SANS 10108 The Classification Of Hazardous Locations And The Pdf [REPACK]
What is SANS 10108 and Why is it Important for Electrical Safety?
SANS 10108 is a South African national standard that specifies the criteria for the classification of hazardous locations and the selection of apparatus for use in such locations. Hazardous locations are areas where flammable gases, vapours, liquids, dusts or fibres may be present in quantities that could cause a fire or explosion if ignited by an electrical spark or other source of ignition. SANS 10108 provides guidance on how to identify and classify such locations according to the nature and frequency of the hazard, and how to select appropriate electrical equipment that is designed and certified to prevent ignition in these environments.
SANS 10108 The Classification Of Hazardous Locations And The Pdf
Electrical safety is a vital aspect of any industrial, commercial or residential installation, especially where hazardous substances are involved. Ignoring or violating the requirements of SANS 10108 could result in serious consequences, such as injury, death, property damage, legal liability and environmental harm. Therefore, it is essential that anyone who is involved in the design, installation, inspection, maintenance or operation of electrical equipment in hazardous locations is familiar with and complies with SANS 10108.
How to Access SANS 10108?
SANS 10108 is published by the South African Bureau of Standards (SABS), which is the national body responsible for developing and maintaining standards in various fields. SANS 10108 is available for purchase from the SABS online store[^2^] or from authorized distributors. Alternatively, you can access a free PDF version of SANS 10108 from the Department of Labour website[^1^], which incorporates it into the Electrical Installation Regulations, 2009. However, this version may not be updated or complete, so it is advisable to refer to the latest edition from the SABS.
What are the Main Contents of SANS 10108?
SANS 10108 consists of nine chapters and four annexes that cover the following topics:
Chapter 1: General - This chapter defines terms and symbols used in the standard, outlines its scope and application, and references other relevant standards.
Chapter 2: Hazardous substances - This chapter describes the properties and characteristics of flammable gases, vapours, liquids, dusts and fibres that may create hazardous locations.
Chapter 3: Classification of hazardous locations - This chapter explains how to classify hazardous locations into zones based on the likelihood and duration of the presence of a flammable atmosphere. It also provides examples and diagrams of typical hazardous locations in various industries.
Chapter 4: Selection of apparatus - This chapter specifies the requirements for selecting electrical equipment for use in hazardous locations, based on their type of protection, temperature class, group and category. It also gives guidance on marking, labelling and documentation of such equipment.
Chapter 5: Installation requirements - This chapter details the general rules and precautions for installing electrical equipment in hazardous locations, such as wiring methods, earthing, bonding, segregation, sealing and ventilation.
Chapter 6: Inspection and maintenance - This chapter outlines the procedures and frequency for inspecting and maintaining electrical equipment in hazardous locations, as well as the records and reports that should be kept.
Chapter 7: Special situations - This chapter covers some specific situations that require special attention or deviation from the general rules, such as intrinsically safe systems, increased safety systems, pressurized enclosures, mobile equipment and temporary installations.
Chapter 8: Verification - This chapter describes the methods and criteria for verifying the compliance of electrical equipment with SANS 10108, such as testing, certification and auditing.
Chapter 9: Information exchange - This chapter specifies the information that should be exchanged between different parties involved in the design, installation, inspection and maintenance of electrical equipment in hazardous locations.
Annex A: Examples of classification - This annex provides some illustrative examples of how to apply the classification principles of SANS 10108 to various scenarios.
Annex B: Typical apparatus data sheets - This annex provides some sample data sheets for different types of electrical equipment that may be used in hazardous locations. c481cea774
