NEW DESIGN FOR UDAL BRAKE SYSTEM

BUILT-IN SAFETY MACHINERY manufacturers can make a vital contribution to workplace safety, says Mr Bill Simpson, chairman of the Health and Safety Commission. "About 50 people are killed each year and 30,000 injured in machinery acci dents, " he said. "And safety by design should be the aim of every manufacturer if we are to cut this toll. " Mr Simpson spoke after visiting the Health and Safety Executive's stand at the 1978 Design Engineer ing Conference and Exhibition in Birmingham, where he was chairing a seminar.
