1. Protective eyewear worn in the lab (7) Answer: GOGGLES

Goggles are essential personal protective equipment (PPE) in any lab setting. They provide crucial protection for the eyes from splashes, spills, and flying debris. Regular safety glasses offer less protection and shouldn't be considered a substitute for goggles in many laboratory procedures.

5. A container for safely disposing of sharps (6) Answer: SHARPS

Sharps containers are specifically designed to prevent accidental needlestick injuries. They are puncture-resistant and clearly labeled for proper disposal. Improper disposal of sharps is a serious safety hazard and can lead to injury and infection.

9. Chemical hazard symbol indicating flammability (8) Answer: FLAMMABLE

The flammability hazard symbol is typically a red flame, warning of the risk of fire or explosion. Flammable materials require special handling and storage to prevent accidents. Understanding the flammability hazards of chemicals used in your lab is critical.

10. A type of fire extinguisher used for electrical fires (7) Answer: CARBON

Carbon dioxide (CO2) fire extinguishers are effective for extinguishing Class B and Class C fires, including those involving electrical equipment. They are preferred for electrical fires because they don't conduct electricity.

12. This should always be worn when handling chemicals (10) Answer: GLOVES

Gloves protect the hands from chemical exposure, burns, and contamination. The appropriate type of glove depends on the specific chemicals being handled. Some materials are resistant to certain chemicals, while others are not. Never assume a glove is suitable without checking compatibility charts.

14. A designated area for storing flammable materials (7) Answer: STORAGE

Flammable materials should be stored in designated safety cabinets or areas away from ignition sources. These areas are designed to minimize the risk of fire and explosion. Proper storage is key to preventing accidents involving flammables.

16. Used to extinguish small fires (5) Answer: BLANKET

A fire blanket is a non-flammable material used to smother small fires. They are especially useful for clothing fires or small spills that ignite. While effective for small fires, it’s crucial to know the limits of a fire blanket and evacuate if the fire grows.

17. Before beginning any experiment, always check this (9) Answer: PROCEDURE

Always carefully review the experimental procedure before beginning any work. Understanding the steps, potential hazards, and safety precautions is paramount to a safe and successful experiment. Following the written procedure reduces the chance of accidents.

20. A sudden, involuntary reaction to a stimulus (9) Answer: REFLEX

Reflex actions are involuntary responses to stimuli like heat or pain. Training and awareness can help anticipate and minimize risks associated with reflex actions in laboratory settings. Understanding that reflexes can happen in uncontrolled situations helps inform safety precautions.

21. An eyewash station is used for this (6) Answer: FLUSHING

Eyewash stations provide a crucial safety measure for flushing out chemicals or irritants from the eyes. Immediate flushing is essential in minimizing potential damage. It is important to know the location and proper use of eyewash stations in your lab.

22. A safety shower is used to remove this from your body (4) Answer: SPILL

Safety showers are used to quickly remove large amounts of chemicals or other hazardous substances from the body. They are often located near areas where larger volumes of chemicals are handled. Knowing the location and proper use of a safety shower is critical for large-scale spills.

2. Used to protect the respiratory system (8) Answer: RESPIRATOR

Respirators protect the lungs from inhaling harmful fumes, dusts, and gases. Different types of respirators are required depending on the specific hazards. Proper fit and use of respirators are crucial to ensure effectiveness.

3. Always read this before using a chemical (7) Answer: LABELS

Chemical labels provide essential information about hazards, safe handling procedures, and first aid measures. Always read the labels thoroughly before using any chemical, and pay particular attention to warnings and precautions.

4. A planned course of action in the event of an emergency (8) Answer: EMERGENCY

An emergency plan outlines procedures to follow in case of fire, chemical spills, or other unforeseen events. Emergency plans should be clearly communicated and regularly practiced through drills to ensure everyone knows what to do in an emergency.

6. A chemical resistant surface material (5) Answer: BENCH

Laboratory benches are often made of chemical-resistant materials like stainless steel or epoxy resin to withstand spills and exposure to chemicals. The surface material contributes to overall lab safety.

7. A safety feature that prevents uncontrolled release (6) Answer: SAFETY

Safety features encompass a wide range of measures designed to prevent accidents and injuries, including design, procedures, and protective equipment. A holistic safety approach greatly increases the safety of the working environment.

8. Report any accidents or incidents to this person (6) Answer: INSTRUCTOR

It’s crucial to immediately report any accidents or incidents to your instructor or supervisor. Accurate and timely reporting helps prevent future incidents and ensures appropriate actions are taken.

11. This should be cleaned up immediately (5) Answer: SPILLS

Spills of chemicals or other hazardous materials should be cleaned up immediately to prevent accidents and minimize the risk of exposure. Knowing the appropriate cleanup procedures for different substances is essential.

13. These must be worn to protect the feet (5) Answer: SHOES

Closed-toe shoes are mandatory in most labs to protect feet from spills, falling objects, and other potential hazards. Sandals or open-toed shoes are never allowed in labs due to potential for serious injuries.

15. A device used for heating substances in a lab (6) Answer: BUNSEN

Bunsen burners are commonly used in labs for heating substances. Proper use and precautions are essential to prevent burns and fires. Understanding the risks associated with open flame is a vital aspect of lab safety.

18. A protective barrier worn in a lab (6) Answer: COAT

Lab coats provide protection for clothing and skin from splashes and spills. They are a fundamental aspect of PPE in many laboratory settings.

19. The act of keeping a clean and safe work environment (8) Answer: HOUSEKEEPING

Good housekeeping practices such as proper storage, organization, and immediate cleanup are vital for preventing accidents. A clean and organized lab reduces the likelihood of spills, tripping hazards, and other accidents.
