The importance of indoor air quality in the oil and gas industries

the evidence of absence

O & G SCENARIOS

• Offshore facilities – living quarters turn around of occupant is very

frequent, leaving little time to clean and disinfect the environment.

O & G SCENARIOS

• Offshore food storage – food supplies are sent in bulk. (Need to be

kept in a clean environment to avoid them from getting

contaminated fast).

O & G SCENARIOS

• 24/7 manned control room (must be kept clean/sterilized at all

times).

O & G SCENARIOS

• Absenteeism due to health condition - results in reduced

productivity.

ventilation

• Positive pressure

• Safety

• recirculated air

being used.

OFFSHORE/ONSHORE INDOOR CLIMATE/HVAC SYSTEM

Pressure to be kept 25-50 pa over the outside ambient pressure.

ISSUES / PROBLEMS AT O&G FACILITIES

Over-pressure principle (positive pressure)

Stale air in accommodation Quarters, offices, kitchen Quarters & control

Rooms

Resulting in a build up and habitation of fungus, bacterial, and mold.

Pressure to be kept 25-50 pa over the outside ambient pressure

STALE AIR!

ISSUES / PROBLEMS

Offshore living quarters with IAQ issues / problems

• Poor ventilation

• Stale odor

• High turn around

of occupant - hard

to keep it clean

ISSUES / PROBLEMS

Control rooms / office etc. with IAQ issues / problems

• Poor ventilation

• Stale odor

• Contamination from

occupants

THE FACTS

The US EPA (U.S. Environmental Protection Agency) states

that poor indoor air quality is one of the top five

environmental risks to public health.

THE FACTS

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.

THE FACTS

We actually spend 90% of our time indoors in average.

THE FACTS

All cleaning and scrubbing only works on surface, air need to be

sterilized and disinfected.

Spread of airborne related diseases

EFFECTS FROM POOR INDOOR AIR QUALITY


Exposure to harmful chemicals such formaldehyde from paint and cigarette

smoke

Developments of mold, fungi and mildew



Long and repetitive illness due to source of disease is not looked into

Unhealthy environment for the people with allergic problems



Increase in cost and expenses due to medical fees, cleaning, maintenance

EU & WHO AIR QUALITY GUIDELINES

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:
