Why must we all know Safety?
•  This isn’t a Manufacturing class. Why do I
need to know Safety?
–  Because as future Architects, Engineers,
Designers, Chefs, etc., YOU need to know how
to stay safe on the job site.
–  You need to know your rights and
responsibilities as Employees and/or
Employer.

working with that substance in a safe manner, and includes
information such as physical data (melting point, boiling point, flash
point, etc.), toxicity, health effects, first aid, reactivity, storage,
disposal, protective equipment, and spill-handling procedures. MSDS
formats can vary from source to source within a country depending on
national requirements.

100% Rule
•  Why do I have to pass the 50 questions
test with 100%?

every finger, toe, etc., safe. 90% means
it’s okay to lose 1 finger, 95% = part of a
finger, etc….
