If your employees are working around dust, fumes, gases or other airborne hazards, you may be wondering whether they need respiratory protective equipment (RPE).
The obvious answer might seem to be: give everyone a mask.
But it isn't quite that simple.
RPE is an important form of personal protective equipment, but it shouldn't be the first solution to a respiratory hazard.
The first question should be: can the exposure be controlled at source?
RPE Shouldn't Be the First Solution
Respiratory protective equipment protects the person wearing it from breathing in hazardous substances.
But it doesn't remove the hazard from the workplace.
Before relying on RPE, employers should look at whether the hazard can be eliminated, whether a safer substance or process can be used, and whether engineering or other controls can reduce the exposure.
Could the process be enclosed? Could ventilation be improved? Could the way the work is carried out be changed?
If the exposure cannot be adequately controlled through other reasonably practicable measures, RPE may then be required.
So, putting on a respirator shouldn't be a substitute for dealing with the source of the problem.
When is respiratory protective equipment required at work? Find out when RPE should be used, why fit testing matters and how OHSS can help.
