Wear protective clothing
Wearing protective clothing is an essential step in safeguarding your health when faced with occupational pollution hazards. The type of protective clothing you require will depend on the specific hazards present in your work environment.
For instance, if you work in an environment with hazardous chemicals, it is crucial to wear the appropriate protective gear, such as chemical-resistant gloves, aprons, and eye protection. The National Institute for Occupational Safety and Health (NIOSH) provides valuable resources, including a guide to selecting the right protective clothing materials for specific chemicals. Additionally, respiratory protection is vital when dealing with toxic chemicals or in situations where engineering or work practice controls are not feasible.
Healthcare professionals, such as nurses, face unique hazards related to radiation exposure. To protect themselves, they should wear specialised clothing, such as lead aprons, thyroid shields, and lead gloves, which effectively shield the body from radiation. Nurses should also minimise their time spent in radiation zones and maintain a safe distance from radiation sources.
In any occupation, it is important to have the necessary vaccinations to protect against common biological agents. For example, vaccines can safeguard workers from hepatitis B, which is a significant concern in healthcare settings.
By donning the appropriate protective clothing and adhering to specific guidelines for your industry, you can significantly reduce your exposure to occupational pollution hazards and safeguard your health.

Keep distance from radiation sources
Radiation exposure is a serious health risk for people working in healthcare, such as nurses, and in other sectors where radiation sources are present. Radiation can cause occupational cancer and other non-communicable diseases (NCDs). It is therefore important to know how to protect oneself from radiation exposure.
The three principles of radiation safety are time, distance, and shielding. Firstly, limiting the time spent in the radiation field will reduce the amount of radiation absorbed. Secondly, increasing distance from the radiation source is a very effective way to reduce radiation exposure. The intensity of radiation exposure decreases as one moves further away from the source. For example, doubling the distance from the radiation source reduces radiation exposure not by half but to a quarter. Thirdly, inserting a shield, such as a barrier of lead, concrete, or water, between oneself and the radiation source will reduce or eliminate the radiation dose received.
To keep distance from radiation sources, it is recommended that nurses minimise the time spent working in radiation zones. In addition to increasing the distance from the radiation source, one should also wear protective clothing, such as lead aprons, thyroid shields, and lead gloves, to further shield the body from radiation. It is also important to ensure that the workplace has radiation standards in place with regular training and reviewing.
In a radiation emergency, such as a large release of radioactive material, it is crucial to follow the advice of emergency responders and officials. This may include taking shelter in a building, moving to the middle of the building or to a basement, and staying away from doors and windows.

Reduce energy use at home
Reducing energy use at home is an important way to protect yourself from occupational pollution hazards. Here are some detailed and direct instructions to help you achieve this:
Firstly, be mindful of the sources of indoor air pollution. For example, cooking gas and radon can be hazardous to your health. If you use gas for cooking, ensure that you have adequate ventilation in your home, such as exhaust fans that vent outdoors. These fans are especially important when cooking, as they can remove pollutants produced during frying or when using a gas stove. Similarly, if your heating system and water tanks are powered by gas or oil, have them checked for carbon monoxide (CO) leakage and ventilation each year. Carbon monoxide is a dangerous and potentially deadly indoor air pollutant, so install functioning CO alarms outside bedrooms and ensure they are regularly tested and replaced according to the manufacturer's instructions.
Secondly, be cautious when using household chemical products. Always read the labels and follow the instructions carefully, especially when children and pets are present. Understand the hazard symbols and wear the recommended personal protective equipment to prevent the spread of substances onto other objects and people. Take leftover chemical products to your local hazardous waste disposal depot, and bring unused or expired medications to your local pharmacist for proper disposal.
Additionally, take measures to reduce the presence of mould in your home. Mould grows in damp or wet areas and can spread through air ducts. Keep your indoor spaces well-ventilated and clean up small amounts of mould with water and dish soap. If you suspect lead contamination in your water, reduce your exposure by letting your tap water run until it is cold, and use this water for drinking, cooking, and preparing baby food.
Furthermore, consider the impact of your home's construction on indoor air quality. Modern homes are often better sealed, reducing the amount of fresh air that seeps in. During periods of high outdoor air pollution, close your windows and use air conditioning if possible. However, when indoor activities generate pollutants, such as during renovations or when using paint, open the windows to allow fresh air circulation. Choose low-emission paints, varnishes, and building products to minimise the release of volatile organic compounds (VOCs) into the air.
Finally, some general energy-saving practices can help improve air quality and reduce pollution. Limit the use of electrical appliances and heating or cooling systems when possible. Opt for natural ventilation by opening windows during cooler parts of the day. Encourage the use of renewable energy sources, such as solar power, if available. By following these instructions, you can effectively reduce energy use at home and protect yourself from occupational pollution hazards.

Avoid exercising outdoors when pollution levels are high
When air pollution levels are high, it is recommended that people avoid exercising outdoors. This is because physical activity increases your breathing rate, introducing more pollutants into your body. For example, a review of 16 papers found that exercising outdoors in air pollution can result in short-term lung function impairments.
The Environmental Protection Agency's Air Quality Index (AQI) is a useful tool for checking the air quality in your area. Experts recommend exercising outdoors only when the AQI is between 0 and 50, indicating "good" air quality and minimal risk of air pollution. If the AQI is between 51 and 100, indicating "moderate" air quality, outdoor exercise is mostly acceptable, but those with chronic health conditions or increased sensitivity to pollution should avoid it. When the AQI reaches 101 and above, indicating "unhealthy" levels of air pollution, outdoor exercise is generally not encouraged.
If you are unable to check the AQI, there are other ways to estimate pollution levels. For example, if you live in an area affected by wildfire smoke or ozone during hot and sunny weather, it is likely that pollution levels are high. Similarly, if you live in an urban area, busy traffic times of day will typically have higher pollution levels due to emissions from cars.
If you do choose to exercise outdoors when pollution levels are high, there are a few precautions you can take to minimize your exposure to pollutants. Firstly, opt for lower-intensity workouts, as higher-intensity exercises increase the amount of air you breathe in, and therefore the amount of pollution inhaled. Secondly, try to find areas with lower pollution levels, such as nature trails, and avoid busy roads.
