Checklists modification

Checklist modification The critical safety behaviour checklists are modified as new areas of potentially unsafe behaviour are recognized. All employees are encouraged to identify items for inclusion on the checklists. 

Once the PSSR team is satisfied with their review, a form such as Example 4-1, Pre-startup Safety Review Completion Form can be used to capture their approval for startup. For simple changes, this one-page form may be all that is required. In the case of extensive modifications, a detailed checklist of items examined by the team may accompany this form. It could include unsatisfactory findings as well as respective recommendations. If recommendations were made, these must be prioritized. Some may need to be resolved before startup others may be appropriately addressed after processing has begun. Some items reviewed by one company for extensive modifications and logged in addition to the one-page form are ... 

You can choose any of a number of methods for conducting these checks. One involves developing a systematic checklist or grid that displays the criteria themselves and checks each modification against them. In addition, as with previous exercises, it s often useful to call on your colleagues on the PSM team, or on other advisors, and ask them to play devil s advocate. It s often useful to combine methods such as these, because together they yield both a quantitative assessment ("Does this modification do what we said we wanted it to do ") and a more qualitative judgment ("Will this modification work in actual practice "). 

An effective management system to ensure process integrity is essential and must include up-to-date operating procedures, product changeover instructions, and checklists that cover instrumentation, equipment arrangement, and procedures procedures must also include adequate checks and reviews to ensure the required changeover modifications have, in fact, been made when required. 

The checklist is divided into three areas 1) Material Storage and Handling, 2) Production Processes and 3) Treatment Alternatives. Material degradation, samples, spills, storage, and inspections are addressed in the first section. Production processes include source reduction for process bath solutions and rinse systems, resource recovery and recycling, and solvent management. Treatment Alternatives focuses on process water pretreatment, modification of conventional wastewater treatment, and alternative waste treatment methods. Each of these subsections follow the question and answer format.

Adherence to good engineering practice means that the modification is reviewed and compared to corporate or plant standards, state and local codes, insurance regulations, and societal codes. Many companies have developed excellent checklists or standards based upon years of experience with the manufacture, use, and handling of various chemicals. 

HAZOP and What-If reviews are two of the most common petrochemical industry qualitative methods used to conduct process hazard analyses. Up to 80% of a company s process hazard analyses may consist of HAZOP and What-If reviews with the remainder 20% from Checklist, Fault Tree Analysis, Event Tree, Failure Mode and Effects Analysis, etc. An experienced review team can use the analysis to generate possible deviations from design, construction, modification, and operating intent that define potential consequences. These consequences can then be prevented or mitigated by the application of the appropriate safeguards. 

The record of an experiment should begin with a brief statement of the experiment to be performed. The procedure being followed should be described in all essential detail. When the procedure is described elsewhere, the notebook entry may be abbreviated to a reference to the pubhshed description. However, be certain to record any variations from the published procedure and to specify the apparatus that was used (make and model for commercial equipment, otherwise a sketch). If various pieces of equipment have identification numbers or serial numbers, these should be recorded. Note also any date of modification for apparatus. Include any calibration constants or calibration curves that are provided. For each chemical substance used, record the name, formula, source, grade or stated purity, and concentration (in case of a solution). If you have developed a checklist or work plan for the experiment, record this in your notebook also. 

The. .. program has undergone six code modifications. Each of these code modifications was implemented after a Software and Test Case Review Checklist was completed. .. However, none of these six code reviews detected the. .. problem. .. which led to the current recall. [FDA Warning Letter, 1998]... 

The FDA has made several modifications to the tests required by Part 1 of the ISO 10993 standard for the category of surface devices that permanently contact mucosal membranes. The ISO does not require acute, subchronic, or chronic implantation tests as does FDA. FDA requires irritation, systemic toxicity, acute, subchronic, and chronic tests for external communicating devices, tissue/bone/ dentin with prolonged and permanent contact. Device manufacturers are advised to consider tests to detect chemical components of device materials that may be pyrogenic. This matrix is a framework and not a checklist and it is stressed by the FDA that necessary safety testing will be decided on a case-by-case basis. 

Recognize that modifications are hazardous. Many accidents have been caused by unforeseen side effects of even seemingly minor modifications. Ban "back of an envelope modifications, as their side effects can be worse than the original problem. Properly document any planned modification, and have a team review it systematically with the aid of a checklist such as a "hazop checklist (225). Before completion, inspect to ensure the modification was implemented as intended. 

These checklists are intended to be living documents, and should be modified as new interpretations of TSCA appear. To make a modification, contact... 

Having a well-crafted checklist for project reviews and for the development of contract specifications would be beneficial to engineers and safety professionals. A sample checklist follows which can serve as a base for the development of a checklist suitable to an organization. It is to serve as a guide only. To suit the checklist needs of any organization, additions, deletions, and modifications would be made. 

Checklists for further planning and major activities for the future (say next month or till next planned shutdown of the plant). This can include modification of plant units, major repair or replacement of some machineries (which may be possible only during a longer stoppage). 

This checklist is not intended to be comprehensive. Additions and modifications to fit local practice are encouraged. Revised i / 2009 who. 2009... 

Adapting the CRIOP checklists to a project can be time consuming. Identification of relevant corumonal-ities present in similar projects can he used to develop templates to make this adaptation more effective. Templates can he made for new CC design for an offshore installation, modification of the same, design of a new driller s cabin on a mobile unit, modification of the same etc.
