Fumes from some nPB-based cleaning fluids can be hazardous if there is significant over-exposure to the fumes. Monitoring the fumes is an important part of a company’s worker safety program. The hazards associated with n-propyl bromide vary by the extent of the exposure. Short-term over-exposure can lead to skin and eye irritation, dizziness or headaches. Long-term tests show effects on fertility in laboratory animals.
First, let’s remind everybody that proper storage, usage and handling procedures, including drum pumps and personal protective equipment, should be used to avoid short-term overexposures especially when there is the potential for splashing or skin contact. Suitable eye protection should be worn to protect against eye contact.
All nPB users should also conduct a simple workplace exposure test using air-monitoring badges to assure worker safety. The use of the badges and the collection of this data memorializes worker exposure levels and to some degree immunizes a company’s against liability in the event of a spurious health claim.
Badges also are available for the HFC and HFE solvents as well, but their toxicity ratings are much higher (safer) than nPB cleaners so these badges are rarely used.
Exposures badges are an easy way for the employee to go about their daily routine while wearing the badge to determine the exposure to a chemical. After wearing the badge for 8 hours, the badge is sent to an independent lab to determine exposure levels.
