STSESNC2P – Grade 10 Applied Chemistry
Chemicals in the Workplace
C1. Analyse how chemical reactions are employed in
common products and processes, and assess the safety
and environmental hazards associated with them
C1.1 Analyse, on the basis of research, the function of chemical reactions in the production of selected products and/or in processes commonly encountered at
home or in the workplace and communicate their findings
C1.2 Identify practical applications of chemical reactions in a particular
professions and assess the associated hazards, including hazards associated
with the handling and disposal of chemicals
C2.7 Investigate applications of acid-base reactions in common products and
processes
How much chemical is produced worldwide
each year?
According to the International Labour Organization
400 million tonnes!
That’s 4000 of these babies…
Where do they come from and what are they used for?
Agricultural chemicals, Food additives, Pharmaceuticals, Fuels for power production, Chemical consumer products, Etc…
For the majority of chemicals used in the workplace,
little or nothing is known about their possible immediate or long-term health effects.
In some countries, workers are required to work — with little or no protection — with chemicals that are known to be hazardous to human health.
In many countries, chemicals are literally dumped into the environment, often with
serious human and environmental consequences.
Nearly all workers today are exposed to some sort of chemical hazard.
Chemical hazards are the most serious health hazard for workers today.

CAREER FAIRSNC2P
CHEMICALS IN THE
WORKPLACE
STSE CUMULATIVE PROJECT
The Young Worker Awareness Program (YWAP) has decided to run a career fair for grade 9 students educating them about the chemicals used in the workplace.
They are currently hiring people to investigate different careers and to assess the hazards associated with
them, and the hazards associated with the handling and disposing of
chemicals. YWAP is interested in hiring YOU
because of your knowledge in chemistry.
