## Explanatory note

(This note is not part of the Regulations)
1 These Regulations amend the Control of Substances Hazardous to Health Regulations 1994 (“the principal Regulations”) by —
(a) substituting for Schedule 1 to the principal Regulations the Schedule set out in these Regulations which —
(i) adds eighteen new substances to the list of those substances which are assigned maximum exposure limits, while removing two others previously included,
(ii) amends the maximum exposure limits of thirteen other substances to take account of the adoption of a standard reference temperature and pressure, and
(iii) amends the maximum exposure limits of two other substances or groups of substances to take account of the adoption of the ISO/CEN Respirable Dust Convention; and
(b) making other minor amendments, including—
(i) the insertion of a new definition of “preparation” in regulation 2(1),
(ii) the amendment of regulation 13(1) to remove the reference to ethylene oxide as it can no longer be lawfully used as a fumigant, and
(iii) the amendment, deletion and insertion of several entries in Schedules 4, 5 and 6 to —
(aa) remove the need to monitor vapour given off from vessels at which an electrolytic chromium process is carried on, and to clarify the need for monitoring only when the process is being carried on,
(bb) remove the requirement for health surveillance for workers exposed tol-naphthylamine and its salts because it is no longer listed as carcinogenic, and
(cc) remove the reference to ethylene oxide (see (ii) above).
