System safety application guidelines

Current guidelines for toxicity evaluation of ophthalmic formulations involve both single and multiple applications, dependent on the proposed clinical use [39]. The multiple applications may extend over a 9-month period and incorporate evaluations of ocular irritation and toxicity, systemic toxicity, and determinations of systemic exposure (toxicokinetics). In many cases the systemic exposure from an ocular route is less than by parenteral administration, information that will assist in determining whether additional studies may be needed to establish systemic safety of the ophthalmic preparation. U.S. and international guidance documents are available [71,72], and regulations and tests have been summarized for ophthalmic preparations [39,73,74],... 

After the System 80+ applicable issues were identified, a methodology for the documentation of the technical resolution of each issue was developed. Each applicable issue is comprised of four sections ISSUE, ACCEPTANCE CRITERIA, RESOLUTION and REFERENCES. The ISSUE statement section consists of a brief summary description of the safety issue. This is followed by the ACCEPTANCE CRITERIA section. These criteria are taken from NUREG-0933 in most cases, and, in the absence of a formal NRC resolution, developed from accepted industry codes, guidelines, standards and/or good engineering practice. The RESOLUTION section contains the technical resolution of the safety issue which is based upon the System 80+ Standard Design as described within CESSAR-DC or other pertinent documentation as listed in the REFERENCES section. This four part structure for each safety issue is intended to establish how each safety issue is resolved in a clear and concise manner.

In parallel with the impact assessment, the usability of existing ITS applications for VRUs is assessed. An architecture is developed for the integration of VRUs in the traffic systems of the future, and methods for communication of safety critical information are assessed. The areas for improvement of the HMl for different VRU groups, such as elderly drivers and motorcycles, are identified. Starting from a usability study of current ITS applications, guidelines will be provided on the... 

Industry specific standards will be derived fi-om guidelines set down in lEC 61508. (Hence all control system safety related applications in any industry may in future be subjected to similar safety life cycle design requirements).

Read Chapter 2 of the CCPS publication Guidelines for Implementing Process Safety Management Systems, 1993, for guidance on obtaining buy-in. The principles described for obtaining support and commitment for PSM are equally applicable to integration of PSM and ESH. 

Good compound means formulas are developed that are environmentally safe, factory processable, provide a satisfactory service life, and are cost-competitive to other compounds used in the same applications. Costs are always a major concern and constantly increasing environmental safety regulations must not be overlooked. In this particular section, focus has been made on cure systems and formulations of practical interest. This provides a guideline for compounding in various applications. 

In 1993, the Center for Chemical Process Safety (CCPS) published Guidelines for Safe Automation of Chemical Processes (referred to henceforth as Safe Automation). Safe Automation provides guidelines for the application of automation systems used to control and shut down chemical and petrochemical processes. The popularity of one of the hazard and risk analysis methods presented in Safe Automation led to the publication of the 2001 Concept Series book from CCPS, Layer of Protection Analysis A Simplified Risk Assessment Approach. This method builds upon traditional process hazards analysis techniques. It uses a semiquantitative approach to define the required performance for each identified protective system. 

Computer systems validation, implied in 21 CFR Part 211.68, established in 21 CFR Part 11.10(a), and defined in the recent draft FDA guideline,4 is one of the most important requirements applicable to computer systems performing regulated operations. Computer systems validation is the confirmation (by examination and the provision of objective evidence) that computer system specifications conform to user needs and intended uses, and that all requirements can be consistently fulfilled. It involves establishing that the computer system conforms to the user, regulatory, safety, and intended functional requirements.
