An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
Solvent degreasing is a process used to prepare a part for further operations such as electroplating or painting. Typically it uses petroleum , chlorine , dry ice or alcohol based solvents to dissolve the machining fluids and other contaminants that might be on the part.
Alkaline cleaning agents contain strong bases like sodium hydroxide or potassium hydroxide. Bleach (pH 12) and ammonia (pH 11) are common alkaline cleaning agents. Often, dispersants, to prevent redeposition of dissolved dirt, and chelants, to attack rust, are added to the alkaline agent.
Usually, the cleaning takes place in a workshop. Several common methods include solvent degreasing, vapor degreasing, and the use of an aqueous parts washer. Companies often want the charging, loading and unloading to be integrated into the production line, which is much more demanding as regards size and throughout the ability of the cleaning ...

Here's a selection of useful tips to help you. We gave Gold Diggers a score of 3.5 out of 5 in our review earlier this morning, and while it's true that the game isn't particularly innovative, it ...
Heavy material that settles is referred to as sag, which causes a wide variation in the density of well fluid. This more frequently occurs in high-angle and hot wells. High concentrations of drill solids are detrimental to drilling efficiency because they increase mud weight and viscosity, which in turn increases maintenance costs and increased ...
Reports of human injury are uncommon despite its wide usage in dry cleaning and degreasing. [24] Although limited by its low volatility, tetrachloroethylene has potent anaesthetic effects upon inhalation. [8] [25] The risk depends on whether exposure is over minutes or hours, or over years. [8]
