Which type of mine requires at least one full-time safety engineer?

The requirement for a mine to have at least one full-time safety engineer is specifically outlined in regulations for Class A mines. These mines are typically characterized by their size, complexity, and the potential hazards involved in their operation. The presence of a full-time safety engineer is crucial in Class A mines because it ensures that there is dedicated oversight and management of safety practices and procedures. This role is vital for assessing risks, implementing safety measures, conducting safety training, and responding to incidents effectively, all of which contribute to safeguarding the health and safety of the workforce.

In contrast, Class B and Class C mines often have different regulatory requirements that might not mandate the presence of a full-time safety engineer. Although safety is still a critical concern in these mines, the specific complexities and hazards present in Class A mines necessitate more rigorous oversight, justifying the requirement for a dedicated safety engineer. Open-pit mines, while they also have significant safety considerations, may not fall under the same classification system as underground mines and therefore do not directly correlate with the requirement for a full-time safety engineer in the way that Class A mines do.
