk of engulfment. On cargo ships, common examples of confined spaces include boilers, pressure vessels, cargo holds, ballast and fuel oil tanks, lubricating oil tanks, and void spaces. These areas require specialized safety measures to ensure the well-being of workers.

The Importance of Safety Gear

Safety gear is essential for workers operating in confined spaces on cargo ships. While preventative measures and management controls are prioritized over Personal Protective Equipment (PPE), certain situations may necessitate the use of PPE as a last resort. This includes scenarios where the environment poses immediate risks to health and safety, requiring immediate protection for workers.

Essential Equipment for Confined Spaces

Several pieces of safety equipment are crucial for workers operating in confined spaces on cargo ships:

  • Respiratory Protection Devices: This includes respirators or breathing apparatus to protect against hazardous atmospheres.
  • Gas Detectors and Monitors: These devices detect and monitor oxygen levels, combustible gases, and toxic vapors in confined spaces.
  • Harnesses and Fall Protection Gear: Essential for preventing falls and providing a means of rescue if a worker becomes incapacitated.
  • Communication Devices: Ensure workers can communicate effectively with each other and with supervisors outside the confined space.
  • Lighting Equipment: Provide adequate lighting in dark or poorly lit confined spaces.
  • Emergency Retrieval Systems: Enable swift and safe retrieval of workers in the event of an emergency.

PPE as a Last Resort

While PPE is generally considered a last resort in confined spaces, it may be necessary as the first line of defense for surveyors due to the dangerous nature of the environment and the relative isolation of individuals accessing the confined space. In such cases, appropriate PPE, such as protective clothing, gloves, and eye protection, must be provided to ensure worker safety.

Evaluating Risks and Selecting PPE

The selection of PPE for confined spaces must be based on a thorough evaluation of the specific risks and severity of risks in each confined area. Factors such as atmospheric conditions, potential hazards, and the duration of exposure should be considered when determining the appropriate PPE for workers.

Overarching Safety Principles

To ensure the safety of workers in confined spaces on cargo ships, several overarching safety principles should be followed:

  • Regular Training and Education: Ensure workers are adequately trained in confined space entry and rescue procedures.
  • Continuous Monitoring of Atmospheric Conditions: Regularly monitor and test atmospheric conditions in confined spaces to detect potential hazards.
  • Adequate Ventilation Systems: Provide sufficient ventilation to ensure a safe working environment in confined spaces.
  • Strict Adherence to Entry and Exit Procedures: Implement strict entry and exit procedures to minimize the risk of accidents and ensure the safe evacuation of workers in emergencies.


Safety measures and equipment are essential for navigating confined spaces safely on cargo ships. By prioritizing preventative measures, selecting appropriate safety gear, and adhering to strict safety protocols, workers can minimize the risks associated with confined space operations and ensure their well-being.
