Safe teaching

Chesterfield College has installed a new noise measurement device in its workshops. The unit, manufactured by Pulsar Instruments, will enable safe teaching without ear protection but give immediate warnings when ear muffs must be worn.

Paul Lowry, health and safety officer at the college, said: "Until now, we have had to rely on random noise testings in areas such as auto workshops, engineering, silversmith and brick workshops. PulsarSafeEar is really simple, accurate and visual.

As soon as noise in the workshop goes over the legal limit, it flashes on the wall and teachers and students can immediately see they need to wear protection."
