What is OSHA?

Occupational health and safety is an essential part of the modern workplace, though some industries are a lot more dangerous than others. U.S. employees rely on the strict standards set by federal agencies like the Occupational Safety and Health Administration (OSHA) in cases where hazards are an inevitable part of the day-to-day working environment. OSHA works to reduce workplace injuries, illness, and fatalities through education, compliance, and enforcement. Individuals looking to pursue a meaningful career in public health may benefit from learning more about this essential organization and how it has reshaped the modern workplace.


A brief history of OSHA

OSHA was established in 1971 following a period of intense public outcry concerning U.S. working conditions. At the time, occupational injuries and illnesses were becoming increasingly common ― disabling injuries increased 20 percent over the decade and an average of 14,000 workers died on the job each year, according to OSHA estimates. Workplace hazards like deafening noise, poor ventilation of cotton dust, and exposure to asbestos were hotly debated, prompting government officials to seriously consider safety and health legislation.


Following President Nixon’s signing of the Occupational Safety and Health Act of 1970 ― often called the Williams-Steiger Act―three permanent agencies were officially created, each with its own specific operational guidelines:

  1. The Occupational Safety and Health Administration (OSHA) was given the responsibility of setting and enforcing workplace standards in an effort to reduce the frequency of injuries and illnesses that might otherwise be avoided.
  2. The National Institute for Occupational Safety and Health (NIOSH) was established to conduct thorough research on occupational safety and health to determine what risks existed and how they might be mitigated through regulatory action.
  3. The Occupational Safety and Health Review Commission (OSHRC) was formed as an independent agency to arbitrate any enforcement action brought against employers by OSHA and to provide a standardized procedure for challenging the other agencies’ findings.


While all three agencies worked toward the same goal, OSHA quickly took a leading role in the development of nationwide regulations. At its inception, the agency covered over 56 million workers at 3.5 million different workplaces by conducting physical inspections and bringing legal action against employers that failed to adequately protect their employees. Since then, OSHA has helped to reduce the rate of serious workplace injuries and illnesses from 11 per 100 workers to 3.6 per 100 workers in 2009. To understand how this reduction was accomplished, it’s important to fully comprehend what OSHA actually does in its line of work.

What does OSHA do?

Workplaces have continued to evolve since OSHA was founded, which has forced the agency to refine its standards and come up with new enforcement strategies. Initially, the agency focused on problem industries like manufacturing and large-scale construction, but it has changed its approach to instead pinpoint environments with high injury and illness rates. OSHA’s regulatory activities typically fall into three broad categories: education, compliance, and enforcement.



OSHA offers employer training and outreach programs to meaningfully address safety and health concerns in the workplace. This proactive approach has helped the agency forge lasting relationships with industries and organizations around the country. OSHA regularly provides safety seminars, training events, and personalized guidance to employers directly, while also updating its website with useful resources to accommodate remote learning. The agency’s website sees an average of 1.4 million visitors every month and has accumulated 23 million visits to date. Some of OSHA’s educational activities include:

  • Publishing process and management standards
  • Developing workplace safety manuals and other training materials
  • Providing free onsite consultations to identify workplace hazards
  • Partnering with local, state, and federal groups to reduce injuries, illnesses, and fatalities


In some cases, voluntary education programs are not enough to curb hazardous conditions in the workplace. OSHA sets strict compliance guidelines in the hopes of compelling employers from all industries to equip their operations with significant worker protections. For example, the agency has rules concerning fire protection and electrical safety, sanitation, emergency response, and hazardous chemical exposure. To keep its guidelines up to date with the challenges of modern occupational environments, OSHA has streamlined its standard setting process to include:

  • Collecting data from employers in high-hazard industries
  • Setting exposure limits for toxic substances
  • Conducting safety compliance and health inspections
  • Advancing employee medical and exposure recordkeeping practices
  • Progressing bloodborne pathogen standards to address biological hazards
  • Promoting processes for responding to workplace accidents


When employers fail to meet OSHA’s safety and health standards, the agency takes immediate action to ensure its regulations are adhered to moving forward. Regulatory enforcement can range from a simple written warning to severe monetary penalties for willful or repeated violations. In some cases, a serious violation may lead to a complete halt of all operations along with a thorough investigation of the employer’s workplace conditions. Originally, the maximum penalty for a serious OSHA violation was $1,000 to $7,000 per incident, but Congress increased this range to $10,000 to $70,000 in 1990. The agency’s regulation enforcement includes a range of activities, such as:

  • Creating rapid response procedures for worker complaints and workplace tragedies
  • Enforcing safety standards and instance-by-instance penalties
  • Adjusting penalty thresholds for companies with habitual violations
  • Pursuing legal action against employers that fail to comply

OSHA’s training initiatives, compliance standards, and enforcement actions have helped to protect U.S. employees from dangerous working conditions for over 40 years. Today, the occupational injury rate is 40 percent lower than it was when OSHA was founded, and workplace fatalities have dropped 60 percent. Despite this significant improvement, OSHA’s work is still as important as ever, and the agency relies on qualified health and safety professionals to maintain the positive trend.
