Most intumescent fire retardants reduce the amount of potentially toxic gases released in a fire.

Exterior fireproofing plasters are losing ground to more costly intumescent and endothermic products, simply on technical merit.

At the first lick of a flame, an intumescent coating swells up and expands like beer foam, forming tiny bubbles in a protective barrier that insulates and shields the material below.

For the buried container, only the exposed parts need to be treated with approved fireproofing materials, such as intumescent and or endothermic coatings, or even fireproofing plasters.

By contrast, the intumescent and endothermic coatings are usually epoxy based to begin with, meaning that corrosion of the substrate is no problem whatsoever.

Intumescent firestops are often used, in the event plastic pipes are used for toilet drains, so that the melting plastic pipe is choked off in the event of an accidental fire.

An intumescent is a substance which swells as a result of heat exposure, thus increasing in volume, and decreasing in density. ...

(INTUMESCENCE) A characteristic of certain fire barrier products that, when exposed to heat, expands to fill a void in the penetration caused by the deformation or combustion of the through penetrating item. ...
(Intumescence) A mechanism whereby fire-retardant paints protect the substrates to which they are applied. An intumescent paint puffs up when exposed to high temperatures, forming an insulating, protective layer over the substrate.
(Intumescence) The swelling of a fire- retardant coating when heated, resulting in the formation of low-density film which provides a degree of surface flame-spread resistance.
(intumescence) Hyperplastic symptom characterized by blister-like swelling on the surfaces of plant organs. (20)
