A solution of 35 to 40 per cent of water in formaldehyde or methanol is called formalin. Formaldehyde”s formula is HCHO. The initial material of formalin is methanol which is an alcohol with boiling point of 65 C which will be evaporated quickly and will produce an explosive gas after being combined with oxygen. We should use sparkle equipment, firefighting equipment, gas leaking sensors, different storage equipped with chiller, Nitrogen gas injection part and etc. in order to prevent risks in transportation and storage of Methanol.
1. Used to eliminate infectious agents.
2. Formalin is a wonderful disinfectant particularly on solid surfaces like concrete, wood and PVC.
3. Used In our country formalin is widely used in laboratories as preservative.
4. Used In animal museum, specimen are preserved by using formalin.
Formaldehyde is a natural substance produced by every living organism. It is naturally present in a wide variety of fruits, vegetables, meats, fish, coffee and alcoholic beverages. Formaldehyde is also produced in the human body as a part of normal functions to build the basic materials needed for important life processes.
Studies show that formaldehyde does not accumulate in people or animals because it is quickly broken down by the body’s natural metabolic processes. In the environment, formaldehyde is quickly broken down in the air by moisture and sunlight, or by bacteria in soil or water. Uses of formaldehyde are effectively regulated, and government oversight has been extensive.
- The U.S. Food and Drug Administration (FDA) has reviewed the safety of formaldehyde and approved its use as an indirect food additive in a number of materials having contact with food. FDA also has indicated that formaldehyde can be used in nail hardener products.
- The U.S. Department of Labor’s Occupational Health and Safety Administration (OSHA) has standards for workplace exposures to formaldehyde that provide comprehensive protection for employees through the implementation of good industrial hygiene practices.
- The U.S. Department of Housing and Urban Development (HUD) has long had standards in place that limit formaldehyde emissions from wood products used in manufactured housing.
- Three agencies – the U.S. Environmental Protection Agency (EPA), Consumer Product Safety Commission (CPSC), and HUD – have extensively evaluated and controlled indoor air exposure to formaldehyde. Industry voluntarily adopted product emission standards and developed low-emitting formaldehyde-based resins in the 1980s, and indoor formaldehyde emissions have declined significantly since then. CPSC determined that independent CPSC action was unnecessary, given the voluntary actions and low levels of formaldehyde. The state of California established a performance-based regulatory standard in 2007. And in 2010, Congress, at industry’s urging, enacted legislation mandating a national emission standard for composite wood products.
