Rules for safe experiments. Here are some of the most popular ways students use Lab Safety Checker every day:
The Lab Safety Checker is your go-to resource for understanding and remembering safety rules in science laboratories—whether you're doing GCSE practicals, A-Level experiments, or KS3 investigations. Every year, preventable accidents occur because students misjudge hazards or skip safety steps. This tool covers UK school lab standards, PPE requirements, emergency procedures, and how to identify and report hazards. Applaa's Lab Safety Checker is aligned with school safeguarding policies and the Health and Safety at Work Act, so you're learning rules that protect you and your classmates. Using the tool before each practical means you'll impress your teacher, build good habits for university or careers in science, and most importantly, keep yourself and others safe. Many students underestimate lab hazards until something goes wrong—this tool empowers you to spot risks before they become incidents.
Before every practical, use the tool to check the specific hazards you'll encounter (chemicals, heat, electricity, sharp objects, etc.). For each hazard, the tool shows the associated risks and control measures. Wear the required PPE (lab coat, goggles, gloves) every time, without exception—even 'quick' tasks pose risks. Familiarise yourself with your school's lab location: where's the eyewash station, first aid box, fire extinguisher, and emergency exit? Follow your teacher's instructions exactly; they've assessed the specific risks of that practical. After the practical, dispose of materials correctly and clean your workspace. Use the tool's 'hazard reporting' feature if you notice broken equipment, spilled chemicals, or anything unusual—reporting is not 'telling on someone'; it's protecting everyone.
The biggest mistake is assuming 'it won't happen to me'—every accident victim thought that too. Some students remove goggles 'just for a second' or work without a lab coat to 'move faster', exponentially increasing risk. Others ignore chemical labels or mix incompatible substances out of curiosity, creating dangerous reactions. Eating, drinking, or applying cosmetics in the lab is strictly forbidden but tempts rushed students. Not reporting hazards because you don't want to 'get someone in trouble' means others face the same risk. Overconfidence after completing one practical safely leads to complacency; every experiment is a fresh risk assessment. Finally, students sometimes hide small injuries (paper cuts, chemical splashes) instead of reporting them—this prevents proper treatment and obscures patterns in lab incidents.

Because accidents happen in seconds and can cause permanent eye damage or blindness. Many eye injuries occur from unexpected splashes or reactions, not dramatic explosions. Goggles are your only line of defence, and your eyesight is irreplaceable. No experiment is worth risking vision.
Call for a teacher immediately. Rinse the eye gently at the eyewash station for at least 15 minutes (yes, 15!) whilst keeping the eyelid open. Get medical help—don't wait to see if it feels better. Severe eye injuries can seem mild at first but worsen quickly.
No, never. Even if you think the area looks clean, chemical residue is invisible. Food can be contaminated, leading to poisoning. Eat in the canteen or outside. Some chemicals also damage skin; you could transfer them to your food without realising.
Tell your teacher or lab technician immediately if you notice broken equipment, spills, or anything unusual. Be factual ('The Bunsen burner dial is stuck') without blaming anyone. Schools have systems to fix hazards quickly; reporting is how the system works. You won't get in trouble—you're being responsible and protecting classmates.
