WASHINGTON -- Small bus operators are exempt from a federal requirement that employers report and post a summary by April 30 of all job-related injuries and illnesses that occurred last year.

The U.S. Occupational Safety and Health Administration is requiring companies with more than 10 employees to complete OSHA Form 300A between Feb. 1 and April 30. The form tallies job-related injuries and illnesses, the average number of employees and total hours worked during the year.

Small coach fleets are exempt, said OSHA spokesman Frank Meilinger. "They are only required to report if they have any fatalities or if the Bureau of Labor Statistics asks them to participate in its annual survey," Meilinger said.

Companies required to complete the form, but had no recordable injuries or illnesses last year, simply enter zeros on the total line. All summaries must be certified by a company executive.

A copy of the report should be displayed in a common area wherever notices to employees are normally posted. Copies must be available to employees who move from worksite to worksite and employees who report to no fixed establishment on a regular basis.

Copies of OSHA Forms 300, 300A and 301 are available at www.osha.gov/pls/publications/pubindex.

All employers, including those partially exempted by reason of company size or industry classification, must report to OSHA any workplace incident that results in a fatality or the hospitalization of three or more employees.
