Your business is subject to different posting requirements under OSHA rules:
Regardless of the size of your business, if you have any employees you must display posters that inform employees of their job safety rights. Spanish and English copies of these posters (OSHA 3165 and 3167) are available at the OSHA web site.
MSDSs must be available and displayed prominently in the workplace.
If your company is required to complete the Forms 300 and 300A (generally speaking, employers with more than 10 employees that are not exempt), Form 300A must be posted in the workplace from February 1 through April 30 each year even if there are no illnesses or injuries reported.
Penalties. Failure to follow these posting requirements may result in a citation during an OSHA inspection.
