Are you considering using blackboards for a homeschool? Or do your children attend a school that uses blackboards that require the use of chalks? Here is what you need to know before you make a decision.
As paramount as the education of your kids may be, ensuring that they are also healthy is even more important.
Children have immune systems that are still in the process of development. This means that there is a higher chance that some substances that may not affect a healthy adult could result in serious issues for them.
The answer to whether chalk dust could pose a health concern to your kids is a simple “yes,” and if you want to know why that is, you should follow me through the article.
Possible Dangers of Chalk Dust
Writing with the chalk may not pose any threat, since the majority of the dust is glued to the blackboard. The actual problem begins the moment the blackboard gets wiped with a duster.
The dust that was formerly on the blackboard gets wiped, and the dust now is trapped in the air for a while before it falls to the ground. Now imagine in an enclosed classroom with about 20 students that have to breathe or interact regularly, how much of that dust would they have in their lungs before school hours are over?
It is easy to worry about the kids, but the person who is at a greater health risk is the teacher who stands close to the blackboard and talks all day long while teaching the kids.
There are several chalk dust health concerns that could eventually result in more serious issues in the long run.
Naturally, chalks are nontoxic, a long term inhalation and exposure would create a mold of the dust inside the respiratory system, and organs such as the lungs and throat. This may not pose any immediate threat of challenge, but in the long run, it could lead to something much worse.
Some health problems associated with inhalation of chalk dust include lung problems, which occur as a result of clogged airways; asthma in kids with milk allergies; it can result in some skin rashes if the child is directly exposed to it.
In recent times, there have been developments in schools and training centers. More and more people have begun to realize that it is much better to take precautions than to allow something they’re not totally sure of to ruin their breathing.
Both public and private schools have now chosen better alternatives and are surely not going back on that.
Some better alternatives to blackboards include the use of magnetic whiteboards on which you can easily write with a disposable marker and erase with ease; canvas; desire to learn, also popularly known as D2L; presentation lectures using MS PowerPoint; among a variety of other ways.
In conclusion, chalk dust on blackboards may not really pose a big health issue, since the chalk is made of natural substances. What this means is that you shouldn’t have chalk dust health concerns if you are only exposed to it once or twice. The major problem comes when this exposure is constant like in a classroom.
