Chemical of the Quarter: Understanding Methyl Alcohol

Methyl alcohol has the simplest chemical structure of all alcohols. It is toxic if ingested, inhaled, or when it comes into contact with skin or eyes. In addition, methanol (as it is more commonly known) is highly flammable in both the liquid and vapor states. With the increased desire to use alternative fuels that reduce or eliminate greenhouse gases, the International Maritime Organization (IMO) approved methyl alcohol as an alternative maritime fuel in 2020. Ship builders have started designing vessels that not only transport methyl alcohol, but also use it as a fuel, which can significantly reduce the amount of greenhouse gas emissions compared to conventional fuels. There is no current regulation regarding methyl alcohol as a safe alternative fuel for U.S. vessels, meaning the Office of Design and Engineering Standards approves the use of methyl alcohol for this purpose on a case-by-case basis. The Marine Safety Center ensures that vessel plans comply with regulations ensuring toxic and hazardous cargoes are transported in a safe manner.
