[edit] Introduction
The Construction (Design and Management) Regulations (CDM Regulations) are intended to ensure that health and safety issues are properly considered during a project’s development so that the risk of harm to those who have to build, use and maintain structures is reduced.
The regulations apply from concept design onward and impose duties on:
- The client.
- Designers.
- The CDM co-ordinator.
- The principal contractor.
- Contractors.
- Workers (including the self-employed).
The CDM Regulations describe a construction site as …any place where construction work is being carried out or to which the workers have access, but does not include a workplace within it which is set aside for purposes other than construction work.
It is not entirely clear from the regulations that there are specific duties imposed on workers, other than those imposed on ‘every person’ or ‘every duty holder’ however, they do impose duties on employers, contractors and principal contractors in relation to workers that by implication require worker engagement.
(The requirements below are only those that relate to workers, for other requirements, refer to specific articles about those duty holders)
[edit] Every person
- Every person concerned in a project who is working under the control of another person shall report to that person anything which he is aware is likely to endanger the health or safety of himself or others.
- Every person at work on a construction site shall, so far as is reasonably practicable, be instructed in the correct use of any fire-fighting equipment which it may be necessary for him to use.
[edit] Every duty holder
- Shall not accept an appointment or engagement unless he is competent.
- Shall co-operate and co-ordinate work to ensure the health and safety of construction workers and others who may be affected by the work.
- Shall apply the general principles of prevention.
- Shall not arrange for or instruct a worker unless the worker is competent, or under the supervision of a competent person.
[edit] Contractor
Shall provide suitable information and training, including:
- Site induction (where not provided by the principal contractor).
- Information about risks to their health and safety.
- Measures identified in risk assessments.
- Site rules.
- Procedures to be followed in the event of serious and imminent danger, and the identity of persons nominated to implement those procedures.
They should also provide their own employees with health and safety training.
[edit] Principal contractor
- Shall facilitate co-operation and co-ordination between all parties on site.
- Provide welfare facilities.
- Draw up rules which are appropriate to the construction site.
- Consult with workers or their representatives before making health and safety decisions.
- Ensure that notifiable details are displayed where they can be read by workers.
- Provide a suitable site induction.
- Provide information and training for the particular work to be carried out.
- Ensure that workers or their representatives can inspect and take copies of information which relates to the planning and management of the project.
[edit] Other measures
