CS hazard identification. Describe the hazards in the CS and all potential hazards that may be created by potential work in the CS, any permanent air monitoring, physical isolation identification, or permanent ventilation;

Safe CSE conditions. Describe the practices and procedures that will be followed to assure that CSs will be entered safely. Procedures and practices must include but are not limited to the following:

(1) NPRCSs. Describe any monitoring and employee training that will assure non-permit conditions are maintained and that employees entering the NPRCS understand how to maintain a safe working environment while working in it.
