11. Finalising the installation
After installation, fill in the pre-commissioning check list available from the Marioff project manager.
Commissioning of the system must be booked with the Marioff commissioning engineer well in advance (3-4 weeks) of the planned start date.
11.1 Unused materials
Make sure that the unused materials are not confused with spare parts delivered as part of the project.
It is the responsibility of the installer to keep a log of the materials and to send
information about them to the Marioff project manager. The project manager instructs the installer on what to do with the materials.
If the materials are returned, the installer will pack them without separate charge so that a courier arrange by Marioff can pick up the package. Details must be submitted, so the receiving Marioff storage knows which installation site the returned materials are from.
If Marioff does not want to take the materials back, they will become property of the installer. The installer can dispose of the materials as they want, with no additional cost to Marioff.
The installer may leave the site only after the site has been cleared of any garbage and waste materials and when the system and its installation has been made safe.
NOTICE! Any unused materials left over after the installation are Marioff property.
The installer must dispose of the waste materials, packaging materi-als and other garbage at their own cost. Extra materimateri-als must be recycled according to local regulations.

Each installer working on site must be properly trained for the performed tasks. Any installation work requiring authorization, such as electrical installation or hot work, may only be performed by persons with relevant permits and classifications.
Any persons handling high-pressure gas cylinders must receive Marioff approved training in compressed gas.
Local EHS regulations must be complied with. For example, a valid occupational safety card is required in some countries.
Risk assessment must be done together with Marioff before starting the work. Use the site risk assessment checklist for technicians. The purpose of the risk assessment is to assess any potential EHS risks related to the site and the installation work. Compliance with Marioff cardinal rules of safety is mandatory and these rules must be gone through in the risk assessment. If any of the cardinal rules cannot be followed, this implies a high safety risk on site. Contact Marioff immediately.
A.1 Site representative
The installer must appoint one of their employees on site to be responsible for ensuring that the installation team adheres to the relevant EHS requirements of the governing authorities applicable to the site, as well as any applicable rules and advice of the owner of the site. The appointed representative must have undergone training in both EHS regulations and also first aid training.
The appointed person must regularly inspect the work performed, equipment and processes used and take actions to rectify any shortcomings identified. All inspections and actions taken must be documented and forwarded to Marioff.

A.2 Cardinal rules
Compliance with Marioff cardinal rules of safety is mandatory.
1. Confined spaces
Confined spaces shall be identified and written procedures established and followed for entry.
A confined space is an enclosed area with the following characterics:
• Limited access and egress (exit)
• Large enough and so configured that a person can enter the space
• Not designed for continuous employee occupancy; examples include storage tank, process vessel, bin, boiler, ventilation and exhaust ducts, sewer, tunnel, vault, pipeline, space with an open top more than four feet deep such as pit or tub
Confined spaces pose limitations on working conditions because of the restricted space for equipment and people working on them.
Confined spaces must be identified in site-specific risk assessment and a procedure established for safe employee entry and rescue of employees from the confined space in case of emergency.
2. Fall protection
Employees shall use fall protection when exposed to a fall hazard (working at an elevated level of 2 meters (6 feet) or more).
For more information, see “Working at height” on page 63.
3. Electrical safety: ground fault circuit interrupters
Employees shall use 10 mA ground fault circuit interrupters (GFCIs) on all portable tools and portable electrical devices used in service/
maintenance, or installation activities at customer locations. Employees shall use Ground Fault Circuit Interrupters (GFCIs) on all portable tools and portable electrical devices used in all manufacturing/assembly/
overhaul & repair activities where construction activities are performed, or where there is the potential for exposure to damp/wet areas or the potential for damage to cords/plugs/receptacles.
For more information about electrical installation, see “Electrical installation” on page 53.

A.3 Working at height
The installer must use scaffolding, ladders, scissor lifts, mobile platforms and hydraulic lifts as necessary to install and access the equipment to ensure a safe installation. All ladders should be additionally supported where needed. For more information, see “Use of ladders” on page 65.
Any holes or openings in the ground surface must be guarded with balustrades or protective covers used to prevent employees from falling.
All staff using and/ or operating any access equipment must be given appropriate training in its usage and operation. When working at height, the area beneath the working area must be sectioned off to the public and designated a protective helmet area. Adequate care must be taken so that tools, equipment or other materials are not dropped when working at height.
All access equipment must be inspected and approved.
of lockout / tagout procedures when working on any electrical,
mechanical, hydraulic, pneumatic, compressed gas, chemical or thermal processes.
*Zero energy state is defined as the elimination and/or control of hazardous energy such that it no longer represents a hazard to employees.
5. Machine guarding
Employees shall not tamper with or disable machine /equipment guarding while operating under normal conditions.
All tools and machines must comply with EU machinery directive 98/37/EC or equivalent regulation depending of the location of the site.
64 P32010 C Marioff Corporation Oy Risk control measures for working at height are presented below.
Step 1. Bring the job to ground level.
If you can’t, take Step 2.
Step 2. Install a barrier or a balustrade.
If you can’t, take Step 3.
Step 3. Use a platform such as a scaffold or an elevated work platform.
If you can’t, take Step 4.
Step 4. Use a fall restrain system such as a harness and a fixed length lanyard that prevents you from reaching the edge.
If you can’t, take Step 5.

A.3.1 Use of ladders
Alternatives to reduce/eliminate the use of ladders shall be identified and implemented.
Where the use of other work equipment is not feasible because of the low risk and the short duration of the job or unalterable features of the work site, the use of ladder shall meet ladder use requirements outlined below. If local regulations deviate from the requirements below, local regulations must be adhered to. Any ladder used must comply with EN 131-1, 131-2 or equivalent.
If a ladder is used as a work surface, precautions shall be taken to reduce the potential for falling. Any employee working on a ladder at a height greater than 6 meters shall use appropriate fall protection.
Climbing a ladder must be done maintaining three-point contact (for example two feet-one hand, two hands-feet-one foot). Light tools are carried in a shoulder bag or holster
attached to a belt so that both hands are free for climbing. Heavy or bulky loads may not be carried up or down ladders - a pulley or other lifting device shall be used.
Any fixed ladder installed at a height of 6 meters or greater must be provided with one of the following forms of fall protection:
• Ladder safety cage
• Personal fall restraint system
Portable ladders must be labelled with appropriate manufacturer labels such as load capacities, rating, warnings and inspection criteria. Ladders may not be loaded beyond the rated load capacity.
All employees using ladders must be trained in ladder care, use and inspection. Ladders may not be used for purposes other than the original intention. Ladders made of
conductive material (for example metal or wood) may not be used for any job where exposed live electrical parts may be present.
