Which item can be used to help dry a plaster cast safely?

Using a cool hair dryer is an effective way to help dry a plaster cast safely. Plaster casts are made from materials that can be sensitive to heat; applying direct heat, such as from a heat lamp or direct exposure to sunlight, can cause the plaster to dry too quickly or unevenly. This can lead to discomfort for the patient and potentially compromise the integrity of the cast itself.

A cool hair dryer, on the other hand, allows for a gentle flow of air that can help speed up the drying process without the risk of overheating. It permits control over the airflow and temperature, ensuring that the cast dries evenly while reducing the chances of skin irritation or damage to the cast.

Other methods, such as using a heat lamp or placing the cast in direct sunlight, are not advisable since they do not provide the same level of safety or control that the cool hair dryer offers.
