1.0 Introduction Construction activities are an important part of Dubai’s future. However all too

regular reports of deaths and injuries at construction sites highlight that these activities are very hazardous.

Zoning Authority is concerned about such accidents and determined to improve

safety standards across all projects under the jurisdiction of Zoning Authority. This Health, Safety and Environmental regulations contained within it are

intended to establish the future standard of operation for construction sites. These regulations have been developed from international practice.

The Health, Safety and Environment Regulations Manual have been framed to

regulate the working conditions of any workmen working under a contractor or sub-contractor involved in construction activities. Each employer shall provide a safe access, egress and safe place of work to all his employees engaged in construction work to protect them from accidents, occupational health hazards.

All the consultants, contractors working in Zoning Authority projects must adopt

its provisions and work to achieve an improved safety record for this important industry.

3.0 The Zoning Authority - Development Control’s Policy Statement on Enforcement of Regulations

3(a) The purpose and method of enforcement

The ultimate purpose of the Zoning Authority is to ensure that duty holders manage and control risks effectively, thus preventing harm.

1. The purpose of enforcement is to:

i. Ensure that duty holders (contractors) take action to deal immediately with serious risks.

ii. Promote and achieve sustained compliance with the regulations. iii. Ensure that duty holders who breach health and safety requirements,

and directors or managers, who fail in their responsibilities, may be held to account, which may include bringing alleged offenders before the courts.

2. The Zoning Authority has a range of tools at their disposal in seeking to

secure compliance with the regulations. Inspectors may offer duty holders information, and advice, both face to face and in writing. This may include warning a duty holder that in the opinion of the inspector, they are failing to comply with the regulations. Where appropriate, inspectors may also serve improvement and prohibition notices, withdraw approvals, issue formal cautions.

3. Giving information and advice, issuing improvement or prohibition notices

are the main means which inspectors use to achieve the broad aim of dealing with serious risks, securing compliance with health and safety regulations and preventing accidents. A prohibition notice stops work in order to prevent serious personal injury. Information on improvement and prohibition notices shall be made publicly available.

4. Every improvement notice contains a statement that in the opinion of an

inspector an offence has been committed. 5. Investigating the circumstances encountered during inspections or

following incidents or complaints is essential before taking any enforcement action.

Government of Dubai




Page 10 of 104

3(b) The principles of enforcement of regulations

Zoning Authority believes in strong, fair and effective enforcement of Health, Safety

and Environment regulations. It will follow the following principles.

3(b) (1) Proportionality:

Proportionality means relating enforcement action to the risks.

i. In practice, applying the principle of proportionality means that Zoning

Authority shall take particular account of how far the duty holder has fallen short of what the regulations requires and the extent of the risks to people arising from the breach.

ii. Where duty holders must control risks so far as is reasonably practicable,

Zoning Authority consider protective measures taken by duty holders, shall take account of the degree of risk on the one hand, and on the other the sacrifice, whether in money, time or trouble, involved in the measures necessary to avert the risk. Unless it can be shown that there is gross disproportion between these factors and that the risk is insignificant in relation to the cost, the duty holder must take measures and incur costs to reduce the risk.

iii. The Zoning Authority will expect relevant good practice to be followed.

Where relevant good practice in particular cases is not clearly established, health and safety regulations effectively requires duty holders to establish explicitly the significance of the risks to determine what action needs to be taken.

iv. Some irreducible risks may be so serious that they cannot be permitted

irrespective of the consequences.

3(b) (2) Consistency:

i. Consistency of approach does not mean uniformity. It means taking a

similar approach in similar circumstances to achieve similar ends.

Government of Dubai




Page 11 of 104

ii. Duty holders managing similar risks expect a consistent approach from Zoning Authority in the advice tendered the use of enforcement notices, approvals and in the response to incidents.

iii. Zoning Authority recognizes that in practice consistency is not a simple

matter. Zoning Authority – Development Control inspectors face with many variables including the degree of risk, the attitude and competence of management , any history of incidents or breaches involving the duty holders, previous enforcement action, and the seriousness of any breach, which includes any potential or actual harm arising from a breach of regulations. Decisions on enforcement action are discretionary by the enforcer.

iv. Zoning Authority shall have arrangements in place to promote consistency

in the exercise of discretion, including effective arrangements for liaison with other enforcing authorities.

3(b) (3) Transparency:

i. Transparency means helping duty holders to understand what is expected

of them and what they should expect from the Zoning Authority. It also means making clear to duty holders not only what they have to do but, where this is relevant, what they don’t. That means distinguishing between statutory requirements and advice or guidance about what is desirable but not compulsory.

ii. When inspectors offer duty holders information, or advice, face to face or in

writing, including any warning, inspectors will tell the duty holder what to do to comply with the regulations, and explain why. Inspectors will, if asked, write to confirm any advice.

iii. In the case of improvement notices the inspector will discuss the notice

and, if possible, resolve points of difference before serving it. The notice will say what needs to be done, why, and by when, and that in the inspector’s opinion a breach of the regulations has been committed.

iv. In the case of a prohibition notice the notice will explain why the prohibition

is necessary.

3(b) (4) Accident Investigation:

i. Zoning Authority – Development Control shall carry out a site investigation

in order to determine:

� Causes behind the accident/ incident

� Whether action has been taken or needs to be taken to prevent a recurrence and to secure compliance with the regulations

� Lessons to be learnt and to influence the regulations

� What response is appropriate to a breach of regulations?

� The severity and scale of potential or actual harm
