Days are numbered for the experimental near-miss

Virginia Purchon offers a health and safety warning to all science teachers. There was a time when science teachers did all sorts of interesting things with their pupils which are now frowned upon as risky. They let them look at their own blood through the microscope and culture bacteria in the laboratory. They electrified their pupils with the Van der Graaf generator and made mini-volcanoes with glycerine and potassium permanganate - and sometimes forgot to wear goggles.

Never mind the occasional small accident: it was all good fun and the laissez-faire teacher, or the over-experimental enthusiast usually got away with a near miss.

But times have changed, and teachers of science and technology in all schools - from nursery through to sixth-form colleges - need to be aware of the implications of recent health and safety regulations. These regulations, introduced in 1992 under the 1974 Health and Safety at Work Act, and in response to EU directives, have considerably tightened up and extended the legal side of workplace safety.

Since January 1993 every area of the workplace and every procedure - from the use of kitchen knives and cleaning fluids to leaking sinks - must be assessed for risks. What was implicit before must now (within reason) be recorded in writing, alongside any measures taken to reduce or eliminate the hazard.

Andy Piggott, previously a science advisory teacher in Richmond, now an education consultant advising on health and safety, has been doing science safety audits in schools in Bedfordshire. He has written science codes of practice for Richmond primary and secondary schools which he will introduce at the Association for Science Education's annual meeting next week. Emphasising that the key to good practice is management, he points out that the COSHH (Control of Substances Hazardous to Health) regulations form only part of all risk assessment.

Whereas the dangers of such substances as bleach, and what to do if you drink it, are covered by the Hazcards produced by CLEAPSE (Consortium of Local Education Authorities for the Provision of Science Equipment), what the cards do not cover is the chance of anyone doing so. That is where these new regulations come in.

In primary classrooms much safety practice is good organisation and awareness of child nature, but teachers still need guidance. To cover the tools and materials used in primary schools, Mr Piggott has developed Hazcards which advise on their appropriate and safe use, storage, and first aid.

Creating a health and safety culture among teachers and their pupils is an important aim. The highly publicised canoeing accident in Lyme Bay has alerted people to the tragic consequences of neglecting proper safety procedures. The manslaughter conviction in the subsequent court case underlined the employer's responsibility for safety. But everyone, not just the employer, has a "duty of care" in this respect.

Science and technology practical work is safe when everyone is vigilant, aware of potential hazards, and takes appropriate precautions. The same applies to the work of science and technology technicians. Whether old-style laboratories are healthy places to work in is another question.
