11 Medical SurveillanceHealth Surveillance Essential for Effective Occupational Safety and Health ProgramNo Clear Approach to Medical Surveillance for NanoworkersNIOSH“… insufficient scientific and medical evidence now exist to recommend the specific medical screening of workers potentially exposed to engineered nanoparticles. However, NIOSH did recommend that hazard surveillance be conducted as the basis for implementing control measures.
12 Medical Surveillance ISO/TR 12885:2008(E) It is recommended that a basic worker health monitoring program is established.72 Such a program should include at a minimum:1. identifying staff (nanoparticles workers) exposed to engineered nanoparticles of unknown healtheffects;2. conducting workplace characterization and worker exposure assessments;3. providing nanoparticles workers with “baseline” medical evaluations and including them in anonspecific routine health monitoring program.It is recommended to ensure that engineered nanoparticle workers are offered periodic medical evaluationsthat might include routine tests such as pulmonary, renal, liver, and hematopoietic function testing.
13 Medical Surveillance ASTM E 2535 – 07 Medical Surveillance—For guidance on medical surveillance of UNP workers consult the NIOSH Nanotechnology homepage.Whether a medical surveillance program is warranted is a management decision to be made in consideration of a number of factors including; whether there is good reason to believe that adverse health effects may occur as a result of the contemplated exposure; the invasiveness of the surveillance procedures, the benefits, risks and costs of the surveillance method; and the utility of the information reasonably expected to be generated by the surveillance program.Any medical surveillance program should be developed and implemented only with medical, industrial hygiene and legal professional consultation, and under the direction of a physician experienced in medical surveillance programs with a high level understanding of the available information concerning the UNP and potential exposure circumstances.
