Final answer:
In laboratories containing hazardous, biohazardous, or radioactive material, personal protective equipment (PPE) should be worn. The correct option is D.
Step-by-step explanation:
In laboratories containing hazardous, biohazardous, or radioactive material, personal protective equipment (PPE) should be worn. PPE includes items such as gloves, lab coats, and protective suits. These protective measures help to minimize the risk of exposure to harmful substances and ensure the safety of the individuals working in the lab. In laboratories containing hazardous, biohazardous, or radioactive material, the appropriate attire is personal protective equipment (PPE).
PPE includes items such as lab coats that cover the body appropriately, gloves, face shields, and sometimes full-body suits, especially in high-containment laboratories like BSL-4 facilities. Loose clothing, open-toed shoes, and short lab coats are not suitable as they do not provide adequate protection. For example, when working with radioactive materials or in BSL-4 laboratories, workers wear specialized suits that prevent contamination and provide a protective barrier against biological agents.
Such suits are designed to protect the wearer from potential exposure to biological agents and may have their own air supply and maintain a positive pressure to prevent contaminated air from entering the suit. While white coveralls might not protect against high-energy radiation, they can prevent contamination by blocking radioactive particles from reaching the skin or personal clothing. Items like lab coats, coveralls, and gloves provide a physical barrier, reducing the risk of direct skin contact with hazardous substances, including low-level radioactive waste such as contaminated tools and wiping cloths.
