A hazardous chemical has the GHS signal word 'Warning' on its label. What does this indicate compared to a chemical labeled 'Danger'?
Answer: Warning indicates a less severe hazard than Danger
'Warning' signals a less severe hazard category, while 'Danger' is reserved for the most severe hazard categories within a class.
On a construction site, a worker needs to transfer a hazardous chemical into a smaller portable container for immediate use. Under HazCom, is a label required on the portable container?
Answer: No, if the worker who filled it will use it exclusively during that shift
OSHA allows an exemption from labeling for portable containers filled by workers for their own immediate use during the same shift.
What is the primary purpose of the written Hazard Communication Program that employers must maintain?
Answer: To describe how the employer will implement all elements of the HazCom standard
The written HazCom program explains how the employer implements labeling, SDS management, and employee training requirements.
A construction supervisor receives an SDS written in a foreign language for a chemical purchased overseas. What must happen before the chemical can be used on a US job site?

OSHA requires SDSs to be in English (and any other language predominant in the workplace), so an English SDS must be available before use.
