What is a potential risk if there's no back-up system for MSDS access?

The potential risk of not having a backup system for Material Safety Data Sheets (MSDS) access primarily revolves around the inability to obtain vital information during emergencies. In situations where hazardous materials are involved, immediate access to safety information is crucial to ensure proper handling, response, and mitigation measures are taken to protect personnel and the environment. An absence of a reliable backup means that if the primary system is down or inaccessible, critical safety information could be lost, leaving staff ill-equipped to respond effectively in emergencies. This could lead to severe consequences, including injuries or accidents.

While the other options may present challenges, they do not directly equate to the immediate danger posed during a crisis when MSDS information is needed to guide personnel actions swiftly. The fundamental role of MSDS is to provide safety information, and without access when it's needed most, the risks escalate significantly.
