OSHA Confined Space Safety
29 CFR 1910.146 Confined Space Safety Standard
Pay just $19.95 for your OSHA Confined Spaces certificate.
Many workplaces contain spaces that are considered to be confined because their configuration hampers the activities of employees who enter into, work in, or exit from these spaces.
In many instances, employees who work in confined spaces also face an increased risk of exposure to serious physical injuries from hazards like entrapment, engulfment and hazardous atmospheric conditions.
Confinement in itself can pose entrapment hazards , and work in confined spaces may keep employees closer to hazards like machinery components.
Confinement, limited access and restricted airflow can result in hazardous conditions that would not normally occur in an open work space.
The terms ‘permit-required confined space’ and ‘permit space’ refer to spaces that meet OSHA’s definition of a ‘confined space’ and contain health or safety hazards. For this reason, OSHA requires workers to have a permit to enter these spaces.
The first four modules in this course focus on confined spaces in general industry. They explore the types of confined spaces an employee may enter and the type of training needed to protect from the hazardous materials that may exist inside a confined space.
The final module covers the basics of confined space in the construction industry.
