Which method is used to ensure that small holes in containers are temporarily sealed?

The method used to temporarily seal small holes in containers is patching and plugging. This technique involves using materials to cover the holes and prevent the escape of hazardous substances, thereby reducing the risk of spills or leaks during an incident. Patching typically includes the application of patch materials that can fill in and seal the hole, while plugging might involve inserting a solid or soft plug into the hole to stop any leakage.

Combining both methods provides a more robust solution to address small breaches in containers, making it a practical approach in HAZMAT situations where a quick and effective response is crucial. In contrast, while the terms patching, sealing, and isolation may relate to containing or addressing breaches, they do not capture the comprehensive approach required for effectively sealing small holes in containers as well as patching and plugging do.
