While paper can be made of wood fibers alone, little is actually made without some chemical addition or modification. These chemical additives are used to either assist in papermaking or to give the paper certain desirable end-use qualities. These chemicals can be added at virtually any step in papermaking. Some of the additives are used to influence the entire sheet properties. These chemicals are added to the pulp slurry prior to sheet formation (internal addition). When the surface properties of the sheet also need to be altered, additives are used on the sheet after some period of formation or drying (external addition). A number of these chemicals serve commonly as both internal or external additions. 

The design and construction of new structures must comply with the IBC, and any alterations, additions, changes in use, or changes in structures required by the IFC, which are within the scope of the IBC, must be made in accordance with the IBC. 

Misuse of a product by the consumer, such as using a product inverted, results in the discharge of the vapor phase instead of the liquid phase. Most of the propellant is contained in the vapor phase and therefore some of the propellant will be lost and the spray characteristics will be altered. Additionally, the sprays produced using compressed gases are very wet. However, recent developments in valve technology have reduced the risk of misuse by making available valves which will spray only the product (not propellant) regardless of the position of the container. Additionally, barrier systems will also prevent loss of propellant. 

When, for example, proteins are to be labelled with 125-iodine, enzymes or conventional fluorescent labels, the labelling procedures are all rather laborious. Due to the harsh labelling conditions, the proteins may denature when labelling with iodine or an enzyme. As a result of this, and because of the nature of these labels, the immunoreactivity may become lost or altered. Additionally, the iodine label itself is unstable with a short half-life and the radiation energy further destroys the protein with time. Enzyme labels, on the other hand, may lose their activity during the conjugation. Due to the large size of the enzyme label the protein can be labelled to only a very limited extent and the enzyme may be inhibited by several substances.
