skin burn - complete destruction of the scarfskin
deep burn - destruction of a part of the skin along with sebaceous glands
total burn - complete destruction of the skin
Means of protection against the hazards mentioned above are:
wearing of protective clothing marked as flame-retardant. These are gloves, a leather apron,
protective footwear, a hat as well as face and eye protection.
using of manual or mechanical methods of loading/unloading a hot material to protect the
operator against high temperature;
protecting the operator's eyes by using special protective glasses with a darkness level of min. 6
DIN.
3.8.2 HAZARDS THAT MIGHT BE CAUSED BY SPARKS AND SPLITS
During cutting and piercing, sparks or splinters are produced which can cause burns or a fire.
As a means of protection against spatters you should:
use protective clothing marked as flame-retardant. These are gloves, a leather apron, protective
footwear, a hat, face and eye protection
not storing flammable substances near the device's working area
separate the work place with special protective curtains from other work stations
comply with fire regulations
ensure that the fire extinguisher is in place
3.8.3. HAZARDS THAT MIGHT BE CAUSED BY GASES AND SMOKES
When machine operator is exposed to the fumes generated during cutting process for a long time, it
might cause various diseases of the respiratory system. Dust comes into the human’s body mainly
through the respiratory tract. This way, to get into the body system, is used by very small particles
that pose the greatest threat to humans. A common feature of all industrial dusts is irritating effect
on upper respiratory tract of mucous membranes, e.g. iron oxides.
The effects of the above may be:
eye and skin irritation
nausea
metallic fever
headaches and dizziness
respiratory disorders
As a means of protection against gases and smoke you should:
ventilate the room in which the machine works
extract fumes and gases that were produced during the process
set the water level so that water comes into contact with the cutting material (applies to water
tables and plasma cutting)
control and do not exceed the max pollution values in the room where machine works
comply with all regulations regarding the operation of gas cylinders and gas cutting torches
3.8.4. RISK OF INFRARED, UV PROTECTION AND VISIBLE RADIATION
During plasma or gas cutting, there is a high radiation due to the burning of gases and the formation
of an electric arc.
The effects of radiation can be:
redness, damage to the scarfskin
faster ageing process
change of skin colour
