What You'll Learn
Butyl alcohol is highly flammable
Butyl alcohol, also known as n-butyl alcohol, n-butanol, butyric alcohol, and 1-butanol, is a highly flammable clear liquid with a strong odour. It is a four-carbon, straight-chain alcohol that is highly volatile and easily evaporates at room temperature. Butyl alcohol has a very low flashpoint, which means it can easily ignite and cause a fire or explosion if not handled properly.
When handling butyl alcohol, it is crucial to take strict precautionary measures to ensure safety. All ignition sources, including smoking, flares, sparks, or open flames, must be eliminated from the immediate area. Any equipment used when handling butyl alcohol must be properly grounded to prevent any accidental sparks. In the event of a spill, it is important to prevent the liquid from coming into contact with the skin, eyes, or any open wounds. The spilled liquid should not be touched or walked upon, and the leak should be stopped if it can be done safely.
Due to its high flammability, butyl alcohol poses a significant fire hazard. If a fire occurs involving butyl alcohol, it is crucial to act quickly and efficiently. Small fires can be extinguished using dry chemical, CO2, water spray, or alcohol-resistant foam. However, it is important to note that water spray may not be effective in extinguishing fires involving butyl alcohol, especially in closed spaces. For larger fires, water spray, fog, or alcohol-resistant foam can be used. It is important to avoid aiming straight or solid streams directly onto the product to minimise the risk of spreading the fire.
In the event of a large spill or fire involving tanks, rail tank cars, or highway tanks, immediate evacuation is necessary. A safe distance of at least 800 meters (1/2 mile) should be maintained in all directions, and firefighting should be conducted from the maximum distance using unmanned master stream devices or monitor nozzles. Even after the fire appears to be out, containers should continue to be cooled with flooding quantities of water to prevent potential reignition. Additionally, it is crucial to be vigilant for any rising sound from venting safety devices or discolouration of tanks, as these could be indicators of a dangerous buildup of pressure or heat.
The highly flammable nature of butyl alcohol underscores the importance of safe handling and storage. It is crucial to follow established protocols and guidelines to minimise the risk of fires, explosions, and exposure to hazardous fumes. By taking the necessary precautions, individuals can protect themselves and their surroundings from the potential dangers associated with this highly flammable substance.

It can cause eye irritation
Butyl alcohol, also known as n-butanol, is a highly flammable clear liquid with a strong odour. It is a high-production-volume chemical with a range of industrial uses. It is also used as a gasoline additive or blend.
As a hazardous chemical, it can cause eye irritation. In fact, eye irritation is recognised as a hazard of n-butanol exposure. If butyl alcohol comes into contact with the eyes, it can cause serious irritation and potential damage. The eyes may experience corneal inflammation, blurred vision, and abnormal visual intolerance to light (photophobia).
To prevent eye irritation and potential damage, it is crucial to wear appropriate eye protection when working with butyl alcohol. This includes wearing safety goggles or a face shield to avoid direct contact with the eyes.
If exposure occurs, immediate action is necessary. The affected person should irrigate their eyes with large amounts of water, occasionally lifting the upper and lower eyelids to ensure thorough rinsing. This process should continue for at least 15 minutes or until medical assistance arrives.
In addition to eye irritation, butyl alcohol can also cause skin, nose, and throat irritation. It is essential to prevent skin contact and to immediately wash the skin if contamination occurs.
