It has been recognized for some time that the dermal route of exposure to contaminants presents a significant health risk, but there are few regulatory requirements on how this route of exposure can be monitored or reduced. However, due diligence in creating a safe working environment compels the industrial hygienist or safety officer to insure a that surface contamination and dermal exposure to chemicals is kept to minimum.
OSHA states that a complete worksite analysis requires the assessment of surface contamination since workers may be exposed to these contaminants directly through dermal and ingestive routes (e.g., isocyanates, pesticides), and indirectly through inhalation of contaminants that become re-entrained in the air (e.g., asbestos, lead).
This talk will focus on direct reading colorimetric methods of monitoring workplace contaminant deposition on surfaces and skin.
