EcoBioLand www.ecobioland.com CONSULTANCY TRAINING PRODUCTS HEALTH & WELLNESS SOLUTIONS Indoor Air Quality
EcoBioLand www.ecobioland.com O & G Scenarios • Offshore facilities – living quarters turn around of occupant is very frequent, leaving little time to clean and disinfect the environment. • Offshore food storage – food supplies are sent in bulk. (Need to be kept in a clean environment to avoid them from getting contaminated fast). • 24/7 manned control room (must be kept clean/sterilized at all times). • Absenteeism due to health condition - results in reduced productivity.
EcoBioLand www.ecobioland.com On-ground ventilation systems usually follow the (inside) low-pressure principle so that either natural ventilation, or forced ventilation or both (often named hybrid ventilation can be employed. Offshore ventilation follows the (inside) over-pressure principle (positive pressure). The main reason for this is safety, i.e. to prevent any potential ﬂammable gas entering the buildings resulting in recirculated air being used. Offshore/onshore indoor climate/HVAC system
EcoBioLand www.ecobioland.com Issues / problems at O&G facilities Over-pressure principle (positive pressure) • Pressure to be kept 25-50 pa over the outside ambient pressure. • Stale air in:- • Accommodation Quarters • Offices • Kitchen Quarters • Control Rooms Resulting in a build up and habitation of fungus, bacterial, and mold.

EcoBioLand www.ecobioland.com The Facts The USEPA (U.S. Environmental Protection Agency) states that poor indoor air quality is one of the top five environmental risks to public health. Indoor air pollution is a silent threat. You are more likely to get sick from pollution in your home and office than from pollution in the air outside. We actually spend 90% of our time indoors in average. All cleaning and scrubbing only works on surface, air need to be sterilized and disinfected.
EcoBioLand www.ecobioland.com Developments of mold, fungi and mildew Unhealthy environment for the people with allergic problems Spread of airborne related diseases Effects from Poor Indoor Air Quality Exposure to harmful chemicals such formaldehyde from paint and cigarette smoke Long and repetitive illness due to source of disease is not looked into Increase in cost and expenses due to medical fees, cleaning, maintenance
EcoBioLand www.ecobioland.com Code of Practice of IAQ - DOSH DUTY TO CONDUCT ASSESSMENT Every employer should assess the risks arising from the indoor air quality at the place of work to the health of his employees. DUTY TO CONTROL EXPOSURE An employer should ensure that his employees or any other occupants at the place of work are not exposed to any of the contaminants listed in the table below exceeding the corresponding maximum limits. Eight-hour time-weighted Indoor Air Contaminants average airborne concentration ppm mg/m3 Carbon dioxide C1000 Carbon monoxide 10 Formaldehyde 0.1 Respirable particulates 0.15 Total volatile organic compounds 3
EcoBioLand www.ecobioland.com WHO Guidelines on IAQ Eight-hour time-weighted Indoor Air Contaminants average airborne concentration ppm mg/m3 Carbon dioxide 1000 Carbon monoxide 9.0 10,000 Formaldehyde 100 Respirable particulates 0.15 Total volatile organic compounds 0.75 As people spend a considerable amount of time indoors, either at work or at home, indoor air quality plays a significant part in their general state of health. This is particularly true for children, elderly people and other vulnerable groups. The WHO guidelines for indoor air quality, developed under the coordination of WHO/Europe, address three groups of issues that are most relevant for public health: • biological indoor air pollutants (dampness and mould) • pollutant-specific guidelines (chemical pollution) • pollutants from indoor combustion of fuels.

EcoBioLand www.ecobioland.com The importance of testing for Particulate count Particle counters are used to determine the air quality by counting and sizing the number of particles in the air. This information is useful in determining the concentration and micron size of particulates since it has a direct relationship to human well being and IAQA. Testing Method
EcoBioLand www.ecobioland.com The importance of testing for Volatile organic compounds (VOC) Volatile Organic Compounds (VOCs) refers to organic chemical compounds which have significant vapor pressures and can affect the environment and human health. Testing Method
