• Employers must maintain separate OSHA 300 Logs for each establishment, if the business includes multiple establishments.

When an employer has multiple business establishments, it must keep a separate Occupational Safety and Health Administration (OSHA) 300 Log for each one that is expected to be in operation for a year or longer.

An establishment is a single physical location where business is conducted or where services or industrial operations are performed. For activities where employees do not work at a single physical location, such as construction, transportation, communications, electric, gas and sanitary services, and similar operations, the establishment is represented by main or branch offices, terminals, stations, etc. that either supervise such activities or are the base from which personnel carry out these activities.

For short-term establishments, employers can keep one OSHA 300 Log that covers all the short-term establishments and include the short-term establishments’ recordable injuries and illnesses on an OSHA 300 Log that covers short-term establishments for individual company divisions or geographic regions.

Can records be kept at company headquarters or another central location?

An employer may keep records for an establishment at its headquarters or other central location if the employer can:

• Transmit information about the injuries and illnesses from the establishment to the central location within seven calendar days of receiving information that a recordable injury or illness has occurred; and
• Produce and send the records from the central location to the establishment within the time frames required by 1904.35 and 1904.40 when required to provide records to a government representative, employees, former employees, or employee representatives.

How do employers keep records for employees who work at several different locations or do not work at an establishment?

For recording purposes, employees who work at several different locations or do not work in a specific location at all will need to be linked to one of the employer’s business locations.

When an employee from one location is injured or becomes ill while visiting or working at another of the same employer’s locations, the injury or illness should be recorded on the OSHA 300 Log of the location at which the injury or illness occurred. If an employee is injured or becomes ill while working away from any of the employer’s business locations, record the case on the 300 Log at the location where the employee normally works.
