Marine/RV Detectors: What’s the Difference and Why are They Important?

Carbon monoxide (CO) detectors are crucial in any environment, but they are especially important in the marine and RV worlds. While houses typically have fewer CO sources and more space, boats and RVs are compact, enclosed areas often powered by gas or diesel engines and generators—all of which produce CO. Moreover, the proximity of boats and RVs to one another can lead to CO leaks from neighboring vehicles. If you spend time boating or RVing, it’s essential to understand the differences between smoke and CO detectors for these environments.

Key Differences Between Home and Marine/RV CO Detectors

1. Detection Levels Marine and RV CO detectors are designed to alarm at much lower CO levels than home detectors. According to Jim McAllister, OWL’s Marine Division, these detectors are labeled as “low-level” because they start to alarm at CO levels between 9-25 parts per million (ppm), depending on the brand. In contrast, home CO detectors typically alarm at levels between 70-100 ppm.

2. Power Source Home CO detectors usually operate on a 120-volt electrical system with a battery backup. On the other hand, marine and RV CO detectors primarily use batteries due to the limited electricity available on boats and RVs.

3. Environmental Durability Marine and RV CO detectors are often waterproof to withstand the conditions they are exposed to.

OWL advises equipping your recreational vehicles with the appropriate safety equipment, including marine/RV smoke detectors, fire extinguishers, and a first aid kit. Always review safety plans with your passengers before setting off on your trip, and most importantly, have fun!
