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. Guitars made by smaller shops (luthiers) also often use "nitro" as it has an almost mythical status among guitarists. Guitars sometimes shared color codes with current automobiles. Also littles, little ones, little balls. But looking down at all those different colored balls can undoubtedly be a little confusing. You use the cue ball to hit other balls into the pockets of the Pool table. 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.

It remains open until one player legally pockets any called ball other than the 8 after the break. Training courses with set up shots the player can practice on for the various game disciplines. The objective of a billiards game is to score a fixed amount of points, or to score the highest number of points within a set time limit that is agreed upon at the beginning of the game. The object of the game is to reach a certain number of points, typically seven, earned by being the first to run a hoop. It fell out of favor for mass production use for a number of reasons including environmental regulation and the cost of application vs. Durability of finish, complexities of "multiple stage" modern finishes, and other factors including environmental regulation led manufacturers to choose newer technologies. Norman Rockwell often depicted the game, including in his painting Croquet. 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. 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.

The shooter deliberately pockets the opponent's balls while shooting the 8 ball. While this triggering would likely damage or destroy a significant portion of the projector's components, it would contain a fire and prevent far greater damage. Then a second fire hit the Edison Company at another location on December 9, at its film-processing complex in West Orange, New Jersey. Later that same month, many more reels and film cans of negatives and prints also burned at Edison Studios in New York City, in the Bronx; then again, on May 13, a fire at Universal Pictures' Colonial Hall "film factory" in Manhattan consumed another extensive collection. Even after film technology changed, archives of older films remained vulnerable; the 1965 MGM vault fire burned many films that were decades old. It remained in almost exclusive use in all film gauges until the 1980s, when polyester/PET film began to supersede it for intermediate and release printing.

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. Commercial production started in 1891, but the result was flammable and more expensive than cellulose acetate or cuprammonium rayon. PET, like cellulose mononitrate, is less prone to stretching than other available plastics. On the other hand, more intense or bright colors like red and yellow have been known to strain and fatigue the eyes or even give people headaches. Many studies have also shown that certain colors tend to elicit certain moods or states of mind. Projection rooms may also be required to have automatic metal covers for the projection windows, preventing the spread of fire to the auditorium. The projector is additionally modified to accommodate several fire extinguishers with nozzles aimed at the film gate. Also, polyester film is so strong, it will not break under tension and may cause serious damage to expensive camera or projector mechanisms in the event of a film jam, whereas triacetate film breaks easily, reducing the risk of damage.
