Safety Orientation

Safety features and equipment are installed in classrooms to protect your health and safety. These can include:

Fire Exits - Labelled by standard emergency exit signage

REPORT to your teacher any exit light that is not lit. Your teacher will then notify maintenance.

Teaching Tips

Safety rules can be complex, but a few simple classroom rules, reinforced EACH time students are preparing to use chemicals in the classroom instill an important skill - stopping to assess hazards BEFORE starting work.

Here are a few examples that can be used at the start of a lab:

do
HAVE students verify that safety equipment is in place and in good condition, and that access to the equipment is not blocked.

Suggestion : Have the students do a routine check to ensure there is a clear path to the eyewash station each time chemicals are used in the room. Portable eyewash rinse "bottles" need regular maintenance to ensure they are clean, fresh and ready for use.

  • READ the labels of the chemical(s) that you will be using that day.
  • REVIEW the MSDS before using the chemical(s).
  • USE or wear PPE required for safe use of the chemical(s), as recommended in the MSDS.
  • DISPOSE of the chemical(s) safely as recommended in the MSDS at the end of the lab.
