true
false
flammable materials, like alcohol, should never be dispensed or used near * 2 points
an open door.
an open flame.
another student.
a sink
other.

Explanation:

• For the first question: In a laboratory, chemicals and equipment are meant for laboratory - specific use. Removing them can lead to safety hazards (if chemicals are misused outside the lab) and disrupt the proper functioning of the lab (as equipment is calibrated for lab use). So, the statement "Never remove chemicals or other equipment from the laboratory" is a standard safety rule and is True.
• For the second question: Flammable materials like alcohol can easily catch fire. An open flame provides a source of ignition. Dispensing or using flammable materials near an open flame is extremely dangerous as it can cause a fire or explosion. Open doors, other students (if they are following safety rules), and sinks (unless there is an open flame - related issue at the sink) do not pose the same level of ignition risk as an open flame.

Answer:

1. True
2. an open flame
