1. Scope
This safe work procedure (SWP) outlines the requirements for safe entry into confined spaces at forging facilities, specifically addressing hydraulic press pits and forge furnaces. It applies to all employees, contractors, and visitors who may be required to enter a confined space at the facility. This procedure is designed to comply with all applicable safety regulations and standards related to confined space entry. The procedure includes guidelines for hazard identification, risk assessment, permit issuance, entry procedures, and emergency response.
2. Definitions
Confined Space A space that is large enough for an employee to enter, has limited or restricted means of entry or exit, and is not designed for continuous employee occupancy. [9]
Permit-Required Confined Space A confined space that contains or has the potential to contain a hazardous atmosphere, contains a material that has the potential for engulfing an entrant, has an internal configuration that could trap or asphyxiate an entrant, or contains any other recognized serious safety or health hazard. [8]
Entry Permit A written authorization that allows entry into a permit-required confined space, verifying that pre-entry procedures have been completed and the space is safe to enter. [3]
Attendant An individual stationed outside the confined space who monitors the entrants, maintains communication, and performs rescue duties as needed. [4]
Entrant A trained and authorized employee who is allowed to enter a confined space to perform work. [3]
