Permit Required Confined Spaces 29 CRF 1910.146

www.csem.com offers Safety classes and courses on OSHA’s Permit Required Confined Spaces standard, CFR 1910.146.  The training is designed to protect workers who enter permit-required confined spaces and help employees quickly determine if a space is a confined space or a permit required confined space. General industry and construction employers are covered by this rule. The goal of the www.csem.com program is to satisfy the requirements of the law and offer the employee a certification of successful completion of the training for the employer to be able to maintain their compliance under the law.
