When do I post the Cal/OSHA Log 300?

Employers do not have to post the Log 300; however, they must post a Summary (Form 300A) of the total number of job-related injuries and illnesses that occurred the previous year. The Summary for the previous year should be posted from February 1 to April 30, every year.

What to Post

The summary must list the total number of job-related injuries and illnesses that occurred the previous year and were logged on the Log 300 form. Employment information about the annual average number of employees and total hours worked during the calendar year also is required to assist in calculating incidence rates.

Companies with no recordable injuries or illnesses must post the form with zeroes on the total line. All establishment summaries must be certified by a company executive.

The form is to be displayed in a common area where notices to employees usually are posted. Employers must make a copy of the summary available to employees who move from worksite to worksite, such as construction workers, and employees who do not report to any fixed establishment on a regular basis.

Exempt Employers

Employers with 10 or fewer employees and companies that are classified in a low-hazard Standard Industry Classification (SIC) normally are exempt from injury and illness recordkeeping and posting requirements. Our Log 300 wizard can help a business determine whether it is subject to record keeping requirements. 

Exempt employers still may be selected by the U.S. Labor Department’s Bureau of Labor Statistics to participate in an annual statistical survey. All employers covered by California’s safety and health regulations need to comply with safety and health standards and must report verbally within eight hours to the nearest OSHA office all fatal accidents or the hospitalization of three or more employees.

Employer Responsibility

Employers are responsible for providing a safe and healthful workplace for their employees. OSHA’s role is to assure the safety and health of America’s workers by setting and enforcing standards; providing training, outreach and education; establishing partnerships; and encouraging continual improvement in workplace safety and health.​​
