Safe work practice procedures

As discussed in Chapter 2, The Toller Selection Process, evaluating the site s safe work practice procedures should have been a part of the review during the toller selection process. Still, new materials may indicate a need to revise or develop special procedures to address unique chemical and physical hazards. New hazards such as vacuum, ciyogenics, ultra-high pressure, or new rotating equipment could be introduced. Medical monitoring requirements or special handling and spill response procedures for the toll s raw materials and products may indicate a need to write or revise safe work practices. 

Laboratoiy procedures may need to be evaluated against the sampling techniques and materials involved in the toll. There may be new laboratoiy chemicals and hazards to be considered. This work may have been identified in the evaluation of special analytical techniques required for the process. A good practice is to ensure that the lab technicians have the necessaiy guidance and types of equipment on hand to monitor the process and waste streams accurately and safely.

Other information may also benefit the PHA. Standard operating procedures for processing equipment, safe work practices, maintenance or job safety analyses, emergency response plans could be appropriate review items for some PHAs depending upon the toll. 

Tolling presents a special consideration that can make the training step easier. Typically a toller s technical staff, operators and mechanics are knowledgeable in the basic operations and tasks related to the toller s specialty. For example, experienced operators may know operations of the reactors, columns, exchangers, and packaging equipment quite well. The mechanical personnel may be very familiar with the required safe work practices, equipment cleaning procedures and maintenance tasks for standard vessels and piping.

This tragedy emphasizes the importance of safe work practices especially for situations that have not previously been encountered. A contingency plan should have been drawn up to address the possibility of the solid mass releasing from the wall. Complacency, inexperience, and desire to get the job done may have overshadowed the need to develop safe work procedures. 

The mechanical integrity procedures must also embody the safe work practices as well as the detailed equipment procedures. Safe work practices include Lock and Tag, Confined Space Entry, Welding, Burning and Open Flame, and similar essential personnel safety procedures. Detailed equipment procedures include generic procedures, equipment specific procedures, and manufacturers procedures. 

Employees involved in maintaining the ongoing integrity of process equipment must be trained in an overview of the chemical process and its hazards. Employees must be also trained in the procedures applicable to the employees job tasks, such as the safe work practices discussed above.
