SAFETY
on identifying gas presence at a specific location, requiring the gas to come into contact with the sensor to be detected. Such an approach is particularly effective in enclosed areas where gases are likely to gather. A leading solution in this field is the Dräger Polytron 8100 EC. This device is capable of identifying over 100 types of toxic gas and ensures continuous monitoring, even in extreme conditions such as high moisture levels and temperature fluctuations ranging from -40°C to +65°C. It comes with an integrated memory that stores all calibration and configuration data, allowing the sensor to be pre-calibrated and ready to use immediately upon installation. Fire detection represents a further
crucial layer of safety in maritime operations. The engine room, a critical area laden with continuous supplies of oxygen, heat, and fuel, is particularly susceptible to fire threats. This is because these elements collectively create ideal conditions for fires to ignite and propagate. Modern flame detection uses infrared sensors to identify hydrocarbon-based fires from a distance. For instance, the Dräger Flame 1500 (IR3) operates by
Exposure to ammonia can cause damage to the eyes, ears, nose, throat and lungs
measuring infrared radiation across three different wavelengths. These measurements are then compared to reference values of CO2, a byproduct of hydrocarbon combustion. This technology enables early detection of fires, thereby mitigating the potential for severe damage. While handling methanol and ammonia, proper PPE is another

necessary safety measure. During transport, refills or transfers, leaks or errors can lead to the escape of these toxic chemicals. That’s when respiratory protection can be life saving. Whether ammonia or methanol is the molecule in question will also determine if any further PPE is needed. Safety leaders recommend filtering devices like half masks with ammonia whereas methanol due to its characteristics might require independent air-supplying units.
INVOLVING EXPERTS As the shipping industry explores methanol, ammonia and also hydrogen as alternative fuels, the technology remains in its early stages, presenting numerous challenges that must be addressed to ensure a safe transition. Upcoming guidelines will provide a framework for integrating alternative fuels into the industry. However, it is crucial to consult with industry experts like Dräger who have experience with these chemicals and implement systems to detect them. Drawing on their insights will help
build a robust base of knowledge, guiding the industry on how to effectively retrofit existing vessels or design new ships that leverage these future-oriented fuel options.
