Process owners should also consider alarm-system guidance provided in other standards and practices. For example, the Engineered Equipment and Materials Users Association (EEMUA), Health Safety Executive (HSE), and The International Society of Automation (ISA) have developed extensive guidance on alarm management. Design of alarm systems should consider ISA 18.1-1979, ANSI/ISA 18.2-2009, ISA RP 60.3-1985, ISA RP 60.6-1984, EEMUA 191-2007, ANSI/IEEE-845-1999, ANSI/IEEE-Std 1023-2004, IEEE-1289-1998 and NUREG-0700 Rev 2-2002. 

Where the equipment emits noise fluctuating in a more complicated manner, the equivalent continuous sound level can be calculated according to the method given in the Engineering Equipment and Materials Users Association (EEMUA) 140 (EEMUA 1985). 

Human flictors The display/log presentations have lot of bearing on operator action. Alarm presentation is extremely important so that many human errors can be avoided. Recommendations by the Engineering Equipment and Materials Users Associations (EEMUAs) are very useful here. A typical recommendation of EEMUA in connection with alarm system has been depicted in Fig. lV/1.5.1-2. 

Much of the following description has been synthesized from the Engineering Equipment and Materials Users Association (EEMUA) guide to alarm systans, EEMUA 191 2007 (EEMUA, 2007). The EEMUA guide provides a comprehensive description of the many factors influencing the design of an alarm system. EEMUA 191 2007 points out that alarm systems shoul ...

In-line silencers can reduce the noise associated with fluid flow. Silencers can either contain baffles and chambers, or porous material such as stainless steel wool. Guidance having to do with the design of silencers is provided by the Engineering and Equipment Users Association (EEMUA 1988).

The lack of prescription in the legislation is meant to be offset by the provision of comprehensive guidance and the setting of benchmark standards by bodies such as the Health and Safety Commission/Health and Safety Executive (HSC/HSE) and the British Standards Institution (BSI). Trade associations and other similar organisations have an important role in this respect, and guidance material published by bodies such as Electrical Equipment Manufacturers and Users Association (EEMUA), the Institution of Electrical Engineers (lEE), the Electrical Contractors Association (ECA) and Electrical Contractors Association of Scotland (SELECT) is extremely useful.
