Final answer:
To ensure adequate ventilation and wear appropriate PPE, it's important to consider different situations such as industrial workplaces and laboratories. Employers must provide a safe workplace and inform workers about potential hazards and proper PPE usage.
Step-by-step explanation:
When it comes to ensuring adequate ventilation and wearing appropriate PPE (personal protective equipment), it is important to consider various situations. In industrial workplaces, workers may be exposed to different chemicals such as chlorine or phosphorus, which require specific PPE to protect against their toxic and corrosive characteristics. Similarly, in laboratories, working with hazardous substances may require wearing protective suits with an independent air supply. It is crucial for employers to provide a safe workplace and inform workers about potential hazards and the proper use of PPE.
