Design manual, safety

The product of this 8 year systematic study was the publication of the safety design manual entitled, "Structvires to Resist the Effects of Accidental Explosions" (Army s Publication TM5-1300). An outline of studies leading to publication of this manual is shown in Fig 1. The manual contains procedures, charts, and tables required to establish the environment of an explosion and its output in terms of blast and fragments. The relations are presented in such a manner that the type of protective structure may be selected, analyzed, and designed to provide a safe level of protection for personnel, equipment, and for separation of potentially mass detonating materials. 

In my introductory portion of this paper I mentioned that in the 60 s we developed a safety design manual (TM5-1300) which deals primarily with the design of protective structures located in the high pressure region close-in to a detonation. 

Design basics for the use of FRP profiles in civil engineering applications are provided in ASCE (1984) and EUROCOMP (1996), but these two documents do not have model code-like status. Additionally, there exist design manuals published by the manufacturers of pultruded FRP profiles, e.g. FiberlineComposites (2003). Beside the design concept, all the necessary material parameters and associated material safety factors are given in these manuals. 

This book is not a design manual. We provide examples to illustrate the points under discussion and not to serve collectively as a coordinated design. Safety factors and... 

In 1990 a Standard and Advice Note on Road Safety Audit were introduced as part of the Design Manual for Roads and Bridges (DMRB). This made Road Safety Audit mandatory on trunk roads and motorway schemes from 1991 onwards.

Transportation Association of Canada (TAC) http //dev.tac-atc.ca/english/index.cfm (accessed September 13, 2010). TAC promotes knowledge on technical guidelines and best practices for roadways and urban transportation systems. Publishes manuals and handbooks on design, construction, safety, and operations. 

A battleshort is a design feature that provides the capability to short or bypass certain safety features in a system to ensure completion of a mission without interruption that would normally result from the triggering of a safety interlock. Battleshorts are typically manual switches that bypass designed-in safety interlocks during emergency situations a battleshort is a un-safety design feature. 

As listed in Table 1, Washington State does not have a formal 3R policy but does have Modified Design Level, which preserves and improves existing roadway geometries, safety and operational elements. Chapter 1130 of the Washington State design manual provides the design criteria for this type of improvement. 

Safety-related systems can broadly be divided into two types control systems and protection systems, although not all control systems will necessarily be designated as safety-related systems. It should be noted that a person could be part of a safety-related system (e.g. a manually deactivated ESD system) [Bell 91]. 

Manual safety actions should be facilitated by the design and layout of the control room. All controls, displays and alarms necessary for safe operation, reactor shutdown and removal of residual heat from the reactor as well as for containment system functions should be readily available and should present information to the operator in a clear manner. 

The National Roads Authority (NRA) in Ireland fully revised the Road Safety Audit standard (HD 19/12) within the Irish Design Manual for Roads and Bridges in 2012 (NRA, 2012). Many local road authorities in the country carry out Road Safety Audits on local roads, and the Department of Transport in Ireland requires that local road authorities bidding for safety funding for roads schemes undertake Road Safety Audits on such schemes in line with the requirements in the standard. 

The Road Safety Audit guidelines have two companion manuals Manual de Prdcticas Inadecuadas (MPI, Bad Practices Manual) and the Manual de Diseno Vial Seguro Safe Road Design Manual). The MPI identifies ten types of bad practice that should be avoided. 

It is obvious that the best designed facility is no better than the attention that is paid to safety. The latter is not considered once and forgotten. Rather, it is an ongoing activity that requires constant attention to every conceivable hazard that might be encountered. Because of its importance, safety, particularly at low temperatures, has received a large focus in the literature with its own safety manual prepared by NIST as well as by the British Cryogenics Council.

The amount of process plant that can be defined accurately as automatic is relatively small, and manual intervention is often involved at some stage. The relevant design criteria are therefore often IM/12 or IM/18. In practice, fully automatic burner controllers tested and certified by British Gas are available that comply with the requirements of BS 5885. Although these have features which may not be applicable to non-automatic plant, it may be more appropriate to use such a controller, particularly as its safety is well proven. It may also be less expensive than buying and installing separate timers, relays, etc. For some processes (for example, those that do not need and cannot tolerate a long purge) such controllers may not be appropriate.
