Question

State 4 reasons why resistant materials require particular techniques for the safe handling and use.

Answer 1

Resistant materials require specific techniques for safe handling and use due to the need for protection from hazardous substances, control of temperature, prevention of contact with air and water, and protection from radiation.

Step-by-step explanation:

Resistant materials require particular techniques for safe handling and use for several reasons:

1. Protection from hazardous substances: Some resistant materials, such as chemicals or radioactive materials, can be harmful to human health. Specific techniques need to be used to prevent exposure to these substances, such as wearing personal protective equipment or using containment systems.
2. Control of temperature: Certain materials require specific temperature conditions for safe handling. For example, very low temperatures may necessitate the use of refrigeration or liquid nitrogen to cool the materials below their critical temperatures.
3. Prevention of contact with air and water: Some materials, like potassium, need to be stored in sealed containers or submerged in mineral oil to prevent contact with air and water, which can react with the material and cause hazards.
4. Protection from radiation: Materials that emit radiation, like radioactive materials used in nuclear reactors, require special handling to protect against exposure. This includes using shielded containers and protective shielding for personnel.

Answer 2

Particular techniques are needed for the safe handling and use of resistant materials to prevent injuries from sharp objects, protect against harmful chemicals, avoid burns or fires from heat, and prevent electrical shocks due to high resistivity.

Step-by-step explanation:

There are four reasons why resistant materials require particular techniques for the safe handling and use:

• Resistant materials can include sharp objects that may cause cuts or punctures. Therefore, specific safety measures, such as protective gloves and careful handling, are required to prevent injuries.
• Chemicals used in labs can be corrosive, toxic, or react violently under certain conditions. Safe handling includes using appropriate containment and protective gear such as lab coats and safety goggles.
• Heat-intensive processes such as using Bunsen burners or autoclaves require heat-resistant gloves and careful monitoring to prevent burns or fires.
• Electricity and materials with high resistivity require caution to prevent electrical shocks. Insulated handling tools and proper grounding are essential when handling such materials.

Following these guidelines ensures personal safety as well as environmental safety by minimizing the risks associated with hazardous materials and chemical reactions.
