    Indoor Air Quality RIL Group Standard

    Introduction

    Reliance believes in providing the best possible health environment to its personnel

    working within its premises. This applies to the manufacturing facilities as well as theoffice premises. Indoor air quality plays a major role in keeping the personnel in goodhealth, motivated to work consistently during the working hours and is a majorcontributing factor for achieving maximum productivity irrespective of the seasons andnature of the work. As part of the global best practices, this standard has been formulatedto ensure the best indoor air quality to the personnel working at RIL.

    Intent and Purpose

    This standard has been developed by an inter-site workgroup with guidance ofexperts from DuPont Safety Resources. The requirements which have beenidentified here are equally applicable across all locations and group companies.This will also help in bringing about a consistency in the process used across all

    locations.

    The Standard will help to provide a new impetus towards achieving the best inclass safety standards. This revision-0 release of the standard is formulated basedon world class practices and with the help of DuPont Safety Resources.

    Comments and feedback would be appreciated to further enhance this process.All such comments and feedback may be addressed [email protected]. The comments and feedback would beconsolidated and shall be used during the review and revision of future releases

    1. Scope and field of application

    Revision 0Aug 2008 Page 6 of 26

    1.1. ScopeThis standard provides mandatory requirements and advisory guidance formanaging indoor air quality (IAQ) to prevent and correct conditions that mightlead to illness, discomfort, or poor productivity. More detailed guidance can befound in the references listed in Section 2.

    This standard applies to all areas with continuous human occupancy (e.g.,operating areas, offices, control rooms, lunchrooms, and meeting rooms). The

    extent of the IAQ program is determined by an initial IAQ assessment (refer toSection 5.1). The IAQ program is simpler and less formal for facilities that aresmall and have fewer risk factors and occupants. IAQ programs are more complexand formal for larger, more complex, high-occupancy facilities.

    Businesses/Locations should be aware that local regulations might imposeconditions not reflected in this standard. Additional information on regulationscomes from a number of sources, including Statutory/Regulatory Documents.

    While the intent of the Standards is to bring in homogeneity across all Businesses/ locations in the implementation of the standards, certain provisions are kept toallow some latitude to the implementing locations. However, those requirementsin this standard which are noted in italics are mandatory. Any question regarding

    5. Standards/guidelines5.1. Initial indoor air quality assessment

    Each site shall conduct an initial assessment of IAQ and heating, ventilation,and air conditioning (HVAC) systems for human-occupied facilities (e.g.,offices, control rooms, operating areas, lunchrooms, and meeting rooms) todetermine if conditions exist that could lead to IAQ concerns.

    Such conditions may include the following:

    IAQ-related complaints from occupants High-occupancy load A complex, central forced-air HVAC system that has not been recentlyinspected or cleaned

    Individual or window-type air conditioning units that have not beenrecently inspected or cleaned

    The presence of water or moisture sources in the HVAC system (e.g.,humidifiers, air washers/ scrubbers, and carryover from coils or leaks)

    A history of roof leaks or the presence of wet carpet, walls, and/or ceilingtiles in occupied indoor areas

    Relative humidity (RH) that is frequently above 60 percent in occupiedindoor areas

    Visible microbial growth on indoor areas (e.g., walls, carpet, or ceiling tiles)or in the HVAC system ductwork, heat exchangers, or other components

    Stale and objectionable Odor.Facilities identified as having the potential for IAQ concerns must be included in

    an IAQ program as described in this standard.

    5.2. Training and communicationEmployee training and communication shall be completed periodically and

    include the following responsibilities:

    All personnel shall observe their work areas and report any IAQ problems

    Revision 0Aug 2008 Page 10 of 26

    All personnel must report to a RIL Occupational Medicine Services (OHS)health-care professional any symptoms that might be workplace-related,

    cooperate in any incident investigation/medical evaluation, and follow site

    procedures.

    Responsible personnel (e.g., maintenance) should be trained on the following:

    System/facility inspection, cleaning, and maintenance procedures,including safety and health hazards and precautions and appropriate PPE.

    Systems and procedures to isolate, ventilate, or otherwise control emissionsfrom cleaning or maintenance activities

    Building occupants should be informed of the following:

    IAQ concerns that are identified and the facilitys response to them Activities or materials that may emit air contaminants Their responsibility to:

    o Report any discomfort or symptoms to line management and to aRIL OHS health-care professional

    o Report water leaks; building / facility, sanitation, andhousekeeping concerns; and perceived fresh air insufficiency

    o Keep air diffusers or return inlets unblockedo Store food properly and dispose of perishables (e.g., food scrapsand beverage containers) only in designated trash receptacles

    For occupants who are contract employees or non-company tenants, such

    communications should be coordinated through a contractor/tenant

    representative. Documentation of these communications should be maintained.

    Refer to RIL Administration of On-Site Contractor Safety Standard for additional

    guidance

    5.3. IAQ program coordinatorThe OH resource or team, maintenance, or another party designated byleadership must coordinate the IAQ program. The roles of maintenance, OHS,occupational health resources, leadership/the OH champion in the IAQ program,and occupants should be addressed.

    Revision 0Aug 2008 Page 11 of 26

    5.4. Maintenance/EngineeringThe facility maintenance/engineering organization plays a key role in the IAQprogram and shall integrate IAQ into other preventive maintenance, repair,

    service, and design responsibilities.

    Indoor Air Quality RIL Group Standard

    5.6. HVAC system operation and service5.6.1. Operation

    The system should be operating when areas are occupied, and areas

    with natural ventilation should be open to operable wall or roof

    openings to the outdoors (e.g., windows)

    5.6.2. Outdoor Air qualityAt least the minimum amount of outdoor air should be available for

    the specific use as cited in ANSI/ASHRAE Standard 622001 and

    other applicable codes/standards. As a general rule, if the indoor

    carbon dioxide level exceeds the outdoor concentration by more than

    about 700 ppm, this may indicate inadequate ventilation.

    Outdoor air intakes should not be located close to sources of air

    contaminants (e.g., lab hood exhausts, vent pipes, vehicle exhausts,

    cooling towers, or stagnant water). The distance from the air intake to

    sources of contamination, prevailing wind speed and direction, and

    any objects that might influence airflow should be considered in this

    evaluation.

    5.6.3.

    Relative humidity

    RH shall be maintained below 60 percent where the facility HVAC

    system has the ability to dehumidify. This helps prevent microbial

    (e.g., mold and mildew) growth in ducts and building materials (e.g.,

    carpeting, furnishings, or wallboard). Facilities that cannot maintain

    the humidity below 60 percent should be inspected and cleaned more

    frequently than those with humidity control.

    Facilities should consider providing continuous exhaust from damp

    areas (e.g., rest rooms and showers) to remove humidity from the

    building.

    Revision 0Aug 2008 Page 13 of 26

    5.6.4. ComfortThe temperature in occupied areas should be maintained within a

    comfortable range. Airflow should be controlled to prevent drafts, air

    imbalance, odors, and stuffiness to promote the comfort of occupants

    and enhance productivity. ASHRAE Standard 55-1992 and other

    applicable codes/ standards should be followed to help ensure thermal

    comfort.

    15/25

    Indoor Air Quality RIL Group Standard

    5.6.5. Inspection and Cleaning - microbial growthInternal HVAC system surfaces and components (e.g., ducts,

    dehumidifiers, heat exchangers, heating and cooling coils, drip pans,

    and fans) shall be periodically inspected for microbial growth andcleaned. Inspections should be done annually, unless experience

    indicates that a different frequency is appropriate. Cleaning heat

    exchanger coils and fans keeps the units operating efficiently, which

    both saves energy and protects occupants.

    Unless the recommended PPE (e.g., respirators, gloves, and eyewear)

    is specified in standard operating procedures (SOPs), personnel

    cleaning or inspecting HVAC equipment must consult their

    occupational health resource.

    5.6.6. Equipment Service and filtrationEquipment inspections and service should be conducted just prior to

    each cooling or heating season according to the manufacturers

    recommendations to help ensure effective and efficient operation.

    Filters should be changed and service performed on water-based air

    treatment units monthly, or as appropriate, based on inspection.

    High-efficiency pleated filters are recommended.

    Revision 0Aug 2008 Page 14 of 26

    5.7. Control of Legionella and other microbial contamination inwater sources

    Under ideal conditions, water systems may become reservoirs for microbialcontaminants (e.g., bacteria and fungi). Inhalation of water droplets or an aerosolof water contaminated with microorganisms may result in illness (e.g.,legionellosis, hypersensitivity pneumonitis, or humidifier fever).

    Legionella bacteria are commonly present in natural and manmade aquaticenvironments; however, under certain conditions, amplification may occur.Conditions that are favorable for the amplification of Legionella growth include

    water temperatures of between 25C and 42C, stagnation, scale and sediment,biofilms, and the presence of amoebae.

    When considering areas with continuous human occupancy (see Section 1.1), thepotential for human exposure to microbial contaminants from water sources hasthe highest potential in cooling towers, water in internal HVAC systems (seeSection 5.6.5), showers, and industrial process/chilled water systems.

    A water treatment program should be provided for each system. This is specific toeach system and may include biocide or anticorrosion or antiscale products. Thesite water treatment vendor or a water treatment consultant should be contactedfor help in setting up and maintaining a water treatment program.

  • 7/28/2019 1217595181797 RIL Indoor Air Quality Standard Rev-0 Aug 2008

    16/25

    Indoor Air Quality RIL Group Standard

    Each location shall perform a risk assessment to identify and assess the risk of

    Legionellosis. A competent person who has an acceptable understanding of the

    potential areas of concern (i.e., Legionella) and the appropriate controls should

    conduct this risk assessment. The assessment should be reviewed annually and

    documented.

    Drinking water should also be considered, but it is a less likely source, as long as

    the local drinking water supplier maintains chlorination levels. Bottled drinking

    water is more prone to microbial contamination, the source most often being

    inadequately maintained water dispensers.

    5.7.1. Cooling TowersCooling towers provide an ideal environment for microbial growth,

    including bacteria, fungi, algae, and protozoa. These microorganisms,including Legionella, can then be released as part of water mist aerosol

    emanating from the tower.

    During the design phase for new or refitted cooling towers, the

    following should be considered so that the cooling tower poses a

    minimal health risk to building occupants and the public:

    The tower should be located as far as possible from HVAC fresh airintakes, open windows, occupied areas, pedestrian thoroughfares,

    areas of public access, and kitchen exhaust. Wind direction andwind distribution over neighboring buildings should be taken into

    account.

    There should be no deadlegs (i.e., low spots in the system thatcannot be drained, allowing water to accumulate and stagnate).

    Construction materials that do not support microbial growth (e.g.,avoid wood) and can be readily disinfected should be specified.

    Effective, high-efficiency drift eliminators should be fitted andmaintained.

    Cooling towers shall be maintained by

    Periodically inspecting for physical defects and the presence ofsludge, slime, algae, scale, rust, or foreign matter.

    Revision 0Aug 2008 Page 15 of 26

    Note: The frequency of inspection should be based on the risk

    assessment required by Section 5.7. It is recommended that these

    inspections be conducted at least monthly.

    Periodically or continuously treating water, as appropriate,based on the risk assessment, to minimize microbial growth,

    scale, corrosion, and sediment/deposition of solids on heat

    transfer surfaces.

    Conducting periodic water analysis, both chemical analysis andtesting for total bacterial counts (heterotrophic or standard plate

    count).

    Note: A water treatment vendor, trained RIL personnel, or athird-party vendor should conducton-site monitoring.

    Reviewing the water treatment procedures, auditing forcompliance, and making appropriate adjustments if testing for

    total bacterial counts indicates levels >100,000 colony-forming

    units (CFU)/mL.

    Note: If standard plate count testing indicates levels >100,000

    CFU/ml or if ATP-based monitoring indicates levels >1,000 relative

    light units (RLU), the water treatment procedures should be reviewed,

    audited for compliance, and any needed adjustments made. It may be

    appropriate to set specific levels for individual cooling towers.

    Periodically cleaning and disinfecting the tower in accordancewith manufacturers guidelines.

    Note: This is typically done once every six months.

    5.7.2. Potable water systemsPotable water systems include piping, hot water heaters, storage tanks,

    faucets, nozzles, and other distribution outlets. The following

    measures should be followed to minimize the potential for microbial

    growth, including Legionella, in these water systems:

    Design temperatures in both hot and cold water systems should bemaintained by providing efficient heating for hot water systems

    and adequate insulation for all pipes and fittings.

    Water stagnation should be avoided by keeping pipe lengths asshort as possible, minimizing the size of water tanks as much as

    possible, and eliminating dead-legs wherever possible.

    Revision 0Aug 2008 Page 16 of 26

    Hot or cold water systems that incorporate an elevated holdingtank (e.g., water tower) should be inspected annually and cleaned

    as appropriate.

    Systems should be protected (e.g., by providing lids to storagetanks) against external contamination.

    Showerheads should be removed annually to remove sediment andscale and cleaned in a dilute chlorine bleach solution.

    Potable water systems that were opened up for repair or otherconstruction or systems that were subjected to water pressure

    changes associated with construction should be thoroughly flushed

    as a minimum precaution before returning them to service.

    5.7.3. Other water systemsThe following measures should be followed to minimize the potential

    for microbial growth, including Legionella, in these water systems:

    Direct evaporative air coolers, misters (atomizers), airwashers, and humidifiersthese systems should be regularly

    inspected and maintained. Dead-end piping, low spots, and other

    areas in the water distribution system where water may stagnate

    during shutdown should be avoided.

    Safety showers/eyewash stationsthese facilities must beroutinely flush tested inaccordance with RIL HSE Standard. Architectural fountainsDrains or sumps should be situated

    at the lowest level of the pool,with no other local low points that

    are not served by drains or sumps. It is recommended that

    fountains be cleaned regularly.

    5.8. Legionella monitoringLegionella bacteria are ubiquitous in the environment; thus, random watersampling often yields positive results. The virulence of Legionella depends on its

    species. Because transmission occurs through aerosolization or aspiration of

    water contaminated with Legionella organisms, special attention should be

    focused on water sources that could become aerosolized.

    Sampling for Legionella may be appropriate if it is carried out for a specific

    purpose. Some examples include

    Verifying the effectiveness of a water treatment protocol.

    Evaluating the potential amplification/transmission sources at a facility. Verifying that decontamination procedures have been effective.

    If an outbreak of Legionellosis occurs, Occupational health resources or aqualified vendor should be consulted for information on proper sampling,

    handling, and shipping methods for monitoring for Legionella in water.

    5.9. MoldMold can be found almost anywhere and can grow on virtually any material as

    long as there is moisture and oxygen. There are molds that can grow on wood,

    paper, carpet, foods, and insulation. When excessive moisture accumulates in

    buildings or on building materials, mold growth often occurs, particularly if the

    moisture problem remains undiscovered or un-addressed. When mold growthoccurs in buildings, some building occupants may report adverse health

    problems, particularly people who have allergies or respiratory problems. It is

    impossible to eliminate all molds and mold spores in the indoor environment;

    however, controlling indoor moisture can control indoor mold growth.

    5.9.1. Prevention of mold growth on building materialsThe following steps can help prevent mold growth:

    Repair leaks (e.g., leaky roof, leaky water pipe, andcondensation) promptly

    Drain and eliminate puddles of water Repair, clean up, or replace wet or tainted materials promptly Dry water-damaged areas and items within 48 hours

    5.9.2. Mold samplingCurrently, there are no established exposure limits for interpreting

    environmental measurements of

    Total culturable or countable bioaerosols (e.g., total bacteria orfungi).

    Specific culturable or countable bioaerosols (e.g., Aspergillusfumigatus).

    Revision 0Aug 2008 Page 18 of 26

    Infectious agents or assayable biological contaminants (e.g.,

    20/25

    Indoor Air Quality RIL Group Standard

    mycotoxin or microbial VOC).

    Sampling is generally not necessary if visible mold growth ispresent. Sampling should be considered if the source(s) of the

    mold contamination is unclear or if health concerns are an issue.Surface sampling may help determine if an area has been

    adequately cleaned.

    Competent individuals with specific experience in designing mold

    sampling protocols, using sampling methods and interpreting results

    shall conduct the mold sampling. Sample analysis should follow the

    analytical methods recommended by the AIHA, the ACGIH, or other

    professional guidelines. (See Section 2 for links.)

    5.9.3. Mold remediation for building materialsIf building materials do become contaminated by mold, the following

    steps must be performed as appropriate when planning and

    implementing mold remediation work:

    Consult the occupational health resource as appropriatethroughout the process for technical guidance and to determine if

    any regulations apply to the work.

    Assess the size of the mold problem and note the type of mold-damaged materials.

    Keep building occupants informed throughout the process. Identify the source or cause of the water or moisture problem. Plan remediation to fit the situation. Select PPE (e.g., respiratory protection, gloves, and eye

    protection).

    Select containment equipment (e.g., polyethylene sheeting andnegative air).

    Select the remediation personnel or team that is qualified toperform mold remediation.

    Fix the water or moisture problem (if it has not already beendone).

    Revision 0Aug 2008 Page 19 of 26

    Clean and dry mold-contaminated nonporous materials (e.g.

  • 7/28/2019 1217595181797 RIL Indoor Air Quality Standard Rev-0 Aug 2008

    Indoor Air Quality RIL Group Standard

    metal and plastic).

    Properly dispose of mold-contaminated porous items (e.g.,drywall, carpeting, and ceiling tiles) that cannot be cleaned.

    Inspect for return of moisture and mold problem followingremediation.

    5.10. Control of other indoor air contaminantsSource control, isolation, improved exhaust ventilation, additional make-up air,

    or other appropriate air controls should be provided for areas where service,

    maintenance, housekeeping, or equipment emissions may result in occupant

    exposure or IAQ issues.

    Some examples of indoor air contaminants include the following:

    Formaldehyde off-gassing from plywood, formaldehyde foam insulation,and particle board

    Ozone from copy machines VOC from paint, glues, and cleaning compounds Carbon monoxide from improperly vented fossil-fuel appliances andgasoline-powered engines Radon from ground underneath buildings Synthetic fibers from deteriorating insulation and ceiling tiles or floortiles (see RIL HSE Standards)

    Asbestos-containing materials and lead-based paints shall be identified and

    removed if deteriorating or managed in place.

    5.11. Facility sanitation and housekeeping.Housekeeping of floors, carpets, and surfaces, including periodic deep cleaning

    and trash removal, shall be provided at a frequency sufficient to prevent

    accumulation of microbial growth and odors. Occupants should dispose of

    perishables (e.g., food scraps and beverage containers) only in designated trash

    receptacles and recognize and promptly report water leaks and visible microbial

    growth.

    The design for all renovated and newly designed facilities should be in accordance

    with ANSI/ASHRAE Standard 622001 and other applicable codes/standards (or

    equivalent standards for non-U.S. sites). Internally insulated ductwork shall not

    be used. Furnishings and construction materials should be selected to avoid

    emissions that could result in IAQ problems.

    Personnel representing the companys interest and who are knowledgeable in

    HVAC shall review the design. This review should address provisions for system

    inspection and cleaning.

    A commissioning inspection that helps ensure that the system has been installed

    as specified, properly air balanced, cleaned, and provided with proper filters and

    drains should be conducted.

    5.13. IAQ compliant - medicalLine management shall help ensure that all illnesses and incidents are reported.

    Employees with possible IAQ health complaints must report them to a RIL OHS

    health-care professional as soon as possible. The occupational illness

    investigation process shall be initiated where appropriate. (See RIL HSE

    Standard 39.) Line management shall help ensure that appropriate workplace

    corrective actions are implemented.

    Health complaints that may be related to IAQ problems should be given specific

    designations. For example, building-related illness is commonly used forspecific medical conditions of a known origin that are traceable to a specific

    contaminant source (e.g., mold or microbial growth). Sick building syndrome,

    on the other hand, is usually reserved for IAQ health complaints for which no

    definitive etiology can be found.

    Health complaints related to IAQ problems may be difficult to recognize because,as a rule, they have no distinctive characteristics. Such complaints may resemblea common cold, a sinus infection, seasonal or perennial allergies, or otherrespiratory illnesses. Although the signs and symptoms could be wide-ranging,the most common are the following:

    Runny nose Nasal or sinus congestion Scratchy or dry throat Cough Shortness of breath

    Indoor Air Quality RIL Group Standard

    Asthma attacks that are more frequent or severe than usual Sinus infections that are more frequent than usual

    Headache

    Irritated or watery eyes Excessive fatigue Rash Possible causal factors for IAQ-related heath problems are numerous,and may include the following:

    Animal dander, molds, dust mites, and other biologicals

    Airborne particles and tobacco smoke Combustion products (e.g., carbon monoxide, nitrogen dioxide, andsulfur dioxide from motor vehicle emissions)

    VOC (e.g., solvents, cleaning agents, glues, and photocopier chemicals);personal-care products (e.g., perfumes and hair sprays); pesticides; formaldehyde

    that may be in particle board, carpet backing, or fabrics; and airborne emissions

    from off-site locations (e.g., industrial neighbors)

    Most of these agents can also be found outside the workplace (i.e., in homes and

    in public places), making etiology more difficult to determine. However, as with

    most work-related illnesses, investigating whether a temporal relationship exists

    is often valuable. For example, if the signs and symptoms are related to workplace

    environment, they usually appear or worsen while the employee is at work and

    disappear or lessen while the employee is at home, especially on the weekends, or

    while away on vacation or on business.
