Lord Baltimore Press. pp. Vol. 1. Oxford: Pergamon Press. New York: Lyons Press. Projection rooms may also be required to have automatic metal covers for the projection windows, preventing the spread of fire to the auditorium. The use of volatile nitrocellulose film for motion pictures led many cinemas to fireproof their projection rooms with wall coverings made of asbestos. 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. Rather, with the increased use of automated long-play systems in cinemas, the greater strength of polyester has been a significant advantage in lessening the risk of a film performance being interrupted by a film break. The 1997 miniseries features the use of croquet however, Stanley Kubrick's 1980 film adaptation uses a fire axe instead. That tragedy claimed 123 lives during the fire and additional fatalities several days later, when hospitalized victims died due to inhaling excessive amounts of smoke from the burning film, which was laced with toxic gases such as sulfur dioxide and hydrogen cyanide.

In Ireland in 1926, it was blamed for the Dromcolliher cinema tragedy in County Limerick in which 48 people died. Cellulose triacetate superseded nitrate as the film industry's mainstay base very quickly. By the late 1990s, polyester had almost entirely superseded triacetate for the production of intermediate elements and release prints. It fell out of favor for mass production use for a number of reasons including environmental regulation and the cost of application vs. It remained the favorite of hobbyists for both historical reasons and for the ease with which a professional finish can be obtained. This is not common practice for most professional tournaments. So, depending on the rules of the particular game, two common outcomes are practiced after a table scratch. As a result, it’s always best to agree upon common rules before the game starts, to make sure all players are on the same page. The hybrid game eight-ball rotation is a combination of eight-ball and rotation, in which the players must pocket their balls (other than the 8, which remains last) in numerical order.

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". 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. Owing to public safety precautions, London Underground forbade transport of movies on its system until well past the introduction of safety film. Nitrocellulose film base manufactured by Kodak can be identified by the presence of the word "nitrate" in dark letters along one edge; the word only in clear letters on a dark background indicates derivation from a nitrate base original negative or projection print, but the film in hand itself may be a later print or copy negative, made on safety film.

Triacetate remains in use for most camera negative stocks because it can be "invisibly" spliced using solvents during negative assembly, while polyester film is usually spliced using adhesive tape patches, which leave visible marks in the frame area. Today, nitrate film projection is rare and normally highly regulated and requires extensive precautions, including extra health-and-safety training for projectionists. A training film for projectionists included footage of a controlled ignition of a reel of nitrate film, which continued to burn even when fully submerged in water. The extinguishers automatically trigger if a piece of film near the gate starts to burn. 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 film was also used for many years in the field of medicine, where its hazardous nature was most acute, especially in its application to X-ray photography. Due to their flat and hard surface, they maintain a level playing field for a longer time.
