 may be emitted from CCP. These include adequate ventilation, humidity, and temperature controls; proper housekeeping; minimal hand-to-mouth and hand-to-eye contact; and periodic cleansing of hands.

In addition, NIOSH recommends the following:


 * CCP manufacturers and their suppliers are encouraged to follow best practices, such as the Product Stewardship Code of Management Practices [American Chemistry Council 2000]; they should also consider enhancing their product guidance to reflect that published studies indicate that irritative symptoms appear to increase with increasing exposure to CCP.


 * CCP manufacturers and their suppliers should also consider how human test procedures (e.g., RIPT) can be modified by the use of standardized protocols that include proper controls (e.g., bond paper), tests that mimic high-use situations, and meaningful criteria for scoring and interpreting these tests to assess safety from skin contact (e.g., ASTM D 6355-98) [ASTM 1999]. Current best practices in the field of product testing may not be sensitive enough to identify mild skin irritants.

 * As part of ongoing surveillance, CCP manufacturers and their suppliers may want to evaluate the frequency and severity of irritation in workers using CCP.
