OSHA upholds the safety of the workforce through the following methods:

Inspections
Severe Violator Enforcement Program
Whistleblower Program
However, OSHA has only 2,000 inspectors to monitor the 8 million employers and 130 million workers under its jurisdiction. Therefore, it conducts inspections only under the following circumstances:

Imminent danger situations
Fatalities and catastrophes
Complaints registered by employees
Referrals from other agencies
Follow-up inspections for worksites previously found to be in violation of OSHA health and safety standards
Planned or programmed investigations of targeted industries or areas
This makes OSHA inspection assume extra significance. But it need not be. By creating an OSHA inspection checklist and diligently adhering to it, you can minimize the chances of an OSHA inspection.
