Safety Data Sheets (SDS) must be ___________ and updated when new information is available.

Safety Data Sheets (SDS) are critical documents that provide essential information about hazardous materials, including their potential health effects, handling instructions, and emergency measures. The requirement for SDS to be completely legible ensures that the information is clear and accessible for all users, which is vital for maintaining safety in the workplace.

When SDS are completely legible, it allows workers to understand the risks associated with the chemicals they may be handling and informs them of the necessary precautions to take. If the information is not fully legible, there could be misunderstandings that lead to improper handling or exposure to hazardous substances, resulting in accidents or health risks.

In addition, the stipulation that SDS must be updated when new information becomes available reflects regulatory compliance and best practices in safety management. Keeping these documents up to date ensures that all safety protocols align with the latest data regarding chemical handling and risks, thereby safeguarding the health of all personnel involved.

The other options do not adequately address the necessity of clarity and accessibility of the information contained within Safety Data Sheets, which is fundamental to effective workplace safety procedures.
