NFPA 350 PDF

Help keep workers safe and minimize deaths, injuries, and illnesses by referencing NFPA 350, Guide for Safe Confined Space Entry and Work.

Each year, hundreds of accidents and incidents occur in locations classified as confined spaces, leaving workers and emergency responders at risk of myriad hazards that are not controlled as they are in occupied spaces. NFPA 350, 2022 edition, provides comprehensive information and guidance on better protecting workers from confined space dangers ranging from entrapment and drowning to asphyxiation and toxic chemical exposure.

This vital document is designed to provide direction for increasing the effectiveness of a confined space safety program and to assist in complying with regulations such as OSHA 29 CFR 1910.146 and 29 CFR 1926, Subpart AA. NFPA 350 offers easier-to-understand terminology and fills gaps not accounted for by current legislation.

NFPA 350 also is intended to assist fire and emergency services personnel in creating and assessing confined space rescue plans in combination with NFPA 1670, Standard on Operations and Training for Technical Search and Rescue Incidents.

NFPA 350 covers the following confined space safety topics:

• Identification of confined spaces
• Evaluation of hazards
• Atmospheric monitoring
• Hazard elimination and control
• Ventilation types, selection and design, equipment, and installation
• Rescue and rescue planning
• Confined space personnel duties, responsibilities, and competencies
• Pre-entry evaluation forms and permits
• Management of change (MOC)
• Prevention through design (PtD)
