Indoor Air Quality Risk Communication:
Before You Fix Anything, Talk!

This is the fourteenth in a series of risk communication columns I have been asked to write for The Synergist, the journal of the American Industrial Hygiene Association. The columns appear both in the journal and on this web site. This one can be found (more or less identical except for copyediting details and a couple of cuts for space) in the August 2007 issue of The Synergist, pp. 52–54.

One of the most daunting risk communication problems managements routinely face is a rash of employee complaints about indoor air quality (IAQ). Whatever the presenting symptoms – headaches, nausea, actual rashes, or even the dreaded Multiple Chemical Sensitivity – the possible consequences are dire. More than one building has had to be abandoned altogether because its occupants flat-out refused to return. More than one jury has returned big-money judgments to compensate plaintiffs for the presumed impacts of a “sick building.“

How you communicate with affected people may well determine how – or whether – an IAQ controversy gets resolved.

Real Problems, Psychogenic Symptoms

IAQ risk communication is grounded in this basic conundrum. On the one hand, most buildings have real IAQ deficiencies. On the other hand, most IAQ complaints are largely psychogenic. As the U.S. EPA has famously said (it’s a quote used to sell home air purifiers), the air inside the average house is dirtier than the air outside. Office and factory air can easily be dirtier still. You know the main culprits better than I do – from mold to VOCs to HVAC inadequacies. Your facility can meet all the relevant OSHA standards and still have a long list of ways air quality could be improved. Even if the air isn’t actually “bad,” it is almost always bad enough to make some employees’ symptoms (and other employees’ worries) credible on their face.

But there are similar air quality deficiencies in buildings that never experience IAQ complaints. Certainly poor air quality leads to more symptomatic employees than good air quality. But in my experience, three other factors are also important in determining how much IAQ controversy you’re likely to face:

The worst response: Management says nothing publicly, appearing to be paying no attention. Meanwhile, it quietly brings in an expert to identify and fix as many IAQ problems as possible – at least the cheap ones. When employee complaints fail to subside, management belatedly decides to go public. It makes a show of testing air quality (again), points out that everything looks pretty good (now), and implies that employees with symptoms must be troublemakers, malingerers, or nutcases.

By contrast, IAQ controversies are likeliest to go away if management takes the precipitating event and the early complaints very, very seriously. Worry with your employees. Worry more than your employees. (This is the risk communication seesaw; the more worried you let yourself look, the calmer everyone else is likely to get.) Ask employees what they think might be behind their symptoms, and then look there first. Some of the possible problems employees point to will inevitably turn out to be genuine deficiencies. They may or may not account for the symptoms (odds are you’ll never know). But they’re not too hard to fix. So fix them – publicly, with lots of fanfare and employee oversight. Express guarded hope that maybe you got to the root of the problem, and determination to find some more things to fix if the first batch didn’t do the job.

Talk First, Fix Later

The obvious truth we tend to forget: A “secret” IAQ improvement can correct only the technical part of the problem. But a public improvement – especially a public improvement employees suggested and predicted would help a lot – addresses the psychological part of the problem as well. So talk before you fix anything.

I’m not saying you should just let your building’s air quality deteriorate until employees finally get around to demanding improvements. Of course it’s wise to maintain IAQ at as high a level as feasible. But whatever your level of maintenance, when the IAQ complaints start to surface, don’t rush out and secretly do a bunch of upgrades without telling (or asking) anyone. Visible responsiveness is a key to resolving the psychogenic component of IAQ controversies. Eventually you’ll probably end up fixing some things that employees are demanding you fix. Try to reach that point before you’ve already fixed everything that isn’t terribly expensive and everything that is actually likely to help technically.

The following additional tips on IAQ risk communication aim to help you address the psychological side of indoor air quality as well as its technical side – “as well as,” not “instead”!
