Safe handling

Methanol is used safely around the world every day across a wide range of industries. Like any fuel or chemical product, it must be handled responsibly and with appropriate safety measures in place. With the right training, procedures, and equipment, methanol can be stored, transported, and used safely.

Methanol must be stored in tanks built from materials that are compatible with methanol service. Carbon steel is widely used and performs well with methanol, while some metals, seals, and rubber materials may not be suitable for long-term contact with methanol.

Storage tanks are typically designed to prevent the formation of flammable vapors. In larger industrial applications, this may include the use of nitrogen blanketing, which helps keep air out of the vapor space above the liquid surface. Tanks should also be equipped with pressure relief valves, flame arrestors on vent lines, and fixed vapor detection in surrounding areas. Secondary containment measures, such as bunds or drip trays, are commonly used to help contain leaks or spills and prevent methanol from reaching surrounding areas.

As with other flammable fuels, storage areas should be clearly marked and kept free from potential ignition sources, including open flames, hot work, and unsuitable electrical equipment.

Methanol has been transported safely around the world for decades as both a chemical product and a fuel. Today, it is moved globally by sea, road, and rail using established infrastructure and internationally recognised safety standards.

For international shipping, methanol transport must comply with the International Maritime Dangerous Goods Code, which classifies methanol as a Class 3 flammable liquid and sets requirements for packaging, labelling, documentation, stowage, and segregation from incompatible cargoes.

Road transport is regulated through frameworks such as the European Agreement concerning the International Carriage of Dangerous Goods by Road (ADR) and equivalent national regulations.

Additional safety measures are used when methanol is transferred between storage facilities, vehicles, vessels, or bunkering systems. Depending on the application, these may include gas detection systems, emergency shutdown procedures, and specially designed transfer equipment to help prevent leaks and reduce fire risks.

In the maritime sector, methanol-fueled vessels and bunkering facilities operate under dedicated safety guidelines and standards developed specifically for methanol as a marine fuel. Emergency shutdown systems must be tested regularly and before any bunkering operation.

The protective equipment required when handling methanol depends on the task being performed and the potential for exposure. At minimum, workers should use appropriate chemical-resistant gloves and eye protection when there is risk of contact with methanol.

In situations where vapor exposure is possible, respiratory protection is also required.

For higher risk activities, such as bunkering operations and maintenance work, additional protective equipment is necessary, including full chemical-resistant suits with integrated hood and boots.

Protective equipment is the last line of defence, not the first. It is most effective when combined with well-designed systems, clearly documented procedures, and personnel who are trained in methanol safety and emergency response.
