We had a call form another source claiming to have 'silica free' oil dri as well as their 'normal' oil dri ... this made us ask the question to Peter McNally .... do we need a silica free oil dri
Well -it turns out that we indeed have the safer product ... anything with less than a content 0.1% of crystalline silica and more is NOT subject to the whmis act ... anything that os over this --IS subject to the whmis act
Here are some data from Oil Dri Canada -- your salesman and managers will have the original .doc version is someone wants a paper copy.
===================================
What is crystalline silica?
>>>>>Crystalline silica is one of the most common mineral on earth. The form mostly seen is quartz (beach sand).
What is the regulation concerning the crystalline silica?
>>>>>In Canada, the regulation says that a content 0.1% of crystalline silica and more is subject to the whmis act.
Crystalline silica in Oil Dri floor absorbents?
>>>>>>Even if crystalline silica is a component of the clay, the content of respirable dust is under 0.1% of the total weight. In normal conditions, the naturally-occurring crystalline silica as quartz is in fact below 0.1mg/m3. It is in fact safe to use.
Why a warning on the bag?
>>>>>It is a reminder that it is possible to generate dust in the air while using this product, just like it is possible to be in contact with a solvent while pouring it. In both cases, the answer is to act carefully.
======================================
More information on the silica content of our floor absorbents.
Oil Dri Industrial Floor Absorbent is made of 100% ground clay from Mississippi. It is a natural product. (No additives) An important fact is that clay (floor absorbent) may generate dust. The physical content of respirable dust in the product is under 0.1 % of the total weight.
It is clear that under conditions of normal use, exposure to respirable crystalline silica from this product is below the OSHA Permissible Exposure Limit and the ACGIH Threshold Limit Value.
It is a fact that silica is causing eye and respiratory irritations, like sand at the beach (sand is silica). An adequate ventilation in plant or the use of approved protection will reduce the exposure.
***** We are screening our product at different steps in the process. That technique is reducing the dust content for a safer product. ****** ( starts by GH )
The use of that product will generate less contact with dust then the use of a product like Eagle Pitcher. It is a fact that the hardness of the granule will prevent slaking and at the same time,it will reduce the level of dust generated by attrition. The Eagle Pitcher is generating more dust since it has a lower resistance. (hardness)
List of end-users:
Alcan Canada Hydro-Québec
General Motors Canadair
Bombardier(Valcourt) Monsanto
National Defense ABB
Quebecor Ottawa-Carleton Transit Commission
This is a short list of Oil Dri floor absorbent users.
Just another example of how our product is the higher end product -and that others can always have something cheaper and more dangerous ( less screening to remove dust )
Good selling
