Stress is the adverse reaction people have to excessive pressures or other types of demands placed on them. Work - related stress is a major cause of occupational ill - health which can cause severe physical and psychological conditions. Abyatona Development Contracting Company will assess the risks from stress associated with activities, in consideration of the following factors: • Demands – issues such as workload, work patterns and the work environment. • Control – how much say people have in the way they work. • Support – includes encouragement, sponsorship, and resources provided by the organization, line management and colleagues. • Relationships – includes promoting positive working to avoid conflict and dealing with unacceptable behavior. • Role – do people understand their role within the organization and does the organization ensure roles are not conflicting. • Change – how is organizational change (small and large) managed and communicated. Abyatona Development Contracting Company must ensure control measures are implemented to manage stress and to promote positive mental health and well - being, including consideration of the following: • Communication and open conversations to raise awareness of stress and reduce any perceived stigma. • Develop actions plans for people suffering from stress. • Provide mechanisms for raising concerns and grievances in a confidential manner. 13.2 Noise Abyatona Development Contracting Company must have arrangements in place for those exposed to noise during with their works. Collective protection must be chosen ahead of personal protection wherever practical. Areas and activities producing noise levels above 80 dB (A) must have signage posted and hearing protection must be available. Above 85 dB (A) hearing protection is mandatory and mandatory hearing protection signage must be displayed and an exclusion zone established. It is required to take specific action at certain exposure values. These relate to the levels of exposure to noise of employees averaged over a working day or week: • Abyatona Development Contracting Company must have the means and competence to Document Code : 03 - 150000 - 4800001134 - 0000011_02 Revision No: 02 Page 14 of 16 measure noise levels. • The lower exposure action value is a daily or weekly average noise exposure level of 80 dB, at which project management must provide information and training and make hearing protection available. • The upper exposure action value is set at a daily or weekly average noise exposure of 85 dB, above which project management is required to take reasonablyMpracticable measures to reduce noise exposure, such as engineering controls or Document Code : 03 - 150000 - 4800001134 - 0000011_02 Revision No: 02 Page 15 of 16 other technical measures. The use of hearing protection is also mandatory if the noise cannot be controlled by these measures, or while these measures are being planned or carried out. • Finally, there is an exposure limit value of 87 dB, above which no worker can be exposed (taking hearing protection into account). The accepted standard for recommended permissible exposure time for continuous time weighted average noise is for every 3 dBs over 80 dB, the permissible exposure time before possible damage can occur is cut in half (see below Table) 14 Mobile Equipment & Vehicle Operations (Friday/ Night &Extended hours) • All mobile equipment and vehicles operating in the hours of darkness shall have functioning headlamps and taillights and be equipped with orange flashing roof lights; • All roads, junctions and pedestrian crossings shall be illuminated and road signs shall be legible. • All mobile equipment and vehicle must comply with NEOM - HSAS under clause 17.0 VVS & PWAS , valid QR and 22.2 general requirements. • All mobile equipment and vehicle operator must fill the daily equipment inspection checklist prior to start of work.

Breakdown maintenance is maintenance performed on a piece of equipment that has broken down, faulted, or otherwise cannot be operated. The goal of breakdown - maintenance is to fix something that has malfunctioned. To the contrary, preventive maintenance is performed in order to keep something running. Sometimes it is performed because of an unplanned event. For example, if a critical piece of machinery breaks, the maintenance is performed because of the imminent need for that machine to operate again. However, breakdown - maintenance can be planned for in advance, which is what we might call “good” breakdown - maintenance. Breakdown Maintenance Wo rkflow 2 types of breakdown maintenance There are two types: Planned maintenance Planned maintenance means that the organization is prepared for a breakdown and even expects it to happen. The equipment runs until it breaks, which initiates a run to failure (RTF) trigger. While RTF triggers can be unpla nned, breakdown - maintenance plans use RTF as a way of lowering the cost of maintenance. This kind of plan needs to be rigorously documented and controlled. Employees should be clear on exactly which parts will break down and which parts will be maintained normally via preventive maintenance. Without these checks, a breakdown maintenance plan can be exploited or run awry. Unplanned breakdown maintenance Unplanned breakdown maintenance, on the other hand, occurs when a piece of equipment fails or breaks unexp ectedly — also called an unplanned downtime event. While some facilities may not utilize a planned maintenance plan, nearly every facility needs resources in place for unplanned maintenance. After all, every piece of equipment will break or fault at some point in its life. 5 examples of breakdown maintenance It is unique in its applications because it cannot be used with certain industries or products, especially ones that involve health and safety. This means that it is most frequently used when parts are inexpensive or nonessential. Here are some examples in which breakdown maintenance is applicable: • Equipment can’t be repaired at all (inaccessible, designed to not be repaired) • Asset consists of inexpensive or easy - to - replace parts • Non - critical pieces of equipment (like hand tools) • Objects/equipment that are disposable or meant to be replaced at the end of their lifespan • Short - life assets (batteries, high flow pumps) As you can see from these examples, it becomes viable when there’s no inherent safety risk to letting a part or piece of equipment break. As an example, consider a facility’s light bulbs. If a light bulb is not linked to a safety feature, it doesn’t make financial sense to replace it before it has burned out. However, it is absolutely not viable when people’s lives can be endangered by a part or product Document Code : 03 - 150000 - 4800001134 - 0000011_02 Revision No: 02 Page 17 of 16 breaking. For example, the aviation industry cannot rely on parts breaking down to fix them because doing so could threaten the personal wellbeing and this is also true for tire manufacturers who are responsible for road safety. When it comes to people’s lives, preventive and predictive maintenance are the right choice. 14.2 Lockout/tagout, or LOTO , are procedures used to ensure equipment is completely inoperable while maintenance and repair are completed. LOTO procedures are used to keep maintenance personnel safe from the unexpected start - up or release of hazardous energy. Effective lockout/tagout practices involve several critical steps that must be f ollowed to ensure the safety of all personnel involved. First, it is essential to identify all energy sources associated with the equipment, which may include electrical, mechanical, hydraulic, or pneumatic energy. Once identified, each energy source must be properly isolated and locked out. This involves placing a lock on the energy control mechanism, ensuring that the equipment cannot be inadvertently re - energized. In addition to physical locks, tags must be affixed to the equipment, clearly indicating th at maintenance work is being conducted and that the machinery must not be operated.
