Old MSDS Sheets related to Manganese in Welding Rods

You were not forced to continue with your job. You could have demanded protection and quit if it was not forthcoming. Workplace environment effects on health and well-being are simply one of the many characteristics of any job which should be evaluated when choosing a job. If people approached life more often in this manner, then those riskier jobs would either have to pay more compensation and/or give more protection or they would not find employees willing to do the work. Furthermore, not supplying protection should not be grounds for a lawsuit only concerning fraud to the extent that the employer specifically gave you false information. He did not chain you to your work place and force you to stay there and work under under conditions.

Each person is responsible for himself and every individual needs to constantly look out for his own welfare, since no one else can know sufficiently what is his welfare (only he can truly know himself) or has the direct self-interest in doing so.

If your situation is not too bad, there are therapies which can help. It is never too late to begin their investigation.

So, what sort of exposure is dangerous? I weld less than 1 lb. a week (probably less than 1 lb. a month) of stick as a hobbyist; am I in danger of manganism?

What sort of respirator is adequate for this level of exposure -- is a particulate mask sufficient, or does one need something more?

At most you need good ventilation. The amount of welding your doing is insignificant.

The "Official" OSHA threshold limit for Magnesium Fume Particulate is 15 parts per cubic meter.

A pound of rod isnt anything. Near that. Although that is guessing on my part.

A particulate mask wouldnt hurt in any case.
