The Massachusetts crane hand signals were developed by the American National Standards Institute (ANSI) in collaboration with the American Society of Mechanical Engineers (ASME). This partnership was established to create standardized signaling methods that ensure safe and effective communication during crane operations. The use of consistent hand signals helps minimize the risk of accidents on job sites by providing clear and universally understood commands.

The importance of having established signals cannot be overstated, as effective communication is crucial in environments where cranes are in operation. Standardized signals reduce misunderstandings, thereby enhancing overall safety for operators, crew members, and bystanders.

Other organizations, like the International Safety Organization, OSHA, and the National Institute of Standards and Technology, contribute to various safety standards and regulations in the workplace, but they did not specifically develop the crane hand signals utilized in Massachusetts.
