  • A very good comment! Thank you. I so agree, a worker, and an employer, cannot handle the risks properly before they really understand the risks and the possible implications of the exposure.

  • Very nice comment, discussing many aspects of this case. Thank you :)

  • This is true, but there are also many possible measures to do to reduce the noise exposure towards the workers. Even a simple thing like distance and work technique can have large effect on the actual noise level dose.

  • Hello! Welcome

  • What alternative methods would you suggest in this situation?

  • Thank you for the reply. As my fellow educator commented elsewhere also these "quick-solutions" also happens many places as you also write. Building sites are difficult to control and are of varying sizes and numbers adding to the difficulty. We hope by spreading knowledge we add a little bit to the safety of work places :) Thanks again for good contributions...

  • Thank you for your answer. In cases involving radiation exposure, the best way of reducing the exposure is reducing the exposure time or increase the distance from the source. In this type of work often the time using "live" radiation is probably possible to reduce. Another important aspect is rotation of workers and doing the procedures strictly when it is...

  • Welcome to the course :)

  • Important note and not easy to answer. But a small improvement is also an improvement, even though we might not get to full power mask at once, many of the challenges can be handled better through better information, education and simple efforts.

  • Thank you for the comment, I agree, it is difficult, but important to reduce noise exposure and raise awareness about the health effects of noise

  • Thank you for a nice comment, another important risk when there is a lot of noise is the risk of accidents. You may not hear the warning signal and so on and therefore be at a higher risk.

  • Nice comment. There is always an issue with exposure that leads to risk over time and not suddenly. Awareness is superimportant.

  • Yes, very important note. Also as you stated, sometimes the use is necessary for different reasons, but then even more important to be handled correctly and safely.

  • Thank you for many good comments. Regarding chronic health effects from organic solvents. Yes, there is a big chance of late detection. Often other illnesses and attemps of treatment are done before the investigation into solvent exposure becomes an issue. And often the treatment have little function because the patient still is getting exposed. Therefore we...

  • Agriculture has a lot of hazards in both equipment, chemicals and biological hazards to mention some. In addition the occupation is at risk as the farmers often work alone and therefore is more at risk if an accident happens.

  • Agreed, its important to inform/educate the workers about thus. One way is at work, but also important to include in theveducation.

  • Nice discussion, showing that the views are divided and varies with how you define the workers and the employer. This, in my view, shows the challenges when the responsibilities are not clearly defined.

  • Most important in my view is, as some has stated in this discussion, to not work during the hours with most intense radiation (this varies with region). Work in the shadow is also good, and sun-screen protection cream if available.

  • I think this will vary both with type of work, outdoor conditions and so on and needs to be addressed specifically in every setting. Qualified personnel should consider the hazards in the work and duration and from this consider the length of the shifts.

  • I agree, the basic rules for hygiene are the most important! The different PPE and others are "only" additional barriers, but still the basic rules of hygiene must be in place.

  • The pandemic of COVID19 is a really big challenge all over the world, and the focus on biological factors have never been higher

  • Great work everybody! It is very nice to see how well you discuss and answer the different sections. A lot of motivation for us as course leaders!

  • Thank you for a nice comment. Much appreciated.

  • This is the same in Norway also

  • Thank you for your question. Light therapy is about moving the biological clock. The biological clock is set every day when we wake up and opens our eyes to light. This may be disturbed both at shift work, when travelling over time-zones and if one has a habit of going to bed at odd hours, and sleeping long. By giving light (at correct times) we can shift this...

  • Thank you all so far for many good comments, I agree that it is of course important that she tells the man first and tries to solve the matter. If not I also think that it's important to not give up. Talking to a friend, collegue, reporting to your manager and so on. This will depend on different handling in different countries. But first of all in my mind is...

  • wonderful to read! Thanks for participating!

  • I agree. In regards to reporting structure, if the harrassing colleague is a colleague it should be reported to your manager. If the report is not dealt with, or the harrassing colleague is your manager you should be able to report at the next level. When all this fails cases appear as "whistle blowing". Thank you for good comments!

  • Very nice comments everybody, you discuss different solutions and it is interesting and nice to read! Thank you all for making this course great!

  • sad but true in many parts of the world

  • A very nice comment, I agree completely :)

  • Just as a curiosity, the way the bag is transported in the film. Can it be done in that way but in a much safer way? Or would you demand that they change the way the move it completely?

  • I agree. The aim and reporting and rewards can even become dangerous. For instance, imagine that the company sets a bonus to all employees if nobody has an accident for one year. This will put pressure one the one actually having an accident not to report it, because they will not be the cause of the missed bonus. Therefore the worst thing I see are building...

  • Very nice comment, agree.

  • Thank you for good answers, there is of course a problem that these workers are not employed. But the mine owner in my mind has a clear responsibility since he is benefitting from the work, and he owns the mine (the exposure). Therefore in my mind I would say he needs to adress this issue, but of course this is depending on local laws and regulations.

  • Thank you for many nice comments and discussions, I agree of course with you all. It is not ok to "produce" deaf workers, but I also think as many of you that if the workers dosen't really understand the reason for the protection they will not use it. Therefore PPE should be the last thing to reduce noise exposure, and focus should be on removing the hazard,...

  • agree

  • Agree, and they often function very well and can give a good idea on what the noise levels are, even though they are not as stable as "real" noise meters... :)

  • Yes, noise levels may exceed these recommended limits in many places outside work. Here it is often the government and the society which has to consider this exposure in relation to the personal freedom we also wants (for instance rock concerts etc)

  • Thank you, but remember that a "small" reduction in dB levels may have a dramatic effect due to actual reduction in the physical noise level (pascal) :)

  • I would instead of medical check as a prevention, focus on reducing the load/stressor for each worker. Example by helping aids (cranes, fork-lifts and so on), sharing the load on more workers etc etc. Reducing ergonomic stressors.

  • Yes, there are many products with the same effects as asbestos, asbestos is banned from more than 55 countries in the world, but the price I am not sure about, it may be a problem that asbestos is cheap and easy to get delivered.
