Persoonlijke beschermingsmiddelen moeten niet alleen veilig zijn in het gebruik, maar ze moeten ook een goede bescherming kunnen bieden. Op het gebied van persoonlijke beschermingsmiddelen gelden er dan ook vele richtlijnen en normen. Verschillende modellen worden op deze pagina toegelicht om inzicht te krijgen in:

  • De risico factoren van werkkleding;

    Evaluating personal protective equipment

    In the field of textile testing there are a large number of guidelines and standards that must be met to reliably analyse data and to be able to compare results with the literature values, benchmark experiments in the literature are carefully examined.

    For example: for a bleaching experiment we use internationally recognized standards to indicate degree of whiteness. When evaluating fire protection work wear, responses are that the uniforms do not fit and are too hot during task performance. for a meaningful evaluation we have to consider heat balances and the effect of wearing these uniforms or more general work wear on: Metabolism, Heat Storage, Radiation, Convection (conduction), Evaporation.

    Experimental set up to evaluate risk factors in work wear.

    Daanen (2009) developed an experimental set up to evaluate risk factors in work wear.

    Risk factors include:

  • High temperature,
  • High humidity,
  • No wind,
  • (Solar) Radiation,
  • Insulating clothes,
  • High exercise intensity,
  • Worst case: work in impermeable clothing.

    Factors of strain on the human body in critical working environments

    Daanen also developed a comprehensive model combining several factors of strain on the human body in critical working environments

  • Work, protective equipment, environment,
  • Individual,
  • Physiological strain.
  • This shows that when designing PPE, safety should not be the soul item to adress.
