Posted By Ken Taylor I'm sorry to see that you haven't received an answer to your questions. It may be that you are asking for more information than those of us who log on here have readily available. The Construction (Head Protection) Regulations 1989 have been in force for some 10 years and I seem to remember that adherance was somewhat gradual. It may be that either the HSE Construction National Interest Group (020 7556 2100) or the RoSPA Occupational Safety Division (0121 248 2000) will be able to produce the statistics you are seeking. Whilst those regulations are specifically limited in their application to certain types of workplace, it should be borne in mind that employers have a duty under the Management of Health and Safety at Work Regulations 1999 (formerly 1992) to assess workplace risks, record significant findings, establish controls, monitor, review, etc. It follows, therefore, that if you have a risk of persons being hit by falling objects this will be significant and unless you can remove this risk by other reasonably practicable means you will need by law to provide personal protection. The best arguement I can think of to persuade management of the need to require employees to wear hard hats is to hypothetically offer them the opportunity to wear one while a hammer is dropped onto their heads! If the need is this obvious, it will also be to the enforcing authority, the Courts and the legal advisors of the injured or their next of kin as they prepare to sue for considerable damages due to negligence.
