Working in a chemistry lab can always be fun, without laboratories scientist is a man with no arms. However working in a lab is not so easy, it comes with its own set of laws for precautionary actions which if not followed may lead to a disaster! Whether you are a lab technician, a student, or a scientist, it’s crucial to know basic chemistry lab safety rules to prevent any unforeseen circumstances. A complete understanding of potential hazard and risks from using chemicals or equipment’s in a lab will allow you to progress your work with ease leading to timely & effective research studies.
Let’s enlist a few potential risks and subsequent safety steps need to be followed in a chemistry laboratory.
Learn about the general hazard symbols (GHS) before using any chemicals (given in figure below). There is a list of hazard symbols which mentions about the type of hazard from a chemical. For e.g. you will find fire symbol on flammable chemicals and should be used with care. Similarly, a high-risk chemical comes with a danger symbol. Basic understanding of these symbols will allow using of chemicals safely and efficiently.

One of the common hazards of chemistry lab is suffering from chemical spills. If there is accidental chemical spills follow basic steps –
Do not throw chemicals directly into drain or dustbin; follow proper disposal guidelines to avoid any chemical contamination into the environment. The Environment Protection Agency has set certain rules for the disposal of hazardous and radioactive chemicals to prevent any environmental damage.
Fire Blanket – A fire blanket is made up of non-inflammable fiber; use it for small or large fire by covering yourself in it. However, avoid using it if a person’s clothes are on fire as it creates a chimney effect and causes more burns to a person’s body.
First Aid Kit– the kit contains disinfectants, medicines, and bandages to meet emergency first aid requirement.
Fire Extinguisher – Fire extinguishers come in different types – CO2 and Foam extinguishers. Foam extinguishers can be used for most of the fires and are often called ABC fire extinguisher. CO2 extinguisher is useful to prevent lab fires but should not be used on a person as it is extremely cold.

Safety doesn’t occur accidentally, it depends on one’s state of mind. Laboratory safety has always been a case of concern for the scientific community as it sets liability on the institutions towards individuals working in the lab as well as for those residing nearby. Thus, providing necessary training and understanding basic lab safety guidelines can prevent hazardous accidents to occur. Thus, Accident prevention should be your first call of action!
