AN error by a map drawer has led to planning permission for several developments in Leith close to a ''hazardous installation'' being approved without advice from safety experts who required to be notified, it has emerged.

The official with the former Edinburgh District Council wrongly denoted Health and Safety Executive ''consultation zones'' when drawing up the Local Plan for the city's North East area in 1996.

The mistake came to light after a developer submitted plans to build almost 270 flats in Salamander Street in Leith.

Last May, a leisure development near the new berth of the former royal yacht Britannia encountered planning problems because of fears of fire from the nearby depot of Storage Services containing more than 1000 tonnes of ammonium nitrate.

It is classed as a hazardous substance because of the risk of an escape of toxic fumes in the event of decomposition in a major warehouse fire.

The HSE has made ''a holding objection'' to the leisure proposal for the old Corn Exchange building in Constitution Street.

The map error which led to a number of planning applications in the ''consultation area'' around Storage Services being approved without HSE's advice surfaces in a report to be presented to councillors next week.

The Salamander Street development application and one by a separate developer for 44 flats in Poplar Lane will also be put to councillors. Both are within the consultation distance of Storage Services.

In both cases, the HSE has said, that on the basis of the assessments, it was felt the risk of harm to people at the proposed developments from the hazardous substances was ''sufficiently high'' to justify advising against the granting of planning permission on safety grounds. Both applications are being recommended for refusal.

Dr George Hazel, director of city development, said the missed consultations were in the ''outer and middle rings'' of the consultation zone.

He indicated that Storage Services, part of the Russell Transport Group, was prepared to consider relocating the Leith operation but was evaluating whether such a move was feasible.
