Lift trucks rooms for battery charge

Sunday, 1 December 2013 PDF icon Lift trucks rooms for battery charge
Which production company does not have today a lift truck for the internal handling of bulky materials? Now it’s equipment present everywhere. Over the years, the electric-powered lift trucks have replaced older ones with diesel engines. Surely, the benefits for the environment, in terms of harmful emissions, were significant, but who have focused until now on the dangers of the rooms destined to the batteries recharge?

In-depth analysis on Risk Based Inspection

Friday, 1 November 2013 PDF icon In-depth analysis on Risk Based Inspection
In the newsletter of few months ago, we talked about the Risk Base Inspection. After many requests for more information on this topic, we’ll see below, in particular, what it is and what are the benefits of its application in terms of safety and costs. The Risk Based Inspection method (RBI) is used to optimize the frequency of inspections of facilities and equipment. This method was developed from the API-580 and API-581 issued by the American Petroleum Institute and it’s now being used for the management of inspections and maintenance in the chemical and petrochemical plant

The responsibilities in a system installed in a classified area

Tuesday, 1 October 2013 PDF icon The responsibilities in a system installed in a classified area
When we speak about an electrical installation in an area with presence of explosive atmosphere, we have to distinguish different responsibilities attributed to various actors with different skills. The main difference is between the responsibility on the equipment and the liability on the electrical system.

Long time for increased safety LEDs

Sunday, 1 September 2013 PDF icon Long time for increased safety LEDs
The drafters of the ATEX Directive 94/9/EC foresaw it in 1994: the technology would progress much faster than the legislative world, anchored in biblical times for the issuance of a new rule. In that time, they considered the possibility that the accredited laboratories have been able to certify, on their own, the products not prescribed by the regulations because of advanced technology. This proposal, after many vicissitudes, had been rendered virtually unenforceable and, today, we are paying the consequences.

Methods of protection in grain silos

Monday, 1 July 2013 PDF icon Methods of protection in grain silos
As we explained in the previous newsletter of June, the grain silos are a store or a place outside or inside a building, in which are stored food industry products, such as wheat, corn, rice or other similar products. We saw that dusts in suspension can create potentially explosive clouds. Therefore, all electrical and mechanical equipment must be designed, manufactured and maintained in accordance with the specific standards for explosion protection to avoid triggers.

The danger of explosion in grain silos

Saturday, 1 June 2013 PDF icon The danger of explosion in grain silos
The grain silos are a store or a place outside or inside a building, in which are stored food industry products, such as wheat, corn, rice or other similar products. All the loading operations are carried out generally with mechanical means such as pipes, conveyor belts, augers, etc.., through loading inlets placed in the upper part of the silo tower. Once stored, the products are taken from unloading hatchback doors placed in the lower part or they can be collected and transported by means of pneumatic or manual conveying systems. All products of the food industry are made up of carbon, hydrogen, nitrogen, sulfur, oxygen, etc.. Therefore, they are combustible and, consequently, able to causing fires and explosions.

The modular approach to certification according to directive 93/465/EEC

Wednesday, 1 May 2013 PDF icon The modular approach to certification according to directive 93/465/EEC
We never had occasion in this newsletter to speak about the Modular Approach of Directive 93/465/EEC concerning the various phases of the conformity assessment procedures and the rules for the affixing and use of the CE conformity marking, to be applied in the technical harmonization directives. This directive, issued in 1993 but still valid today, defines both the basic rules regarding the marking of CE products, both the basic rules concerning the procedures for assessing the conformity of a product.

The risk based inspection for explosion-protected equipment

Monday, 1 April 2013 PDF icon The risk based inspection for explosion-protected equipment
Since some time, the scientific and technical community is talking about the Risk Based Inspection, a process of analysis to define optimized plant plan maintenance, overcoming the classical approach of preventive maintenance at a fixed date. This methodology, which begins to have great applications in petrochemical sector, optimizes: the frequency of inspection; the methods of inspection; the extent of inspections depending on a risk.

A IECEx App to identify the certificated equipment

IECEx, the IEC system for the certification of equipment that can be used in environments with a potentially explosive atmosphere, has launched the first mobile application to show international certification for equipment used in explosive atmospheres. It’s available for Apple and Android devices for free and can be downloaded from Apple Store e Google Play.

The flame paths

Friday, 1 February 2013 PDF icon The flame paths
The most critical part of an ‘Ex d’ flameproof enclosure is the flame path. In order to understand what a flame path is and how it works we need to review briefly the principle on which is based the security of the ‘Ex d’ (flame proof) method of protection. This is the oldest method of protection that exists, the first used and still one of the safest because it is based on a very simple technology and, therefore, hardly fallible.
