What happens to workers when exposed to halocarbons at levels greater than recommended thresholds?

1. They may develop a tolerance over time

2. They may experience fatigue and weakness

3. They may suffer from shock and decreased blood pressure

4. They will not experience any side effects

The correct answer is: They may suffer from shock and decreased blood pressure

When workers are exposed to halocarbons at levels exceeding the recommended thresholds, they can experience serious adverse health effects. One of the potential outcomes of such exposure is suffering from shock and decreased blood pressure. Halocarbons, which include a variety of chemical compounds, can affect the cardiovascular system, leading to symptoms such as hypotension (low blood pressure) and shock, which is a critical condition characterized by insufficient blood flow to the organs. This reaction occurs because halocarbons may disrupt the normal functioning of the heart and blood vessels, causing a reduction in blood pressure and potentially leading to shock if exposure is significant and prolonged. This highlights the importance of adhering to safety guidelines and exposure limits to safeguard workers' health and ensure a safe working environment. Other choices suggest various non-critical reactions or the absence of side effects, but these do not accurately reflect the serious health implications that can arise from high-level exposure to halocarbons. The potential for shock and decreased blood pressure emphasizes the need for preventive measures and careful monitoring in workplaces where these substances are used.
