Nonmetallic material, or in nontechnical terms a nonmetal, refers to materials which are not metals. Depending upon context it is used in slightly different ways. In everyday life it would be a generic term for those materials such as plastics, wood or ceramics which are not typical metals such as the iron alloys used in bridges.
Even though the end product is a less-toxic alternative to acrylamide for end users, the hazards to workers manufacturing the material should also be considered in an alternatives assessment. A regrettable substitution occurs when a material or process believed to be less hazardous turns out to have an unexpected hazard.
Fire-retardant materials should not be confused with fire-resistant materials. A fire resistant material is one which is designed to resist burning and withstand heat . An example of a fire-resistant material is one which is used in bunker gear worn by firefighters to protect them from the flames of a burning building.
Non-flammable non-toxic gases – Gases which: are asphyxiant – gases which dilute or replace the oxygen normally in the atmosphere; or; are oxidizing – gases which may, generally by providing oxygen, cause or contribute to the combustion of other material more than air does; or; do not come under the other divisions. Alternative sign ...
Chemical free (also chemical-free) is a term used in marketing to imply that a product is safe, healthy or environmentally friendly because it only contains natural ingredients. [1]
The goal of the substitution process is to improve occupational health and safety and minimize harmful environmental impacts. [1] The process can be time-consuming; assessments of dangers, costs, and practicality may be necessary. Substituting hazardous chemicals follows the principles of green chemistry and can result in clean technology. [2]
Alternative natural materials are natural materials like rock or adobe that are not as commonly used as materials such as wood or iron. Alternative natural materials have many practical uses in areas such as sustainable architecture and engineering. The main purpose of using such materials is to minimize the negative effects that built ...
Hazardous materials are often subject to chemical regulations. Hazmat teams are personnel specially trained to handle dangerous goods, which include materials that are radioactive, flammable, explosive, corrosive, oxidizing, asphyxiating, biohazardous, toxic, poisonous, pathogenic, or allergenic. Also included are physical conditions such as ...
