Glass container safety

A liquid-based oral drug product typically needs to be protected from solvent loss, microbial contamination, and sometimes exposure to light or reactive gases (e.g., oxygen). For glass components, data showing that a component meets the requirements of USP Containers Glass containers are accepted as sufficient evidence of safety and compatibility. For LDPE components, data from USP container tests are typically considered sufficient evidence of compatibility. 

For digestion of silica-based materials only. Cannot be used with glass containers (use plasticware). In addition to laboratory coat and safety glasses, extra safety precautions are needed, e.g. gloves. In case of spillages, calcium gluconate gel is required for treatment of skin contact sites and should be available during use evacuate to hospital immediately if skin is exposed to liquid HF... 

Place ten to fifteen aspirin, plain or buffered, into a glass container. With your safety glasses on, pour in a half cup (120 milliliters) of rubbing alcohol 70 percent isopropyl alcohol works just fine. This amount should be enough to cover the tablets with some to spare. It doesn t take much solvent to extract the acetylsalicylic acid from the tablets. 

If you let your crystals dry overnight, then find your safety glasses again and put them on. Take about a quarter of either the wet or dry acetylsalicylic acid crystals and place them into a glass container that can be used for warming. The dried crystals are very fluffy and should be handled carefully so they do not scatter. Take the bottle of aquarium pH-lowering solution recommended for purchase in the Shopping List and Solutions, and add it dropwise until the entire sample of acetylsalicylic acid is com-... 

Inhalation containers are made of glass, plastic, or metal or a combination of these materials. Glass containers are precisely engineered to provide the maximum pressure safety and impact resistance. Plastics may be used to coat glass containers for improved safety characteristics, or to coat metal containers to improve corrosion resistance and enhance the stability of the formulation. Metals used as containers include stainless steel, aluminum, and tin-plate steel. It is also important that containers should be tested to ensure that extractables or leachables and particulates on the internal surfaces of containers are controlled.

Automobile safety glass contains a sheet of polyvinyl polymer layered between two sheets of glass to prevent the formation of sharp fragments. 

Huorosulfuric acid, HSO3F, is a mobile colorless liquid that fumes in moist air and has a sharp odor. It may be regarded as a mixed anhydride of sulfuric and hydrofluoric acid. It has been known since 1892 and is prepared commercially from SO3 and HF in a stream of HSO3F. It is readily purified by disfillation, although the last traces of SO3 are difficult to remove. When water is excluded, it may be handled and stored in glass containers, but for safety reasons the container should always be cooled before opening because gas pressure may have developed from hydrolysis. 

You will also note that the flammable hazard classification of a chemical determines the allowable containersize for a chemical. Thus, Class lA or HC 1 are only allowed up to 0.5 L in size for a glass container (most laboratories use glass). There is also a limit as to the amount of flammables allowed outside a flammable storage cabinet at any one time. This is very important for your safety, so when you are finished using a flammable you should promptly return it to the flammables cabinet. This reduces your risk in case there is a Are. 

The major use of PVB resin is for the manufacture of sheet used as an interlayer in laminated safety glass for automotive and architectural applications. PVB for laminated safety glass contains typically only 1-3 wt% of residual vinyl acetate units and 18-23 wt% vinyl alcohol imits (49). The remaining hydroxyl... 

Safety Cans. Where practical, safety cans should be used for the dispensing of all flammable and combustible liquids handled in containers. Safety cans should be filled in dispensing rooms and transported to point of use. Safety cans are available in plastic stainless steel and even glass lined stainless steel where high levels of cleanliness are required. 

Flammable liquids. Cover flammable liquid regulations, including safe handling procedures, volume limits, glass container limits, use of safety cans, safety cabinets, and storage areas. 

The conversion of a diazo ketone to an acid amide may be accomplished by treating a warm solution in dioxan with 10-28 per cent, aqueous ammonia solution containing a small amount of silver nitrate solution, after which the mixture is heated at 60°-70° for some time. Precautions should be taken (by use of a. safety glass shield) when heating mixtures containing ammoniacal silver nitrate. 

Health and Safety Factors. Unlike fluoroacetic acid, trifluoroacetic acid presents no unusual toxicity problems. However, owing to its strong acidity, its vapors can be irritating to tissue, and the Hquid acid can cause deep bums if allowed to contact the skin. The acid can be safely stored in containers made of glass or common corrosion-resistant alloys and metals such as stainless steel or alurninum.
