First of all , to assess the hazards in welding will have to take into account several factors:
- What type of welding we are using
- What are the joining base metal
- What metal we use for welding, which molten and gas type
- How long will we be exposed to these risks
- What type of ventilation have
- What weather conditions, if we are on the outside working place.
We could diversify by type of welding, but as follows we expose the most remarkable hazards in welding in general and on which our tissues can provide adequate protection (in some of them):
- Inhalation of smoke and suspension particles by type and where the operation is done
- Lack of oxygen in the gas mixture of oxygen consumed around us
- Noises
- Eye damage and skin
- Ultraviolet (UV) and Infrared (IR)
- Burns
- Contact with high temperature areas
- By radiation (intense heat due to producing bindings & union processes)
- Metal splash
- Entrapment / confined spaces
Stepping on sharp objects around us - Ergonomic
- Falls from height or at ground level
- Direct or indirect Electricity
- The use of the equipment, leave them in place working (for the electrostatic charge that could be generated)
- Or by some kind of electrical failure that may occur in the equipment
- Fire and explosion
- Combustible materials
- Gas leaks
- Return of the flame
- Pressure machinery
- Sometimes Atmospheres over-oxygenated
- Work in containers which have held combustible materials ( high risk of explosion materials)
HINT: You should never performed the welding operation with contact lenses
