How to Test for Chemicals on Surfaces and Decontaminate Watch as SKC demonstrates how to check surfaces for MOCA. Surface SWYPE indicators are suitable for the OSHA PPE Standard, do not require instruments and analysis, and are available for a variety of chemicals with ACGIH skin notation. Surface SWYPEs play an important role in dermal exposure reduction programs by identifying at-risk surfaces with which workers can come into contact.

Chemical contamination on workplace surfaces can result in significant skin exposure. Identification of areas and tasks for risk of dermal exposure is a critical element in a hazard assessment as required by OSHA’s PPE standard. SWYPEs are a simple and sensitive technique to identify contaminated work sites where protective gloves and clothing must be worn. The use of colorimetric SWYPE systems compliment the use of urine testing in a worker education and training program for controlling employee exposure.

A common sense approach is the key to the successful use of the SWYPE detection systems for reducing workplace exposures. The first step is to observe employee work practices. Tools, machinery controls, safety glasses or pencils that are handled with contaminated gloves and may later be touched by bare skin, represent potential exposures. Procedures for the handing of drums should be checked to ensure that drum surfaces do not become contaminated.

Pump seals and hose connectors can be checked for leaks with Surface SWYPEs . Surface SWYPEs can also be used to determine that urethane parts are completely cured before being handled with bare hands. Skin contact with uncured materials or surfaces in contact with uncured materials may result in worker exposures.

Gloves should be worn when using the Surface SWYPE detectors. First, lightly spray the area to be tested with Developing Solution. Wait approximately 30 seconds and then wipe with a Surface SWYPE pad. Allow 2 – 3 minutes for the color change reaction to occur. Do not reuse the Surface SWYPE after activation. The sensitivity of the Surface SWYPE is 3-5 µg for aromatic amines and isocyanates.

Surface SWYPEs are available for: 

  • Aromatic amines
  • Aromatic isocyanates
  • Aliphatic isocyanates
  • Aliphatic Amines
  • Acid/Base
  • Phenols

Colorimetric SWYPE pads are useful tools for identifying unpolymerized aliphatic isocyanates on a variety of surfaces. This technique has been used in autobody shops to determine the presence of hexamethylene diisocyanate and other aliphatic isocyanates that are important constituents of many automotive coatings. SWYPEs have the advantage of being relatively inexpensive, rapid, and portable. The color change elicited by aliphatic isocyanates (from yellow to red) provides a visual indication of the extent of surface contamination.
