Respirators are designed to protect against one or more of the following types of atmospheric hazards in the workplace:
- Particulate contaminants such as dirt, mists, fibre, fumes and dust.
- Gaseous or vapour contaminants, such as solvents.
- Low levels or lack of oxygen.
There are four simple principles of respiratory protection:
- Determine and select the correct respirator for the task.
- Always ensure the respirator fits your face properly.
- Ensure that maintenance is done regularly, this may include cleaning and defect recognition.
- Ensure equipment is stored properly. Most are best kept in an airtight container.
