Weekly Lab Checks Eye wash (purge)- Is it clean? Fire extinguisher- Has it been
discharged and, has it been inspected within a year?
Fume Hood – Is the exhaust fan working?
Tubing, pressurized connections – Are they damaged, deteriorated?
Glassware – if it is chipped, throw it out.
Chemical storage – Are chemicals stored in their proper location?
