Normal propyl bromide (nPB) has been used for decades as a replacement 1-1-1 Trichloroethane (TCE) and other harmful vapor degreaser solvents. Limited exposure to nPB in a vapor degreaser can lead to acute health concerns like dizziness, paresthesia, respiratory difficulty, mental confusion & more. However, extended exposure to n-propyl bromide can result in more serious long-term neurological damage, cancer, and permanent paresthesia. n-propyl bromide is a powerful liquid degreaser solvent but the potential health ramifications should cause concern for employees and maintenance engineers who are responsible for vapor degreasers. For legacy vapor degreasers it is possible for errant solvent vapors to escape containment and pose inhalation dangers. These TCE or nPB solvent vapors migrate away from the metal parts & the intended vapor zone and extend into the airspace of the workshop. |
