Hearing Conservation Program (HCP) in AMD SingaporeHearing Conservation Program (HCP) in AMD Singapore
• HCP implemented and maintained for all personnel exposed to
excessive noise so as to minimize the risk of hearing loss.
• HCP and its elements:
� Noise Hazard Identification – Risk Assessment and Noise Monitoring.
� Implementation of Noise Control Measures – control at source or along
transmission path or at receiver as per principles of noise control.
� Use of hearing protection (PPE) until engineering controls implemented.
� Periodic health surveillance (audiometry test) for early detection of
hearing loss.
� Training on “Hearing Conservation Program” for personnel exposed to
excessive noise.

Workplace Noise MonitoringWorkplace Noise Monitoring
Administrative Controls and PPEAdministrative Controls and PPE
• Selection, issuance, use and maintenance of hearing protectors.
• Posting of hearing protection warning signs at noisy workplaces.
• Communications of hazards / risks to all personnel exposed to noise.
• Maintenance of register for personnel working in noisy areas.
• Yearly audiometry test for all personnel working in noisy areas.
• Evaluation of audiometry test results by EHS Office and endorsed by
Management.
• Communication of test results to affected personnel.

HCP Implementation and AchievementsHCP Implementation and Achievements
• Noise reduction projects completed for following areas and reduced
noise levels through engineering control measures:
� Noise Reduction for Crushing Room reducing noise exposure level from
100.3 dB(A) to 77.5 dB(A).
� Noise Reduction for liquid nitrogen filling operation reducing noise
exposure level from 101.9 dB(A) to below 72.9 dB(A).
� Noise Reduction for temperature cycle chambers in Reliability Lab
reducing noise exposure level from 90.2 dB(A) to 79.9 dB(A).
• The organization received “Outstanding Achievement Award” for the
above noise reduction projects for two consecutive years (2006 &
2007).
Noise Reduction Project for Noise Reduction Project for Crushing RoomCrushing Room
Benefits
1. Improvement of employees health & safety and environment.
2. Elimination of workplace safety risk thereby improving employee work morale.
3. Cost avoidance of S$2,000 per year for administrative controls & PPE.
Cost
S$3,000 for implementation of engineering control measures to reduce noise (excluding internal labor).
Risk/ Exposure Level after control
Personnel working in crushing room are exposed to noise level of 77.5 dB(A) for 8 hours per day which is below permissible levels as stipulated under Factories (Noise) Regulations.
Risk/ Exposure Level before control
Personnel working in crushing room were exposed to a noise level of 100.3 dB(A) for 8 hours per day. Personnel involved in work were wearing hearing protectors and were sent for audiometry test on annual basis.
After Created a soundproof opening for crushing room such that crushing machines can be operated from opposite side of the wall, thus minimizing noise exposure to the operators. With the installation of the soundproof doors, the operator will pour the units into the crusher from the opposite side of the wall, close the door and start the machine.
Before
Source of Hazard: Crushing Machines inside crushing room.
Frequency / Duration of Exposure: 100.3 dB(A) for 8 hours per day.

Filling OperationFilling Operation
Benefits
1. Improvement of employees health & safety and environment.
2. Elimination of workplace safety risk thereby improving employee work morale.
3. Cost avoidance of S$1,000 per year for administrative controls & PPE.
Cost
S$2,500 for implementation of engineering control measures to reduce noise (excluding internal labor).
Risk/ Exposure Level after control
Personnel involved in filling liquid nitrogen (LN2) were exposed to noise level of 72.9 dB(A) for 8 hours per day which is below permissible levels as stipulated under Factories (Noise) Regulations.
Risk/ Exposure Level before control
Personnel filling liquid nitrogen (LN2) were exposed to a noise level of 101.9 dB(A) for 8 hours per day. Personnel involved in work were wearing hearing protectors and were sent for audiometry test on annual basis.
After
Added an additional new pipe fitting on the LN2 container during refilling and noise and vapors are made to travel through this piping and later diverted to the end of the building where a silencer is fixed there. In this manner, liquid nitrogen (LN2) refilling area was freed of noise & ventilation problem.
Before
Source of Hazard: Before refilling of LN2 container, air pressure needs to be released through “VENT” nozzle. Due to this, the end users experienced very sharp “hissing”sound.
Frequency / Duration of Exposure: 96.3 dB(A) for 8 hours per day.

2. Elimination of workplace safety risk thereby improving employee work morale.
3. Cost avoidance of S$4,000 per year for administrative controls & PPE.
Cost
S$7,800 for implementation of engineering control measures to reduce noise (excluding internal labor).
Risk/ Exposure Level after control
Personnel working in Reliability Lab are exposed to noise level of 79.9 dB(A) for 8 hours per day which is below permissible levels as stipulated under Factories (Noise) Regulations.
Risk/ Exposure Level before control
Personnel working in Reliability Lab were exposed to a noise level of 90.2 dB(A) for 8 hours per day. Personnel involved in work were wearing hearing protectors and were sent for audiometry test on annual basis.
After
All the outlet valve of heater boxes were covered with ventilated noise louver window and most of the exterior surface of temperature cycle chamber casing were lined by acoustic absorbent materials to cut down the noise generated from the heater boxes.
Before
Source of Hazard: Compressed air nozzle of heater box fitted in liquid nitrogen temperature cycle chambers.
Frequency / Duration of Exposure: 90.2 dB(A) for 8 hours per day.
