Lab Rules and Safe Habits 26

Alert Wide awake and watching what is going on around you.
Clean up To wipe the bench, put the equipment back and leave the space ready for the next class.
Dispose To get rid of waste the right way, in the container the teacher names.
Evacuate To leave a room or a building quickly and calmly because of danger.
First aid Quick, simple care given to a hurt person before a nurse or doctor arrives.
Flush To wash out with plenty of running water, as an eyewash does for eyes.
Food Snacks, lunches and gum. None comes into a lab, open or closed.

How this list was compiled: Own work: the word list and every clue were written for this page. The facts in the clues were checked on 2026-09-19 against the School Chemistry Laboratory Safety Guide (https://www.cpsc.gov/s3fs-public/NIOSH2007107.pdf), the OSHA hazard pictograms (https://www.osha.gov/hazcom/pictograms) and Wikipedia (https://en.wikipedia.org/wiki/Laboratory_safety). A vocabulary list: your school's own lab rules come first. Spellings follow the American Heritage Dictionary (https://www.ahdictionary.com/). Some clues were reworded on 2026-09-20, and any fact that changed was checked against Wikipedia the same day. Licence: own work

How it works

This laboratory word search covers both halves of a school science lab: 80 safety words and 50 equipment words, 8 lists in all. It opens on 16 of 24 key terms, Goggles, Beaker and Tongs among them.

Read the full guide

A lab safety word search for the first week

For a lab safety word search, stay with three lists in the Start from a list row under the puzzle. They are Safety Gear and Stations (22 words), Hazards and Warning Labels (32) and Lab Rules and Safe Habits (26). Glassware and Measuring (27) and Burners, Stands and Tools (23) name the equipment, from Beaker and Meniscus to Tripod and Wire gauze.

Easy and hard lab lists

Easy Science Lab holds 38 words of 3 to 5 letters, such as Acid, Sash and Tongs. Hard Science Lab holds 42 of 9 to 12 letters. Of the 130 entries, 31 are two words. The grid drops the space: Fume hood is found as FUMEHOOD. For single words only, pick Science Lab Key Terms.

Extinguisher fills 12 squares, so the key terms need a grid of 12 by 12 or more.
Erlenmeyer is a surname: the clue says a German chemist made the cone-shaped flask in 1860.

Questions and answers

Does this word search replace a lab safety lesson?

No. It is a vocabulary sheet. It helps pupils read and spell the words on the lab rules handout and on chemical labels. Nothing here is a safety instruction. Your school's rules and the teacher's own briefing come first.

Is it a science safety word search or a lab equipment one?

Both, in separate lists. Gear, hazards and rules add up to 80 safety words. Glassware and burners add up to 50 equipment words. New puzzle keeps picking from the list you chose.

What do Danger and Warning mean on a chemical label?

They are the two signal words. A label carries one of them: Danger for the more severe hazards, Warning for the less severe. Both are in Hazards and Warning Labels, beside Pictogram, Flammable and Corrosive.

Can pupils solve the lab puzzle from definitions?

Yes. Tick Show clues, not words, in More options. Eyewash then reads "A station that rinses the eyes with water after a chemical splash." The printed sheet carries the clues in place of the words.

Is the laboratory word search free to print?

Yes, with no sign-up. Two pages come out, on Letter or A4: a Name and Date line, the grid and the word list, then the answer key. For a PDF, pick Save as PDF in the print window.
