Interpretation:
Safety precautions that need to be taken while following the given safety symbols needs to be explained.
Concept introduction:
Safety precautions are the actions conducted well in advance to protect against possible danger, failure, injury or a safeguard when the person is using heavy machinery. Safety symbols are the meaningful graphical representations that warn of or identify hazards associated with the location or item.
Answer to Problem 24SSC
Heat resistant gloves indicate the use of oven mitt while handling hot materials. Heating test tube indicates using a tong, plastic gloves indicate using disposable gloves and no flames indicate to be away from flame or sparks when handling flammable materials.
Explanation of Solution
Given information:
Graphic symbols of heat resistant gloves, heating test tube, plastic glove and no flame.
Heat resistant gloves: This symbols advices to wear oven mitt or other hand protection while handling hot materials such as hot glassware or plates.
Heating test tube: This symbol indicates to use a clamp or tongs to pick up hot glassware and should not touch the heating test tube with bare hands.
Plastic gloves: Presence of this symbol indicates the person to wear disposable plastic gloves while working with dangerous chemicals or organisms. After the work is done, dispose of the gloves in the dustbin.
No flames: This symbols is represented by a X over a flame. It indicates the person to be away from flames, sparks or other expose heat sources while using flammable materials.
Thus, heat resistant gloves indicate the use of oven mitt while handling hot materials. Heating test tube indicates using a clamp, plastic gloves indicate using disposable gloves and no flames indicate to be away from flame or sparks when handling flammable materials.

- Help with a periodic table task.' Procedure Part 1: Customizing a Periodic Table Use a textbook or other valid source to determine which elements are metals, nonmetals, metalloids (called semimetals in some texts), alkali metals, alkaline earth metals, transition metals, halogens, and noble gases. Download and print a copy of the Periodic Table of Elements. Use colored pencils, colorful highlighters, or computer drawing tools to devise a schematic for designating each of the following on the periodic table: Group numbers Period number Labels for these groups: alkali metals, alkaline earth metals, transition metals, inner transition metals (lanthanides and actinides), other metals, metalloids (semimetals), other nonmetals, halogens, and noble gases Metals, nonmetals, and metalloids Note: Write the group and period numbers and color/highlight each element for categorization. Be sure to include a key for the schematic.
