Preparing Your Respirator

Using a Full Face Respirator

A full face respirator offers a high level of protection because it safeguards both your lungs and your eyes. Unlike a standard half-mask respirator combined with separate eye protection, a full face respirator seals around the entire face, keeping hazards out more effectively.

The main advantage is that dust, particles, splashes, and airborne contaminants are kept outside the mask. This prevents substances from entering your lungs and stops debris or chemicals from reaching your eyes. While full face respirators are more expensive than basic respirators and face shields, they combine all protection into a single, reliable unit.

This example shows one brand of full face respirator. There are many brands available, but the principles of use and safety checks are the same.

Filters and Preparation

Before use, make sure you have the correct filters for the task. Different filters protect against different hazards, such as dust, vapours, or biological contaminants.

Filters come sealed in packaging with full instructions. Always:

• Read the manufacturer’s instructions
• Check the filter type is suitable for the hazard
• Confirm the CE markings
• Check the expiry date, as filters degrade over time

If you keep spare filters, always store them in their original packaging. Do not leave filters loose or exposed, as this can damage them or reduce their effectiveness.

Inspecting the Mask

Before fitting the respirator, carry out a visual inspection:

• Check the face seal is intact and undamaged
• Ensure there are no cracks or splits in the mask body
• Check the visor is clear and free from heavy scratches
• Confirm the exhalation valve is unobstructed

The internal seal around the mouth and nose improves breathing efficiency and helps prevent fogging of the visor. If the seal is damaged, the mask must be replaced.

Removing Protective Film

New respirators are supplied with protective plastic film on the visor:

• Peel off the outer protective film
• Remove the inner protective film using the pull tab

Once removed, ensure the visor is completely clear.

Fitting the Filters

Filters attach to both sides of the mask:

• Align the filter with the connector
• Push and rotate until it clicks into place
• Repeat on the opposite side

Both filters must be fitted. Using only one filter allows unfiltered air to enter through the open side and makes the respirator ineffective.

Preparing to Fit the Mask

Before putting the respirator on:

• Loosen all head harness straps
• Ensure the mask is clean and dry
• Check the seal area once more for damage

Once fitted, the mask should sit comfortably and securely, creating a firm seal around the face.

Storage and Care

Full face respirators should be stored carefully to prevent damage. The visor is usually made from Perspex and can scratch easily.

When not in use:

• Store the mask in a protective bag or box
• Wrap it in a soft cloth or towel if necessary
• Keep it away from sharp objects and direct sunlight

Key Safety Points

• Always use the correct filter for the hazard
• Check expiry dates on filters
• Inspect the mask before every use
• Fit filters on both sides of the respirator
• Replace the mask if seals or visor are damaged

A correctly fitted and well-maintained full face respirator provides excellent protection and significantly reduces the risk of inhalation or eye exposure to hazardous substances.
