Selection, use, care and maintenance of personal protective equipment for preventing electrostatic risks in hazardous areas (explosion risks)

This Technical Report sets out guidance for the selection, use, care and maintenance of clothing and related items of personal protective equipment designed to prevent hazards caused by static electricity in hazardous areas.
Static electricity should not be confused with mains supply electricity, or other forms of electric current; the requirements for protection against static electricity are different to the requirements for protection against hazards associated with electric current. Protection against electrostatic risks should not be confused with protection against electric arc; the former is concerned with electrical properties and the latter is concerned with heat, flame and projectile protection.
Directive 89/686/EEC requires that PPE intended for use in explosive atmospheres must be so designed and manufactured that it cannot be the source of an electric, electrostatic or impact-induced arc or spark likely to cause an explosive mixture to ignite. Whereas this Technical Report addresses electrostatic ignition risks, it does not address other possible sources of ignition. Nevertheless, other possible sources of ignition are required to be considered when certifying PPE to the requirements of Directive 89/686/EEC.
NOTE   EN 13463-1 gives guidance on assessing possible ignition sources in non-electrical equipment that may be used for some items of PPE.

Introduction
European Standards for personal protective equipment (PPE) are developed to ensure compliance
with the European Directive 89/686/EEC. Since the primary aim of this directive is to guarantee a free
market in the European Union, these standards are made to meet the needs for a common set of
safety requirements and test methods.
The actual use of PPE is not covered by this directive, nor by related standards.
This Technical Report has been developed to meet the needs for a document on selection, use, care
and maintenance. Regulations on health and safety are based on Directive 89/686/EEC, giving
minimum requirements on the selection and use of PPE
