The Herald has added another really useful link for non-blokey-bloke people, you know the ones who aren't quite as technical as the blokey-bloke people. They tend to have fairly basic needs and menial tasks to perform. Say no more. Today we bring you a handy guide to Hazchem codes. So if you see these on buildings near your house, you'll know what to fear.
For example Willesden Police Station displays the Hazchem code "2W". The 2 indicates fine spray, and the W determines the kind of protective clothing to be worn by emergency services to deal with it in the event of accidents.
The BT telephone exchange in Harlesden Road has a Hazchem sign on the door, but no code. It is in a filthy condition. In its heyday 200 operators were employed switching calls. Now it is totally automatic and engineers have to make an appointment to get in if they need access.
[Herald links like these are thought to be useful for non-blokey people, who do not know how to save their own useful links. Ed.]
