Air-line respirators are required when solvent levels are higher than the 10 times the PEL of the solvent.
Cartridges for solvents will absorb only so much solvent until breakthrough occurs.
Training is required for any employee wearing respirators.
Respirators are the last choice for protection of employees from solvents, only after other possible methods are found not feasible.
Exhaust ventilation is essential when solvents are used in confined spaces even in moderate amounts.
General ventilation may be as simple as opening a door/window or installing a wall or roof fan to bring in fresh air.
Ways to reduce solvent vapor exposure:
Because most solvents send vapors into the air, inhalation is the most common route of exposure.
Solvents can have a direct effect on the skin and be absorbed through the skin.
Most solvents will burn – except those with chlorine in their chemical makeup (like methylene chloride, or perchloroethylene).
Solvents are liquid chemicals that are used to dissolve oils, greases and paints, or are ingredients in paints, glues, epoxy resins, mastics, inks and pesticides.
