Unless of course you ran your kitchen exhaust in rigid fiberglass duct board or UL mentioned factory created air duct there would not be described as a need for using UL 181A or B labeling on the metal tape.
The commonest of those sorts is calcium metasilicate, for which details are supplied earlier mentioned. Calcium silicates Together with the formulation Ca2SiO4 and Ca3SiO5 can also be renowned.
The mention of names of certain firms or products isn't going to indicate any intention to infringe their proprietary rights.
Ca2SiO4 is normally viewed as Risk-free to be used in various programs, like design supplies, insulation, and meals additives. Nevertheless, extended or too much inhalation of Ca2SiO4 dust may irritate the respiratory program. Skin and eye connection with Ca2SiO4 may additionally irritate.
The code is not really fully distinct wherever it states ducts "connecting inside of" eighteen" with the hood shall be non-combustible. Does "connecting inside" necessarily mean "connecting to" ?

investigated the effects of different anticaking brokers, together with calcium silicate, and located no sizeable health risks related to its consumption at amounts commonly Utilized in foodstuff products. From the realm of occupational wellbeing, extended exposure to pure calcium silicate, specifically in industrial options, can pose hazards. According to the Materials Protection Facts Sheets (MSDS), inhaling airborne particles may result in respiratory tract irritation. Having said that, it is important to differentiate this situation from the dietary presence of calcium silicate - in our kitchens and on our plates, the quantities are vastly lower rather than aerosolized, glasswool insulation hence posing small wellbeing pitfalls.
