OTHER GENERAL ENVIRONMENTALREQUIREMENTS a) Monitorsfor hydrogensulfide must be installed wherever this gas may accumulate. The monitors should be set to activate warning signals whenever detectedconcentration levels of H.S exceed 7 mg/m3 (S ppm). b) An assessmemtof oil spill risks must be conducted,and an oil spill contingency plan must be developedand implemented. ENVIRONMENTAL GUIDELINES SPECIFIC TO OIL PIPELINES a) Positive pipe corrosion control measures b) Program of periodic inspectionand maintenance c) Pressuresensors connected to alarms and automaticpump shutdown systems. d) Mcteringsystemn should provide continuousinput/output comparison for leak detection. e) Adequateengineering design providing adequateprotection from likely extenal physical forces f) Accurate and complete records of all inspections,leak incidents,unusual events, and safety measures taken g) Minimizationof disturbanceto natural vegetation,soils, hydrologicalregimes, and topography h) Positivemeasures to control populationinflux to remote areas due to increased access created by the pipeline right-of-way,and to prevent associatedsecondauy impacts (e.g., encroachment on taditional indigenouspopulation lands or prserves; imcoauolled exploitationof natural resources) WORKPLACE AIR QUALITY a) Periodic monitoring of workplace air quality should be conductedfor air contaminants relevant to employee tasks and the plant's operations. b) Ventilation,air contaminantcontrol equipment,protective rcspiratoryequipment and air quality monitoring equipmentshould be well maintained. c) Protectiverespiratory equipmentmust be used by employeeswhen the exposure levels for welding fumes, solventsand other materials present in the workplaceexceed local or internationally acceptedstandards, or the following threshold limit values (TLVs): CarbonMonoxide 29 mg/m' Hydrogen Sulfide 14 mg/rn NitrogenDioxide S mg/rn' Sulfur Dioxide S mg/n?' e) Monitorsshould be insalled which activate an audible alarm when toxic gas concentrationsexceed 1/2 the above threshold limit values. WORKPLACE NOISE a) Feasibleadministrative and engineeringcontols, including sound-insulatedequipment and control rooms should be employedto reduce the averagenoise level in norrnal work preas. b) Plant equipment should be well maintainedto minimiz noise levels. c) Personnel must use bearing protectionwhen exposedto noise levels above 85 dBA. WORK IN CONFINED SPACES a) Prior to entry and occupancy,all confined spaces (e.g, tanks, sumps, vessels, sewers, excavations)must be tested for the presence of toxic, flammableand explosivegases or vapors, and for the lack of oxygen. b) Adequateventilation must be provided before entry and during occupancyof these spaces. c) Personnelmust use air-suppliedrespirators when working in confined spaces which may become contaminatedor deficient in oxygen during the period of occupancy. d) Observers/assistantsmust be stationed outside of confined spaces to provide emergency assistance,if necessary, to personnel working inside these areas. Onshorc Oil and Os DevelopmenV2 HAZARDOUSMATERIAL HANDLINGAND STORAGE a) All hazardous (reactive,flammable, radioactive, corrosive and toxic) materials must be stored in clearly labeledcontainers or vessels. b) Storage and handling of hazardousmaterials must be in accordancewith local regulations,and appropriate to their hazard characteristics. c) Fir: preventionsystems and secondary containmentshould be provided for storage facilities,where necessaryor required by regulation,to prevent fires or the rlease of hazardousmaterials to the environment. EALTH- GENERAL a) Sanitay facilities should be well equippedwith supplies(e.g., protctive creams) and employeessbould be encouragedto wash fequently, particularlythose exposedto dust, chemicals or pathogens. b) Ventilationsystems should be provided to control work area temperaures and humidity. c) Personnelrequired to work in areas of high tempweam and/or high humidity should be allowed to take fequent breaks away from these area. d) Pre-employmentand periodicmedical examinationsshould be conductedfor all personnel, and specific surveillanceprograms instituted for personnel potentiallyexposed to toxic or radioactivesubstances. SAFETY - GENERAL a) Shieldguards or guard railings should be installed at all belts, pulleys, gears and other movingpars. b) Elevatedplatforms and walkways, and stairways and ramps should be equippedwith handrails,toeboards and non-slip surfaces. c) Eleerical equipmentshould be grounded,well insulatedand conformwith applicablecodes. d) Personnelshould use special footwear,masks and clothingfor work in ares with high dust levels or contaminatedwith hazardousmaterials. e) For work near molten or high temperaturematerials, employees should be providedwith non-slip footwear, gloves, safesyglasses, helmets, face protection,leggings and other necessaryprotective equipment. 1) Eye protectionshould be wom by personnel when in a where there is a risk of flying chips or sparks, or where intense light is generated. g) Personnelshould wear protective clothingand goggleswhen in areaswhere corrosivematerials are stored or processed. b) Energency eyewash and showers should be installed in areas containingcorrosive materials. i) A safety program should be establishedfor consuaction and maintenancework. j) A fire prevention and fire safety program should be implemented nd include regular drills. TRAINING a) Employeesshould be fained on the hazads, precautionsand proceduresfor the safe storage,handling and use of all potentiallyharmful materials relcvnt to'cach employee's task and work area b) Training should incorporateinformation from the MaterialSafety Data Sheets (MSDSs) for potentially harmful materials. e) Personnelshould be tained in environmental,health and safety matters including accident prevention,safe lifting practices, the use of MSDSs, safe chemical handlingprctices, and proper control and maintenanceof equipmentand facilities. d) Training also should include emergencyresponse, includingthe location and proper use of emergency equipment,use of personal protectiveequipment, procedures for raising the alarm and notifying emergency response teams, and proper response actionsfor each foreseeableemergency situation. RECORDKEEPING AND REPORTING a) Tbe sponsor should maintainrecords of significantenviroanmental matters, including monitoring data, accidents and occupationalillnesses, and spills, fires and other emergencies. OinshorcOil and Gas Developmcnt3 b) This information should be reviewed nd evaluatedto improve the effectivenessof the environmcntal, health and safety progam. c) An annual summary of the aboveinformation should be providedto IFC.
