According to OSHA’s Process Safety Management (PSM) standard (29 CFR 1910.119), all documentation related to a Process Safety Analysis (or Process Hazard Analysis, PHA) — including findings, recommendations, and corrective actions — must be retained for the life of the process.
That means if a chemical process or operation continues for 10, 20, or even 30 years, the original and updated PHA records must be kept for that entire duration. These records are essential because they help track how process risks were identified, evaluated, and controlled over time.
Even when a process is modified or updated, the old PHA reports remain valuable references for understanding historical safety decisions and lessons learned.
Only when the process is permanently shut down or decommissioned can the records be archived or disposed of.

What are the limiting assumptions of C-V-P analysis?
I am interpreting the question as above as Cost Volume Profit(CVP) analysis. If this is not so, my answer below will not be correct. First of all, CVP is used in Finance or Accounting, to describe the behaviour of cost, revenue and profit. Other disciplines also use this analysis, and will be called a different name. In Business Management, it's often called Break Even Analysis. One of limiting assumptions of CVP analysis is the assumption of a linear function of the variable cost and total cost. This means that the cost of a business will increase in a proportional manner, if I make 2 units of output, the cost is 4, if I make 4 units of output, the cost is 8. While this may be possible in theory, it reality, it's not so. If we assume that the cost is linear, the Variable Cost and the Total Cost will be a straight line. In reality, the variable cost doesn't increase in along a straight line. ( not so perfect in reality ). Apart from that, the CVP analysis also assumes that there are no stocks present. The analysis just shows that goods are sold and the company has no stocks kept. Although these can be seen as a limiting assumptions of the CVP analysis, it's important to understand it provides an understanding to students who are new to it. In Economics, the CVP analysis is more complicated, with the variable cost and the total cost function a curve. This means that the cost will fall initially and then increase later. Apart from that in other Ecnomics, costs are considered with the short run and long run perspective. Costs may not be the same in short run and long run.
