What are the approved types of aspirators mentioned?

The correct choice highlights the range of acceptable aspirators utilized in the context of funeral services. In Missouri, regulations and standards for aspirators, which are essential for fluid removal during embalming, specify that both electric and water-operated models are permissible, as well as water-controlled systems.

This inclusion reflects the need for flexibility in choosing equipment that can meet diverse operational requirements. Electric aspirators provide efficiency and ease of use, while water-operated systems can be advantageous in certain situations, such as during power outages or in locations where electricity may be limited. Water-controlled aspirators also contribute to this versatility, offering an alternative method that can be ideal depending on the embalmer's preference and the specific circumstances of each case.

Recognizing this variety allows funeral professionals to select the most suitable aspirator, ensuring compliance with legal standards while also providing effective care for the deceased. The other options, which limit the types of aspirators to just one type, do not reflect the comprehensive approach that Missouri law endorses.
