A spillage of mercury has occurred that requires the use of the mercury spillage kit. Which one of the following options is the first action to be taken when dealing with the spillage?

When dealing with a spillage of mercury, the first action that should be taken is to apply personal protective equipment (PPE). This is crucial because mercury is a toxic substance that can pose serious health risks if it comes into contact with skin or is inhaled. By wearing appropriate PPE, such as gloves, eye protection, and a mask, you significantly reduce the risk of exposure to hazardous materials during the cleanup process.

Once the necessary protective measures are in place, you can safely proceed with other steps, such as applying absorbent paste or using specialized equipment. It’s essential to prioritize safety by ensuring that the person handling the spillage is adequately protected before taking further actions that may involve direct contact with the toxic material. This emphasis on safety is critical in dental environments where exposure to hazardous substances must be meticulously managed to protect both staff and patients.
