Understanding the differences between OSHA, ASME, and ANSI is critical for maintaining compliance, especially in construction, where crane operation and rigging are aspects of the job. For many operators, riggers, and industry stakeholders, OSHA, ASME, and ANSI govern various industries, including rigging and crane operations.
However, understanding how each body works and how it influences compliance, safety, and industry best practices is not always clear. This guide by CICB breaks down the roles of these three organizations, how they work together, and how they differ.
Here is an overview of the Occupational Safety and Health Administration (OSHA), how it works, and its relevance to crane operation and the lifting sector.
OSHA is a federal agency that operates under the U.S. Department of Labor. Its primary mission is to set and enforce workplace safety regulations to help maintain safe, healthy working conditions. Unlike ASME and ANSI, OSHA has a legal authority to enforce regulations that employers must comply with.
The OSH Act of 1970 was established to cover private employers and their workers, granting employees the right to workplaces free of safety and health hazards. Under this federal law, workers are allowed to speak up and protect these rights without fear of retaliation from their employers.
OSHA regulates employers and workplaces, focusing on how work is performed and how workers are protected. Employers must keep up with:
Crane and rigging requirements are primarily addressed in two OSHA regulations — 29 CFR 1926 Subpart CC (Construction) and 29 CFR 1910 (General Industry). These regulations cover topics such as operator qualification and certification, inspection requirements, signal person, and load-handling procedures. Here is a look at some of these requirements:
Here is an overview of the American Society of Mechanical Engineers (ASME), the focus of its standards, and how these standards influence rigging and lifting.
ASME is a professional organization that develops technical standards for mechanical equipment and systems. While ASME is not a regulatory body and does not enforce requirements, many of the organization's standards are adopted and enforced by OSHA. The organization comprises a vast network of experts from diverse backgrounds, including engineering, academia, science, and law.
This large network writes and sets standards, codes, and best practices across many industries. ASME establishes engineering standards in detail, elaborating on equipment design, construction, testing, inspection, and maintenance.
ASME standards focus primarily on the physical and mechanical aspects of safety. It provides the technical rules that govern how safe equipment performs under expected operating conditions. In crane operations and rigging, these standards establish the engineering framework that supports safe operations and OSHA regulatory compliance.
Some of the aspects that ASME standards cover include:
If your business uses rigging equipment and cranes, your operations are informed by ASME standards, particularly those found in the ASME B30 standards. The comprehensive series covers a wide range of lifting and material handling equipment, including:
Each standard defines safe working loads for specific equipment, inspection intervals, operating conditions, and criteria for decommissioning. These details are key to preventing mechanical failures during operation and protecting worker safety.
While ASME standards are not law and are technically voluntary, they carry significant weight. OSHA frequently adopts these standards, effectively turning them into enforceable regulations. In cases where some of these standards are not explicitly referenced, they are still recognized for establishing accepted industry practice. When an accident or a legal violation occurs, OSHA inspectors, investigators, and courts often refer to ASME standards to determine whether the equipment involved in the incident was used properly.
Below is an overview of the American National Standards Institute (ANSI), its focus, and its role in crane and rigging safety.
ANSI is an accreditation organization that oversees the development of voluntary standards for systems, products, and services in the U.S. The organization comprises industry experts, manufacturers, labor representatives, government agencies, and other stakeholders. ANSI strives to strengthen the United States' position in the global arena by overseeing standards that maintain quality and consistency across multiple industries.
While ANSI itself does not write standards, it enables the development of American National Standards by accrediting various organizations that develop standards through a balanced, consensus-based process.
ANSI standards concentrate on how work is performed in operating environments. While OSHA sets legal requirements and ASME outlines equipment engineering aspects, ANSI fills a vital gap by standardizing safe procedures and performance expectations. These standards are designed to reduce human error and improve consistency, especially in high-risk operations like rigging and lifting.
The focus on performance and behavior enables ANSI standards to translate regulatory and engineering requirements into practical steps that workers can implement. Here is a breakdown of ANSI coverage:
In crane and rigging operations, ANSI standards are more concerned about work performance. That means standardizing safety practices such as hand signals, signage, safety colors, and other elements that support clear communication and hazard awareness. These standards are critical because they are developed through industry consensus, reflecting real-world experience and updated best practices.
Like ASME, ANSI is not involved in regulatory compliance. Its standards are voluntary recommendations from industry experts. However, since ANSI standards outline best practices to enhance workplace safety, they are often adopted by OSHA, effectively requiring employer compliance. They are also frequently cited during litigation or accident investigations as evidence of what reasonable approaches should look like.
While these three organizations uphold worker safety and advance industry standards, the most important distinction between them is their authority and purpose. Here are the key differences between OSHA, ASME, and ANSI.
OSHA is the enforcer, which means it focuses more on upholding regulations and is less concerned with how standards are developed. Since this government agency enforces standards set by ASME, ANSI, and manufacturers, noncompliance by an employer could result in penalties, which range from fines to operational shutdowns.
ASME develops standards for mechanical engineering, emphasizing technical specifications. It does not have the power to enforce its standards. However, local jurisdiction and insurance providers often require compliance with ASME guidelines. Remember, ASME standards are part of ANSI’s approved American National Standards.
While you will hear references to ANSI standards, it is important to keep in mind that ANSI does not write standards. It acts as a facilitator and accredits the processes of organizations that develop standards, like ASME. It approves the guidelines developed by these organizations as part of its unified American National Standards.
OSHA, ASME, and ANSI are interconnected. To translate regulatory understanding into everyday practice, it is essential that organizations implement a structured alignment process that merges legal requirements, operational approach, and engineering codes. This checklist provides a practical compliance roadmap for crane operation and rigging.
In high-stakes sectors such as rigging and crane operations, ASME, ANSI, and OSHA work together to provide a layered approach to regulatory compliance and operational safety. While ASME develops technical specifications for the design of equipment and accessories, ANSI reviews these specs to confirm that they meet national consensus requirements. OSHA issues regulations mandating that employers operate in accordance with these recognized standards.
When these frameworks are applied together, workplace safety becomes proactive. Additionally, employers are better prepared to maintain updated compliance planning.
