Locking out machinery and equipment prior to servicing or maintenance is an essential element of protecting Iowa State University employees from the unexpected start up or release of stored energy. To address this issue and to comply with the Occupational Safety and Health Administration's (OSHA) lockout/tagout (LOTO) standard, EH&S has developed the Lockout/Tagout Manual and periodically offers lockout/tagout training to university employees. By following procedures in the manual and training, the university ensures that:

  • Effective lockout/tagout procedures are used to isolate and control hazardous energies.
  • Proper employee training is provided to both authorized and affected employees (authorized and affected employees are defined in Appendix A of the Lockout/Tagout Manual).
  • Periodic inspections are performed to verify that LOTO policies are being followed.
