Ordinary dry chemical extinguishers are used for Class B and C fires only. They often contain sodium bicarbonate (baking soda), which comes out as a white powder. Inhalation of monoammonium phosphate and sodium bicarbonate can cause mild irritation to the nose, throat, and lungs and results in symptoms like shortness of breath and coughing.

Chemical Chemical Hazard and Compatibility Information Chlorine HAZARDS & STORAGE: Severe health hazard. Corrosive gas that may be shipped as a liquid. Strong oxidizer. Most combustibles will burn in chlorine as they do in oxygen. INCOMPATIBILITIES: N-aryl sulfinamides, Acetaldehyde, Acetylides (metal), Air, Alcohols, Alkylisothiourea
The Sonogashira coupling reaction catalyzed by ultrafine nickel(0) powder has been developed; terminal alkynes couple with aryl, alkenyl iodide and aryl bromide in the presence of cuprous iodide, triphenylphosphine, potassium hydroxide and ultrafine particle nickel(0) to provide the corresponding cross-coupling products with high yields.
By using this single‐crystal structure as a starting model for subsequent Rietveld refinement of X‐ray powder diffraction data, the structure of the powder synthesized from CuI and tBuC CH was found to have the same structure as 1.

The word "powder" refers to a chemical or mixture that is solid in physical state. In compounding, "powder" refers to a dosage formulation that is solid in physical state. But the formulation may be composed of only the active drug or may be a mixture of the active drug and other ingredients.
A new and efficient copper-catalyzed C3 aryl- and heteroarylselenation of indoles employing selenium powder has been developed. The advantages of this chemistry involve the use of cheap selenating reagents, tolerance of a variety of functional groups, and practicality. In addition, this protocol has been further elaborated in an intramolecular phenylselenation of a (hetero) aryl C–H bond to ...
