Answer
A. Deny the claim based on ADA
B. *Pay 100% for a new injury

According to the Global Harmonization System (GHS). Safety Data Sheets shall be readily ac-
cessible during each work shift to employees when they are in their work area. The most ef-
fective way to handle this tasking is to?
Answer
A. Maintain copies of the SDSs in each work area
B. Maintain a central data base of SDSs
C. Provide a copy of SDSs by CD-ROM
3
, D. *Post the SDSs on the company local area network
Reference
The most effective way is to post all Material Safety Data Sheets is by use of the company lo-
cal area network (LAN) and a data base program. This allows updates to be posted when
they are received and are available to all work areas as soon as they are posted.
