Interpretation:
Correct Symbol for the safety rule being described is to be designated.
Concept introduction:
A significant part of chemistry is the research and analysis, where one in laboratory conducts experiment to test hypothesis by observation and analysis of obtained data obtained by him and finally drawing conclusion.
But working in laboratories requires attention to certain lab rules or protocols known as safety rules. Safety rules are important for one’s own safety and other working along. Some of the rules are as follows:
- Never work in laboratory alone, without permit of teachers.
- Study lab safety measure beforehand attending the lab.
- Wear safety goggles and apron in lab.

Answer to Problem 16STP
Image in E depicts chemicals with strong fumes must be used in fully ventilated rooms.
Explanation of Solution
Safety rules in labs are depicted generally by safety symbols. These safety symbols are meaningful images that warn the lab user of the hazards beforehand or correct practices to be carried out in laboratory.
The safety symbol represented in A depicts that material being used is flammable when exposed to water or air. So care must be taken.
The safety symbol represented in B depicts that hand gloves must be worn in labs before using chemicals that can cause skin irritation or burn on coming in contact.
The safety symbol represented in C depicts that safety goggles must be worn to protect eyes from harmful fumes or any accident while in lab.
The safety symbol represented in D depicts that apron must be worn to protect clothes and oneself from harmful chemicals in lab.
The safety symbol represented in E depicts that chemical being used emit very strong fumes which can be injurious to health. So, proper measure must be taken.
So image in E depicts chemicals with strong fumes must be used in fully ventilated rooms.
Image in E depicts chemicals with strong fumes must be used in fully ventilated rooms.
