Goodwin's patent was sold to Ansco, which successfully sued Eastman Kodak for infringement of the patent and was awarded $5,000,000 in 1914 to Goodwin Film. During the year 1914-the same year that Goodwin Film was awarded $5,000,000 from Kodak for patent infringement-nitrate film fires incinerated a significant portion of the United States' early cinematic history. Cinema fires caused by the ignition of nitrocellulose film stock commonly occurred as well. The crucial advantage cellulose triacetate had over nitrate was that it was no more of a fire risk than paper (the stock is often referred to as "non-flam": this is true-but it is combustible, just not in as volatile or as dangerous a way as nitrate), while it almost matched the cost and durability of nitrate. If you are installing over an existing table, just make sure to have a pool table cover or other layer over the surface to protect from dust and debris. That fire, a catastrophic one, started inside a film-inspection building and caused over $7,000,000 in property damages ($213,000,000 today).

Yet again, on June 13 in Philadelphia, a fire and a series of explosions ignited inside the 186-square-meter (2,000-square-foot) film vault of the Lubin Manufacturing Company and quickly wiped out virtually all of that studio's pre-1914 catalogue. Some pool tables are constructed so you can reach inside any of the pockets and feel past the edge of the cloth on the playing surface. While some of these features can be defeated with conventional picking tools and are covered here, picking high security locks generally requires specialized tools and techniques (often designed for a specific brand or model of lock) and are beyond our scope here. Finally, for a real challenge, try the Yale "Y1" keyway locks. Today, the Dryden Theatre at the George Eastman Museum is one of a few theaters in the world that is capable of safely projecting nitrate films and regularly screens them to the public. In the meantime, George Eastman had already started production of roll-film using his own process.

Although triacetate does not decompose in as dangerous a way as nitrate does, it is still subject to a process known as deacetylation, often nicknamed "vinegar syndrome" (due to the acetic acid smell of decomposing film) by archivists, which causes the film to shrink, deform, become brittle and eventually unusable. The underlying locking mechanism is still mechanical and may be subject to mechanical bypass. Acetate film manufactured during the era when nitrate films were still in use was marked "Safety" or "Safety Film" along one edge in dark letters. The use of nitrate film and the looming threat of its fiery potential were certainly not issues limited to the realm of motion pictures or to commercial still photography. Nitrate dominated the market for professional-use 35 mm motion picture film from the industry's origins to the early 1950s. While cellulose acetate-based safety film, notably cellulose diacetate and cellulose acetate propionate, was produced in the gauge for small-scale use in niche applications (such as printing advertisements and other short films to enable them to be sent through the mails without the need for fire safety precautions), the early generations of safety film base had two major disadvantages relative to nitrate: it was much more expensive to manufacture, and considerably less durable in repeated projection.

Related fires in other medical facilities prompted the growing disuse of nitrocellulose stock for X-rays by 1933, nearly two decades before its use was discontinued for motion-picture films in favour of cellulose acetate film, more commonly known as "safety film". Decades later, storage at low temperatures was discovered as a means of delaying these reactions indefinitely. Even after film technology changed, archives of older films remained vulnerable; the 1965 MGM vault fire burned many films that were decades old. Salvaging old films is a major problem for film archivists (see film preservation). Many films produced during the early 20th century were lost through this accelerating, self-catalyzed disintegration or through studio warehouse fires, and many others were deliberately destroyed specifically to avoid the fire risk. So let's get again to Mr Thurston and existence within the 18th century! This was used commercially as "celluloid", a highly flammable plastic that until the mid-20th century formed the basis for lacquers and photographic film.
