The instructions for use of filters and respiratory equipment, as well as the safety standards
and regulations issued by the competent authority, must be strictly followed. Respiratory
protective devices must be used by personnel in good health and trained in the use of this
kind of equipment. Users must be beardless and without sideboards or moustaches as these
interfere with the facepiece seal, thus impeding adequate seal tightness on the face. The
users of SFERA masks must ensure that the highest concentrations of contaminants in the
atmosphere are not exceeded. The permissible exposure limits are indicated in the manual
containing the instructions for use of filters and self-contained breathing apparatuses used
with the mask. In case of contact with lubricants and oil by-products, solvents, oxidizing
agents, acetates, hydrogen peroxide, acids and strong bases, wash and clean the mask
afterwards as soon as possible in accordance with paragraph 7.2.
