What type of disposal method is used primarily for dangerous materials like sharps?

The correct choice for disposing of dangerous materials like sharps is steam sterilization. This method is effective in killing pathogens that may be present on the sharp objects, such as needles and blades, which pose a risk of needlestick injuries and infection transmission. Steam sterilization typically uses high-pressure steam to deactivate microorganisms and ensure that the materials are rendered safe for disposal.

This method is especially important in medical and laboratory settings, where ensuring the safety of personnel and the environment is critical. Steam sterilization is a preferred method in many healthcare facilities because it not only sterilizes but does so in an environmentally friendly manner. By using steam instead of chemicals, it minimizes the environmental impact often associated with chemical treatments or incineration.

In contrast, while incineration is another method that can be used to dispose of sharps, it is generally reserved for materials that cannot be effectively sterilized and require destruction. Chemical treatment and gelatinization methods also serve specific purposes but are not primarily aimed at the safe disposal of sharps.
