Final answer:
Personal protective equipment (PPE) is the first level of protection used to reduce the risk of injury or illness in hazardous environments. PPE includes items such as gloves, masks, goggles, and protective clothing. While PPE provides an important layer of protection, it is not always the best and only solution. option 2 is correct
Step-by-step explanation:
option 2 is correct Personal protective equipment (PPE) is the first level of protection used to reduce the risk of injury or illness in hazardous environments. PPE includes items such as gloves, masks, goggles, and protective clothing.
In healthcare settings, for example, healthcare workers use PPE to protect themselves and patients from the transmission of infectious diseases. PPE acts as a barrier against harmful substances or pathogens, preventing them from coming into contact with the wearer's body.
While PPE provides an important layer of protection, it is not always the best and only solution. Other control measures, such as engineering controls and safe work practices, should also be implemented to minimize risks.
Personal Protective Equipment (PPE) is considered the last level of protection. When all other control measures are in place and risks remain, PPE acts as a barrier between the user and hazards, such as infectious diseases or chemical substances. For example, in BSL-4 laboratories, highly protective suits with their own air supply ensure that lab workers are safeguarded in environments with dangerous pathogens. Meanwhile, medical personnel rely on PPE as a critical defense when working in infection zones. The equipment, however, is a supplement to other safety measures such as engineering controls and safe work practices.
