    This symbol should be present on the label of industrial cleaners containing sodium hydroxide because sodium hydroxide is a highly corrosive base. The symbol represents the potential danger of the substance causing corrosion, which can result in damage to surfaces, materials, and even skin upon contact. It serves as a warning to users to handle the product with caution and take necessary safety measures to avoid any harm or damage.

    The fact that most aerosol cans have propellants that can be ignited easily means that this symbol should be on their labels. Since it poses such a fire hazard a bottle of methanol would have this symbol on it's label. - ProProfs

    The fact that most aerosol cans have propellants that can be ignited easily means that this symbol should be on their labels. Since it poses such a fire hazard a bottle of methanol would have this symbol on it's label.

    Explanation
    The correct answer is "flammable" or "flammable material" because both aerosol cans with easily ignitable propellants and a bottle of methanol pose a fire hazard. The presence of this symbol on their labels serves as a warning to users about the potential flammability of these substances.

    By releasing oxygen, can cause a flammable material to burn more easily. - ProProfs

    By releasing oxygen, can cause a flammable material to burn more easily.

    Explanation
    Oxidizing refers to a process or substance that releases oxygen. When an oxidizing material is present, it can react with other substances and provide oxygen to support combustion. This means that if a flammable material is exposed to an oxidizing material, it can burn more easily as it has an additional source of oxygen to fuel the fire.

    Chemicals in this division are classified as toxic because they can cause harmful effects, such as birth defects in children or liver damage. The term "toxic material" is used to further emphasize the potential harm these chemicals can cause. Additionally, the phrase "toxic with long term effects" indicates that prolonged and repeated exposure to these chemicals can lead to the development of cancer.

    Blood samples that have been contaminated by Hepatitis B viruses should be tagged with this symbol. - ProProfs

    Blood samples that have been contaminated by Hepatitis B viruses should be tagged with this symbol.

    Explanation
    Blood samples that have been contaminated by Hepatitis B viruses should be tagged with the symbol "biohazard" or "biohazardous material" because these symbols indicate the presence of a biological hazard or potential danger to human health. The Hepatitis B virus is a bloodborne pathogen that can cause serious liver infection and is highly contagious. Therefore, labeling the contaminated blood samples with the biohazard symbol helps to ensure proper handling, disposal, and protection of individuals who come into contact with the samples.
