Final answer:
The correct labeling for a controlled product generally includes a work site label with the product identifier, hazardous properties, and safe handling instructions, and may also involve hazard symbols per the Globally Harmonized System.
Step-by-step explanation:
The question pertains to the labeling requirements for a 1-litre container of a controlled product intended for use by a single worker during a shift. While specific regulations can vary by region and country, typically, any container of a controlled or hazardous product used in the workplace should follow a standardized labeling system to ensure safety.
The labeling often includes critical information such as the product identifier, hazard statements, precautionary statements, and a reference to the Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS), which provides comprehensive information about the material, including the potential hazards and safety precautions.
Based on the options provided, the most appropriate option would usually be (c), a work site label containing 3 necessary elements. These elements typically consist of the product identifier, a list of the product's hazardous properties, and safe handling instructions.
Furthermore, a hazard communication standard like the Globally Harmonized System (GHS) might also require pictograms which include hazard symbols that visually depict the types of hazards present. It is essential in a laboratory setting to understand these regulations to maintain a safe working environment.
