	One big danger with solvents is that '''they can cause trouble before you realize what’s happening'''. Depending on the type and concentration of the solvent, exposure effects can range from mild respiratory irritation to severe damage to body organs and systems. In extreme cases, overexposure to solvent vapors can cause respiratory failure and death.		One big danger with solvents is that '''they can cause trouble before you realize what’s happening'''.
