How does OSHA define a "hazardous chemical"?
Any chemical used in manufacturing
Any chemical with a flashpoint below 100°F
Any chemical which is classified as a physical or health hazard
Any substance requiring PPE
OSHA defines a hazardous chemical as any substance that poses a physical or health hazard. This includes flammables, toxins, irritants, and more. Classification follows GHS criteria.
According to OSHA HCS, what is the minimum font size required for signal words on GHS-compliant labels?
12-point font
6-point font
8-point font
No minimum specified
OSHA requires that signal words be prominent and legible but does not specify a numeric font size. The key is visibility and readability. Employers must choose a size that ensures clarity.
When must employers provide hazard communication training to their employees?
Only at hire
Annually
At initial assignment and before new hazards introduced
Upon OSHA inspection
OSHA mandates training at the time of initial assignment and before employees are exposed to new hazards. There is no fixed annual requirement, but training should be updated as hazards change. This ensures ongoing safety.
According to OSHA, which SDS sections are considered non-mandatory but recommended?
Sections 12-15
Section 16 only
Sections 1-3
Sections 4-11
OSHA requires SDS sections 1-11 and 16; sections 12-15 (e.g., ecological, transport, regulatory, other) are not mandatory under OSHA but are recommended for alignment with GHS. These sections aid comprehensive hazard management.
What hazard class does the GHS health hazard pictogram primarily represent?
Oxidizers
Explosives
Carcinogenicity and respiratory sensitization
Corrosives
The health hazard pictogram covers serious health effects such as carcinogenicity, respiratory sensitization, reproductive toxicity, and specific target organ toxicity. It warns of chronic hazards. OSHA labels use this symbol accordingly.
Which GHS pictogram is NOT enforced under OSHA but provided for informational purposes?
Environmental (aquatic toxicity)
