Prevent Welding Fume from making you Sick


According to statistics, welding safety is all about being 99 percent proactive and 1 percent reactive. This means if you do not take action from the beginning then it is too late. Welding as a process vaporizes solid metal and as the metal cools, it changes into solid particles in the form of fume. The danger is  immense since fumes are actually made up of very small particles and if not removed they remain suspended in the air indefinitely. This calls for fume control.

How toxic is it

Where there is no fume control there are a lot of toxic contaminants in the air such as:

  • Lead
  • Copper
  • Fluorides
  • Iron oxide
  • Manganese
  • Mercury

There are also dangerous gases suspended such as Ozone, Nitrogen oxide and Carbon monoxide.

The health risks

Welding has been named as one of the top jobs with an increased risk of  occupational disease. One of the fumes, Manganese is extremely toxic. According to the Center for Disease Control, Manganese is present in all welding fumes. This fume is known to cause a similar disease to Parkinson’s. The symptoms being problems with swallowing, fatigue, tremors, body stiffness and headaches. Welding fume are cancer and COPD risk factors. Things are definitely worse when there is coughing, shortness of breath, dizziness and wheezing. If such symptoms occur it is an indication that a welding fume extractor is needed and your employees need serious medical attention.

Fume control

There are two ways to go about fume control in order to prevent welding fume from making you or your employees sick. You can either improve your ventilation or make use of fume control equipments.

Ventilation

We are not talking about big windows but mechanical ventilation. Of course you can have natural ventilation but the mechanical is a necessary safety precaution. There are three types of mechanical ventilation:

  • General ventilation
  • Local forced air
  • Local exhaust

When do you need to get mechanical ventilation?

  • When in confined spaces
  • When the ceiling height is below 16ft
  • When partitions obstruct proper ventilation

Hoods

These are mainly movable ducts that are placed where the actually welding is done. The aim is to provide sufficient air flow volume. This is because air flow volume is a primary factor when it comes to the effectiveness of a welding fume extractor.

Healthy workers are productive. As an employer you need to know that engaging the services of a welding fume extractor is paramount for workplace safety and not doing so may even amount to negligence.
