The presence of flammable and/or combustible substances in various industrial production processes generates in most cases potentially explosive atmospheres, which transforms a regular work environment into an explosion risk area, directly influencing the way in which equipment intended to be used in these areas is designed, installed and maintained. In areas where potentially explosive atmospheres may form due to the presence of flammable and/or combustible substances, technical equipment must be used whose casin...

Technical installations in explosive hazard environments have specially designed characteristics to ensure safe operation in such atmospheres. For safety reasons, it is essential to maintain the integrity of these special features throughout the entire lifespan of the installations through maintenance and inspection processes. In this operation it is necessary to use safety tools. These tools must be assessed and certified in accordance with the applicable requirements of the current legislation, regulated by Dire...

The protective clothing used by workers during the performance of work tasks is subject to the electrification process. The electrification process of protective clothing results in the generation of significant amounts of electrostatic charges both on the outer parts of the protective clothing and on the users' skin, as a result of specific mechanisms for generating electrostatic charges such as electrification by contact or induction. The formation and accumulation of electrostatic charges as a result of the ele...

A potentially explosive atmosphere exists when a mixture of air, gases, vapours, mists or dust combines in a way that can ignite under certain operating conditions. Hydrogen is the special gas in this context. Those who have knowledge of the properties and flammability of hydrogen will recognize that hazards due to explosive atmospheres must be assessed more and more frequently as the element is utilized, and, if necessary, appropriate protective measures must be taken. In this kind of atmosphere, special attentio...

An attack with a "improvised" explosive device (IED) is when someone uses a bomb and/or destructive device to cause damage, render someone helpless, harass, or divert attention. Terrorists, criminals, vandals, suicide bombers, and rebels all utilize IEDs. IEDs can take many different shapes because they are improvised; they can be as simple as a pipe bomb or as complex as a sophisticated weapon that can inflict significant damage and casualties. IEDs can be transported or carried in a car; they can also be deliver...

The removal and collection of dust particles from the air discharged into the atmosphere by industrial plants processing, transporting and storing dusty materials is an important objective for employers to prevent air pollution according to environmental legislation and employee safety regulations. Where the dust in question is flammable and may generate an explosive atmosphere, measures must be taken to prevent explosion and/or limit the effects of explosion. To this end, proper assessment of the risk of explosio...

The continuous development of human society from a technical-economic point of view is closely related to the increase in energy consumption. However, this implies the rapid depletion of existing fossil fuels and an accelerated increase in global pollution. At the moment, to counteract these impediments, one of the most important sources that can be used for the purpose of energy production, without having a negative impact on the environment, is hydrogen. Due to the fact that, when mixed with air, hydrogen can ge...

Many processes involving dusts, suspended or accumulated, have the potential to lead to fire, explosion or decomposition in the presence of oxygen and an ignition source. The risk of dust explosions increases as more and more products take the form of dusts or require the use of dusts during manufacture. In spite of extensive research and development to prevent and mitigate dust explosions in the process industries, this phenomenon continues to represent a constant hazard to industries including manufacturing, usi...

The processing, transport and storage of flammable materials in the form of dust generates an explosion risk due to the possibility of initiating potentially explosive atmospheres created by dust suspended in air with various ignition sources, some of which may be their own installations. As explosions can cause human casualties and severe property damage, the explosion risk assessment and the application of appropriate measures by manufacturers and users of installations to prevent the ignition of explosive atmos...
