NEBOSH

The NEBOSH Health and Safety Management for Construction (UK) is aimed at site managers, contracts managers, construction health and safety advisors and workers with safety responsibilities. Study requires a minimum of 70 taught hours plus around 40 hours of private study with a NEBOSH Learning Partner. The single assessment, Unit CN1, is an open-book digital exam based on a realistic construction scenario: you download the paper at 11am UK time and have 48 hours to submit a series of applied tasks, followed by a roughly 10-minute closing interview that confirms the work is your own. The provisional pass standard is 45% and results arrive within about 50 working days. Content tracks CDM 2015 - client, principal designer and principal contractor duties, construction phase plans and the health and safety file - then the practical hazard elements: excavation and demolition, mobile plant, work at height, work equipment, electricity, fire, and occupational health from silica and asbestos to noise, vibration and stress. Passing supports the CSCS Academically Qualified Person card route. Question-style practice like this bank builds the fast rule recall that makes the open-book tasks manageable.

C.Involve more than one contractor working on site at the same time
D.Have a contract value exceeding 1 million pounds
Explanation: CDM 2015 regulation 6 sets the notification thresholds: more than 30 working days with more than 20 workers simultaneously at any point, or more than 500 person-days of construction work.

3A client is planning an office refurbishment that will involve a demolition contractor, an M&E contractor and a fit-out contractor. Under CDM 2015 the client must:
A.Notify the HSE because three contractors automatically makes the project notifiable
B.Appoint, in writing, a principal designer and a principal contractor because more than one contractor will be involved
C.Appoint only a principal contractor, since design work has already been completed
D.Allow the contractors to agree among themselves who will coordinate health and safety
Explanation: CDM 2015 regulation 5 requires the client to appoint a principal designer and a principal contractor in writing whenever it is foreseeable that more than one contractor will work on a project.

Explanation: Under CDM 2015 regulation 12, the principal contractor must draw up the construction phase plan (or arrange for it to be drawn up) before setting up the construction site; a plan is required for every project.
5What is the primary purpose of the health and safety file required under CDM 2015 for projects involving more than one contractor?
A.To record accidents and near misses that occurred during the construction phase
B.To provide information needed to ensure health and safety during future construction, maintenance, refurbishment or demolition of the structure
C.To demonstrate to the HSE that the principal contractor managed the construction phase competently
D.To list the training records and competence cards of all workers employed on the project
Explanation: The health and safety file, prepared by the principal designer and handed to the client at project completion, contains information (such as residual hazards, as-built drawings and locations of services) needed for safe future work on the structure.
6Which duty holder must provide pre-construction information, such as existing asbestos surveys and drawings showing buried services, to designers and contractors?
A.The client
B.The principal contractor

A.Domestic projects are exempt from CDM 2015 so no client duties apply
B.The homeowner must attend CDM awareness training before work can start
C.The client duties are normally carried out by the principal contractor (or contractor), unless the principal designer agrees in writing to take them on
D.The local authority building control officer automatically assumes the client duties
Explanation: Under CDM 2015 regulation 7, a domestic client's duties pass by default to the contractor (single contractor) or principal contractor (multiple contractors), though the principal designer can take them on by written agreement.

C.To prepare the construction phase plan covering the design elements
D.To carry out site inductions for workers affected by the design
Explanation: CDM 2015 regulation 9 requires designers to take account of the general principles of prevention: eliminate foreseeable health and safety risks through design choices, reduce risks that cannot be eliminated, and provide information about remaining risks.

C.A rest area and drying room, with sanitary facilities required only on notifiable projects
