For example, exhalation valves on disposable respirators reduce airflow towards spectacles and can greatly reduce lens fogging. Some respirators also have non-breathable sections that further reduce the airflow directed towards spectacles. Another example is the combination of protective ear muffs and protective spectacles. Bulky, rigid spectacle arms are most likely to reduce ear muff performance, but it is impossible to know without testing them together. 3M has developed its Peltor X-Series ear muffs by 3M and SecureFit Eye Protection by 3M in unison to minimise this potential issue. Anyone concerned about the level of hearing protection provided by ear muffs when worn with spectacles should ask the manufacturer for performance data relating to their specific scenario. Similarly, manufacturers of multiple types of PPE, such as 3M, may be able to suggest product alternatives for anyone having particular difficultly finding the right combination. twitter: @surfaceworldmag The last thing to consider is validating your decisions – checking that any equipment changes are having the desired effect. Tight-fitting respirators should be fit checked to ensure they provide protection for the worker. Because of the potential for compatibility issues, it is important that workers wear all their PPE when they are fit checked in this manner. Other validation techniques can be as simple as follow-up surveys, observations and workshop sessions. Whatever compatibility solutions employers choose, PPE must be both adequate and suitable. Adequate simply means the PPE should match the necessary hazards. Selecting suitable PPE requires worker engagement, observing workers using the equipment, and assessing the hazard, environment and workers’ lifestyle needs.
