Hazard Register

Revised: 23 June 2009

All chemicals and products with hazardous properties, which are held in more than 100 mL containers require an MSDS (material safety data sheet). The MSDS for each product shall be stored in the MSDS and Calibration Certificate folder in the laboratory.

Should products not be supplied with an MSDS, most can be obtained using free MSDS services on the internet. The site should also be used to check for the most recent information regarding first aid and emergency action.

Other suppliers also have an MSDS service available: Merck chemicals, and Hach. The “Favorites” menu of Explorer has MSDS links and Manufacturer Links in the section on Chemical Safety.
