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

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:

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.

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.
7/28/2019 1217595181797 RIL Indoor Air Quality Standard Rev-0 Aug 2008
17/25
Indoor Air Quality RIL Group Standard
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
7/28/2019 1217595181797 RIL Indoor Air Quality Standard Rev-0 Aug 2008
18/25
Indoor Air Quality RIL Group Standard
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.

7/28/2019 1217595181797 RIL Indoor Air Quality Standard Rev-0 Aug 2008
19/25
Indoor Air Quality RIL Group Standard
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.,
7/28/2019 1217595181797 RIL Indoor Air Quality Standard Rev-0 Aug 2008

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).

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.

Indoor Air Quality RIL Group Standard
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

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.
