What is a respirator?

The respirator is a device that is worn over the mouth and nose to protect the wearer from professional and environmental risks such as harmful air and gases. There are many different styles and their functionality varies according to the style. It must not be confused with a fan that actually helps in breathing, the respirator either forces air through the filter before inhaled, or adds an alternative, clean air source for duration. This is common in the workplace in fields where workers are exposed to harmful chemicals, dust, residues or gases.

The various forms of the respirator have been around for centuries and initially consisted of only a fixed woven fabric soaked in water. Modern versions, which are now commonly associated with industrial use, were first developed at the end of the 18th century. Most varieties have filters that capture incoming dust, debris and other particles in the air. They can use a mechanical cassette or chemical cassette and work air purification when they pass filters on a respiratoron the way to the nose and mouth.

For industrial use, respirator is often required according to work safety instructions. Workers who have to work in areas where one lead, asbestos or other harmful toxins or hazardous chemicals often need to be worn. Other uses include health conditions such as severe asthma or chronic obstructive pulmonary disorder (COPD) and personal protection against chemical or biological risks.

The respirator is only effective if it has been properly mounted on the wearer and the individual has undergone training or instructions for proper use and maintenance. In order to work properly, the bearer must first be mounted for his respirator. The adaptation requires a lung test from a licensed physician and includes breathing and pulmonary function and other physical evaluation. After the test, those who pass are equipped with devices that are calibrated to their poisonInnois test results based on their body during the test. Wearing someone else's respirator does not guarantee protection and can actually create another risk.
