Individuals working in attics, crawl spaces, mines and other enclosed environments must learn about the hazards and safety precautions involved in their work. Many companies that require employees to work in this type of setting offer in-house training, designed in accordance with regulating bodies, which provides a customized program specific to the employee's work environment.
Programs for confined space entry are generally one day long and discuss topics that include Occupational Safety and Health Administration (OSHA) standards and regulations, appropriate protective equipment and the duties of all employees working in confined spaces, including attendants and supervisors.
Many employers require employees to participate in a refresher course at least once every three years. Furthermore, individuals are often advised to obtain training in other safety areas, as they pertain to each job. Other training course options include asbestos awareness training, personal protective equipment training and respiratory protection training.
