3. Riskassessement • General Observations • Theevaluationoftherisks to thesafetyandhealthofworkers(article 6, 3 (a) Framework directive) should: Following the general principles of prevention: 1.º Once identified the ATEX risk, it should be avoided; 2.º The risks that can not be avoided must be assessed.

5. Riskassessement • General Observations Which methodologies can be applied to perform a risk assessment in a potentially explosive atmosphere? Guide to goodpractice for implementingtheEuropeanParliamentandCouncilDirective 1999/92/EC • The evaluation shall operate in methodologies and procedures based on: • Regulations(legal); • Standards(NP, EN, ISO, ...); • Guides/Guidancedocuments • Manuals of machinery and equipment; • Safety data sheets; • Questionnaires/interactivetools; • Cheklists; • Sectoralpreventionmanuals; • …Qualitative, quantitative or semi-quantitative methodologies, since adequate, consistent and substantiated.

8. Riskassessementofexplosive atmosferas • ImportantConsiderations Following the usual basic principles of prevention, the RA should include: • Identification of the hazards • Determination the possibility of formation of a hazardous ATEX • Identification and analysis of possible sources of ignition • Determination the probability of presence and activation of ignition sources • Estimation of the possible effects of the explosion • Estimation/valuation of the ATEX risk • Definition of measures to eliminate or reduce the risk • Updatingandreview Technical Note Prevention - 876 NT – Assessment of specific risk from explosive atmospheres National Institute of Safety and Hygiene Spain Turkey, 26 May 2014 Vanda Caramelo

9. Riskassessementofexplosive atmosferas • ImportantConsiderations • Identification of the hazards • This stage involves the identification and analysis of risk explosion, either by formation of a possible ATEX or presence/activation of ignition sources (electric-electrostatic, mechanical, chemical origin); • All substances and products flammable should be considered. • Determination the possibility of formation of a hazardous ATEX • The key point to determine the possibility of ATEX formation is the knowledge of the parameters: inflammabilityandexplosivityofthe products involved in the various stages of the process production (raw materials, intermediates, end products, ...); • The possibility of forming an ATEX is determined by the degree of dispersion and concentration of the flammable substance or product. This calculation is based on the frequency and duration with which occurs ignitable mixture with the air. Turkey, 26 May 2014 Vanda Caramelo

10. Riskassessementofexplosive atmosferas • ImportantConsiderations • Identification and analysis of possible sources of ignition We must assess all sources of ignition that may appear in areas where ATEX can be formed. These sources of ignition can be fixed (equipment and fixed equipment in areas of risk) or may be introduced in the areas of risk because other activities developed. • Determination the probability of presence and activation of ignition sources • Estimation of the possible effects of the explosion • When studying the consequences or severity of the effects of a possible explosion, it must be taken into account, among other things: • Extent and nature of damage (personal, material, environmental, etc..); • Effectiveness of prevention and protection measures existing; • Reliability of security systems; • Possibility of existing security measures being neutralized; • Possible domino effect if secondary explosions occur. Turkey, 26 May 2014 Vanda Caramelo

11. Riskassessementofexplosive atmosferas • ImportantConsiderations • Estimation/valuation of the ATEX risk • Matrix combining the probability and duration of ATEX (parameter estimated from the classification of the risk areas) and the probability of presence and activation of the ignition source; • Matrix that represents the product of the probability of the risk to the severity of the consequences: • Slight Hazard: No specific action is required urgently; • Medium risk: should establish and adopt, in a period fixed, measures to reduce the risk of explosion; • High risk: As a priority, it requires a immediate action; • Very high risk: You should not start or continue the work until the risk is reduced. the situation requires an urgent correction absolute.

12. Riskassessementofexplosive atmosferas • ImportantConsiderations • Definition of measures to eliminate or reduce the risk • Technicalmeasures: • Prevent the formation of hazardous explosive atmospheres; • • Avoid the ignition of hazardous explosive atmospheres; • • Mitigate the effects of explosions so as to ensure the health and safety of workers . • Organisationalmeasures: • Operatinginstructions; • Workercompetence; • Training ofworkers; • Workersupervision; • Permit-to-worksystem; • Maintenance; • Inspectionandchecking; • Markingofhazardousplaces.

13. Riskassessementofexplosive atmosferas • ImportantConsiderations • Updatingandreview • Risk assessment must be kept current and reviewed periodically, especially before any new activity and/or process, or before changes and/or amendments in any proceedings or process existing; • RA has to be documented and available to the labor authority. • The result of this assessment and report will be part of the explosion protection document, which will be developed before work begins and always revised when it made​​, extensions or major changes in place of work, work equipment or organization job. The complexity of this type of document is extremely variable, depending on the number of ATEX zones covered, the existing / identified risks, the specific characteristics of each site / task, among others aspects.

14. Riskassessementofexplosive Summarizing • Summarizing… • Risk assessment is the essential first step in the prevention of occupational accidents and ill health; • There are many risk assessment tools and methodologies available to help enterprises and organisations assess their health and safety risks; • The choice of method will depend on workplace conditions (the number of workers, the type of work activities and equipment, the particular features of the workplace and any specific risks).
