This series of articles is intended to provide clarity and answer the respective frequently asked questions.<\/p>\n<p>Today&#8217;s article &#8220;Frequently Asked Questions&#8221; is about explosion protection.

The occurrence of hazardous explosive mixtures must be assessed <u>without<\/u>the inclusion of protective measures.<\/p>\n<p>I.e. even if no hazardous areas (Ex zones) are defined in a plant due to (explosion) protection measures (technical ventilation, inerting &#8230;) which prevent the formation of GGE, this plant is an Ex plant and these protection measures must be checked accordingly.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;Are there quantity thresholds for flammable liquids up to which explosion protection measures are not prescribed?&#8221; tab_id=&#8221;mengenschwellenba48-253b&#8221;][vc_column_text]When handling hazardous substances, a risk assessment (GBU) must always be carried out. The Ordinance on Hazardous Substances (GefStoffV) does not mention &#8220;de minimis limits&#8221;. In this GBU, however, it can be concluded on the basis of TRGS 510 &#8220;Storage of hazardous substances in portable containers&#8221; that, depending on the classification of the hazardous substance (H-phrases), no special protective measures that go beyond the general requirements of a hazardous substance storage facility are necessary.<\/p>\n<p>This is the case, for example, for extremely flammable liquids (H224) in quantities \u2264 10 kg. For \u2264 200 kg, extended requirements for the hazardous substance storage are still sufficient. However, for &gt; 200 kg, special protective measures (explosion protection) must be implemented.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;Do employees need additional training to work in potentially explosive atmospheres?&#8221; tab_id=&#8221;schulungenba48-253b&#8221;][vc_column_text]Yes, according to \u00a714 (2) GefStoffV, employees must be instructed verbally about all hazards that occur and the corresponding protective measures, this also includes hazards due to explosions. The instruction can take place within the framework of the occupational health and safety instruction.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;Does the explosion protection document need to be updated regularly?&#8221; tab_id=&#8221;ex-schutz-dokumentba48-253b&#8221;][vc_column_text]The risk assessment for hazards from explosions must be presented in the explosion protection document. All risk assessments must be reviewed regularly in accordance with \u00a76(10) GefStoffV and updated immediately in the event of significant changes.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;Where are the inspection intervals for explosion-protected systems specified?&#8221; tab_id=&#8221;prueffristenba48-253b&#8221;][vc_column_text]For systems in which hazardous explosive atmospheres can occur, the minimum inspection intervals are specified in the <a href=\"https:\/\/www.bgn-branchenwissen.de\/daten\/gv\/betrsichv\/anh2.htm\" target=\"_blank\" rel=\"noopener\">Ordinance on Industrial Safety and Health (BetrSichV) Annex 2 Section 3 No. 5.<\/a> This BetrSichV has been in force since 2015. For installations that were commissioned before 1 June 2012, a transitional period applied until 01 June 2018, by which time these installations had to be inspected on a recurring basis.<\/p>\n<p>In the case of hazardous explosive mixtures, test intervals are to be specified in the GBU; they are not bound to the test intervals of the BetrSichV, although these are generally useful as a reference value.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;Does the explosion protection document replace the GBU according to BetrSichV?&#8221; tab_id=&#8221;gefaehrdungsbeurteilungba48-253b&#8221;][vc_column_text]No, the explosion protection document is the risk assessment (GBU) according to \u00a76(9) GefStoffV and only considers hazards due to explosions. The GBU according to \u00a73 BetrSichV considers all hazards that can occur during use with work equipment and therefore includes other hazards. However, reference can be made to the explosion protection document for the item &#8220;Hazards due to explosions&#8221;.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;Is an Ex-Zone Plan mandatory?&#8221; tab_id=&#8221;ex-zonen-planba48-253b&#8221;][vc_column_text]No, it is not mandatory to graphically illustrate the Ex zones identified in the explosion protection document in a plan. However, it is a very helpful means of displaying the Ex zones clearly and at a glance, thus making it easier to implement them in the operational process.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;Is it better to prepare a single explosion protection document or a partial document for each plant and a superordinate explosion protection document for all of them?&#8221; tab_id=&#8221;teildokument-gesamtdokumentba48-253b&#8221;][vc_column_text]It is basically up to the employer how he wants to organise this. Here, too, there are no specifications. Depending on the size of the enterprise, it may be clearer to consider parts of the site in a partial explosion protection document and to draw up a superordinate document for all partial documents in which measures and basic principles are defined that apply to all.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;Are there any specifications for the design of EI&amp;C technology for explosion protection?&#8221; tab_id=&#8221;emsr-technik-ex-schutzba48-253b&#8221;][vc_column_text]If measurement and control technology is used to monitor explosion protection measures, it must be carried out in accordance with TRGS 725. TRGS 725 thus replaces the former classification of EMSR technology according to VDI 2180 Part 6.[\/vc_column_text][\/vc_tta_section][\/vc_tta_accordion]<div class=\"grve-element grve-hr grve-space-divider\" style=\"\"><\/div>[\/vc_column][\/vc_row][vc_row bg_type=&#8221;color&#8221; bg_color=&#8221;#0070b9&#8243; font_color=&#8221;#ffffff&#8221;][vc_column width=&#8221;1\/2&#8243;]<div class=\"grve-element grve-hr grve-space-divider\" style=\"\"><\/div>[vc_column_text]\n<h3><span style=\"color: #ffffff;\">Arrange a free initial consultation<\/span><\/h3>\n<p><span style=\"color: #ffffff;\">We will be happy to answer any further questions in our free initial consultation.
