Investing in safety is good for business
09 November 2004 - EJA
The recent recessionary climate in UK manufacturing industry has meant that many companies have cut costs and investment to the bone in order to remain profitable. The ramifications of this policy are felt at all levels of manufacturing even in areas one would least expect such as plant floor safety. This is undoubtedly short-sighted, as the cost of an accident, in terms of legal action, possible fine, and lost production will greatly outweigh any costs resulting from not using safety equipment. However, companies not investing in safety equipment can still incur disastrous costs even when accidents do not occur.

Investing in safety equipment makes good economic sense
24 January 2002 - EJA
The arguments to companies who are holding back from investing in safety equipment fall into two major categories: economic and ethical. Although, on first reading, these would seem to be at opposite ends of the spectrum, they are in fact closely linked. They are linked because safety always pays: a safe machine is unlikely to be shut down by inspectors, or cause costly interruptions to production as a result of an accident.
