Blabo safety

  1. 1. BLABO safety BLABO® safety
  2. 2. BLABO safety BLABO and safety • Oreco never compromises on safety • Our mission is to provide the safest system in the world • Design, construction and cleaning process comply with: • European directives (ATEX, Machines Directive, Pressure equipment directive etc.) • Regional/international standards like CSA/UL (upon request) • Other national regulations that may apply
  3. 3. BLABO safety ATEX directive ATEX consists of two European directives: Directive 1999/92/EC • Also known as the 'ATEX Workplace Directive’. • Deals with the safety and health of workers, potentially at risk from exposure to explosive atmosphere. • Has been in force from 30th of June 2003. • Deadline for enforcement is 30th of June 2006. Directive 94/9/EC • Known as the 'ATEX Equipment Directive’. • Deals with equipment intended for use in potentially explosive atmosphere. • Has also been in force since 30th of June 2003.
  4. 4. BLABO safety What does ATEX mean for tank cleaning? • Main purpose is to minimise, or completely eliminate, the risks associated with explosive areas and to limit the harmful effects in case of an explosion. • This means that both service providers, offering tank cleaning services, and tank owners must prepare and carry out procedures for performing safe work in areas/zones with potentially explosive atmospheres. • Only ATEX approved equipment can be used for tank cleaning in specified zones.

  6. 6. BLABO safety Inside the tank and on the roof 1 Tank roof • Tank roof is zone 1 area. • All Oreco ‘tank roof equipment’ with a potential ignition source is category I approved according to ATEX. 2 Cold tapping tool - SafeTap • Designed in accordance with the European standard EN 1343-1. • Is certified as category 1/2 equipment. • Tested at approved by notified body. 3 Distribution header • Approved for zone 1. 5 Tank blanketing • Inerting eliminates the risk of ignition. • Inerting is covered by ATEX 1999/92/EC. • Tank owners’ or service providers’ responsibility to ensure inert atmosphere. 4 Nozzles • Certified as category I equipment, according ATEX 94/97EC. Approved by notified body. • Operation of nozzles is covered by ATEX 1999/92/EC for work in potentially explosive atmospheres. 1 · 2 · 3 5 4 Tank roof Sump Nozzle Inerting BLABO
  7. 7. BLABO safety BLABO process modules 7 Pressure piping • Constructed in accordance with EU directive 97/23/EC for pressurized equipment. • Non destructive test (EN 13480-4). • Unique tracking number and material certificates. 6 Piping • Has no potential ignition source and do therefore not fall within ATEX. • User must ensure piping is safely earthed. • BLABO’s Victaulic piping and couplings are clam-fitted to ensure 100% conductivity. 8 Electronic cabinets Re-circulation & Separation modules • Recirculation and Separation modules. • Designed and built according to EN 50016 (Electrical apparatus for potentially explosive atmospheres - pressurized apparatus ‘p’). • Verified and tested according to ATEX directive 94/9/EC. 10 Gas detectors • Approved as at lease category II equipment. • Fulfil requirements in standards EN 50057 and EN 50058. 9 Electronic cabinets Suction & Skimming modules • Designed and built according to EN 50018 (Electrical apparatus for potentially explosive atmospheres - flameproof enclosure ‘d’). • Verified and tested according to ATEX directive 94/9/EC.
  8. 8. BLABO safety BLABO process and BLABO system in general 11 Temperature • Insulated pipes, valves and flange connections. • Surface temperature does not exceed 55˚C. 12 All moving parts • Moving parts protected by covers. • Cannot be opened without tools. • Risk assessed according to EU directive 98/37/EC for machinery safety. 13 Electrical equipment • As minimum zone I approved. • Constructed in accordance with EN 50014 (requirements for electrical apparatus in explosive atmospheres). 14 Monitoring and Auto-shut down • Continuous monitoring. • Built-in warning systems. • Monitoring of oxygen level. • Shut-down of process if oxygen level exceeds 8%. • Shut-down of process if LEL exceeds 20%. 15 Closed loop • Tank cleaning media runs in a closed circuit. • Operators never get into contact with the media. 16 Non-man entry • Risk of sparks due to high activity inside tank is eliminated.
  9. 9. BLABO safety Other personal safety measures 19 Other personal safety and health issues • No staff is exposed to toxic or carcinogenic substances. • No respiratory problems or oxygen deficiency. • No injuries caused by inadequate lightning or structural tank failure. • Containers are equipped with gas detectors. • Insulated pipes, valves and flanges. • Etc. 17 Training • Thorough training by Oreco in operating the system. • Thorough training in safety procedures. 18 Non-man entry • No personnel inside tank during cleaning process.
