The process can be automated which makes the process faster and more efficient. There are no consumables with laser technology and the operators do not need to wear operating gear except for a laser goggle to protect their eyes. The ejected particles are collected by a vacuum pump right away and hence there are no danger of contamination of the environment. The laser would generate a plasma which in turn creates a shock wave in the paint and blasts it into pieces and hence a clean removal of paint is performed. Several other case studies also showĪn efficient, healthy and green alternative to sue of paint strippers is using a near IR fiber laser to strip the paint. Later on in the day he experienced severe chest Was working in the basement for 3 hours with a gas furnace located in it and He applied a paint stripper top the furniture and To perform furniture refurbishing as a hobby. Performed on hazardous effects of DCM and one particular example is the case ofĪ 66 year retired old man with no previous history of heart disease who chose Care has to be taken not to use these paint strippers in areas where there is a possibility for a spark such as in locations where furnaces have been installed.Ĭase studies for hazardous effects of Di-Chloro-Methane(DCM): Methylene chloride is non-flammable but it is highly recommended to use this paint stripper either outdoors or if it needs to be used indoors, in a space where there is sufficient air circulation.įlammable type (Acetone, Toluene and methanol)įlammable types of paint strippers contain acetone, Toluene and methanol. Figure 3 shows the possible mechanisms of conversion of Di-Chloro-methane to carboxyl hemoglobin The conversion of carbon monoxide to carboxyl hemoglobin in the blood is quite dangerous for the body and may cause suffocation and heart issues. Also it is known that after chemical reaction with paint, DCM produces carbon monoxide which is quite dangerous for breathing and could cause suffocation. Environmental Protection Agency (EPA) has classified this material as carcinogenic. The inflammable type mostly contains methylene chloride or otherwise known as di-chloro-methane (DCM, CH 2CL 2). Each of these types of paint strippers have some pros and cons which will be described in detail but what is common between the two types is the danger to the health by breathing the toxic vapours they emit and also the fact that they are carcinogenic. Several different types of paint strippers are used for removing paint but they can be mostly classified into two categories, flammable and non-flammable types. The process is quite labour intensive as well and can’t be automated. In addition the high amount of toxic waste that is generated needs to be disposed safely.
