When can a glass thermometer be used safely?

1. When it is stored at room temperature

2. When enclosed in a shatter-proof casing

3. When used to measure food in a pan

4. When it is calibrated correctly

The correct answer is: When enclosed in a shatter-proof casing

A glass thermometer can be used safely when it is enclosed in a shatter-proof casing. This type of casing protects the glass from breaking, which not only prevents potential injury but also avoids contamination from any glass shards that might mix with food if the thermometer were to break. This safety feature facilitates using the thermometer in environments where it might be subjected to dropping or significant impact, such as in a busy kitchen. While calibration is essential for accurate readings, the primary concern is ensuring the thermometer can be used without risk of breakage. Storing a glass thermometer at room temperature does not reduce the risk associated with its use, and measuring food in a pan could lead to accidents if the thermometer isn't protected, especially if the pan is moved or bumped during food preparation. Thus, the safety of using a glass thermometer is significantly enhanced when it is kept within a shatter-proof casing.
