What are the different types of respiratory protection?

If your workers are exposed to airborne contaminants, they must wear appropriate respiratory protection. Respirators protect employees against various air hazards, including dust, fumes, gases, mist, and oxygen-deficient work environments.

Respirators come in two types:

1. Air-purifying respirators

This type of respirator removes air contaminants by filtering out particles or adsorbing gases or vapours in cartridge or canister. Also known as APRs, these tight-fitting units come in four types:

• full-face: covers the face from above the eyes to below the chin
• half-face: covers the face from the nose to below the chin
• quarter-mask: covers the nose and mouth
• mouth-bit: fits in the mouth and comes with a nose clip

2. Supplied-air respirators

These respirators work by supplying clean air from a compressed tank or through a tube. The air must meet certain standards for purity and moisture content, including CSA Standard Z180.1-13.

Also called SARs, this type of respirator can have tight-fitting or loose-fitting respiratory inlets. The former comes with half or full facepieces. Loose-fitting versions come in the form of hoods or helmets covering the head and neck or facepieces with rubber or fabric side shields.

Filters are an essential component of respirators because these capture air contaminants. There are three types of particulate filters based on the level of oil resistance and filter efficiency:

• R series: resistant to oil and may be used in environments with up to “one shift” where there are oil particles present
• P series: oil-proof and may be used in work environments with more than one shift where there are oil particles present
• N series: not resistant to oil and may be used when there’s no oil particles in the air

In industry jargon, one shift means eight hours of continuous or recurrent use.

What are the different hazards associated with welding?

The Employment and Social Development Canada (ESDC) categorizes the different causes of health hazards welders face into two types:

1. Chemical agents

Chemical agents come in the form of fumes, gases, or organic vapours. Here’s a summary of the different types, along with the potential health effects:

2. Physical agents

These consist of the physical hazards that come with the job, including:

Hot surfaces and environments

Unprotected contact with heated metal causes skin burns. That’s why it’s important for welders to wear safety gloves and protective clothing that provides proper insulation. Prolonged exposure to heat, coupled with strenuous activity, can raise the internal body temperature and lead to heat-related illnesses. These include:

• heat cramps
• heat edema
• heat exhaustion
• heat rush
• heat stroke
• heat syncope (fainting)

Noise

Welding involves processes that produce high noise levels. Excessive and long-term exposure to noise can lead to hearing loss. Loud noise can also have non-auditory health effects such as cardiovascular diseases, stress, and sleeping problems.

Radiation

Welders are also exposed to intense ultraviolet, visible light, and infrared radiation. That’s why appropriate eye and face protection is important.

What to consider when choosing the best welding respirators

The best welding respirators for your team must provide adequate protection for the tasks they are doing. To find the right respirators, you should consider these factors:

• the type of hazard your workers face
• filtration requirements
• fit and comfort
• the equipment’s weight
• welding-specific features

You may also have to consider the cost and maintenance of the welding respirators. Picking the right respirator enhances safety and productivity within your team, so consider that a worthy investment. After all, choosing the best welding respirators means putting your workers’ health and safety first.
