The Dangerous Cargo of Merchant Ships in the Late 19th Century: Explosive Fertilizers and Their Hazards

Merchant ships of the late 19th century carried a variety of goods across the seas, some of which were essential for agriculture but also posed significant risks to the safety of the crew. Among these risks, one type of cargo, which may seem perplexing today, was considered particularly dangerous: original organic fertilizer, specifically manure from cows, sheep, and other farm animals.

Origins of Organic Fertilizer in the Pre-Chemical Fertilizer Era

Before the advent of commercial chemical fertilizers, animal manure was the primary source of fertilizer for farms. This organic material was essential for soil health and plant growth. Be it cow poop, sheep manure, or dung from other livestock, manure provided essential nutrients that plants required. Even today, in some parts of the world, animal manure is still used as a form of fertilizer.

Complications with Organic Fertilizer Transport

The process of transporting manure by ship was fraught with challenges. As the manure decomposed, it produced gases such as methane and ammonia. Moreover, if the manure became wet, most commonly from exposure to salty seawater, it could lose its utility as a fertilizer. The introduction of moisture would lead to the release of hazardous gases, some of which could be explosive in nature.

Shipping Labels and Special Precautions

To mitigate the risks associated with transporting these potentially explosive goods, the containers used to store manure on ships were marked with a label that read “SHIP HIGH IN TRANSIT.” This label is an intriguing anachronism that brings to mind the struggles of maritime safety centuries ago. The phrase can be interpreted as a play on words, where “SHIP” becomes synonymous with “SHIT,” emphasizing the hazardous nature of the cargo.

The importance of keeping the manure dry cannot be overstated. Any moisture could lead to gas buildup, and in extreme cases, these gases could become explosive. To ensure the safety of the ship and its crew, the manure was often stacked on top of other cargo, where it would be less likely to come into contact with seawater.

Ensuring Safety: A Humorous Twist

The practice of shipping explosive fertilizers highlights the challenges of 19th-century maritime trade and the ingenuity required to ensure safety. The situation, while not without its comedic undertones, underscores the importance of safety regulations in shipping.

The term “SHIP HIGH IN TRANSIT” remains an enigmatic part of maritime history, its dual meaning serving as a reminder of the sometimes humorous and serious nature of early industrial commerce.

Conclusion

The story of how merchant ships handled potentially explosive organic fertilizers in the late 19th century is a fascinating tale of innovation, risk, and safety measures. While the idea of transporting manure that could explode may seem absurd to us now, it provides valuable insights into the challenges and practices of maritime trade during that time.
