Lab Safety: A Comprehensive Guide for O Level Chemistry Practical Students

O Level chemistry comprises three components: Paper 1, Paper 2, and Paper 3. Paper 3 is the practical examination. It has a variable number of questions and has a time duration of 1 hour and 45 minutes. To ace the O Level Chemistry Practical, students must be conscious of the subject content, lab rules, and safety measures.

In this article, we have provided a comprehensive lab safety guide for O Level students.
