Step-by-step explanation:
The question relates to the requirements for workplace-based labels in a laboratory setting. These labels are crucial for conveying important information about chemicals and substances used in the lab. The four requirements of workplace-based labels include: hazardous material type, precautionary measures, first aid information, and expiry date. This information ensures that anyone handling the chemicals or coming into contact with them can do so safely, recognizing the risks and necessary precautions. Labels often include a hazard diamond, which summarizes potential dangers associated with a particular substance. Additionally, knowing where specific safety equipment, such as a fire extinguisher or eyewash station, is located and understanding general safety guidelines are fundamental to ensuring a safe working environment.
