Oregon OSHA Confined Space Safety training workbook outlines the core requirements and procedures for permit-required confined spaces under OR-OSHA Division 2/Subdivision J, 29 CFR 1910.146. It helps employers and responsible staff determine whether workplaces contain confined spaces, then identify permit-required confined spaces based on hazardous atmospheres, potential for engulfment, dangerous conditions, or other serious hazards. The material emphasizes evaluating conditions, recognizing examples, and conducting air monitoring because atmospheric risks can change rapidly.

For example, some confined spaces pose entrapment hazards for entrants, while others restrict air circulation so that hazardous atmospheres can accumulate. Confinement itself can increase the risk of injury or death by making employees work closer to hazards than they would otherwise. Safety and health professionals have long recognized and directed employer and employee attention to the significant dangers of confined spaces. This workshop introduces you to the basic requirements and procedures involved with permitrequired confined spaces as described in OR-OSHA Division 2/Subdivision J 29 CFR 1910.146, Permit-Required Confined Spaces. This information is vitally important to all those who work in or have responsibility for those who work in permit-required confined spaces (PRCS). Please feel free to ask questions at any time. If you have experience in confined space operations, please participate so that we might all benefit from that experience! Goals • Review criteria for confined spaces and permit-required confined spaces • Describe the hazards which exist in permit-required confined spaces • Describe the steps in developing a permit-required confined space program • Review training requirements Please Note: This material, or any other material used to inform employers of compliance requirements of Oregon OSHA standards through simplification of the regulations should not be considered a substitute for any provisions of the Oregon Safe Employment Act or for any standards issued by Oregon OSHA. This workbook is intended for classroom use only. Confined Space Safety This material is for training use only Evaluate Your Workplace The OR-OSHA standard applies only to permit-required confined spaces. However, a permit-required confined space must be a confined space first. 1. Does your workplace contain confined spaces? A confined space is... 􀀁 Large enough for the whole to enter and work, and 􀀁 Has entry or exit, and 􀀁 Is not for continuous occupancy. Restricted (or limited) entry or exit exists when an entrant’s ability to self-rescue is hindered. Common examples include small openings, ladders, and long tunnels. 2. Does your workplace contain permit-required confined spaces? A permit-required confined space is a confined space that contains one or more of the following characteristics... 􀀁 Contains or potentially contains a hazardous a , or 􀀁 Has potential f

FAQs

What determines whether a space is classified as a confined space under the OR-OSHA standard?

A confined space must be large enough for entry and work, have a means of entry or exit, and not be designed for continuous occupancy.

When is a confined space considered permit-required?

It is permit-required when it contains or potentially contains hazardous atmospheres, has potential for engulfment, has dangerous conditions, or includes other recognized serious safety or health hazards.

Why is air monitoring essential for permit-required confined spaces?

Hazardous atmospheres are a leading cause of death, atmospheric conditions can change quickly, and air monitoring is required to determine whether a hazardous atmosphere exists.
