Cancer In The Workplace: Soil Contamination’s Lingering Danger.
This is the fourth in our series on how workplace health and safety issues can elevate cancer risks, and how to control potential problems. This article focuses on soil pollution.

One thing about many cancer-causing toxins used by industry: The risk continues long after they have injured or killed workers. A prime example is the solvent used in paint. A key ingredient is something called “2-nitropropane.” Not only can brief, unprotected exposure to it kill people, once it enters the soil it stays there for hundreds of years.
For example, two construction workers became ill recently after applying an epoxy resin coating containing 2-nitropropane in the confined space of an underground concrete vault. One man died 10 days later and although the second man recovered, he has had persistently elevated levels of a harmful serum in his pancreas. These cases show the importance of both effective industrial education and protective work practices.
Even non-industrial toxins can be deadly.
For example, The New England Journal of Medicine reported 25 years ago that radon, a common radioactive gas emitted by soil, stones and most building materials, may be responsible for as many as 10,000 lung cancer deaths among non-smokers in the United States each year. Follow-up studies reveal nothing to contradict the original findings.
Thus, industry must take special care not to add to the problem – and to ensure that workers are adequately protected as well as minimising the risk of contaminating soil.
Many Potential Sources
A large number of industrial processes use toxic material directly, or employ materials that contain toxins.
These can range from arsenic and PAH’s such as benzoapyrene to garden variety diesel oil products.
Diesel oil can be especially deadly if mishandled. Frequently, soil testing at industrial sites find that the contamination levels from petrocarbons – often diesel products – greatly exceed guidelines mandating clean-up. The International Agency for Research on Cancer (IARC) has determined that occupational exposure to fuel oils are probably carcinogenic in humans based on animal studies suggesting that repeated contact seems to cause liver and skin cancer.
If diesel products leak into the soil, the cancer-causing by-products take hundreds of years to disappear, spreading their deadly impact into residential areas and farms where they become part of the food chain.
Other heavy metals commonly used by business cause a range of medical problems, both when unprotected workers are exposed as well as if they contaminate the soil around an industrial site. These include heavy metals such as zinc, barium and cadmium – very common in industry – as well as polycyclic aromatic hydrocarbons such as benzoflourantheme.
Studies indicate that soil contaminated by these minerals and compounds can lead to so-called “cancer clusters” both in the workplace and surrounding communities. A cancer cluster is defined by doctors as “(an) aggregation of relatively uncommon events or diseases in space and/or time in amounts that are believed or perceived to be greater than could be expected by chance.” Many instances brought to the attention of health and environmental regulators are “occupational” in that patients in a cluster are identified in terms of their workplace.
Costly Problems, Inexpensive Prevention
Controlling soil contamination from the workplace and in the surrounding community can be a complex problem. When a hazard is discovered, the clean-up cost is enormous to say nothing of potential expenses resulting from worker illnesses, community problems, fines and lawsuits.
Still, there are ways to minimize and even eliminate the risks:
· Worker education is the always first step to ensure that employees understand what they are dealing with and how to prevent potential problems.
· Ensure that toxic material is stored properly in appropriate sealer containers or rooms.
· Install self-contained treatment filters to capture inadvertent spills and run-offs.
Some of this is simply common-sense, some is already required by law and some – such as installing plant site water treatment facilities – is under serious consideration by regulators. A workplace audit where risks are involved will reveal ways to minimize potential problems.

Cancer In The Workplace: “Safe Enough” Can Hide Dangers.
Cancer In The Workplace: “Safe Enough” Can Hide Dangers.
This is the third in our series on how workplace health and safety can elevate cancer risks, and how to control potential problems. This article focuses on hidden cancer dangers lurking in occupation safety issues.

Only a madman or a fool would work with dimethyl sulphate without wearing a certified safety mask to protect against inhaling its lethal fumes.
Yet even a conscientious employer may not spot hidden dangers in what is otherwise thought of as a “safe” plant.
Not long ago, a company brought us in to conduct a thorough compliance audit in an attempt to hold the line of its insurance premiums, which the insurer was threatening to hike. As we walked through the facility, the chief operating officer pointed proudly to the numerous health and safety measures the company had installed over the past few years. When we came to a sealed part of the plant where dimethyl sulphate was being used, he began telling me about how insistent the supervisors, managers and executives are about workers being masked at all times.
That’s when I grabbed the man’s arm and pulled him hard towards the exit. Shocked and surprised, as I tugged him away he gave me one of those “are you nuts or something?” looks that comes from disbelief and what, to him, was my incomprehensible behaviour. Once we were safely outside the workspace, I removed my mask and told him, “That place is a breeding ground for cancer.”
What caused me to backtrack so rapidly was the stunning sight of a half dozen workers, all wearing proper breathing apparatus, yet some were working in short sleeved shirts and none wore adequate eye protection. I pointed out that regardless of how powerful the ventilating system is in the room, particulate-sized carcinogens from dimethyl sulphate can enter the body through the skin and eyes.
Never Safe Enough
Needless to say, the COO who was so proud of what his company does to protect workers was stunned. He admitted that it never occurred to him or anyone else at the factory, whether shop floor workers or corner office executives, that they were unknowingly creating a risk despite their sincere, best efforts to create and maintain a safe workplace.
The problem is that dimethyl sulfate and many other common chemicals used in a number of manufacturing processes can cause severe external burns when skin contact is made and damages internal organs if it enters the body through the skin. As a result, strong ventilation systems and individual breathing apparatus for workers are not enough to remove the danger.
Consequently, anyone working around such compounds needs more protection including overalls, and goggles. The entire workplace should be fitted with a spill contamination system. In fact, the government lists 60 precautions that companies need to undertake. Some of these include:
· Always keep the material locked inside proper storage containers when not being used.
· Always store according to MSDS.
· Keep the material away from break rooms and cafeterias.
· Store containers in a well-ventilated place.
· Be sure that ignition sources are kept far from the material.
· Never eat or drink when using the compound.
· Whenever leaving the work area, remove clothing that may be contaminated.
· If a worker begins to feel ill, seek medical advice immediately.
· Follow the manufacturer’s recommendations on recycling.
Real Risks
The risks from dimethyl sulphate and other cancer-causing chemicals are very real yet the dangers can be totally hidden – even from companies that believe they are taking care to protect vulnerable workers.
When so many types of protection are relatively inexpensive and easy to use, there is no excuse for a business of any size not to ensure that workplace health and safety issues are thoroughly addressed.

Cancer In The Workplace: Airborne Workplace Pollution Can Be Hazardous To Living.
Cancer In The Workplace: Airborne Workplace Pollution Can Be Hazardous To Living.
The first in our series on how workplace health and safety can cause hazards, and how to control potential problems. This article focuses on air pollution.

Even though the number of previously-fatal cancers is diminishing as medicine finds effective ways of treating them, they are still a serious enough problem for businesses to consider ways of minimizing them in the workplace.
Admittedly, some exposure from sources such as UV radiation and smoke may occur in both work and non-work contexts. Moreover, there is no way to reliably differentiate between cancers in the same organ caused by different factors. Estimating the extent of occupational cancer is complex and estimates vary according to the method used. Still, it is probable that up to an estimated 11% of cancers are attributable to occupational exposure.
Still, as data collection widens and more is learned about the long-term impact of exposure to carcinogens, it is likely that within the next three-to-five years Ontario businesses will come under increasing pressure to minimize risks.
Proactive Steps
Already, businesses have a legal, pro-active requirement to eliminate workplace hazards so the regulatory framework for broadening the scope to include carcinogens is in place. Indeed, some businesses already work with stiff, cancer-related regulations: For example, printing companies using UV inks, which can cause cancer upon contact, must take steps to ensure workers are protected adequately and report incidents if they occur.
At the same time, chemicals in the workplace whether for personal hygiene or used in the workplace saturate the air. In a recent case, a worker complained about strong scents coming from co-workers. A supervisor requested a supplier provide information about a space deodorant used in lavatories, discovering a possible link between adverse negative health effects and chemicals commonly found in the space deodorants. A simple search for alternatives with fewer harmful chemicals produced substitute options to replace the more harmful space deodorant being used.
As with other hazards, ensuring that workplace exposure to carcinogenic agents does not occur is the best way to reduce occupational cancer. Options range from replacing known carcinogens to the use of enclosed systems and protective clothing.
What researchers are looking for are so-called “cancer clusters.” These happen when reporting of an unexpectedly high incidence of cancer shows up in a defined population or geographical area – such as a manufacturing plan. Some cancer clusters are suspected of resulting from occupational exposure because they are identified with workers in a particular location. Cancer cluster investigations seek to identify unrecognised exposure to known carcinogens and the adequacy of protective measures.
Avoiding Problems
With or without regulations, there are a number of practical, low-cost ways for businesses that deal with potential, cancer causing material can take:
· Ensure workers use eye and face protection if aerosols or splashes are anticipated.
· Use mechanical devices for all pipefitting procedures to prevent contaminated air from seeping into the workplace.
· Make sure that materials that may generate an aerosol is kept in suitable containment devices such as a fume hood, biological safety cabinet, or glove box.
· Capture vapors or aerosols through exhaust ventilation at the worksite, using a fume hood or biological safety cabinet.
· When moving carcinogens in hallways or corridors, make sure they are stores inside a secondary container that seals closed and is leak-proof.
· Place a door card warning at entrances to work areas.
Much of this is simply common-sense and some is already required by law. An audit of a workplace where there might be a cancer risk will reveal whether additional protection is needed.
