Hazards system safety

The hazards, system safety requirements and constraints, and documentation of the safety control structure for pharmaceutical safety were shown in chapter 7 Using these, Couturier performed several types of analysis.

A hazardous operation is a system operation that involves risk or danger. A hazardous operation is a hazard source for many different hazards associated with the operation. For example, a tethered walk in space from a spacecraft is a hazardous operation. If certain failures occur during the operation, the astronaut s life could be lost each of the potential failure modes would constitute a different hazard. System safety typically performs an O SHA to identify operational hazards.

Information on the types of human interactions with hazardous systems that occur would be obtained from sources such as plant operating instructions, job safety analyses and similar sources. These interactions are referred to as critical tasks (CT).

To properly apply the system safety techniques to die design and operation of potentially hazardous teclmologies, die design engineer must have a clear miderstanding of die system and be able to prepare a written response to questions such as ... 

After the type of system has been selected, many of these same factors must be considered in selecting the fluid for the system. This chapter is devoted to hydraulic fluids. Included in it are sections on the properties and characteristics desired of hydraulic fluids types of hydraulic fluids hazards and safety precautions for working with, handling, and disposing of hydraulic liquids types and control of contamination and sampling.

The commonly used management systems directed toward eliminating the existence of hazards include safety reviews, safety audits, hazard identification techniques, checklists, and proper application of technical knowledge. 

The primary document outlining risk assessment methods in the U.S. Department of Defense is a Military Standard, Ref. 39. This document requires a well-documented system safety program, based on risk assessment methods to be included in all new Department of Defense systems and facilities. Hazards analyses of the systems are mandated by this publication. 

This article shows, through example, how established system safety concepts can be used to develop safety criteria for the design of a chemical surety materiel laboratory. This systematic approach, when applied as described in this article, results in a laboratory dedicated to achieve mission objectives in an environment relatively free of inherent hazards for the least number of dollars. 

Facility System Safety (FSS), which is the application of system safety concepts to the facility acquisition process, has recently gained acceptance throughout the Department of Defense and most recently within the Department of Army with the conception of SAFEARMY 1990. The Army s goal is to fully integrate the total system safety, human factors, and health hazard assessments into continuous comprehensive evaluation of selected systems and facilities. The Chemical Research Development and Engineering Center (CRDEC) has mandated appropriate levels of system safety throughout the lifecycle of facility development for many reasons. These include ... 

Assessment. An analysis of the hazards present in this laboratory show the most significant hazard to be the release of vapor CSM from engineering controls and into the workplace. The significance of this hazard mandates further efforts in system safety in the form of a Preliminary Hazard List (PHL) and a Preliminary Hazard Analysis (PHA). The user must in this instance take an active role in the design review process. 

This article is a step in the direction we must all head toward and that is total system safety for facilities to reduce inherent hazards associated with their operation. 

Other possible preliminary safety analysis methods are concept safety review (CSR), critical examination of system safety (CE), concept hazard analysis (CHA), preliminary consequence analysis (PCA) and preliminary hazard analysis (PHA) (Wells et al., 1993). These methods are meant to be carried out from the time of the concept safety review until such time as reasonably firm process flow diagrams or early P I diagrams are available.

The following section looks at the processes and equipment commonly used in the compounding of epoxy adhesive systems. Since they can be utilized by either the formulator or the end user, there will be no strict division of the discussion by user. Hazards and safety issues related to these materials and processes are discussed somewhat in this chapter, but a more thorough discussion is found in Chap. 18. Test methods, quality control processes, and standards that are commonly used at the formulation level are addressed in Chaps. 19 and 20. 

In order to properly apply tlie system safety techniques to tlie design and operation of potentially hazardous tcclmologics, a series of questions regarding safety must be asked and answered.
