good luck with the healing J. kick the mrs's tush and get the cab! Im lucky in the respect that she is the one with asma and bad alergys. In order for her to be able to mow while I am out or run the heaying equipment there must be a cab. In my case masks are worthless. I can't get a baby clean shave due to sensitive skin. i start looking like an alergic bee sting victom. due to that it kinda works to ware a mask but not realy.
To those who need the face protection, it may sound weard but will be your best allaround bet. the head piece from a positive presure suit or one that is made for a resprator. ie the 2' plastic bubble for the head. I plan to get a full suit in the near future for fuel production as well as some other endevers I am intrested in and that I plan to garontee no sickness in the family from. it may seem like overkill but emphazema and others are nothing to mess with. I am going to have to figure out if my tractor has hepa rated ac filters. if not Ill be making or aquireing them.
Msds's really dont cut it they may have done studys of this and that but real 20 year studys have not ben completed on most products out today. so there is no real garontee about them.. also the combination factor. I dont plan to spend my golden years in a bubble I preferr to make the changes now to keep it from being then.
