It probably should be a glass bulb sprinkler. Not sure if the solder has any magnetic properties Todd G Williams, PE Fire Protection Design/Consulting Stonington, CT 860-535-2080 (ofc) 860-553-3553 (fax) 860-608-4559 (cell) > > On Nov 13,

Listed Upright For MRI

I have a closet located in an MRI room that requires an upright sprinkler. I was asked if the upright sprinkler was listed for use in an MRI enclosure (like some concealed pendent sprinklers). I have no idea, but I don't see why a standard spray brass upright couldn't be used in this closet. It

RE: Listed Upright For MRI

I would have just sent a standard spray glass bulb upright and wouldn’t have thought twice about it. The question was asked by one of our junior designers (good for him for thinking about things like this) and now he has me second guessing what I have done in the past (damn him for thinking

Re: Listed Upright For MRI

Pallet storage above overhead doors

It is realized that warehouses generally are passively safe to workers because of their relatively long smoke filling times. But, fires in pallets, and even more extreme, plastic pallets, will accelerate EXTREMELY fast. FAST. LIKE. 60 to 180. SECONDS. FAST to top of storage after established

Pallet storage above overhead doors

We are working on a project where the tenant wants to store pallets above the overhead loading doors to a height of 6'-0" in the loading dock area.. The project will be using Factory Mutual data sheets, so I went to DS8-24 Idle Pallet Storage and because they are on racks it send me to DS8-9
