Respirators may be necessary when engineering and administrative controls do not adequately prevent exposures . The decision to use respiratory protection should be based on professional judgment that takes into account toxicity information , exposure measurement data , and frequency and likelihood of the worker ' s exposure - ensure users are not subject to high thermal loads which may result in heat stress or distress due to personal protective equipment ( powered , positive flow , full face apparatus may be an option ). Published occupational exposure limits , where they exist , will assist in determining the adequacy of the selected respiratory protection . These may be government mandated or vendor recommended . Certified respirators will be useful for protecting workers from inhalation of particulates when properly selected and fit tested as part of a complete respiratory protection program . Use approved positive flow mask if significant quantities of dust becomes airborne . Try to avoid creating dust conditions .
