                                TRADING UPDATE

Halma, the leading safety and environmental technology group issued a trading
update today, 25 October 2001. Halma issues trading updates each April and
October, approximately two months ahead of its full year and interim results
announcements.

Stephen O'Shea, Chief Executive, comments:

'In line with the AGM statement made on 1 August 2001, the Group's performance
and pattern of trading for the first five months of the year have remained
good. Indeed, sales increases in the UK and Europe have compensated for some
reduction in our US markets.

'With around a third of Group sales and profits emanating from the US, it was
inevitable that the recent events would impede the delivery of certain
existing orders and have some impact on our half year figures, which are now
likely to be at a similar level to those reported last year.

'We continue with our proven strategy of developing unique intellectual assets
and marketing the products that result to existing and to new customers. In
this way we are able to build and sustain dominant global positions in our
carefully chosen sectors. We remain cash generative, debt free and well
positioned for further growth.'
