Operating instructions and procedures

The preceding chapters have shown how to assess chemical reaction hazards and design a safe process. Once a system of safe operation has been selected it should be recorded, operated correctly and its performance monitored. This needs written procedures covering

After getting a clear confirmation that there is nothing wrong, one may proceed to step up the production rate slowly till the rated capacity is reached and all operations are stabilised. Fine-tuning of the plant units may now commence till best performance levels are achieved. AU standard operating procedures and instructions for dos and don ts are to be obtained from original equipment manufacturer (OEM) and discussed with senior engineers. The plant shall be run thereafter as per instmctions. 

In all cases, a very important analysis and control effort should be initiated and, if sufficient data are available, completed during the production phase. The operating hazard analysis (OHA) focuses on the human interface with the end product. It examines the adequacy of maintenance and operating procedures and instructions and, if appropriate, the adequacy of the organization and training of maintenance and operations personnel. The recommended technique for completing the OHA is the project evaluation tree (PET) analysis.
