Experimental study on the decontamination of partial contaminated skin

The procedure and method of chemical accident decon-tamination were introduced.The decontamination agent type and the principle for choice were reviewed.The experiments were carried out by using benzene and toluene contaminated skin directly,which are decontaminated by spraying water,oil sorbent granule,liquid sorbent granule and active carbon.At the same time the concentration of the residual of contaminated material on the skin was detected by using AreaRAE Rapid Deployment Kit during the decontamination course.Then the decontamination effects of decontamination agents for various kinds of chemicals were measured,on this basis,the decontamination agent was optimized,as well as the amount of decontamination agents and decontamination time.The experimental result indicated that the contaminated of benzene and toluene on the skin can be cleared up only if the decontamination time is long enough.Moreover,the contaminated material on skin can be removed by solid adsorbent such as oil sorbent granule,liquid sorbent granule and active carbon.As far as the decontamination effect,active carbon is the best for benzene,followed by liquid sorbent granule and oil sorbent granule;however,oil sorbent granule is best for toluene,followed by liquid sorbent granule and active carbon.
