What must portable containers be labeled with when transferring hazardous chemicals?

When transferring hazardous chemicals into portable containers, it is crucial to label them with the specific chemical they contain. This is essential for several reasons:

1. Safety: Clear labeling helps ensure that anyone handling or coming into contact with the container can quickly identify its contents. This is critical in preventing accidents or exposure to harmful substances, as responders can take appropriate safety measures based on the identified chemical.

2. Compliance: Regulatory agencies, such as OSHA (Occupational Safety and Health Administration) in the U.S., require that containers used for hazardous materials are properly labeled. Adhering to these regulations helps maintain workplace safety standards and avoid legal repercussions.

3. Spillage or Leakage Response: In case of an emergency like a spill or leak, being able to quickly identify the chemical involved allows for the prompt implementation of the correct mitigation procedures.

While options regarding the date of transfer, a generic label, or no label might seem viable in certain contexts, they do not meet the fundamental requirement for ensuring immediate recognition of hazardous chemicals, which is critical for safety and compliance.
