The Pressurized Welding Enclosure (PWE) User’s Manual is designed to provide comprehensive guidance for the safe setup, operation, and maintenance of P3 Global’s pressurized welding enclosures. PWEs are specialized containment systems engineered to create a controlled, positive-pressure environment that ensures safe hot work operations in areas where hydrocarbons or other hazardous substances may be present. This manual outlines the principles of operation, safety protocols, and step-by-step procedures necessary to ensure compliance with OSHA, NFPA, USCG, and international standards. It is intended for welders, supervisors, HSE professionals, and other personnel responsible for the installation and monitoring of PWEs in offshore and onshore environments.
