Final answer:
It is true that proper respiratory equipment should always be worn when mixing concentrates due to the potential release of harmful chemicals. Safety measures include following manufacturer’s instructions, ensuring good ventilation, and understanding how biological, chemical, and physical pollutants can negatively impact respiratory health.
Step-by-step explanation:
The statement that proper respiratory equipment should always be worn when mixing concentrates is true. Concentrates often contain chemicals that can be harmful if inhaled, and without proper ventilation and the use of appropriate respiratory equipment, there is a risk of respiratory injuries or illnesses.
Always follow the manufacturer's instructions for safe use, and ensure that the area is well-ventilated to avoid the accumulation of potentially hazardous fumes.
Three common types of things that can enter the respiratory system and cause illness or injury include:
- Biological pollutants like bacteria, viruses, and fungi, which can lead to infections such as pneumonia.
- Chemical pollutants, including volatile organic compounds (VOCs) and other inhaled carcinogens, which can cause a reduction in the number of alveoli and lead to chronic respiratory diseases like Chronic Obstructive Pulmonary Disease (COPD).
- Physical pollutants such as dust, asbestos, and silica particles, which can trigger asthma attacks where airways narrow and fill with mucus, and may lead to long-term conditions like asbestosis.
