Methanol Safety in Energy Transition
—Methanol is increasingly pivotal in sustainable mobility solutions, and innovations for the use of this clean energy alternative are being advanced. As methanol use grows, particularly to decarbonise the shipping industry, it's crucial to manage its significant safety risks effectively. Highly volatile and toxic, methanol demands rigorous safety measures to protect those who handle and use it.
With Dräger’s deep-rooted expertise in methanol safety, we stand as your trusted advisor in navigating methanol’s complexities. We deliver specialised safety solutions and expert advice, ensuring your operations are secure and aligned with sustainability goals.

Methanol Hazards
—Methanol liquid and vapours are extremely flammable.
Methanol is potentially explosive if vapour is released and it is in contact with an ignition source. Methanol is also water soluble.
The routes of exposure for Methanol include contact with the eye or skin, inhalation and ingestion.
Methanol vapour is heavier than air. It can accumulate in low lying areas and in confined spaces. It is very toxic to human health.
Toxicity
Methanol is toxic. It affects specific organs and the central nervous system, which can lead to long-term damage or death. Symptoms may include coughing, headache, dizziness, nausea, or blurred vision.
Flammability
Methanol is a highly flammable gas and can be ignited at concentrations between 6% by volume (LEL) and 50% by volume (LEL). Spontaneous ignition occurs at 440°C. At 9 °C, the flash point is relatively low. Above this temperature, vapours may form a flammable mixture with air.
Pale flame
Methanol burns with a barely visible bluish flame. Flame detectors are therefore necessary and provide early warning.
Propagation
Methanol is slightly denser than air (32 versus 28 grams per mole). The vapour often follows the movement of air. But if methanol is warmer than the surrounding air, it will rise. If it is cooler, it sinks and accumulates near the ground. Sensor positioning should, therefore, be individual, taking into account local conditions such as ventilation systems.
Skin resorption
Methanol is easily and quickly absorbed via all routes of exposure, including the skin. It spreads rapidly through the body and leads to symptoms of poisoning.
Hazards found in different application areas for Methanol
Recommended Plant & Personal Safety Solutions
—Due to the highly explosive and the toxic nature of Methanol, care needs to be taken when working in areas where it may be present. It is important where to take readings – as Methanol can be either lighter or in some situations, heavier than air.
Dräger has advantages with its IR detectors and the unique Dräger OV sensor for TOX- measurement offers significant advantages over the more expensive PID sensors.

Every industrial plant is different. From our extensive experience in the Methanol economy, we know that fixed fire and gas detection systems are only as effective as the planning which goes in to them. To that end, we work in close collaboration with our customers to provide guidance through the complete process – from consultation through design, realisation and implementation. So, you can achieve the best possible solution for your specific needs.
