Verified step by step guidance

1. Understand that Safety Data Sheets (SDS) are documents that provide detailed information about the properties, hazards, handling, and emergency measures related to chemicals.
2. Recognize that SDS are required by regulations (such as OSHA's Hazard Communication Standard) to ensure worker safety and proper chemical management at workplaces.
3. Note that SDS must be available for all chemicals that are considered hazardous, and they must be accessible to employees at all times during work hours.
4. Eliminate options that suggest SDS are only provided upon request or are optional based on quantity, as these do not comply with safety regulations.
5. Conclude that the correct requirement is that an SDS must be readily accessible for every chemical used at the job site to ensure immediate availability of safety information.
