The Occupational Safety and Health Administration recently published Hexavalent Chromium, a booklet outlining industry requirements for hexavalent chromium standards.
Inhaling the chemical’s fumes can cause allergic reactions or asthmatic symptoms, such as wheezing and shortness of breath. The booklet explains OSHA’s hexavalent chromium standards in a reader-friendly format and is a companion document to the Small Entity Compliance Guide for the Hexavalent Chromium Standards published in 2006.
Under the Occupational Safety and Health Act of 1970, employers are responsible for providing a safe and healthful workplace for their employees. For individual courses, the PDF certificate is only $13, the original certificate is $17 (shipping extra), and the PDF & original certificate is $22 (shipping extra).
After you have studied all of the course material and taken the module quizzes, you can take the final exam.

Who should investigate?Many people may play a role in helping to resolve an IAQ problem including the building owner, employer, property manager, and occupants.
What should I do if I suspect that I am ill from poor IAQ?If you think that you may be ill from IAQ problems, it is important to keep track of when you get your symptoms (aches, pains, headaches, etc.) and when they go away. Workers exposed to this toxic chemical can develop lung cancer and damage to the nose, throat and respiratory system.
Hexavalent chromium is used in pigments, metal finishing, wood preservatives and fungicides.
Requirements for exposure limits, exposure monitoring and determination, protective work clothing and equipment, medical surveillance, communication of hexavalent chromium hazards and recordkeeping are described. Is indoor air quality (IAQ) a health and safety concern?Indoor air quality has become an important occupational health and safety issue. Who conducts your investigation will depend on your workplace, but in general, you should have one person who is the leader, and perhaps a small team, including a representative from the work site health and safety committee, or the union, if appropriate.
This record will help your safety officer or health professional determine what the problem is related to. These mites tend to exist mostly on mattresses, bedding, upholstery, and carpet, as well as other objects like stuffed animals and drapes. Workers may also be exposed to hexavalent chromium fumes generated during welding of chromium metal alloys. In the past few decades, energy conservation measures have led to airtight building construction that can create problems with IAQ. Dust mite populations are also higher in more humid climates than dryer ones.And since dust is partly made up of living organisms, there are health risks of dust mites you should be aware of.


Frequently the ventilation systems are set to minimize the amount of fresh air entering and circulating within the building. Some people are more sensitive to dust mites than others, but those who are allergic to them can develop life-long health problems ranging from mild to severe. This restriction impacts indoor air by allowing a build-up of air contaminants within the building that are not properly removed.People spend a lot of time indoors -- for example, many office workers will spend their entire working day inside buildings. People working indoors often experience symptoms such as headaches, shortness of breath, coughing or nausea just to mention a few. If you are allergic to dust, the first thing you should consider is altering the environment inside your home. However, it is rarely possible to prove that these symptoms are related to a particular indoor air contaminant. Wall-to-wall carpet is one of the leading causes of excess dust in the home, so rip it out if you can. In fact, building occupants are simultaneously exposed to a wide range of indoor air contaminants.What are the common causes of IAQ problems?IAQ problems result from interactions between building materials and furnishing, activities within the building, climate, and building occupants. Dust clings to carpet fibers, and every time you walk across the floor, the dust is kicked up and spreads. We were fortunate to have hardwood floors under our old carpet, so we took all of it out and now just have a few low-pile area rugs on our hardwood.
This has significantly reduced the amount of dust in our home.Other large items that should be changed or removed in your home are upholstered furniture (opt for leather, vinyl or wood instead) and drapes or heavy curtains (consider easy-to-clean blinds or shutters).
However, no specific illnesses or cause can be identified.Building-Related Illness (BRI) refers to less frequent (but often more serious) cases of people becoming ill after being in a specific building at a certain time. Switching out our upholstered sofa for a leather one and using wooden blinds has reduced dust and made cleaning easier. In these cases, there is usually a similar set of clinical symptoms experienced by the people and a clear cause can often be found upon investigation. Eliminate excess clutter that dust can cling to, especially piles of stuffed animals, dirty clothes and other objects with fibers.
We have air purifiers in almost every room of our home equipped with HEPA filters, as well as a HEPA filter vacuum, which keeps dust contained instead of putting it back into the air.But the best thing you can do to decrease the health risks of dust mites is to regularly clean your home, especially the places dust mites like to live.
However, medical opinion is divided, and further research is needed.Is air contamination the only cause of these symptoms?No.
Feelings of discomfort and illness may be related to any number of issues in the total indoor environment. Carpet should be vacuumed every day in heavily trafficked areas, every other to once every three days in less-traveled areas of the home.However, the best way to eliminate dust is by removing it from surfaces twice a week.


Other common causes may include noise levels, thermal comfort (temperature, humidity, and air movement), lighting, and ergonomics. Feather dusters tend to just move the dust around; instead, try microfiber cloths since dust will cling to these. A clean cloth and dusting spray will also work to remove dust from surfaces.The fastest way to dust a room is to use a disposable duster.
Some people may be exposed to more contaminants in the building than others and they may experience symptoms earlier than other people.
These synthetic dusters are simple and quick to use, since you don't have to remove knickknacks and pictures, but can instead dust easily around them. These dusters can also be purchased in a starter kit with an expandable handle, so you can dust the tops of picture frames, ceiling fan blades, door moldings and other hard-to-reach areas with ease. Some people may not be sensitive to IAQ problems in the early years of exposure but can become sensitized as exposure continues over time.When should I start suspecting that IAQ may be a problem?When there is a problem with IAQ, people may experience various health conditions that are listed above. Since many of the symptoms are very similar to what we feel like when coming down with a cold or the flu (influenza), it is often difficult to say for sure if indoor air is the cause of the symptoms.However, it would be prudent to investigate IAQ if people develop these symptoms within a few hours of starting the workday and feel better after leaving the building, or after a weekend or vacation.
In addition, if many people report similar symptoms, or if all of the people reporting symptoms work in the same area of a building, air quality should be suspected.Are there laws or guidelines for IAQ?Many Canadian jurisdictions do not have specific legislation that deals with indoor air quality issues. This clause, common to all Canadian occupational health and safety legislation, states that an employer must provide a safe and healthy workplace. In the United States, the Occupational Safety and Health Administration (OSHA) has compiled information on Indoor Air Quality.In addition, IAQ is implied in most building codes as design and operation criteria.
So these values tend to be lower than regulatory values that are set to protect workers from possible health based hazards.*We have mentioned these organizations as a means of providing a potentially useful referral.
Occupational exposure limits listed in health and safety regulations and the Threshold Limit Values® (TLVs) recommended by the American Conference of Governmental Industrial Hygienists (ACGIH) are intended as a guide to prevent illness or certain effects (like eye and nose irritation) in industrial situations.
These limits may not be appropriate in office settings or for the home.Occupational exposure limits use dose-response data which show the health effects of repeated exposure to one specific chemical.
Similar data is not available for long-term, low-level exposures to a combination of contaminants as is the case for IAQ problems.
Currently, there is not enough information available to predict the effects of exposure to several potentially harmful agents at the same time.How do I investigate possible IAQ problems?Typicaly people will report that they are experiencing symptoms believed to be caused by IAQ.
