Reference excerpt

Sabrina's Law, 2005 (official long title: An Act to Protect Anaphylactic Pupils) is a law in Ontario, Canada, which requires Ontario school boards to establish and maintain policies to protect anaphylactic students from common causes of anaphylactic reactions.

Background The bill's common title is named after Sabrina Shannon, a 13 year old student from Pembroke, Ontario, who died in September 2003 after suffering an anaphylactic reaction at school. Her death and its publicity would contribute to the public support for and later passing of Sabrina's Law.

Legislative history The bill was first introduced during the first session of the 38th Legislative Assembly of Ontario, in November 2003 by then MPP Dave Levac. After its initial introduction it was amended by a standing committee and carried unanimously by the House in May 2005. It was then granted royal assent in June 2005 and came into effect on January 1, 2006.

Provisions The law does not require the banning of any foods, but it does require that every school board establish and maintain an anaphylactic policy to protect students with severe allergies by limiting their risk of exposure to allergens. As a result many schools have elected to ban certain foods outright. The law also requires that schools implement communication plans for providing educational resources about life-threatening allergies to parents and students. School principals are expected to create and maintain individual files for each anaphylactic student in their school. The law also requires that schools train staff to recognize anaphylactic shock and provide first aid.

Worked examples

Example 1 — a first encounter with Sabrina's Law

Start with the simplest possible case. Write down what Sabrina's Law claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Sabrina's Law before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Sabrina's Law ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Sabrina's Law

In research: Sabrina's Law appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Sabrina's Law in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Sabrina's Law is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2005 in Canadian law, 2005 in education, 2006 in Canadian law, so understanding it makes those chapters shorter.
In everyday life: Look for Sabrina's Law outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
