All chemicals used or stored in a laboratory
must be listed and must have a current MSDS.
The list and the MSDSs must be available to
those using the lab.
    While Working in the Lab:
n   Know the emergency escape
    route and alternate
n   Know the emergency spill
    procedure
n   Know the location of the first
    aid kit, eye wash
    station/shower, spill kits,

    exposure to hazardous materials
4   Allow only fully covered shoes
    with slip resistance
4   Restrain long hair and loose
    clothing
4   Wear appropriate eye
    protection, to protect against
    the risk of flying dust particles,
