Need some assistance from all the experts out there on dust.
I have an issue where during an activity processing cardboard it generates dust.
The activity is not cutting the cardboard, just putting smaller bales of cardboard into a baler and turning it in Mill sized bales.
I am going to arrange some testing however:
At the end of the shift you can see dust has settled onto the machines
I am getting complaints (New Process) and have provided Dust Masks as an interim measure
How hazardous is paper / cardboard dust?
The area has open doors - FLT access so has some general ventilation, is this sufficient?
Want to make sure I am on the right track.
Thank you in advance

Being an ex paper-maker there are Work Place Exposures listed for paper fibres of 10mg/m3 inhalable and 4mg/m3 respireable 8hr TWA - COSHH regulations and assessment kick in.
For most equipment with the capability of generating dust (slitters / re-winders / re-pulpers) we had Local Exhaust Ventilation Systems installed with sealable extraction bags.
On the main pulper in the recycled plant the plume of dust from bales landing in the process were supressed by a process water curtain.
I don't think damping down is an option as your bales are sold on weight and excessive moisture is penalised by the recovery company, as well as being frowned upon by the mill due to its promotion of microbial activity that may result in combustion especially over the summer months.

OK OK I know it's not exactly the same - but this advice might be a good starting point?
Unfortunately I don't have time to go into WELs and principles of control, I'll leave that for others :)
