6 Requirements for Unsealing of Unprepared Equipment 20. In case it is impossible to fully prepare a piece of equipment according to the requirements set forth in Items 14 to 18 hereof as well as to check the preparedness of the equipment, the following additional measures ensuring occupational health and safety shall be applied while unsealing such equipment: Where hazardous chemical vapour or gas may release to the atmosphere while unsealing equipment, continuous air monitoring using portable explosive gas concentration analyzers shall be ensured at the site. In case the analyzer gets activated with the works in progress, work executors shall use the respiratory protecting equipment indicated in the permit; Covers, enclosures or shields resistant to chemical substances and protecting work executors against spill-overs, also directing the releases/spills to specific collection areas shall be used; Work executors shall wear chemical resistant clothing, panoramic closed type safety glasses, protective face shields, etc.; Where a spill-over with etching substances (acid or alkali) is possible during unsealing works, an emergency shower and an eye flushing station shall be located within the distance of not more than 50 meters. In case no stationary emergency washing equipment is available within the above mentioned distance, other means (e.g., portable flushing equipment, a vessel with water, water hose, etc.) shall be used. Before starting works, the functioning of washing equipment (if such is in good operating condition, not closed-up and has free (nonobstructed) access to it) shall be checked. 21. In case flammable substances are likely to release in the course of unsealing works, the below extra requirements shall be complied with: The hazard area shall be free from any sources of ignition (hot works in progress, machinery with internal combustion engines, temporary connections of el. equipment, etc.); Only the work means (including equipment, instruments and protective equipment) intended for potentially explosive atmospheres (as specified in the manufacturer s documentation) shall be used; Work tools shall be made from metal which does not generate sparks, or coated with nonferrous metal; Work executors shall wear work clothes from anti-static and fire-retardant fabric. Transfer of Equipment for Maintenance 22.

Before transporting unprepared equipment to the place of its preparation for maintenance, the equipment shall be prepared so that any leaks of hazardous substances during transportation are prevented (e.g., openings shall be blinded, equipment or its separate parts shall be tightly wrapped in covers resistant to hazardous substances, etc.). 24. Compliance with the requirement in Item 22 above shall be the responsibility of the head of the organizational unit which the equipment belongs to. Compliance with the requirement in Item 23 above shall be the responsibility of the contractor in charge of equipment delivery to the place of its preparation for maintenance. VI.

The permit shall be issued for each specific piece of equipment (e.g., tower, vessel, piping, etc.) separately. 34. The permit shall remain effective for the duration of one shift, however, for no longer than 12 hours. 35. The permit may be extended until the completion of the works indicated in it, however, for no longer than seven shifts from the date of issue of the permit, provided that the working conditions and nature of works remain the same. Extending of the work permit for the next following shift (e.g., extending of a permit issued for the period from 8 AM to 8 PM for the shift from 20 PM to 8 AM) shall be prohibited in case of change of responsible persons (work coordinator and /or work manager).

OCCUPATIONAL HEALTH AND SAFETY REQUIREMENTS DURING EXECUTION OF WORKS Equipment Unsealing 37. During unsealing of equipment (e.g., flanged connections), such shall be treated as pressurized items. 38. The flanges being unsealed shall be approached by a work executor with the wind blowing to his/her back. 39. An executor of unsealing works shall first of all loosen (by approx. three turns of the nut) the furthest from him/her bolt; only then the bolts adjacent to this bolt shall be loosened (with approx. two turns of the nut). 40. In case of failure to unseal the flanges upon loosening the bolts as per Item 40 hereof, such flanges shall be unsealed by expanding them. 41. Nuts shall not be completely turned off the bolts until flanges are unsealed in full. 42. In case some hazardous substances get released during unsealing works, or where pressure is detected inside the equipment, the unsealed point shall be immediately 7 9

8 resealed by tightening the bolts of flanged connections. The issuer of permit shall identify the causes of such hazards and shall authorize to resume unsealing works only upon the elimination of the causes of such hazards. 43. The blinds for process piping shall be selected, installed and removed in accordance with Process Equipment and Piping Blinding/De-blinding Manual BM-12.
