Working in a laboratory involves handling hazardous chemicals, biohazards, and other potential dangers. Having proper personal protective equipment (PPE) is absolutely essential for lab safety. PPE creates a barrier between lab workers and the substances they handle every day. The right PPE minimises exposure and protects lab personnel from injuries and illness.

Goggles Protect the Eyes
Safety goggles are a critical piece of PPE in any lab setting. They provide impact and splash protection for the vulnerable tissues of the eyes. Goggles fit securely around the eyes and seal tightly against the face. This prevents liquids, particles, and vapours from contacting the eyes under normal working conditions and accidental spills or splashes.
Goggles come in a variety of styles for different lab tasks. Simple protective eyewear includes basic safety glasses. Safety goggles with indirect venting protect against splash hazards. Chemically resistant goggles provide more comprehensive protection when working closely with corrosive chemicals. Face shields may be worn over goggles for an added layer of protection.
Selecting the proper eye protection and wearing goggles consistently prevents eye injuries and long-term vision damage.
Gloves Guard Against Skin Exposure
Gloves act as a shield between the hands and hazardous lab materials. The right gloves defend against corrosive, toxic, and irritating substances. Wearing gloves limits dermal absorption of chemicals through the skin. It also prevents injuries from sharp instruments, extreme temperatures, and other mechanical hazards.
Disposable nitrile and latex gloves are commonly used for general lab work and handling diluted chemicals. Butyl rubber, neoprene, and other specialty gloves are required for concentrated acids, solvents, and other damaging materials. Glove choice depends on dexterity needs, how well they resist permeation, and potential latex allergies. Frequent glove changes are key to avoid chemical breakthrough.
Proper glove use lowers the risks of burns, blisters, cuts, rashes, and chronic skin conditions. Removing gloves safely prevents cross-contamination.
Lab Coats Provide an Outer Barrier
Lab coats and gowns are vital PPE that covers the body, arms, and legs. A lightweight cotton lab coat is suitable basic protection during routine lab procedures using diluted chemicals and biological agents. It shields the wearer’s skin and personal clothing from incidental spills and stains.
Other lab coat materials offer greater liquid resistance. Disposable polyethylene coats provide single-use protection against blood-borne pathogens and highly hazardous chemicals. Rubber, neoprene, or other coated gowns give an extra level of impermeability for working with large quantities of corrosive liquids.
Lab coats also have long sleeves and snap or button closures to minimise skin exposure. Frequent laundering keeps coats free of chemical residue. Proper use reduces bodily injury and helps prevent the spread of contamination.
Additional PPE Safeguards
Other specialised PPE may be mandatory depending on lab hazards. Respirators or full face masks protect personnel from toxic dusts, vapours, and gases. Face shields provide splash protection beyond what goggles offer. Chemical-resistant aprons, booties, and full bodysuits are necessary when handling extremely hazardous compounds.
Effective PPE Enhances Lab Safety Culture
Personal protective equipment forms the last line of defence against workplace hazards when engineering controls and proper lab technique fail. PPE must be suited to each procedure and used consistently by all lab personnel to be truly effective. A comprehensive PPE programme improves lab safety culture, backed by policies for proper selection, training, and enforcement. With the right PPE and safety practices, lab staff can handle hazardous materials confidently every day.
