He will use all of the solvent himself during the next few minutes and will not leave the bucket unattended. What is the employer's labeling obligation for the bucket?
Show answer and source
Answer: D. No workplace label is required because it is a portable container intended only for the immediate use of the employee who made the transfer
The standard exempts portable containers filled from labeled containers when they are intended only for the immediate use of the employee who performs the transfer. The other choices invent requirements or time limits that the standard does not contain.
“The employer is not required to label portable containers into which hazardous chemicals are transferred from labeled containers, and which are intended only for the immediate use of the employee who performs the transfer.”
