Guidelines of occupational exposure

The search strategy revealed 1287 studies, 1260 excluded. Finally 27 studies were included. Nurses' compliance to the guidelines of occupational exposure to pathogenic microorganisms is described as unsatisfactory, and an emergency situation has been shown to be the major obstacle to follow the guidelines. It is necessary to understand the factors which contribute to nurse’s noncompliance. The results show that there is a need to propose measures that will positively affect the nurses’ performance.

The previous WHO guidelines were established for 15 minutes to protect against short-term peak exposures that might occur from, for example, an un- vented stove; for 1 hour to protect against excess exposure from, for example, faulty appliances; and for 8 hours (which is relevant to occupational exposures and has been used as an averaging time for ambient exposures). We do not rec- ommend changing the existing guidelines. However, chronic carbon monoxide exposure appears different from acute exposure in several important respects.

The guidelines are targeted at public health professionals involved in prevent- ing health risks of environmental exposures as well as specialists and authorities involved in the design and use of buildings, indoor materials and products. The guidelines are based on the accumulated scientific knowledge available at the time of their development. They have the character of recommendations. Nev- ertheless, countries may wish to use the guidelines as a scientific basis for legally enforceable standards.

Very limited evidence was available to inform the following recommendations on screening. No prospective studies have evaluated the impact of screening on survival, quality of life, or morbidity from treatment for skin cancer nor are there data on the adverse effects of screening for skin cancer. As experts in the treatment and epidemiology of skin cancer, the guideline panel members were aware that some individuals are at increased risk for skin cancer because of personal characteristics or history.

Although major trends may emerge and show numerous toxic effects related to certain NP, it can be seen that each product, and even each synthesized NP batch, can have its own toxicity. Any process or surface modification can have an impact on the toxicity of the resulting product. Given this context, the authors of this report consider that the IRSST should favour the introduction of strict prevention procedures, which remain the only way to prevent the development of occupational diseases.
