A worker mixed chemicals that caused a release of toxic gas. In the past, other workers made the same mistake. Which step should the Occupational Safety and Health Administration (OSHA) take in response?

Because the same mistake has happened before and caused a toxic-gas release, OSHA should investigate the workplace to identify how the incident occurred and what hazards or procedures need to be corrected. An inspection can help OSHA determine whether safety rules were followed and what changes are needed. The best choice is to inspect the workplace, rather than leave standards unchanged or focus on health research.
