Explanation:

Question about "Liquids must kept be in a sealed container when they are heated."

The correct sentence structure should be "Liquids must be kept in a sealed container when they are heated." The original sentence has a wrong word order ("kept be" should be "be kept"). Also, not all liquids need to be in a sealed container when heated (e.g., some liquids like water in an open beaker can be heated for certain purposes, but for volatile or dangerous liquids, sealed is better, but the statement is too absolute). So the answer is False.

• A safety shower is for washing off chemicals, not for putting out clothing fires.
• Baking soda is good for small chemical fires, not typically for clothing fires.
• A fire extinguisher may not be the best for clothing fires as it can cause injury or spread the fire if not used properly.
• A fire blanket is designed to smother the fire on a person's clothing by cutting off oxygen, which is the best method.

• Wiping with a paper towel can spread the chemical or cause more damage.
• Flushing the affected area with copious amounts of water is the standard first - aid procedure to dilute and remove the corrosive chemical.
• Doing nothing will let the chemical damage the skin.
• Using butter or baking soda is not the correct first - aid for corrosive chemical spills on the skin.
