OSHA 10 certification is a training program designed by OSHA (Occupational Safety and Health Administration) to teach basic safety and health information to entry-level workers in construction and general industry. The training is voluntary, but some employers may require workers to earn an OSHA 10 card before starting work, and it is mandatory in certain states, cities, and local jurisdictions. The training covers critical workplace safety topics, and entry-level workers who complete the training have industry-specific knowledge and skills that help prevent injuries and keep workplaces safe and productive. The OSHA 10 certification is issued to workers who complete 10 hours of OSHA Outreach training on industry-specific workplace safety topics. The certification is proof that the worker has completed the training and has the necessary knowledge and skills to work safely in their industry. The certification is valid for five years from the date of completion.
