Welders need to be protected against hazardous fumes. Welders can be protected by systems for source extraction and general filtration and ventilation. They can also choose to be protected by respiratory protective equipment (RPE) for example welding helmets with a fresh air supply. Supplied air respirators are known to provide the best all-around protection for the welders themselves.

RPE only protects the welder, when choosing this method of extraction don’t forget to consider other people in the workplace. Are you protecting them? Or would it be better to look at effective at source welding fume capture or general air cleaning.

This blog post looked at several important aspects which need to be considered when selecting the most appropriate type of respirator for your circumstances.

Officially approved

First things first, always make sure that respirators have been officially approved by relevant authorities and ensure they meet specific standards. For the first-time user all respirators are uncomfortable to a certain degree. Selecting the right type for you will contribute to making it more comfortable for you. Consult a supplier before making your final decision to ensure the correct model and make for you.

Determine gases and fumes

Determine which gases and fumes represent the most serious problem for the job which you are about to do. With protective equipment consult manufacturers or suppliers for advice on the most suitable type(s) of respirator.

Medical conditions

Ensure any prior medical conditions will not detartrate with the use of a respirator. Welders / Workers who use respiratory protective equipment should ensure they are medically fit to use the equipment by having a medical assessment.

Correct filtration cartridge

The respiratory hazard must be combated by the respirator you select. You must select the correct filtration cartridge on air purifying masks to protect from low levels of metal fumes, welding gases and organic vapours. The respirator supplier will be able to assist with the selection of the correct cartridge.

Change cartridges and filters

When using an air-purifying mask to protect yourself from fumes containing metals such as chromium and cadmium, the cartridges with disposable filters may need to be changed frequently. Consult the supplier about how often cartridges need to be changed.

Ensure it fits

Once you have selected an appropriate type of respirator that will properly protect you from the respiratory hazard, you must select the specific model to meet your needs. As an example, fit is extremely important. A poorly fitting respirator allows hazardous materials to leak into the air you are breathing. Ensure that the respirator has a good seal. Can it be adjusted? Does it come in multiple sizes?

Unrestricted clear views

Check that the respirator provides clear and unrestricted views. Will you need to wear glasses or googles at the same time? Can you wear a hard hat or welding helmet at the same time? Would a welding helmet with built-in respiratory equipment be a better option?

Movement and speech

Does the respirator provide enough freedom of movement and allow for verbal communication when these are necessary? How noisy Is the respirator? Does it interfere with hearing?

Does the respirator provide a speaking diaphragm or a way to communicate electronically? Can others make out what you are saying when you communicate through these devices? How far away can you be heard? The answers to these questions may be important in situations where you are working in a confined space and away from others.
