The negatives of web-based MSDS information is the variety and unfamiliarity of the different sites. Unless you have someone who accesses these sites occasionally, finding exactly the right MSDS may be problematic and time consuming. In a medical emergency, the manufacture of the chemical must make information available to the treating physician. Most MSDS providers can fax the most current MSDSs to you in a short amount of time. The rate limiting step in this option is getting the phone number of the provider.
Problems can occur if the call is after normal business hours for the manufacturer.
Finding the phone number of the chemical provider becomes the rate limiting step sometimes. We suggest that you consider your procedures carefully and determine the best way to get the information you need quickly and reliably. We don't mean to infer that we are not willing to provide MSDSs. We only mean to point out that we are not set up to provide the information immediately at all times. Being aware of these alternate resources, and their limitations, may help you get the information you need when you need it.
