Definition of DOT Class 9: Miscellaneous Hazardous Materials

Class 9 covers materials which are hazardous for transportation but do not otherwise fall into the Class 1 to Class 8 classifications.

Class 9 materials include anesthetic, noxious, or other similar materials which could inhibit the performance of a flight crew member if released. They also include elevated temperature materials, hazardous substances, hazardous waste, and marine pollutants that meet a definition within 49 CFR 171.8 but not a specific Class definition.

Relationship Between Class 9 and OSHA Hazard Classifications

Since Class 9 is strongly defined more by the material's properties being hazardous in transportation, there is minimal overlap with OSHA Hazard Classification.

OSHA has separate Hazards Not Otherwise Classified apart from Physical Hazards and Health Hazards.

While PHMSA Class 9 includes materials which are considered elevated temperature material and marine pollutants, OSHA Hazards Not Otherwise Classified includes materials such as those which produce combustible dusts.

What is Mica Powder? Mica is a group of natural hydrous silicate minerals noted for their lustrous shine, which makes it a popular additive in powder pigments. Mica can be found both in cosmetics and in artists' pigments used in painting, epoxy resin, soapmaking, and other crafts. Mica groups several different naturally occurring hydrous silicate minerals, including the more common biotite and muscovite, as well as lepidolite, margarite, phlogopite, roscoelite, and zimmwaldite. Mica has a CAS Number 12001-26-2. The CAS Number is used to identify mica as an ingredient on safety data sheets (SDS) and other safety documentation. When looking for mica as an ingredient in pigments, colorants, finishes, or other materials, look for the CAS Number within the composition table. Notable Properties of Mica Powder Mica is most noted for its lustrous shine or shimmer due to the shape of the hydrous silicate crystals.

Safety Glasses are on the Left and Safety Goggles are on the Right What is the Difference Between Safety Glasses and Safety Goggles? Safety glasses and safety goggles are both types of eye protection. Choosing which type to wear for a given task is an important part of safety, both in the workplace and when working on home projects or crafts. Safety glasses have a frame, lenses, and side shields. Safety glasses offer protection against impacts but do not offer protection against liquid splashes or fine dust. Safety glasses may be worn over prescription glasses, though this is generally uncomfortable and prone to slippage. It is possible to purchase safety glasses with prescription lenses. Safety goggles have a frame, lens, side shields, and a sealing surface. The sealing surface allows safety goggles to protect against liquid splashes and fine dust from reaching the eyes, as well as from impacts. Safety goggles can be worn over prescription glasses. It is also possible to purchase safe
