Returned lid was photographed and subject to ftir analysis.Ftir indicated a high degree of oxidation consistent with uv embrittlement.Canister was a component of a portable pump, exposed to lighting for an extended period.Product was past its expiration date.Immediate actions: requested return of lid so that lab analysis can be performed.Investigation results/response to customer: complaint received from (b)(6) states the incident occurred on (b)(6) 2013.The product has an expiration date of 06/2013.Preliminary probable cause would appear to be embrittlement of the ageing cover due to excessive uv exposure.In our experience, most portable pump manufacturers include a warning to replace suction canisters on a routine annual basis as part of the facility's pm process to specifically address this type of failure.Once the part is returned, we can perform analysis on the plastic and confirm (possibly) this is the cause.Conclusion: returned fractured cover was received on 1/21/2014 and was forwarded to the lab for ftir analysis.On (b)(4) 2014 the lab reported back with results indicative of a high degree of oxidation typical of high density polyethylene exposed to uv for an extended period.This supports the initial probable cause.Lab analysis is attached to this report.
