Protecting Workers from Ultraviolet Radiation - icnirp

Protecting Workers from Ultraviolet Radiation
• The initial work task analysis and worst-case exposure assessment including spatial and
temporal factors, such as the time and duration of lunch and work breaks
• Photographs or videos of the workplace and the work carried out if a more detailed work
task analysis is required.
• The aims, e.g. proposals for improving the exposure situation and the safety at work if
necessary
• All other necessary details concerning the workplace, the exposed people, the
engineering and administrative procedures in place and the type of hats and clothing
being worn, available shade and shade structures, etc.
As noted previously, the assessment of UVR exposure for different work conditions is very
difficult. Table 9 provides a set of factors that quantitatively influence the magnitude of skin
exposure in the outdoor environment. These factors are not all strictly independent, although it is
possible to make an indicative assessment if some details of work location, season, duration,
environment and levels of protection are known or can be estimated. Comparable hazard
assessment factors for ocular exposures are given in Table 10. These Tables list factors that can
be used for the hazard assessments.
