Under what condition is sampling of hazardous cargo required to be performed?

Sampling of hazardous cargo is required to be performed when it is safe to do so. This criterion ensures that personnel can conduct the sampling without jeopardizing their safety or risking further incidents. Safety considerations include stable weather conditions, proper handling procedures, and the absence of immediate hazards.

Choosing a safe moment for sampling allows for the assessment of the cargo's properties while minimizing exposure to potential risks associated with the hazardous materials. This aligns with safety protocols and regulatory requirements aimed at protecting workers and the environment.

In contrast, sampling should not be conducted solely based on calm weather conditions or restricted to situations where accidents occur, as these do not encompass the broader safety requirements involved in handling hazardous materials. Additionally, undertaking such tasks without any specific requirements would disregard necessary regulations and safety measures crucial in handling potentially dangerous substances.
