In recent editions it has been in two volumes, volume 1 being individual compounds and hazardous reactions, volume 2 being ...
Chemical hazards are usually classified separately from biological hazards (biohazards). Chemical hazards are classified into groups that include asphyxiants, corrosives, irritants, sensitizers, carcinogens, mutagens, teratogens, reactants, and flammables.

GCSE Bitesize was launched in January 1998, covering seven subjects. For each subject, a one- or two-hour long TV programme would be broadcast overnight in the BBC Learning Zone block, and supporting material was available in books and on the BBC website. At the time, only around 9% of UK households had access to the internet at home.
Triple Award Science, commonly referred to as Triple Science, results in three separate GCSEs in Biology, Chemistry and Physics and provide the broadest coverage of the main three science subjects. The qualifications are offered by the five main awarding bodies in England; AQA, Edexcel, OCR, CIE and Eduqas.
The National Risk Register divides risks into four main categories: natural hazards, major accidents, societal risks, and malicious attacks. It evaluates a number of risks under each of these headings, rated by relative impact and likelihood, and discusses the measures currently in place to deal with each of these.
