415C Kitchen Safety — Questions and Answers
Question 1: What type of fire extinguisher is required for a commercial kitchen in Canada where cooking oils and fats are used?
- Class A (ordinary combustibles)
- Class B (flammable liquids)
- Class K (kitchen cooking media) (Correct answer)
- Class C (electrical)
Correct answer: Class K (kitchen cooking media)
Class K fire extinguishers are specifically designed for fires involving cooking oils, fats, and greases common in commercial kitchens. They use a wet chemical agent that creates a foam blanket to suppress the fire and prevent re-ignition.
Question 2: What should a cook do first if a grease fire starts in a pan on the stove?
- Throw water on the fire
- Cover the pan with a tight-fitting lid to smother the fire (Correct answer)
- Move the pan to the sink
- Fan the flames to extinguish them
Correct answer: Cover the pan with a tight-fitting lid to smother the fire
The first response to a grease fire is to cover the pan with a tight-fitting lid or baking sheet to cut off the oxygen supply, then turn off the heat. NEVER use water on a grease fire — water causes the burning oil to splatter violently, spreading the fire.
Question 3: When carrying a knife in a commercial kitchen, what is the correct and safest method?
- Hold the blade pointing up above shoulder height
- Carry the knife at your side with the blade pointing down and the edge facing behind you (Correct answer)
- Wrap it in a towel and carry it at chest height
- Hold it out in front of you so others can see it
Correct answer: Carry the knife at your side with the blade pointing down and the edge facing behind you
A knife should be carried at your side with the blade pointing straight down, the sharp edge facing behind you, and your arm held slightly away from your body. Verbally alert others by saying 'sharp behind' or 'knife behind' when moving through the kitchen.
Question 4: What is the safe way to lift a heavy stockpot of hot liquid?
- Grip the handles and lift with your back
- Bend at the knees, keep the back straight, grip both handles firmly, and lift with your legs (Correct answer)
- Ask someone to pour the liquid out first
- Use one hand on the handle and slide it across the stove
Correct answer: Bend at the knees, keep the back straight, grip both handles firmly, and lift with your legs
When lifting heavy kitchen items, bend at the knees, keep your back straight, grip both handles firmly (using dry towels or oven mitts if hot), and lift with your legs. Ensure a clear path before moving and communicate with colleagues.
Question 5: What type of footwear is required in a professional kitchen in Canada?
- Any clean athletic shoes
- Non-slip, closed-toe shoes with liquid-resistant uppers (Correct answer)
- Steel-toed boots
- Rubber sandals with ankle straps
Correct answer: Non-slip, closed-toe shoes with liquid-resistant uppers
Professional kitchen workers must wear non-slip, closed-toe shoes with liquid-resistant uppers to prevent burns from hot liquids, cuts from fallen knives, and slips on wet floors. CSA-approved slip-resistant soles are recommended.
Question 6: What is the correct procedure when a co-worker receives a burn from hot oil in the kitchen?
- Apply butter or cooking oil to the burn
- Immediately cool the burn under cool running water for at least 10 minutes, then cover with a sterile dressing (Correct answer)
- Apply ice directly to the burn
- Pop any blisters that form
Correct answer: Immediately cool the burn under cool running water for at least 10 minutes, then cover with a sterile dressing
The correct first aid for a burn is to immediately cool it under cool (not cold) running water for at least 10 minutes to reduce tissue damage. Cover with a sterile, non-adhesive dressing. Never apply butter, oil, ice, or pop blisters, as these can worsen the injury.
