Uses: Sulfuric acid is an important basic chemical raw material, mainly used in the chemical fertilizer industry, and is widely used in medicine, metallurgy, organic synthesis, rubber, chemical fiber, paint, petrochemical, national defense and other industries.
Packaging: special tanker (boat), porcelain altar or other acid-resistant container.
Operating instructions: Sulfuric acid is a strong acid, which is corrosive and dehydrating. Wear protective equipment when operating. The working site should be provided with an emergency water source. Once burned by sulfuric acid, it can be washed with a lot of water and treated for medical treatment. Sulfuric acid storage, transportation, and use should strictly abide by the fire safety and dangerous goods safety regulations. Sulfuric acid should avoid contact with organic matter, metal powder, etc. When transporting by tanker (ship), it is forbidden to smoke or use open flames near open containers.
