The Top Three Welding Fume Factors to Consider

We’ve put together the top three welding fume factors to consider to help keep the workplace pollution-free when welding. In this blog, we look into what you need to consider to be HSE-compliant when welding in the workplace.

WHAT IS WELDING FUME?

The visible part of the welding fume cloud is formed from predominately metal particles, metal oxide and flux (if used), whilst the exact level of risk from the fume will depend on three main factors: 

THE TOXICITY

The toxicity of the fume varies depending on the welding process and the materials being used to weld and being welded. 

THE CONCENTRATION

The plume of fumes generated from the welding process the ones that rise from the welding point. By having local exhaust ventilation (LEV) at-source, or as close as possible to the welding point reduces the risk of fumes dispersing into the workplace, find some examples here.

THE INHALATION DURATION

It all depends on how long a member of staff is welding for. Some welders weld for a couple of hours a day, whilst others weld all day. The longer the arcing time, the more fumes are being produced, which in turn, raises the risk of airborne fume.

WHAT’S IN WELDING FUME?

Fumes given off during welding and hot cutting processes is a various mixture of airborne gases and very fine dust particles, which if inhaled, can cause ill health. Gases that can be found from the processes may include: 

  • Nitrous Oxide (NOx)
  • Nitric Oxide (NO)
  • Nitrogen Dioxide (NO2)
  • Carbon Dioxide (CO2)
  • Carbon Monoxide (CO)
  • Shielding Gas (e.g. Argon)
  • Helium (He) and;
  • Ozone (O3)

Occupational Asthma: Do you Complete Health Surveillance Assessments?

Occupational Asthma: Do you Complete Health Surveillance Assessments?

HSE conducted a series of telephone interviews to assess what percentage of companies carry out health surveillance assessments. From the research, HSE found that from 457 organisations that participated in the research, 67% reported they actively carried out health surveillance assessments. Furthermore, of those organisations which declared processes that involve exposure to asthmagens only 19% […]

In this blog, we’ve looked into how employers can protect staff working in bodywork spray workshops, the risks to health and the impact it can have on your business. Spray Paint – What is it? The HSE defines products such as paints, thinners and glues as solvents, or VOCs (volatile organic compounds). Tasks such as […]
