Precautionary statements form part of the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). [1] They are intended to form a set of standardized phrases giving advice about the correct handling of chemical substances and mixtures, which can be translated into different languages.
Non-reusable paint can be made into a product used in cement manufacturing, thereby recycling virtually 100% of the original paint. Recycling one gallon of paint could save 13 gallons of water, 1 quart of oil, and 250,000 gallons of water pollution, 13.74 pounds of CO 2, save enough energy to power the average home for 3 hours.

Wood affected by woodworm. Signs of woodworm usually consist of holes in the wooden item, with live infestations showing powder (faeces), known as frass, around the holes.. The size of the holes varies, but they are typically 1 to 1.5 millimetres (5 ⁄ 128 to 1 ⁄ 16 in) in diameter for the most common household species, although they can be much larger in the case of the house longhorn beet
Bleaching of wood pulp is the chemical processing of wood pulp to lighten its color and whiten the pulp. The primary product of wood pulp is paper, for which whiteness (similar to, but distinct from brightness) is an important characteristic. [1]
Chlorine releasing solutions, such as liquid bleach and solutions of bleaching powder, can burn the skin and cause eye damage, [2] especially when used in concentrated forms. As recognized by the NFPA, however, only solutions containing more than 40% sodium hypochlorite by weight are considered hazardous oxidizers.
Bonsai enthusiasts use undiluted lime sulfur to bleach, sterilize, and preserve deadwood on bonsai trees while giving an aged look. [5] Rather than spraying the entire tree, as with the pesticidal usage, lime sulfur is painted directly onto the exposed deadwood, and is often colored with a small amount of dark paint to make it look more natural.
The diameter of the powder used is relative to the density (g/m 2) of the stock (paper or board) being printed. For 150 g/m 2 paper the ideal anti-set-off spray powder would be 15 μm in diameter, for 200 g/m 2 20 μm, through to 70 μm for heavy board (700 g/m 2). Most manufactures of spray powder offer both coated and uncoated powders.
It is commonly available in powder or granular form and has many industrial and household uses, including as a pesticide, as a metal soldering flux, as a component of glass, enamel, and pottery glazes, for tanning of skins and hides, for artificial aging of wood, as a preservative against wood fungus, and as a pharmaceutic alkalizer.
