MR. RAMEL, ALSO OF FRANCE, SHOWED A NUMBER OF SLIDES RELATED TO RESEARCH ON FUME GENERATION AND POLLUTION TOLERANCE. DR. RUCKLI OF SWITZERLAND, WHERE TUNNELS ARE USUALLY LONG, DISCUSSED THE PROBLEM OF TUNNEL FIRES, BOTH PREVENTION AND EXTINGUISHING METHODS. SUBSEQUENT SPEAKERS INCLUDED: (1) DR.

AFTER A SUMMARY OF THE DISCUSSIONS ON ROAD TUNNELS, HIGHLIGHTS OF A REPORT PREPARED BY THE TECHNICAL COMMITTEE ON SLIPPERINESS WAS PRESENTED BY THE CHAIRMAN, M. PARGUET OF FRANCE. DISCUSSIONS OF MEASUREMENTS OF SLIPPERINESS, BRAKING DISTANCE AND SKID RESISTANCE WERE GIVEN BY MR. ICHIHARA OF JAPAN, MR. LYONS OF GREAT BRITAIN AND MR. SCHULTZ OF GERMANY. DR.
