• Primary Wastes: Domestic and municipal wastes• Secondary Wastes: Non-hazardous industrial and commercial waste

s• Tertiary wastes: Hazardous waste (radioactive wastes, toxic wastes,

and medical wastes)

8.6 Waste Segregation Program

Segregation is the prerequisite for implementing an effective and efficient management of wastes produced during the project. It refers to the physical separation of waste material, according to the physical and chemical nature. Segregation is important from a safety point of view and it allows wastes of a similar type to be combined, thus simplifying storage/treatment/recycling/disposal arrangements.

Hazardous wastes shall be stored in closed secure containers/drums, will be clearly marked or labelled, and segregated from other wastes until disposal. Drums shall be colour coded as per PTT requirements.

Each category of waste will be stored in an enclosed area, located adjacent to each other where possible to provide centralized pick-up. SEC will be responsible for the provision of the facilities dependent upon the waste category.

SEC will ensure proper segregation and isolation for wastes that could react together in the event of a leak or other incident. These facilities will include lockable, fire proof cabinets or storage in shelving units separated by fireproof barriers or walls.

SEC will dedicate a space for waste and drum storage. The storage area must be easily accessible for spill containment and emergency response and not be susceptible to flooding. Waste storage areas must have an adequate containment system:

• The containment walls and floor will be lined with an impermeable material. Dependent on the size, frequency of use and cost, concrete containment areas are a viable alternative to impermeable liners.

• The floor of the containment area should be graded to an interceptor sump in a corner of the storage area. The containment area will be inspected monthly for damage to containers, spills and the accumulation of storm water, or following a leak or spill.

Drains in areas designated for waste storage must be suitably equipped with plugs or deflectors, to prevent contamination of the environment or public drainage systems.

SHE MANAGEMENT PLAN


For any waste storage area which could accumulate hazardous gases, vapours or dust due to the nature of the wastes stored, SEC will supply suitable ventilation or other controls to ensure exposure by employees is kept below required minimum standards.

Ventilation systems for chemical and hazardous material storage areas will be designed in accordance with required industrial health and safety standards, and provide the required air exchanges as specified in the regulations.

Storage areas for hazardous wastes will be designated as restricted areas and will be suitably equipped to control an incident involving a leak or spill.

After identifications of risks in the risk assessment, the necessary method statements will be developed. Method of statements for SEC comments should be submitted in advance of starting the activity.

The main aim throughout will be to follow the principles of Prevention-Protection-Information-monitoring-review.

• If possible, avoid the risk completely, by using alternative methods or materials.

• Combat risks at source, rather than by measures which leave the riskin place but attempt to prevent contact with the risk.

• Wherever possible, adapt work to the individual particularly in the choice of work equipment and methods of work. This will make work lessmonotonous and improve concentration, and reduce the temptation t

o improvise equipment and methods.• Take advantage of technological progress, which often offers opportu

nities for safer and more efficient working methods.• Incorporate the prevention measures into a coherent plan to reduce p

rogressively those risks which cannot be avoided and which take into

SHE MANAGEMENT PLAN


account working conditions, organizational factors, the working environment and social factors.

• Give priority to those measures which protect the whole workforce or activity and yield the greatest benefit, e.g. give collective protective measures, such as suitable working platforms with edge protection, priority over individual measures such as safety harnesses.

• Supervision and the workforce need to understand what they need todo, e.g. by training, instruction and communication of plans and risk

assessments.• Monitor the control measures on a regular basis to determine the effe

ctiveness of the Risk Assessment.• Review and Revision of the risk assessment to be carried out if there

are developments that suggest it may no longer be valid (or that it can be improved). In most cases, it is prudent to plan to review risk assessments at regular intervals - the time between reviews being dependant on the nature of the risks and the degree of change likely in thework activity. Such reviews should form part of the standard SHE Ma

nagement Practice.• Each method statement will contain as a minimum but not limited to t

he following:-- The work activities to be carried out at any other parties involved at a particular location.- Key risks/controls taken from risk assessment and methods to achieve control of these and project SHE objectives.- Requirements for permits to work.- Necessary equipment and certifications.- Necessary training requirements.- Emergency response arrangements.- Limitations on working hours.

42 SHE Incentive Program

42.1 General

SEC will divide 2 types of awards as incentive program into Safety MH achievement without Lost Work Day incident cases and Best Safety Award. SEC shall plan the safety MH achievement award according to the construction schedule and manpower mobilization.

Best Safety Awards concept will be issued to individuals or Subcontractorwho fully complied with SHE requirement and actively participates in SHEactivities by eliminating and mitigating hazards to prevent accidents. It may include safety observation activities, site control activities related to SHE, etc.

SHE MANAGEMENT PLAN


Site Manager shall determine the milestone (MH, area completions, dates, etc.) although it will be updated as the project progresses.

The purpose of the SHE incentive program is to influence all employees to participate in the project SHE activities and to believe that SHE is a value and not just a priority and to influence the behaviour of individuals and groups and develop a project culture that manifests:

• “The work and personal health, safety and well being are in equal importance that we have to take the time to do it safely. It is the responsibility of each individual on-site themselves and the people around them to ensure that everyone leaves the job in the same condition as they arrived.”

SEC intends to recognize as well contributors of Unsafe Act/Unsafe Condition and Behaviour Safety program.

SEC will also provide target Project Safe working without LTI celebration milestone.

Subcontractors are encourage to participate in the SEC’s SHE Incentive Program which is designed to promote greater awareness of SHE control.

Subcontractors will be required to submit their own SHE incentive program to SEC for review and approval. The program must meet the requirements outlined in the SEC SHE incentive program and must also clearly show how employees shall be rewarded. SEC will prepare incentive scheme proposal. SEC shall implement the Subcontractor’s SHE incentive program and create competition in certain categories.

The program to be established on verifiable SHE performance based on the SHE program compliance and initiatives supporting the No accident goal. SEC SHE incentive programs shall be maintained like below:

43 Site Security43.1 General

SEC will provide adequate number of security personnel and security measure to safeguard the site from any threat, damage or theft of properties. SEC security personnel shall be equipped with communication equipment and able to contact police and other emergency units as required.

SEC will develop a site specific site security plan to limit and control access to the site of authorized personnel and vehicles and to provide secure conditions for materials and equipment to prevent theft or damage.

Site will be totally enclosed with a perimeter security fence and controlled access gates for personnel, vehicles/equipment and materials under control.

Mobile telephones will not be allowed on the work site and prior notice must be obtained from SEC Security prior to any photographs or video recordings being made. Photography/video permission will be limited to recording work progress, accident/incident investigation or award ceremonies.

SHE MANAGEMENT PLAN


43.2 Control Measures

SEC will construct a temporary fence along the perimeter of the site and with no gaps except for the entrance/exit to the site.

The site will have gates for the entrance and exit for all site personnel and materials/equipment working and required on the specific project.

Entry and exit of all persons into the site district will be controlled throughthese entrances.

• Gate houses to be provided at these locations and manned by security guards 24 hours/day, 365 days/year (for duration of the project).

• SEC to provide temporary security fencing and security systems to each of its temporary facilities and accommodation camps.

• SEC to provide temporary access/egress security gates at each worksite construction entrance.

Vehicular traffic through personnel entrances will be tightly restricted. Deliveries of materials/equipment will be directed to the storage/warehouse areas.

Visitors will be required to be signed in by a responsible security representative and visitors entering construction area must have personal protective equipment.

Vendor engineers and other long-term visitors will receive induction safety training.

SEC storage and warehouse areas are to be considered as "RESTRICTED" areas. Collection or removal of materials from those areas by Subcontractor is subject to SEC approval of a material issue(withdrawal) requisition and the attendance of a SEC representative.

On site communication will generally be handled by use of two-way radios approved by SEC.

SEC security personnel shall cooperate fully with Local Security Authorities at all times.

43.3 Identification Control

SEC ID card will be used in identifying and controlling all persons SECoperating facilities.

SHE MANAGEMENT PLAN


Badges will be displayed conspicuously on the outer clothing visible at all times.

SEC will assure that before commencement of work at site by a personnel, Security Section will be provided (name, positions, Passport Numbers and 2 Passport Size Photographs) and copies of CPR/Work Cards for issuance of Identity /access passes.

43.4 Material Control

All bags, packages, supplies, materials and equipment brought in or out of the Site will be subject to inspection by the security guards.

43.5 Vehicle Control

Vehicles entering the main construction gates will have permit either temporary (issued by the security main gate guards) or the ones issued by SEC to be displayed in the windshields.

All motor vehicles entering or leaving the site or other parking areas will be subject to random search by the security guard on duty.

• Spark arrestors on vehicles/Plant entering operational areas• Spark arrestors to be approved by SEC.

Subcontractor will submit a list of equipment, vehicles supposed to work at SEC premises for authorization and approval in advance.

44 Pre-Commissioning/Commissioning

SEC’s Commissioning Manager will nominate the authorized engineers and other qualified personnel who can issue work permits during the project commissioning phase to be carried out by SEC.

A Pre-Commissioning HSE Review will be conducted by SEC to ensure all hazard analyses, HAZOP study issues, required actions, project specifications and any deficiencies identified during Engineering Design Reviews are completed and verified prior to the start of commissioning.

SEC will ensure the results of all hazard analyses have been incorporated into the project commissioning training program and commissioning phase emergency response plan.

SEC will ensure that the results of the hazard analyses have beencommunicated to all personnel who will be on-site during the pre-commissioning, commissioning and start-up phases. SEC will ensure that there is a process in place to manage hazardous waste during the commissioning and start-up phase.

SHE MANAGEMENT PLAN


SEC’s SHE Plan, which incorporates commissioning HSE specifications, will be submitted to SEC’s Commissioning Manager for review and modification, if required. SEC’s Commissioning Manager will advise of the potential hazards that may occur during the phases of pre-commissioning, commissioning and start-up and ensure that the appropriate SHE and emergency response procedures are developed and inserted into SEC’s SHE Plan. Prior to commissioning activities, and the introduction of hydrocarbon into a unit area or facility, that unit or facility must be segregated by fence or barrier, and will have prominent signs posted in Thai language and/or English.

Hot liquids or vapours will never be discharged directly to atmosphere.Mitigating measures must be taken to prevent and control emissionsensuring that all fluids are discharged to an acceptable area and in a safe manner. Vessels that may contain highly toxic gases such as hydrogen sulphide require extreme care in the venting, purging, cooling and / or opening of such vessels or equipment.

No drain covers or manholes (which usually are gas tight) shall be opened without ensuring the drain section has been flushed out and all possible drainage entry points have been isolated.

All safety valves to be used shall be tested to ensure that they lift and re-seat at the specified pressures. Testing will be carried out at an approved workshop and witnessed by PTT’s Authorized Representative. Safety valves on steam-raising equipment shall be “float tested” in-situ to comply with engineering requirements.

SEC will ensure adequate ventilation, or extraction methods to facilitate removal of gas vapours and particulates must be provided to protect personnel from toxic emissions. Appropriate respiratory equipment must be available for worker use in such incidences. During catalyst loading workers must wear suitable respiratory personnel protective equipment. Prior to opening a vessel containing a catalyst all flammable gases and hydrocarbons must be purged from the equipment. Completion of purging must be verified by a gas test before opening the vessel.

Equipment protection systems must be functionally tested prior to anymachine or equipment testing. Running tests of gas turbines and the testing of over-speed trips shall be carried out by the Suppliers Only.

During tests where noise could be excessive (steam blow down) a system must be installed to give audible warning to all workers in the vicinity of the test prior to the start of the activity so evacuation can take place.

SHE MANAGEMENT PLAN


44.1 Simultaneous Operations (SIMOP)

It is SEC’s policy to conduct simultaneous operations in a manner such that a potential failure in one operation does not interact with another operation to create an unsafe condition of greater impact than would have occurred in a ‘stand -alone’ operation. A plan for simultaneous operations will be developed well before such activities commence.

44.2 Emergency evacuation plan

Due to the complete change in possible emergency scenarios from construction operations to the plant becoming ‘live’, the emergency evacuation will be amended to include all possibilities.

A Speaker/Public Address system will be introduced for audible warnings/information on emergency situations and emergency response infrastructure established and rescue equipment available.

Rescue equipment to include but not limited to:-

• Breathing apparatus sets with regulators, face masks and cleaning Kits.

• Basket stretcher for ‘horizontal’ rescue from heights.• Fire proof suits.• 100 meter hemp ropes for emergency rescue.• Vertical access tripod for entry/emergency rescue into vertical vessel

s, manholes etc.• Gin wheel pulley ropes.• Fire mans axes.• Portable first aid kits.• Resuscitator with

44.3 SHE Induction Training for the pre-com/commissioning stage

The existing SHE induction training will be revised to take into account the additional SHE precautions to be taken when working in ‘live’ areas.

SEC-SA.S1-90-1504.03-0640-012


1. PURPOSE

This procedure has been developed to outline hazards associated with noise and the preventive measures to be taken to prevent personnel working on Wangnoi Compressor Station (WCS) Project suffer from noise and induced hearing loss.

SEC shall comply with Thai legal requirements on noise exposures at workplace and communities near WCS project. The follow noise and time limits shall apply at boundaries of WCS project and within workplace.

2. SCOPE

The scope of this procedure covers noise control measures during construction and commissioning activities to protect all personnel working on site and to minimize noise impact to communities near WCS project.

3. DEFINITION

3.1 Noise

An unwanted sound which at certain volume level may cause irreparable damage to hearing.

3.2 Frequency

The pitch measured in Hertz, calculated from the rate of pressure fluctuations of sound waves.

3.3 dB (A)

Decibel – unit to measure noise. The characteristic of sound which are filtered to replicate the noise heard by the human ear.

3.4 Attenuation

The reduction of noise achieved by hearing protection, each type of ear protector should have attenuation tables which illustrate the noise reduction at different frequencies. e.g. 30dB (A) at 5,000 Hz.

3.5 First Action Level of 85 dB (A)

This requires employers to provide employees with information about the risks to hearing and provide hearing protection on request.

This level requires control of noise exposure by:

1) Limiting the noise at source, as the first step 2) Requiring hearing protection to be worn 3) Limiting the time people are exposed to noise


SEC-SA.S1-90-1504.03-0640-012


4. RESPONSIBILITY

4.1 Construction Manager

To advise on the procurement of hearing protection.

To carry out noise assessment where and when necessary, and produce noise contour maps with octave band frequencies analyzed.

To ensure that the appropriate signs are displayed for areas where high levels of noise exist.

To prepare toolbox talks and other training material for briefing the workforce.

To develop and administer a continuing, effective hearing conservation program.

4.2 SHE Manager

Functional as an adjudicator on any issues from the implementation of this procedure.

Audited CONTRACTOR and Subcontractors to ensure the requirements of this procedure are implemented and will be provided feedback on performance to Contractor Management.

Assisted Subcontractor to plan and coordinate the work to effectively implement the Requirements of this procedure

Ensured the requirement HSE records are generated and available for review by Management and Authorities as appropriate.

4.3 Safety Officer

Supervision when planning the work shall take into account the anticipated noise levels that persons under their control may be exposed to.

To consult with the HSE department and arrange for a noise analysis, where any concerns exists.

To provide adequate and suitable hearing protection for the work being performed recognizing the attenuation factors of different types of hearing protection.

Arrange training to persons exposed in the use of hearing/protection.

4.4 Environmental Officer

Noise monitoring and measurement record

EIA prevention and mitigation measures as following in Thai legal

4.5 Noise Limits

4.5.1 Construction Area

Working after SHE plan and project EIA prevention and mitigation measures as following:


SEC-SA.S1-90-1504.03-0640-012


- 85 dB(A) for 8 working hours in day time

4.5.2 Residential Area

The noise levels at residential area around WCS project will be complying with the noise standard as the Notification of Environmental Board No.15 B.E.2540(1997) and Notification of Environmental Board No.29 B.E.2550 (2007) and project EIA prevention

and mitigation measures as following:

- Equivalent continuous sound level (Leq) 24 hours should not exceed 70 dB(A) For steady noise

- Maximum sound level (Lomax) should not exceed 115 dB (A) from fluctuation noise

- Annoyance level should not over 10 dB(A) from background noise (L90)

5. INSTRUCTION

5.1 General

Sound is measured in decibel (dB). The decibel scale is logarithmic and it doubles with every increase of 3dB, i.e. 78dB is twice as loud as 75dB and 81dB is 4 times as loud.

The effect of noise on the hearing is cumulative. Noise exposure is normalized to an 8- hour working day over a 40-year working life.

Whenever possible reduce the noise at source. Loud noise can cause :

1) Permanent damage to hearing. 2) Hearing to become less sensitive. 3) Permanent ringing in the ears. 4) Breakdown of safe communication

If, with normal hearing, a person has difficulty in conducting a normal conversation at 1 meter then the noise level in the vicinity is approximately 90 dB; difficulty at 2 meters means the noise level is approximately 85 dB. Where possible, move away to a quieter location.

5.2 Occupational Noise Exposure Protection against the effects of noise exposure shall be provided when the sound levels exceed those shown in the table (Appendix 1 Permissible Noise Exposures) when measured on the A-scale of a standard sound level meter at slow response. Exposure to high levels of noise over the extended periods will damage hearing. Noise- induced hearing loss is IRREVERSIBLE.

When persons are subjected to sound levels exceeding those listed in the table, feasible administrative controls (job rotation-reduction of exposure hours, etc.) or engineering controls shall be utilized.


SEC-SA.S1-90-1504.03-0640-012


Should the introduction of administrative or engineering controls fail to reduce sound levels within the levels shown on the table (Appendix 1 Permissible Noise Exposures), personal protective equipment (hearing protection) must be provided and used to reduce sound levels within the levels of the table. Various styles of hearing protection (earmuffs–earplugs-canal caps etc) reduce different levels of noise and therefore, the manufactures attenuation table (supplied with the hearing protection) must be studied to calculate the effectiveness of the hearing protection. During extremely high noise levels earplugs and earmuffs may need to be worn.

When persons are in a hearing protection area the hearing protection must be worn at all times. Removing hearing protection for just 30 minutes in a 8 hour period reduce the overall protection afforded by 40%.

In all situations where the sound levels exceed the values shown on the table, a continuing, effective hearing conservation program shall be administered.

The phenomena of noise induced hearing loss has only, relatively speaking, been recently analyzed and understood. The causation factors of working in industries where high levels of noise are generated are now clearly understood, and the long term consequences created from working in such high risk environments placing greater levels of care on employing companies.

The physiological damage of working in environments where high levels of noise exists can be simply explained as the damage caused to the fine hairs in the Cochlea, part of the hearing mechanism sited in the inner ear. These hairs are joined to nerves transmitting the sensation of hearing to the brain; prolonged exposure to high levels of noise will result in auditory fatigue and eventual failure of function for that fine hair. This may result in temporary deafness called a ‘Temporary Threshold Shift’ or permanent deafness which includes the occupational illness of ‘Noise Induced Hearing loss.

The damage to the fine hairs in the cochlea usually results in a person suffering ‘Tinnitus’ (constant sounds in their ears such as buzzing, ringing or whistling), even when a person is in a quiet area or resting these sounds are always present. The provision of a hearing aid serves very little purpose, as the hearing aid will only amplify the sounds.

The first action level for noise on WCS Project is 85 dB (A) and over. This will require the provision of information to persons on the risks to hearing and the issue of hearing protection when requested.

The second action level for noise on WCS Project is 90 dB (A) and over. This will require the provision of signs, mandatory hearing protection, and analysis of the noise emissions, limiting the time people are exposed to noise and reducing the noise at source.

The maximum noise levels to which anyone may be exposed to are 115 dB (A) continuous and 140 dB (A) impulse or short duration. This includes personnel wearing hearing protection.

Instances where personnel are exposed to high levels of noise may require screening to assess If any impairment has occurred.

In areas where noise may interfere with communications, suitable alternative arrangements shall be in place for alerting the work parties in the event of an emergency.


SEC-SA.S1-90-1504.03-0640-012


5.3 Assessment

Assessments must be carried out in order to: 1) Identify all persons likely to be exposed at, or above the second action level.

2) Provide enough information to enable appropriate action to be taken.

The exposure of persons to noise must be reduced, as far as is reasonably practicable, without the use of hearing protection.

As with any item of personnel protective equipment, the use of it should be the last resort. Determined efforts should be made to ‘engineer out’ the noise.

5.4 Methods of Noise Reduction

The table (Appendix 2. Guidance on Sources of Noise in Construction Industry) provides guidance on sources of noise in the construction industry and possible remedies to reduce noise levels.

When construction activity generate noise level exceed THAI Legislation both Environmental noise and occupational noise. Temporary noise reduction wall shall be provided by SEC

5.5 Information instruction and Training

Where persons are likely to be exposed to noise levels of 85 dB (A) and above they must be provided with the following:

1) Information on the risk to hearing. 2) Provision of suitable hearing protection. 3) Instruction and training on the correct use and maintenance of the hearing protection. 4) Circumstances where ear protection needs to be worn. 5) Information supported by suitable warning signs in ear protection zones.

5.6 Noise Values associated with Construction Equipment

The table (Appendix 3 Examples of Noise Levels) features approximate noise levels associated with general construction equipment. A-weighted Equivalent Continuous Sound Level(Leq) 24 hours should not exceed 70 dB(A)

5.7 Environmental Noise

Good relations with persons living and working in the vicinity of the site operations are of particular importance.

Early establishment of relations and liaise on throughout the site operations will go a long way in identifying and resolving problems associated with noise impact on the local environment.

All available techniques should be used to minimize as far as possible, the level of noise to which site personnel and others in the area of site operations will be exposed.


SEC-SA.S1-90-1504.03-0640-012


Measures which could be taken include:

1) Restrictions on hours of work for high noise activities. 2) Control of noise at source for example :

Substitution of noisy equipment with quieter machinery. Enclosure of machinery on sites using plywood hoardings or earth bunds. Sitting of static plant i.e. crushers, batching plant etc. away from noise sensitive boundaries if possible. Regular and effective maintenance to plant and other equipment will result in quieter and more efficient running of plant and equipment. Such reduced plant noise will assist in the control of environmental noise.

5.8 Commissioning noise control

All available noise detector shall be prepared commissioning area after hazard analysis among sub-contractor which needs to be provided based on regulations. and exposure area due to operating equipment for commissioning shall be provided additional noise personal protective equipment in front of entrance area as well as cross check by in charge staff before entrance. and Commissioning area shall be checked by periodically noise conditions by certified detector with record. If noise record is acceptable within noise standard from client then it can be established free-area for noise protection after checked with in charge department.
