38、ildings or public roads, the purpose of which is to protect the vessel from any damage, such as heating as a result of fire or mechanical damage; ? the distance between the vessel and an object outside the installation, which has to be protected from the effects of a gas release arising from normal
39、operation. These distances are measured from those points on a vessel from which in the normal course of operation a release of product may occur, e.g. vent point, fill connection, flanges or other mechanical joints. The safety distance is the distance, outside of which: ? in the case of flammable g
40、ases dangers through formation of an explosive atmosphere is eliminated, i.e. the lower explosive limit (LEL) is not exceeded; ? in the case of inert and oxidising gases, dangers from a lack of oxygen or enrichment are eliminated. The safety distances defined in annex B are based on experience and c
41、alculation of minor releases. They are given for inert fluids, oxidising fluids and flammable fluids. The maximum volumes/masses of product in the vessel considered are as follows: ? 175 m3 for inert fluids; ? 200 t for oxidising fluids (corresponding to approx. 175 m3 LOX); ? 5 t for liquid hydroge
42、n (corresponding to approx. 75 m3 LH2); and ? 50 t for other flammable fluids. For larger volumes/masses of products in the vessel the safety distances shall be determined by a specific hazard study. The safety distances are not intended to provide protection against catastrophic events or major rel
43、eases and these should be addressed by other means to reduce the frequency and/or consequences to an acceptable level. 3.7 gas release gas release may be due to operating conditions or malfunctions. Gas escape, caused by malfunctions, which can be reasonably excluded, are not taken into account Gas
44、release for operating reasons may be produced, for example; on ? vent lines; ? pressure release lines. Gas escape due to malfunctions which cannot be excluded may occur, for example, in the case of: ? overfilling; ? failure of fittings; ? loose connections; ? faulty operation; ? leakages. Licensed C

The training programme shall include: ? normal operating procedures; ? product and hazard identification; ? safe operating limits; ? emergency procedures; ? physical and chemical properties of the vessels conte

Appropriate warning signs regarding product and operational hazards and personnel protective equipment requirements should be displayed. Parts under pressure shall be disconnected only if they have been pr

Direct flame or intense heat shall never be used to raise the pressure or to de-ice frozen valves. Vessels shall be kept free from oil and grease; for cleanliness requirements see EN 12300. Valve outlets shall be kept clean, dry and free from contaminants. Vessels shall not be modified without proper authorisation. 5.2 Safety considerations In
