Final answer:
Employers are responsible for keeping an updated binder of all Safety Data Sheets, which include critical information on handling, hazards, and disposal of chemicals.
Step-by-step explanation:
It is the employer's responsibility to maintain a binder of all Safety Data Sheets (SDSs) for the workplace. SDSs provide vital information on how to handle chemicals safely, their potential hazards, and the proper disposal methods to protect both individuals and the environment. Legally, employers must ensure that these sheets are readily accessible to all employees who may come into contact with the chemicals, and they must be kept up-to-date. When dealing with any new chemical, it is paramount to consult the SDS to familiarize oneself with its properties and the precautions needed for its use.
