The Regulations apply to establishments (as defined in regulation 2(1)) where dangerous substances are present in quantities equal to or exceeding those specified in column 2 of Parts 2 or 3 of Schedule 1, except that regulations 7 to 14 apply to establishments where such substances are present in quantities equal to or exceeding those specified in column 3 of those Parts (regulation 3(1)). The Regulations do not apply in the cases specified in regulation 3(2).
The competent authority for the purposes of the Regulations is the Health and Safety Executive and the Environment Agency acting jointly, except that in Scotland it is the Health and Safety Executive and the Scottish Environment Protection Agency acting jointly.
The Regulations—
(a) impose a duty on the operator of an establishment to take all measures necessary to prevent major accidents and limit their consequences for persons and the environment (regulation 4);

(e) require the operator to review and revise the safety report in specified circumstances (regulation 8);
(f) require the operator to prepare an on-site emergency plan for specified purposes and containing specified information (regulation 9 and Schedule 5);
(g) require, subject to any exemption that may be granted by the competent authority, the local authority to prepare an off-site emergency plan for specified purposes and containing specified information and require the operator to supply to the local authority the information necessary to enable the plan to be prepared (regulation 10 and Schedule 5);
(h) require on-site and off-site emergency plans to be reviewed, tested and implemented (regulations 11 and 12), and empower the local authority to charge the operator a fee for preparing, reviewing and testing the off-site emergency plan (regulation 13);
(i) require the operator to provide, after consulting the local authority, specified information to specified persons at specified times and to make that information publicly available (regulation 14 and Schedule 6);
(j) require the operator to demonstrate to the competent authority that he has taken all measures necessary to comply with the Regulations (regulation 15(1));
(k) require the operator to provide, when requested to do so by the competent authority, information to the authority for specified purposes (regulation 15(2));
(l) require the operator to notify major accidents to the competent authority (regulation 15(3) and (4));
(m) require the operator to provide information to, and to co-operate with, other establishments in a group designated by the competent authority (regulation 16);
(n) impose functions on the competent authority with respect to—
(i) its consideration of the safety report sent by the operator (regulation 17);
(ii) prohibiting the operation of an establishment (regulation 18);
(iii) inspections and investigations (regulation 19);
(iv) enforcement (regulation 20); and
(v) the provision of information (regulation 21 and Schedules 7 and 8);
(o) provide for fees to be payable by the operator to the Health and Safety Executive in relation to the performance of specified functions of the Executive or competent authority (regulation 22);
(p) amend the Petroleum Consolidation Act 1928, the Petroleum-Spirit (Motor Vehicles etc.) Regulations 1929 and the Petroleum-Spirit (Plastic Containers) Regulations 1982 so as to disapply those Regulations to establishments subject to these Regulations and to sites subject to the Notification of Installations Handling Hazardous Substances Regulations 1982 (regulation 23);
(q) revoke the Control of Industrial Major Accident Hazards Regulations 1984, and certain other instruments which amended them (regulation 24);
(r) contain a transitional provision (regulation 25).
