HSE-BMS-003 Environmental Management.ppt
- 2. 2 What is meant by Environment? It is the surrounding in which we live; land, water, atmosphere, animals, trees etc, which can be affected by our activities All our activities produce waste in solid, liquid & gaseous form, which if discharged to the environment in excess quantities beyond its assimilation capacity can lead to pollution Introduction
- 3. 3 Environmental Policy Daewoo Engineering & Construction Co., Ltd. recognizes that the Earth environment is essential and will comply with the following environmental policy for planning and conducting the construction business for human survival not only for present but also for future generation. Environmental Management Point Minimize construction waste, effluent and promote recycling Prevent environmental pollution Provide adequate information, training and supervision Measure, monitor and review environmental performance
- 4. 4 This is a state in which the environment is contaminated with toxic materials, discharged by our activities, which are harmful to the flora, fauna & living beings - Air Pollution - Water Pollution - Land Pollution - Noise Pollution What is Pollution?
- 5. 5 What is meant by spill? This refers to the sudden or accidental discharged of contaminant into the environment Spill Control Plans Three processes are in place for effective management of waste water to avoid land surface and ground water contamination. - Batching plant process water - Treatment of batching plant toxic waste water before discharge - The high pH value is neutralized with the use of Aluminum Sulfate Spill
- 6. 6 • Battery charging operation - Sulphuric acid is being neutralized with soda ash before disposal • Materials for Clean-up & Control - Saw dust - Dry sand - Rags - Oil boom - Absorbent Pad Use Of Absorbents/Neutralizers
- 7. 7 Once a spill is noticed: Shout spill! Spill!! Spill!! To attract others - Notify all concerned (Including HSE) - Identify source of spill or leaks - Stop source of spill - Contain spill - Clean-up - Disposal of contaminated materials Spill Response Guide
- 8. 8 Release To Water or Soil Contamination Oil Diesel - Call departmental manager on channel xxx. - Call safety on channel x - Call Company emergency unit on channel xx - Identify the source/shut down the source. - Contain the spread - Arrange for clean up - Follow disposal procedures - Make written report Response Flow Chart
- 9. 9 Left over materials from the office, site and camps that are not useful in its present state and needs to be disposed off What Is Waste?
- 10. 10 Wood Used engine oil Used batteries Used tyres Oily cotton rag Oil contaminated sand Metal scrap Gaskets, glass waste etc. Sewage Kitchen waste Clinical waste Paper Carton Plastic Common wastes that are generated in the project are; Types Of Wastes
- 11. 11 Involves all the necessary procedure, practices, storage methods etc. That are put in place for the effective control of waste Waste Management
- 12. 12 Waste Stream Waste Generation Waste Segregation Waste Storage Waste Transfer Waste Disposal Team Waste Disposal Waste Documentation Waste Management
- 13. 13 Sewage - Treated & discharged Kitchen waste - Incinerated Clinical waste - Incinerated Paper waste - Incinerated / Recycled Plastic waste - Recycled Wooden waste - Recycled Used engine oil - Disposal by approved Agency Waste Disposal
- 14. 14 Used batteries - Recycled Used tyres - Disposed Oily cotton rag - Incinerated Metal scrap - Recycled Gasket - Disposed Glass wastes - Recycled Waste Disposal
- 15. 15 Waste Management Tips Reduce production of waste Segregate waste Recycle waste Disposed off waste Conserve resources
- 16. 16 Waste Management Waste management aim is to gradually reduce waste with the aim of eliminating those that have the potential to cause harm to people and the environment. It is criminal offence to dispose hazardous waste to nature or cause harm to the environment.
- 17. 17 Environmental Control Dust Pollution during Construction Phase Adequately sprinkle the area with water especially the road under construction to suppress or minimize dust. Water sprinkling of construction areas shall be done twice a day, morning and afternoon on a regular basis. Body of Water Protect all forms of body of water around the site that will be affected during the construction period this includes river, sea, swamp or lakes. No waste water coming from the construction site will be discharged to this body of water without proper treatment or tested to be safe and will not harm any form of living things in the environment.
- 18. 18 Environmental Control Noise Control Administer a continuing, effective hearing conservation program, as described in the procedure, whenever employee noise exposures equal or exceed an 8-hour time- weighted average sound level of 85 decibels measured.
- 19. 19 Environmental Control Hazards of Exposure to noise – Exposure to noise can have the following consequences; – Causes annoyance and irritation – Affects concentration and efficiency – Causes fatigue and accident proneness – Prevents ear from registering other sounds, instructions and warnings – Short exposure to excess noise causes damage to the inner ear and permanent loss of hearing
- 20. 20 Environmental Control Limiting Exposure to noise can be reduced by: – Engineering and control methods (e.g. installation of silencer, sound controlled equipment enclosure, replacing equipment with a low noise producing equipment if possible) – Job rotation – Providing rest rooms or acoustic refuges – Re-arranging work locations – PPE (ear plug, ear muffs)
- 21. 21 Environmental Control Soil Erosion The excavated or embanked area, shoulder on side slopes or borrow pits are the area where soil erosion are likely to occur during heavy rain. To avoid soil erosion, all exposed surface shall be regressed or covered by stone pitching, lining concrete, spill way and compaction of the embankment area shall be carried out. Operating Procedures: The operating procedures for various operations such as Acid neutralization, Auto Effluent Grease pit operation, Batching plant effluent neutralization should be displayed at the corresponding locations. The operating personnel in the corresponding locations should be trained to operate the above procedures.
- 22. 22 Summary Minimizse construction waste, and then dispose it to the designated area Implement waste segregation ang recycling Minimize the source of pollution by establishing target of saving energy and resources Strive that there is no environmental accident and violation of environmental legislation and regulation Environmental policy shall be open to the public as well as internal Each employee should understand and comply with the policy, and shall actively participate in and make utmost efforts to the environmental management activity
