This testimony is offered in response to a request for information from NIOSH regarding documentation of worker exposure to formaldehyde (50000) and the suggested criteria for safe handling. The documents transmitted with this testimony include the Criteria for a Recommended Standard, Occupational Exposure to Formaldehyde, and Current Intelligence Bulletin No. 34, Formaldehyde: Evidence of Carcinogenicity. NIOSH has no information beyond that found in the previous recommendation and continues to recommend that formaldehyde be considered a potential occupational carcinogen and treated as such. NIOSH believes that OSHA has sufficient documentation to support rulemaking and to promulgate a more protective formaldehyde standard.
